Mold help in Portsmouth
Coastal humidity and old stone foundations make basement mold common in Portsmouth, especially in homes near the water.
We remove mold from homes and businesses across Portsmouth, including the South End, the West End, Christian Shore, Pease and downtown around Market Square.
Portsmouth has many historic homes and downtown commercial buildings near the Piscataqua River, and coastal storms bring wind-driven rain and roof leaks. Older plaster, wood floors and fieldstone foundations need careful, documented drying.

Our mold remediation process
Remediation follows the IICRC S520 standard: inspection, containment, removal of damaged materials, HEPA cleaning and air filtration, then drying. We show you what caused the growth, whether that is a leak, poor ventilation or a damp foundation, and what needs to change so it stays gone.

Anytime I called or texted, I got a response almost immediately…even at off hours. They were all so nice, personable, caring, understanding, professional, and knowledgeable. I would give this company 20 stars if I could!”
