Contained removal
Mold Removal & Remediation in Portsmouth, NH
Growth and the material it grew into come out under containment, what remains is cleaned, and the assembly is dried and read before anything closes it in. The area is sealed and put under negative air, affected porous material comes out, and what remains is cleaned and treated. The assembly is then dried and read to the same standard as any water loss before it is closed, because remediation over a still-wet assembly puts the same growth back behind new drywall.
Independent local pros · containment before removal
Remediation here is the tail of a water job: growth is what an unfinished drying leaves behind, and removing it without finishing the drying puts it back. The contractor establishes how far the growth extends and what moisture is still feeding it, removes what grew, and dries and reads the assembly before it is closed. The service note below covers the sequence in this city.
Often needed alongside
- Mold Inspection & Testing
An independent assessor confirms whether the assembly that got wet is actually dry, whether growth started while it was not, and how far it reaches.
- Structural Drying & Dehumidification
Sealed air movers and dehumidifiers bring framing, subfloor and drywall back to a measured dry standard, with daily readings logged from inside the material.
Frequently asked questions
There is damp on every floor around the chimney. Is that three problems?
Almost certainly one. In a house framed around a central stack, water entering at the roof runs down the masonry itself rather than dropping into a ceiling, so it appears wherever the chimney passes a finished surface. The source is at the top and the marks below it are the path, not separate failures.
What is opened to dry it, given the age of the finishes?
As little as possible and as low as necessary. Base and casings around the stack come off first so the wall bottoms can breathe, and small openings are made where probe readings are high. Original plaster and trim are dried rather than removed wherever they are sound, which takes longer and is worth it here.
The stack is still damp in November. What does the winter do to it?
Wet masonry and a five-month freeze are a bad combination. Water held in a stack through repeated freezing takes the face off the brick and pushes the pointing out, so damage that was cosmetic in October is structural by April. The wettest month falls immediately before that, which is why autumn work is pushed hard.
