What Mold Remediation Costs in New Jersey Against the National Guides (2026)

The national guides agree with each other. Angi's July 9, 2026 average is $2,368, with most jobs between $1,223 and $3,757, built from surveys of its customers. Servpro's cost page quotes HomeAdvisor's national data at the same $2,368 average (September 14, 2026), and HomeGuide puts the usual job at $1,500 to $6,000 (February 5, 2026). Angi does not price New Jersey cities, but it does price the two metros on either side: New York City at $1,314 to $3,783, average $2,541, and Philadelphia at $1,298 to $3,661, average $2,438 (both October 20, 2025).

The New Jersey figures sit higher. typicalprices.com's Newark estimator puts most jobs at $2,407 to $9,386 with a typical job near $4,753 (October 5, 2026), and its Edison page shows the identical numbers, so read them as a statewide model, not town quotes. By arithmetic, that typical figure is about twice Angi's national average. Advanced Disaster Recovery's New Jersey table (April 26, 2026) prices by area: $500 to $3,500 under 10 square feet, $2,500 to $8,000 for 10 to 100, and $5,000 to $15,000 for 100 to 300. The same company says North Jersey (Bergen, Essex and Hudson counties) runs 10 to 15 percent above South Jersey and the Shore.

So a New Jersey quote between about $2,400 and $9,400 for a contained job in one area sits inside the published New Jersey figures, and a quote above $15,000 for an area under 300 square feet sits above every New Jersey figure on this page. What decides where you land is the size of the area, where it is, how much has to be torn out and rebuilt, and whether the water source is already fixed.

Mold Remediation Cost per Square Foot, and the Size That Decides Who Does It

Remediation is priced by the area of growth. Angi puts most companies at $10 to $25 a square foot, so a 100-square-foot area runs about $1,000 to $2,500 (July 9, 2026); HomeGuide at $15 to $30 (February 5, 2026). Small jobs cost more per foot because the setup, containment and disposal cost the same whether the patch is 5 square feet or 50, which is why Advanced Disaster Recovery's New Jersey price for an area under 10 square feet starts at $500.

The size also decides who should do the work. The NJ Department of Health's Mold Guidelines for New Jersey Residents draw the same lines as EPA's brief guide: under 10 square feet a homeowner may be capable of the work, between 10 and 100 square feet get a professional opinion, and above 100 square feet hire a qualified contractor with mold or environmental cleanup experience.

Measure before you call

  • 10 square feet is a patch about 3 feet by 3 feet (EPA). Two such patches on one wall is still under 100.
  • Count every surface: the wall, the back of the paneling, the underside of the subfloor. EPA lists the back of drywall, wallpaper and paneling, carpet pads and ductwork among the places mold hides.
  • Photograph the area with a tape measure in the frame. It is the first thing a provider asks for and the fairest way to compare bids.
  • If the water came from sewage, the Department says extra steps are needed to assess, clean and decontaminate. That is not a do-it-yourself job at any size.

Attic, Basement, Crawl Space, Bathroom, HVAC: Cost by Where the Mold Is

Location moves the price because of access and what has to come out. Advanced Disaster Recovery prices a New Jersey attic at $2,500 to $12,000, a crawl space at $2,000 to $9,000 and HVAC mold cleaning at $1,200 to $7,500 (April 26, 2026). Nationally, Angi puts an attic at $1,000 to $4,000, rising to $7,000 after a large or long-undetected roof leak, and a basement at $500 to $3,000 (July 9, 2026), while HomeGuide splits partial and full jobs: $1,500 to $6,000 for part of an attic or basement and $6,000 to $15,000 for all of it (February 5, 2026).

The source of the water decides the second bill. Angi ties attic mold to roof leaks and says to repair the leak to prevent regrowth; if your attic mold sits over a stained ceiling, price the roof with the roof leak repair cost guide for New Jersey. Basement mold usually follows a leak, a backup or seepage; when water is still coming in, start with water damage restoration, because EPA says drying wet materials within 24 to 48 hours is what prevents mold in most cases.

Expect the rebuild on top. Angi prices drywall repair at $300 to $825, carpet at $775 to $2,600 and flooring repair at $200 to $550 (July 9, 2026); HomeGuide prices new drywall at $1.50 to $3.50 a square foot, paint at $1 to $3 and insulation at $1.00 to $4.50 (February 5, 2026).

Mold Inspection and Testing Cost in NJ, and When You Can Skip the Lab

Testing is the line people overspend on. The NJ Department of Health's guidelines say that if a visual inspection reveals mold, additional testing is not necessary, and that once a problem is found, resources would be better used to correct the moisture problem and clean up the mold than for testing. EPA agrees: in most cases, if visible mold growth is present, sampling is unnecessary, and there are no EPA or federal limits for mold to test against.

Testing earns its fee when you smell mold but cannot find it, after water damage behind finished walls, before buying a house, and after remediation to confirm the job. In New Jersey, Advanced Disaster Recovery prices a visual inspection at $200 to $500 and a full inspection with air samples at $400 to $1,000 (April 26, 2026); Advantage Mold Experts, which serves New Jersey, Pennsylvania and Delaware, starts a basic visit with limited samples at about $350 and comprehensive testing at $500 to $2,500 (March 12, 2026). Nationally, Angi's average inspection is $689, from 7,940 verified projects, with most between $303 and $1,075 (October 5, 2026).

How it is done: the Department says it starts with a thorough visual inspection, and any sampling follows a plan that says why each area is sampled. Typical samples are bulk (a piece of building material), surface, dust and air, and testing may also cover the relative humidity in the home and moisture readings of building materials. You should get a written report with what was inspected, the source of the water and how to fix it, the size and location of the growth, and the results.

Three testing rules from New Jersey’s own guidelines

  • Do not simply ask for mold testing. Ask for a plan to stop the water and a plan to remediate, and ask why any test is being done and what its report will tell you.
  • Consider a different company for testing than for remediation. The Department says using the same company may present a conflict of interest.
  • Agree before work starts on the levels the clearance test must meet. The Department's checklist calls for testing after remediation to confirm levels are back to normal.

What New Jersey Law Does and Doesn't Require (October 2026)

New Jersey does not license mold remediators. The NJ Department of Health's mold page says plainly that there are no State certification programs for companies performing mold or general indoor air and environmental health services, and that the lists of consultants, laboratories and remediation firms it publishes are not endorsements. Some New Jersey mold cost pages, and the AI summary Google showed for “mold remediation cost nj” on October 15, 2026, say New Jersey requires mold licenses. The Department's page and the Legislature's bill records say otherwise.

Three bills in the 2026 – 2027 session would change it. On njleg.state.nj.us on October 15, 2026, each shows only its introduction and committee referral; none has passed either house. The table below gives what each would do. Until one becomes law, nothing in New Jersey requires a mold license, a separate tester, or a mold inspection when a rental turns over.

What does apply is the rebuild. N.J.A.C. 13:45A-17.2 defines home improvement as repairing, restoring or demolishing residential property, including basements, insulation installation and wall-to-wall carpeting, which is what most remediation jobs tear out and put back. That work needs a Home Improvement Contractor registration with the Division of Consumer Affairs, a number that begins with 13VH. Check it on the State's license lookup, and see how to check a contractor in New Jersey for the full walk-through.

Selling or buying: New Jersey's Seller's Property Condition Disclosure Statement, N.J.A.C. 13:45A-29.1, asks in question 9a whether the seller knows of mold in the basement, crawl space or any other part of the structures, and in questions 9 and 10 about water, dampness and repairs to control it. When those answers show water, dampness or mold, the real estate licensee refers the buyer to the Department of Health's Mold Guidelines for New Jersey Residents.

What a New Jersey remediator can show you today

  • No State mold license or certification exists, so a number presented as one is not a State number.
  • A 13VH Home Improvement Contractor registration for the tear-out and rebuild, which the State lookup confirms.
  • Liability insurance that covers mold or microbial work, which the Department of Health says to ask about by name.
  • Specialized training for mold assessment work, which the Department's hiring tips tell you to ask about.
  • Lead or asbestos licenses, if it holds them. The Department notes a mold contractor may also be licensed for lead or asbestos work, and those licensing offices can tell you about work-practice violations.

S760 / A1607, the Mold Safe Housing ActMold inspection of one- and two-family rentals at each change in occupancy and every five years; multiple dwellings every five years under the Hotel and Multiple Dwelling Law; a tenant whose landlord does not fix a mold hazard after a written request can go to the Department of Community Affairs; a buyer can ask a licensed home inspector to check for mold.Both introduced January 13, 2026. S760 is in the Senate Community and Urban Affairs Committee; A1607 is in the Assembly Housing Committee.

S1219The Department of Community Affairs would set up certification programs for mold inspectors and mold hazard abatement workers in homes and schools. Owners working on their own property would be exempt.Introduced January 13, 2026; in the Senate Community and Urban Affairs Committee.

New Jersey Sales Tax on a Mold Remediation Bill

None of the national guides mention it, but it changes a New Jersey bill. The NJ Division of Taxation's sales and use tax FAQ (last updated April 24, 2025) answers it directly: charges for mold inspection or detection are not subject to sales tax; mold removal, such as spraying walls to treat mold, and mold remediation, such as treating and scrubbing a frame gutted to the studs, are repairing or servicing real property and are taxable at New Jersey's 6.625 percent rate.

The exception is a full rebuild. The same FAQ says removing and replacing all the walls and insulation because of mold is an exempt capital improvement, and the property owner documents it by giving the contractor a completed Certificate of Exempt Capital Improvement, Form ST-8. By arithmetic, every $1,000 of taxable remediation adds $66.25 of tax.

On the quote, look for three lines

  • Inspection or testing, with no sales tax charged on it.
  • Remediation (containment, removal, HEPA cleaning, treatment), with 6.625 percent tax.
  • Rebuild. If all the walls and insulation are being replaced, ask whether the job qualifies for Form ST-8; the FAQ says only the property owner issues it.

Does Homeowners Insurance Pay for Mold Remediation?

Usually not, unless a covered event caused it. Triple-I, the insurance industry's information institute, says mold, like rot and insect infestation, is a home maintenance issue that standard homeowners policies generally do not cover, but that if the growth is the direct result of a covered peril such as a burst pipe, the cost of eliminating it may be covered. Federal flood insurance may cover mold or mildew only when it is directly attributable to a flood. HomeGuide says the same: coverage generally follows a disaster or a plumbing accident that caused the water damage (February 5, 2026).

For attic mold, that usually means slow condensation or a roof leak that ran for months reads as maintenance, while water from a sudden burst pipe may not. The color does not change the claim: the CDC says it is not necessary to determine what type of mold is growing and that all molds should be treated the same for health risk and removal. Call the insurer before anything is torn out, keep photos and the plumber's or roofer's invoice that names the cause, and read the mold or fungi section of your own policy for its limit.

How Long Mold Remediation Takes, and Whether Mold Comes Back

Small job, one area

1 to 2 days for under 10 sq ft (Advanced Disaster Recovery, April 26, 2026). HomeGuide puts small to medium projects at 1 to 3 days (February 5, 2026).

Medium job

3 to 5 days for 10 to 100 sq ft (Advanced Disaster Recovery). Containment, removal of moldy porous material, HEPA cleaning and drying all happen before anything is rebuilt.

Attic, crawl space or a large area

5 to 10 days (Advanced Disaster Recovery); up to 7 days for large or severe growth (HomeGuide). Drywall or carpet replacement adds to that.

Clearance test

1 to 2 more days for lab results (Advanced Disaster Recovery). The NJ Department of Health's checklist calls for testing after remediation to confirm levels are back to normal.

Mold comes back when the water does. EPA: if you clean up the mold but don't fix the water problem, the mold problem will most likely come back. It is also impossible to remove every spore indoors; the spores will not grow if moisture is not present. EPA's target is indoor humidity below 60 percent, ideally 30 to 50, and drying anything wet within 24 to 48 hours. The NJ Department of Health puts it more bluntly: a building cannot be made mold free, so avoid any contractor who claims it.

Whether you can stay home depends on the size and location. HomeGuide says a small contained area can usually be treated while you stay in another part of the house, and that most companies recommend leaving for large or severe growth (February 5, 2026).

Can You Remediate Mold Yourself? The 10-Square-Foot Line

For a patch under about 10 square feet, usually yes. EPA says that in most cases you can handle an area that size yourself, and the NJ Department of Health says a homeowner may be capable of it. EPA's kit is gloves, goggles and an N-95 respirator, which it prices at about $12 to $25. It says bleach and other biocides are not recommended as a routine practice, and never to mix bleach with cleaners that contain ammonia, because the fumes are toxic.

Hand it off when the area is over 10 square feet, when the water was sewage, when the mold is in the heating or cooling ducts, or when someone in the house is at higher risk. The Department lists people with allergies or lung conditions such as asthma or emphysema, infants and the elderly, and says anyone who suspects health effects should see their physician.

If the quote is more than you can pay

  • Fix the water first. EPA: dry wet materials within 24 to 48 hours and stop the leak, or the mold returns whatever you spend on it.
  • Skip the lab bill when the mold is visible. The NJ Department of Health says resources would be better used to correct moisture problems and clean up than for testing.
  • Do the small patches yourself. Under about 10 sq ft, EPA and the Department say a homeowner can usually handle it with gloves, goggles and an N-95 respirator.
  • Ask the insurer before anything is torn out if a burst pipe or another sudden event caused it (Triple-I).
  • Get several written bids on the same scope, and ask each company to price the remediation and the rebuild separately so you can phase the rebuild.
  • Renters: put the leak in writing to the landlord and call the local building code office about the leak itself, as the Department advises.

Who Pays for Mold Remediation: Owner, Insurer, Landlord or Seller

You own the home

You do, unless a covered event such as a burst pipe caused the growth and the policy pays to eliminate it (Triple-I). Flood-caused mold needs flood insurance.

You rent

The NJ Department of Health says the lack of mold regulations leaves government offices little authority to cite owners over mold. Call the local building code office about the leak itself, consider legal advice, and read DCA's Truth in Renting guide on the landlord's duty to keep a rental habitable. S760 would add a Department of Community Affairs route; it has not passed.

You are selling

The disclosure statement asks about known mold (question 9a) and water or dampness (questions 9 and 10). The form itself says the seller must disclose known material defects even where the form does not ask.

You are buying

Who pays is a contract term. Advanced Disaster Recovery prices a real estate mold inspection in New Jersey at $350 to $900 (April 26, 2026); the remediation estimate from that inspection is what you negotiate with.

How to Read a Mold Remediation Quote and Avoid Overpaying

None of this needs a lab degree. It needs a measured area, a dated price range for that area, a written scope that every bidder prices the same way, and a contractor whose registration and insurance you have checked. The tables above give you the first two; the NJ Department of Health's checklist gives you the rest.

Labor is most of the bill: HomeGuide puts mold remediation labor at $75 to $120 an hour (February 5, 2026), for containment, removal of moldy material, HEPA cleaning and drying. A line you cannot match to one of those tasks is the one to ask about.

  • Make every company bid the same written scope. The NJ Department of Health says estimates can vary significantly and the estimate should list every service: sampling, design, replacement and repair of damage. Be wary of a price far below the others and get the plan in writing.
  • Ask for the plan to stop the water first. The Department's guidelines say the water source has to be fixed before mold can be completely remediated, and EPA says that if the water problem is not fixed the mold will most likely come back.
  • Use a different company to test than to remediate. The Department says using the same company may present a conflict of interest. S3275 would make that separation law; today it is advice.
  • Do not pay for a species test when you can see the mold. The Department and EPA both say testing is not needed when mold is visible, and the CDC says all molds should be treated the same for health risk and removal.
  • Walk away from a mold-free promise. The Department's guidelines say a building cannot be made mold free and to avoid any contractor who claims it.
  • Ask what the liability insurance covers. The Department says to confirm the contractor's policy covers mold or microbial work, not only general contracting.
  • Get the rebuild priced as its own line. Angi prices drywall repair at $300 to $825 and carpet at $775 to $2,600 on top of the remediation (July 9, 2026), and HomeGuide prices new drywall at $1.50 to $3.50 a square foot plus $1 to $3 to paint (February 5, 2026).
  • Check the 13VH number for the rebuild. New Jersey treats repairing, restoring and demolishing home interiors, insulation and basements as home improvement work, which needs a Home Improvement Contractor registration.
  • Price the clearance test before work starts. Advanced Disaster Recovery's New Jersey range is $250 to $700 (April 26, 2026), and the Department advises agreeing in advance on the levels that count as done.
  • Read the sales tax line. Remediation is taxable at 6.625 percent in New Jersey; a full tear-out and replacement of walls and insulation can be an exempt capital improvement if you give the contractor Form ST-8.

How LA Trusted Partners Fits Into a Mold Job

This page is research

LA Trusted publishes this cost guide so you can budget from published figures. It does not test, inspect, remediate, remove mold, repair moisture sources, or guarantee clearance, and it sets none of the prices above.

The request is consent-first

You describe where the mold is, when it started and whether a leak came first. Your contact information is shared with a matched independent provider only after you agree to the disclosure.

The provider owns the work

Inspection, scope, containment, cleanup, documentation, pricing and warranty come from the independent provider. LA Trusted's standards ask that a provider's business identity and service area be checkable, and that registration, licensing where applicable, insurance evidence and complaint history be checked before routing.

Compare Mold Remediation Quotes From Independent NJ Providers

Tell us who you are and where the property is, then note where the mold or odor is, roughly how big the area is, and whether a leak or water damage came first. We take it from there and an independent local mold remediation provider calls you back.

Coverage depends on the town. LA Trusted does not do the work itself and does not promise a response time, so the inspection, scope, pricing and warranty come from the provider who calls you. Ask whether testing, remediation, drying, rebuilding and warranty are included or separate.

Already have a quote? Check the area against the tables and bring the gap, if there is one, to the second provider. The mold remediation request page takes the same request.

Mold Remediation Cost in NJ: Frequently Asked Questions

How much does mold remediation cost in New Jersey?

New Jersey estimates run higher than the national guides. typicalprices.com's Newark and Edison estimator puts most jobs at $2,407 to $9,386 with a typical job near $4,753 (October 5, 2026). Advanced Disaster Recovery, a restoration company with New Jersey offices, prices a small area under 10 square feet at $500 to $3,500, 10 to 100 square feet at $2,500 to $8,000 and 100 to 300 square feet at $5,000 to $15,000 (April 26, 2026). Nationally, Angi's average is $2,368 and most jobs run $1,223 to $3,757 (July 9, 2026).

What is the average cost to get rid of mold?

Angi's national average is $2,368, with most projects between $1,223 and $3,757 (July 9, 2026). Servpro's cost page quotes the same $2,368 average from HomeAdvisor data (September 14, 2026). HomeGuide puts the usual job at $1,500 to $6,000 (February 5, 2026). A whole house runs $10,000 to $30,000 (Angi) or $15,000 to $30,000 (HomeGuide).

How much does mold remediation cost per square foot?

Angi: $10 to $25 per square foot, so a 100-square-foot area runs about $1,000 to $2,500 (July 9, 2026). HomeGuide: $15 to $30 per square foot (February 5, 2026). Small jobs cost more per foot because of the setup: Advanced Disaster Recovery's New Jersey price for an area under 10 square feet starts at $500 (April 26, 2026).

How much does it cost to remove black mold from an attic?

Attic remediation runs $2,500 to $12,000 in New Jersey, average $6,000 (Advanced Disaster Recovery, April 26, 2026), against $1,000 to $4,000 nationally, or up to $7,000 after a large or long-undetected roof leak (Angi, July 9, 2026), and $6,000 to $15,000 for a full attic (HomeGuide, February 5, 2026). The color does not change the method: the CDC says it is not necessary to know what type of mold you have and all molds should be treated the same for health risk and removal. HomeGuide lists black mold jobs at $2,000 to $10,000, saying remediation may cost more when technicians must use additional chemicals, specialized equipment or several treatment methods.

How much does basement mold remediation cost?

HomeGuide prices part of a basement at $1,500 to $6,000, a whole basement up to $15,000, and one corner at $500 minimum (February 5, 2026). Angi's national range is $500 to $3,000, higher behind wood paneling or finished walls (July 9, 2026). No New Jersey source on this page prices basements separately; use the area rows: $2,500 to $8,000 for 10 to 100 square feet in New Jersey (Advanced Disaster Recovery, April 26, 2026).

Is it worth doing a mold inspection?

When you cannot see the mold but smell it, or after water damage, yes. When you can see it, the NJ Department of Health says additional testing is not necessary and resources would be better used fixing the moisture and cleaning up; EPA says the same. A visual inspection costs $200 to $500 in New Jersey and a full inspection with air samples $400 to $1,000 (Advanced Disaster Recovery, April 26, 2026); nationally the average inspection is $689 (Angi, October 5, 2026). Inspection is also the one part of the job New Jersey does not charge sales tax on.

How is mold testing done?

The NJ Department of Health says it starts with a thorough visual inspection, and a sampling plan should say why each area is sampled. Typical samples are bulk (a piece of building material), surface, dust and air; testing may also cover the relative humidity in the home and moisture readings of building materials. The report should cover what was inspected, the water source and how to fix it, the size and location of the growth, and the results. Angi prices a swab test at $200 to $300 and an air test at $250 to $350, up to $700 (October 5, 2026).

Does New Jersey require a license for mold remediation?

No. The NJ Department of Health states there are no State certification programs for companies performing mold or general indoor air services, and that the lists of firms it publishes are not endorsements. Three bills would change that, and none has passed: S3275 and A4952 (registration with the Division of Consumer Affairs) and S1219 (certification by the Department of Community Affairs) were introduced in 2026 and are in committee as of October 15, 2026. The rebuilding part of a job (drywall, insulation, flooring) is home improvement work that needs a Home Improvement Contractor registration.

Will homeowners insurance pay for black mold removal?

Only when a covered event caused it. Triple-I says mold is treated like rot and insect damage, as a maintenance issue that standard homeowners policies generally do not cover, but if the growth is the direct result of a covered peril such as a burst pipe, the cost of eliminating it may be covered. Federal flood insurance may cover mold only if it is directly attributable to a flood. The color of the mold does not matter to the policy; the cause does.

Does homeowners insurance cover mold in the attic?

Usually not when it comes from slow condensation or a long-running leak, which insurers treat as maintenance (Triple-I). If a sudden covered event, such as a burst pipe, caused the water that grew the mold, the cost of eliminating it may be covered. Read the mold or fungi section and its limit in your own policy, and call the insurer before the attic is torn out.

How long does mold remediation take?

Advanced Disaster Recovery's New Jersey timeline is 1 to 2 days for under 10 square feet, 3 to 5 days for a medium job, 5 to 10 days for a large attic or crawl space, and 1 to 2 more days for clearance lab results (April 26, 2026). HomeGuide says 1 to 3 days for small to medium jobs and up to 7 days for large ones, longer if drywall or carpet is replaced (February 5, 2026).

Can mold grow back after remediation?

Yes, if the water is not fixed. EPA: if you clean up the mold but do not fix the water problem, the mold problem will most likely come back. The NJ Department of Health adds that a building cannot be made mold free, so a contractor who promises that is overselling. Remediation lasts as long as the moisture stays under control; EPA's target is indoor humidity below 60 percent, ideally 30 to 50 percent.

Can I remediate mold myself?

For a patch under about 10 square feet, usually yes. EPA says most homeowners can handle an area that small, and the NJ Department of Health says a homeowner may be capable of the work; between 10 and 100 square feet get a professional opinion, and above 100 hire a qualified contractor. EPA lists gloves, goggles and an N-95 respirator, says bleach is not recommended as a routine practice, and warns never to mix bleach with ammonia. Mold from sewage water needs extra decontamination steps, per the Department.

What can I do if I can't afford mold remediation?

Stop the water first, because remediation without it is wasted. Skip testing when the mold is visible, as the NJ Department of Health advises. Clean small patches under 10 square feet yourself with the EPA precautions. Ask the insurer whether a sudden covered event caused it. Get several written bids for the same scope with the rebuild priced separately so you can phase it. Renters should put the problem in writing to the landlord and call the local building code office about the leak.

Who pays for mold remediation in a New Jersey rental or home sale?

In an owner-occupied home, the owner, unless insurance pays because a covered event caused it. For renters, the NJ Department of Health says the lack of mold regulations leaves government offices little authority to cite owners over mold; the local building code office can act on the leak, and legal advice can clarify your rights. In a sale, New Jersey's Seller's Property Condition Disclosure Statement asks the seller in question 9a whether they know of mold in the basement, crawl space or elsewhere, and the buyer is then referred to the Department's Mold Guidelines for New Jersey Residents. Who pays is a negotiating point in the contract.

Is Servpro expensive?

Servpro's own cost page does not publish Servpro prices. It quotes HomeAdvisor's national data, $1,223 to $3,753 with a $2,368 average, and tells readers to request a consultation (September 14, 2026). Like any company, its quote depends on the area, the materials and the scope; compare it on the same written scope as every other bid.

Is mold remediation taxable in New Jersey?

Yes, the remediation is. The NJ Division of Taxation's FAQ says mold removal and mold remediation are repairing or servicing real property and subject to the 6.625 percent sales tax, while mold inspection or detection is not taxable. Removing and replacing all the walls and insulation because of mold is an exempt capital improvement if the owner gives the contractor a completed Form ST-8 (FAQ last updated April 24, 2025).
