What Is The Best Mold Inspection Company In NYC? 7 Best Reviewed

Search for the best mold inspection company in NYC and you’ll see the same things on repeat: “#1 in New York,” “same-day results,” “certified experts.” 

Big promises. Polished websites. Five-star reviews that all sound alike. 

Meanwhile, you’re trying to figure out who’s really licensed, who might oversell remediation, and whose report will hold up with a co-op board or insurance adjuster.

We’ve rounded up 7 of the most reviewed companies in NYC, where they’re genuinely strong, where they’re weaker, and how to decide which one makes sense for your building and timeline.

Top 3 Mold Inspection Companies in NYC

• Best for Commercial Buildings & Compliance-Heavy Jobs: South Bronx Restoration

• Best for Fast Testing with Clear Communication: The NYC Mold Experts

• Best for Strictly Independent, Inspection-Only Testing (No Remediation Upsell): RTK Environmental Group

1. South Bronx Restoration

Best For: Commercial properties and multi-unit buildings that need licensed, compliant mold inspection and remediation in NYC

South Bronx Restoration positions itself as a full-service restoration company, not just a mold testing outfit. That matters. If you’re managing a building, restaurant, or office and mold is tied to a leak or water event, you likely need inspection, testing, and certified remediation handled under one roof. They offer that continuity.

Their 5.0 rating is based on only nine reviews, so it’s a small sample size. Still, the feedback consistently highlights fast response times, straightforward communication, and no-pressure assessments. 

A recent review mentions a Harlem building inspection where the assessor clearly explained what was and wasn’t a real issue. That kind of clarity is valuable in NYC, where “mold scare” upsells are common.

Mold-Related Services

• Licensed mold inspection

• Mold testing (air and surface sampling)

• Black mold identification

• Contamination level measurement

• Certified mold abatement and remediation

• Action-ready reports for compliance and insurance

• 24/7 emergency response

Pros

• Licensed NYS mold assessors and abatement contractors

• Offers both mold inspection and remediation, reducing handoff delays

• 24/7 availability, useful for property managers

• Detailed reports suitable for insurance and compliance

• Strong reputation for fast emergency response

Cons

• Limited number of public reviews compared to larger NYC firms

Score: 4.8/5

2. The NYC Mold Experts

Best For: Homeowners and property managers who want fast lab results and full-service mold inspection in NYC

The NYC Mold Experts lean heavily into speed, and in New York, that makes sense. Waiting a week for mold testing results in NYC isn’t realistic when you’re dealing with tenants, co-op boards, or worried parents. Their promise of same-day or 24-hour lab results stands out, especially for time-sensitive situations.

Review feedback consistently mentions thorough inspections and clear communication. One homeowner noted they “checked every corner” and didn’t rush, while another appreciated detailed explanations about mold risks around a baby. 

That balance of speed and reassurance is important. Fast is good. Rushed is not. Based on reviews, they seem to understand the difference.

Mold-Related Services

• Mold inspection in NYC

• Air and surface mold testing in NYC

• Same-day lab analysis

• Mold removal

• Mold remediation

• Commercial mold testing

• Residential mold testing

Pros

• Same-day or 24-hour lab results, which is rare in NYC

• Licensed inspectors using infrared cameras and moisture meters

• Clear, upfront pricing mentioned in reviews

• Handles inspection, testing, and remediation in-house

• Strong emphasis on communication and transparency

Cons

• Strong focus on speed may not matter as much for non-urgent cases

Score: 4.7/5

3. ABC Environmental LLC

Best For: Property owners who need full compliance documentation and large-scale environmental testing in NYC

ABC Environmental LLC is not just a mold inspection company in NYC – they operate as a full environmental compliance firm covering mold, lead, and asbestos testing and remediation across the tri-state area. 

If your situation involves HPD violations, co-op requirements, or building permits, that broader capability matters.

With over 260 Google reviews and a 5.0 rating, they have significantly more public feedback than most firms on this list. Reviews consistently mention responsiveness, honest guidance, competitive pricing, and fast lab turnaround. Several clients highlight same-day inspections and next-day results. 

A recurring theme is paperwork handled correctly the first time, which in NYC can save weeks of back-and-forth with building management.

Mold-Related Services

• Mold inspection in NYC

• Air quality mold testing

• Surface mold testing

• Moisture and leak investigation

• Post-remediation clearance testing

• Real estate mold inspections

• Mold remediation

• 24/7 emergency mold response

Pros

• 260+ Google reviews with strong consistency in feedback

• Handles testing, remediation, and compliance documentation in-house

• Same-day inspections and 24 to 48-hour lab results frequently mentioned

• Transparent pricing and competitive quotes

• Experienced with co-ops, HPD, and permit requirements

Cons

• Heavy focus on lead and asbestos may dilute mold-specific specialization

• Owner-forward branding, which can mean experience varies by assigned team

• One public negative review among otherwise strong feedback

Score: 4.6/5

4 RTK Environmental Group

Best For: Unbiased, independent mold testing in NYC with no remediation conflict of interest

RTK Environmental Group has been around for 30 years and has completed over 40,000 inspections across the tri-state area. 

What makes them different from many mold inspection companies in NYC is simple: they do testing only. No remediation. No cleanup. No abatement crews. That structure eliminates the classic conflict of interest where the same company that finds mold also profits from removing it. 

For homeowners who want strictly objective mold testing in NYC before deciding on next steps, that independence is a major advantage. Reviews are mixed online in volume, but the company’s positioning as a testing-only firm is clear and consistent.

Mold-Related Services

• Mold inspection in NYC

• Air quality testing

• Black mold detection

• Mold abatement pre-testing

• Post-remediation testing

• Indoor air quality testing

• VOC testing

Pros

• 30 years in business with 40,000+ inspections completed

• No remediation services, which removes financial bias

• Independent lab testing

• Clear written reports with recommended next steps

• Fast verbal results, often within 24 hours

Cons

• Does not perform remediation, so you’ll need a separate contractor

• Smaller local review footprint compared to some competitors

Score: 4.4/5

5. Fast Mold Testing - New York

Best For: Fast, remediation-free mold testing in NYC when you need answers for a move, a landlord, or a closing

Fast Mold Testing is built for urgency. Not “panic and oversell” urgency. Real NYC urgency. The kind where you’ve got a lease starting, family coming to stay, a buyer asking questions, or you’re trying to work out if that smell is nothing or a real moisture problem.

What makes them different is the testing-only model (no remediation), plus a process that is designed to move fast. They combine on-site inspection and sampling with lab-backed results, then wrap it into a report that’s meant to be used. 

The reviews back that up – people mention same-day availability, inspectors showing up with the right tools, and being walked through results in plain language instead of being handed a confusing PDF.

Mold-Related Services

• Mold inspection in NYC (residential and commercial)

• Air quality mold testing (third-party lab analysis)

• Surface sampling (swab and tape-lift)

• Moisture mapping and humidity checks

• Infrared screening for hidden moisture

• ERMI mold testing

• Pre-move and real estate mold inspections

Pros

• Testing-only, so less incentive to push remediation

• Fast turnaround (report often within 48 hours, sometimes faster)

• Inspectors explain the process and results clearly

• Tools and sampling feel thorough based on reviewer specifics

• Strong fit for renters, landlords, and realtors who need documentation quickly

Cons

• Reviews are overwhelmingly positive and sometimes repetitive, so you’ll want to judge by the inspector experience you get

• The brand leans hard into “#1” claims and broad press badges, which doesn’t help trust

Score: 4.3/5

6. New York Mold Specialist

Best For: HPD violations, landlords and property managers who want a local, full-service team

New York Mold Specialist is family-owned, has a physical Brooklyn office you can walk into, and handles both inspections and remediation. For a lot of people, that “one team handles it” setup is exactly what you want, especially if you’re juggling an HPD mold violation, a tenant timeline, or water damage that is clearly not going to magically dry itself.

The reviews are heavy on specifics: inspectors showing up fast, being thorough, checking areas customers didn’t think about, and explaining what’s truly a problem versus what isn’t. Tal’s name comes up constantly, which usually means either strong owner involvement or a very owner-led operation. Either way, it reads like a business where communication is a real priority, not an afterthought once they’ve got the job.

The one tradeoff to keep in mind is the obvious one: because they remediate, there’s always a potential conflict of interest. That doesn’t mean they’re doing anything shady, just that you should ask good questions, get clarity on scope, and make sure sampling and reporting are documented properly before you approve remediation work.

Mold-Related Services

• Mold inspection (NYC, Long Island, Tri-State)

• Mold testing and assessment (air analysis and sampling referenced in reviews)

• Mold removal and mold remediation

• Post-remediation clearance testing (mentioned in reviews)

• Mold violation support (HPD mold violation help is specifically referenced)

• Water damage, flood damage cleanup tied to mold issues

Pros

• Strong review volume (around 323 reviews) and very recent activity

• Clear “walk you through it” communication style comes up repeatedly

• Full-service capability is helpful when inspection turns into “we need this fixed now”

• Appears used often for HPD violation workflows and building-level issues

Cons

• Inspection + remediation under one roof can create a conflict-of-interest dynamic

• Owner (Tal) is central in reviews, so experience may vary if another tech is assigned

Score: 4.2/5

7. 111 Home Inspections NYC

Best For: Condo and co-op buyers who want a meticulous, unbiased inspector

111 Home Inspections NYC feels like hiring a hyper-detail-oriented specialist. Edmond (the owner and lead inspector) gets called out again and again in reviews for being thorough to the point of obsession in a good way. People mention him catching issues others miss, explaining what he sees, and patiently following up when buyers have questions after the report lands.

The big differentiator is how “buyer-friendly” the experience is. You get next-day reporting, loads of photos and detail, and a calm, methodical walkthrough that helps first-time buyers feel in control. 

If you are trying to avoid nasty surprises at closing, this is the kind of inspector people seem to trust.

Mold-Related Services

• Mold inspection and mold sampling

• Thermal imaging inspection (moisture detection support)

• Moisture meter and humidity monitoring (as part of inspection workflow)

• Indoor air quality related checks (when mold is suspected)

Pros

• Extremely thorough inspections, frequently described as above-and-beyond

• Next-day detailed reports with clear explanations and visuals

• Strong communication and responsiveness before and after inspection

• Advanced tools (thermal imaging, moisture detection, drone as needed)

• Great fit for NYC condos and co-ops where hidden issues are common

Cons

• Focus is inspection and assessment, not a bundled remediation solution

Rating: 4.1/5

Comparison: Best Mold Inspection Company in NYC

How To Choose A Mold Inspection Company in NYC

New York is not forgiving when it comes to mold. 

Between Local Law 55, HPD violations, co-op board requirements, and insurance claims, choosing the wrong company can cost you time, money, and credibility. 

Here’s what matters:

1. Licensing and Certifications

In NYC, mold assessors must hold a New York State Mold Assessor license under Labor Law Article 32. Without it, the report may not stand up for insurance, legal disputes, or building compliance.

Every company in this list operates within the licensed framework. The difference comes down to how that licensing is applied.

• South Bronx Restoration stands out for pairing licensed assessment with licensed remediation under one coordinated structure. For commercial buildings or multi-unit properties, that continuity reduces delays and paperwork gaps.

• RTK Environmental Group emphasizes certified, independent testing backed by accredited labs, which appeals to clients focused purely on objective data.

If documentation is your priority, verify the license number and ask who signs the report.

2. Independence vs. Full-Service Capability

There are two legitimate models in NYC.

Testing-only firms eliminate remediation bias.

Full-service firms eliminate handoff delays.

Testing-Only Advantages:

• RTK Environmental Group

• Fast Mold Testing – New York

• 111 Home Inspections NYC

These are strong options if you want strictly objective results before deciding on cleanup.

Full-Service Advantages:

• South Bronx Restoration

• The NYC Mold Experts

• ABC Environmental LLC

• New York Mold Specialist

For HPD violations, commercial properties, or active water damage, full-service can be more practical. 

The key is not “which model is right.” It is asking clear scope questions before approving remediation.

3. Report Quality and Documentation

In NYC, vague mold reports are useless.

You want:

• Lab-backed results

• Moisture readings

• Clear photo documentation

• Defined next steps

Strong Reporting Reputation:

• 111 Home Inspections NYC is frequently praised for detailed, next-day reports with clear explanations.

• ABC Environmental LLC is repeatedly mentioned for compliance-ready paperwork.

• South Bronx Restoration is positioned well for insurance and building documentation tied to remediation workflows.

• The NYC Mold Experts balance fast turnaround with digestible reporting, which is useful for homeowners needing clarity quickly.

4. NYC-Specific Experience

Pre-war buildings, steam heat leaks, AC condensation lines, roof penetrations, and co-op board protocols are very specific to this market.

• South Bronx Restoration and ABC Environmental LLC show strength in multi-unit and compliance-heavy environments.

• The NYC Mold Experts and New York Mold Specialist appear frequently in residential and landlord scenarios.

• 111 Home Inspections NYC is particularly strong for condo and co-op buyers who want meticulous, buyer-focused assessment.

In NYC, experience is not about years alone. It is about understanding how mold issues intersect with building rules, tenant timelines, and legal documentation.

Final Tip

Get at least three quotes, confirm licensing numbers, ask whether they remediate, and request a sample report before booking. 

In NYC, documentation and independence often matter more than speed alone.

Frequently Asked Questions

How much does a mold inspection cost in NYC?

Most mold inspections in NYC range from $300 to $700 for a standard apartment, depending on sampling and lab analysis. Larger homes, commercial properties, or multiple samples can push costs higher. Always confirm what is included before booking.

How long does mold testing take in New York?

The on-site inspection usually takes 1 to 3 hours depending on property size. Lab results are typically available within 24 to 48 hours, though some companies offer same-day processing for urgent cases.

Is mold inspection required before selling or buying a property in NYC?

It is not legally required in most transactions, but many buyers request it during due diligence. In co-ops and multi-unit buildings, boards may require clearance documentation if mold is suspected.

What is the difference between mold inspection and mold testing?

A mold inspection is the visual and moisture-based assessment of the property. Mold testing involves collecting air or surface samples for lab analysis to confirm spore levels and species. Not every inspection requires testing, but testing adds documentation and clarity.
