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.

Great communication from the first call. They tested the air, handled the removal, and rechecked the space before signing off.

No more allergy symptoms since they cleaned the mold from our HVAC and bedroom walls.

Good to know

Crawl Space Mold Removal in Andover, MA: 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.

Do I need to leave my Andover home during the work?

Usually no. We seal the work area under negative air, so most of the Andover home stays livable. For larger jobs we will tell you if it is better to step out for a day.

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.

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 Andover home.

Do you serve Andover?

Yes. We cover all of Andover, including North Andover, Lawrence, Methuen, and the rest of the Andover area. We are based in Boxford, about 10 minutes from our Boxford base, and answer our own phone around the clock.
