Comprehensive Services: Beyond mold and water remediation, we handle storm damage repairs, basement flood cleanup and fire restoration.

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Mold Testing and Remediation questions, answered by experts

In Long Island, NY, immediate action is needed if you see widespread mold, experience persistent musty odors, or have recent water damage. Mold in HVAC systems or visible growth over 10 square feet also requires prompt attention. Seasonal discoloration or minor surface spots can be monitored, but always schedule a professional mold inspection before selling your home or after major storms.

Helpful?

In Long Island, NY, be cautious of mold removal companies that lack detailed written estimates, skip a thorough mold inspection, or pressure you to commit on the spot. Watch for missing proof of insurance or unclear project timelines. If a contractor combines testing and remediation without independent verification, or avoids discussing the removal process and materials, consider it a warning sign.

Helpful?

For mold testing and remediation in Long Island, NY, use EPA-registered antimicrobial cleaners, HEPA-filtered vacuums, and air scrubbers sized for your space. Install moisture barriers like 6-mil plastic sheeting and opt for mold-resistant drywall or insulation in affected areas. Dehumidifiers designed for high-humidity environments and anti-microbial primers help prevent recurrence. Local suppliers in NY typically stock these specialized materials.

Helpful?

After mold testing and remediation in Long Island, NY, schedule a post-remediation mold inspection and air quality clearance test within 48 hours. Check for recurring moisture by monitoring humidity levels and inspecting for leaks monthly. Use humidity control devices, especially in basements. Keep all remediation and inspection records for future property transactions. Address any drainage or waterproofing issues to prevent new mold growth.

Helpful?

In Long Island, NY, small mold testing and remediation projects usually take 1–2 days, while moderate jobs may last 3–5 days. Larger or whole-home remediation can extend to several weeks, especially if humidity control measures or permit approvals are needed. Weather, property size, and the extent of water damage can also impact the overall timeline, so maintain regular communication with your contractor.
