01The mold clock
Had a leak? Here is what is happening inside your walls right now.
Drag the slider to when the water came in. The sooner we dry it, the less gets torn out and the smaller the bill.
24–48 hrsSpores wake up
Mold can start growing on damp materials within 24–48 hours. You won’t see anything yet, but wet drywall, cardboard backing and carpet pad are where it starts.
3–7 daysColonies form
Musty smell, small spots at baseboards, on the back of drywall and under carpet. Water keeps wicking upward inside the wall.
1–3 weeksSpreading inside the walls
Growth spreads through wall cavities, insulation and subfloors. Many jobs pass 10 sq ft here, which means New York’s mold law applies (independent assessor + licensed remediator).
1 month +Established mold
Structural materials are colonized. Paint and bleach won’t fix it; the affected material has to come out, the space has to be dried, then rebuilt.
Based on EPA guidance that mold can begin growing on damp materials within 24–48 hours. Actual timing depends on temperature, material and humidity.
02Field guide
Where mold hides in New York buildings
New York buildings are old, crowded and stacked on top of each other, and water travels between units. Tap a hotspot to see the eight places we find mold most often.
-
Flat roofs and parapets leak into the top-floor ceiling cavity. Stains show up months after the leak starts.
Attic & Roof-Leak Mold -
The #1 NYC call: a tub overflow, shower pan or toilet seal upstairs soaks your ceiling. Mold grows on top of the drywall where you can’t see it.
Bathroom Mold Removal -
Steam heat, single-pane windows and cold masonry mean condensation every winter, and black mold on the window returns.
Mold Behind Walls & Ceilings -
Shared supply and drain risers leak inside the wall between floors. First sign: bubbling paint or a musty smell near the bathroom or kitchen.
Mold Behind Walls & Ceilings -
Leaky steam valves drip for years behind radiator covers, rotting the floor and the wall behind it.
Mold Behind Walls & Ceilings -
Cold outside walls + no airflow + stored clothes = mold on the back wall of the closet and on whatever is stored there.
Black Mold Removal -
Slow drips from supply lines and dishwasher hoses rot the cabinet floor and the wall behind it.
Water Damage & Mold Prevention -
Groundwater, sewer backups in cloudbursts and boiler leaks. Finished basements hide it behind paneling and carpet.

04The honest process
We don’t test your mold. On purpose.
For jobs over 10 square feet, New York State requires three separate steps, and the company that tests can’t be the company that removes. Here is how it works:
-
Independent
1Licensed mold assessor
Inspects and tests, then writes the mold remediation plan: what has to be removed, how, and what counts as clean.
-
That’s us
2Licensed remediation contractor
Writes a work plan from the assessor’s plan, sets up containment, removes and cleans, dries, and treats the area.
-
Independent
3Post-remediation assessment
An independent assessor checks our work. Walls stay open until it passes. Then we rebuild.
Why we don’t test your mold: New York’s mold law (Labor Law Article 32) doesn’t let the same company assess and remediate the same project. A company that tests your home and then quotes you the removal has a conflict of interest. We only remediate, so our estimate is never inflated by our own test results.

Vinny and his crew did an excellent job. They responded quickly, arrived on time, and worked efficiently and professionally. The repair was done neatly, and they left everything clean when they finished. I really appreciated the fast response and quality work. I’m very happy with the service and would highly recommend Vinny!

Vinny a huge help! We had a stopped up drain with sewage coming up into the basement. He came within 3 hours (on a Saturday night), stayed and worked until it was all fixed and cleaned. He had a great attitude, was very trustworthy and saved the day.

FAQStraight answers
Questions people ask us
Do you offer free mold inspections?
We offer free on-site estimates for mold removal. We look at the damage, find the moisture source and give you a written price. We don’t do lab testing or formal mold assessments. Under New York law those are done by independent licensed assessors, which keeps the process honest.
How much does mold removal cost in NYC?
It depends on the size of the area, what materials are affected and how easy it is to get to. Small jobs cost far less than whole-unit work. See our NYC mold remediation cost guide for typical ranges and an instant estimate.
Are you licensed for mold remediation in New York?
Yes. We hold NYS Mold Remediation License #25-65KFU-SHMO, GC License #626382, and EPA Lead-Safe firm certification #NAT-F269558-1. We are fully insured.
Do you work with insurance?
Yes. We work with all insurance carriers and give you the photos, moisture readings and itemized scope your adjuster needs. Coverage depends on your policy and how the water got in; see mold & insurance.
Which areas do you serve?
All five boroughs: Brooklyn, Manhattan, Queens, the Bronx and Staten Island. We are based at 1138 Ocean Ave in Flatbush, Brooklyn and answer the phone 24 hours a day.
My landlord won’t fix the mold. Can you help?
If you rent, the building owner is responsible for fixing mold and the leak causing it under NYC Local Law 55. Our NYC mold law guide explains how to report it through 311. If you are a landlord or manager, we can do the work and give you the documentation.
