We noticed our laminate floor near the kitchen had started to cup and figured it was just age. The subfloor underneath was actually damaged from a slow leak. They pulled up the affected section, dried it properly, and matched the new flooring well.

Our insurance claim went smoothly because their photos and paperwork were thorough. Honest people who did what they said they would do.

Our home inspection flagged mold. These folks remediated it and gave us the clearance letter we needed to close.

Good to know

Floor & Subfloor Mold Removal in Shelter Island, NY: common questions

How do I know if my floor has mold underneath?

Warping, cupping, soft or spongy spots, and a persistent musty smell near the floor are the main signs. Discoloration where flooring meets a wall or appliance is another clue worth checking.

Will you install new flooring after removal?

We handle removal, subfloor assessment, and drying, and can coordinate flooring replacement to match your existing material as closely as possible.

What flooring types are most at risk?

Laminate and vinyl plank tend to hide subfloor damage the longest since the surface looks fine until the base underneath has already softened. Tile and hardwood usually show warning signs a bit earlier.

Will my insurance cover floor & subfloor mold removal in Shelter Island?

It depends on the cause. When the mold follows a sudden, covered event, there is often coverage. We bill your carrier directly and document the loss so your Shelter Island claim moves.

Can the subfloor always be saved?

Not always. Plywood that's only been briefly damp can often be dried and reused. Particleboard subfloor that's absorbed water usually swells and loses strength, and typically needs replacement.

Is this an emergency if the leak has stopped?

It's less urgent than an active leak, but the affected area should still be checked reasonably soon, since trapped moisture under flooring can continue causing damage even after the original leak is fixed.

How do you keep the mold from coming back after floor & subfloor mold removal?

We fix the moisture source first, not just the mold, then dry the structure and recheck it. That is what keeps mold from returning to a Shelter Island home.

Do you serve Shelter Island?

Yes. We cover all of Shelter Island, including Shelter Island Heights, Greenport, Greenport West, and the rest of the Shelter Island area. We are based in Sag Harbor, about 10 minutes from our Sag Harbor base, and answer our own phone around the clock.
