We had a musty smell coming up through the kitchen floor for a while and finally had the crawl space checked. The vapor barrier had torn in a couple spots and mold had spread along several joists. They removed it and were careful around our radon system the whole time.

Good to know
Crawl Space Mold Removal in Shelter Island, NY: common questions
How do I know if my crawl space has mold?
The most common sign is a persistent musty smell in the rooms above, especially near the floor. Discoloration on exposed joists, if you can see into the crawl space, is another clear indicator.
Do you install vapor barriers?
We assess vapor barrier condition during inspection and can perform full crawl space encapsulation as a separate service if your space needs more than mold removal alone.
How long does crawl space mold removal take?
Most jobs run one to a few days depending on the size of the space and how much wood is affected. Low clearance can slow the physical work down even on a relatively small area.
How do you keep the mold from coming back after crawl space 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.
Is it safe to work in a crawl space with a radon system?
Yes, our crew works carefully around existing radon mitigation piping, sealing, and fan units. We won't disturb an active system, and we'll flag anything that looks compromised.
Can crawl space mold affect the air I breathe upstairs?
It can, since air moves between a crawl space and the living area above through gaps, ductwork, and flooring seams more than most people realize. That's part of why persistent odor complaints often trace back down there.
Do I need to leave my Shelter Island home during the work?
Usually no. We seal the work area under negative air, so most of the Shelter Island home stays livable. For larger jobs we will tell you if it is better to step out for a day.
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 Southold, about 10 minutes from our Southold base, and answer our own phone around the clock.
