Mill conversions with mill-sized moisture problems
Mold, Water Damage & Painting in Dover, NH
Dover's brick mills along the Cocheco River have become apartments, offices, and storefronts. They are beautiful buildings — and they hold water in ways modern construction does not.
What we see in Dover buildings
Mill conversion is the signature Dover challenge. Heavy masonry absorbs and holds moisture, original timber framing sits inside it, and HVAC retrofits were designed for spaces that used to be full of machinery, not people. The result is humidity that lingers and odors that travel. Outside the mill district, Dover's early-1900s multi-families were largely balloon-framed, which gives moisture and smells an open path between floors and units — a leak reported on the third floor regularly turns up as a stain on the first.
What we do in Dover
Commercial & Multi-Unit Work
Mill buildings and multi-family properties, scheduled around tenants and businesses — including nights and weekends when a common area has to stay open during the day.

Masonry holds moisture long after the leak stops. We map it with meters and thermal imaging so remediation covers the actual affected area, not just the visible patch.

In balloon-framed multi-families water travels between units fast. Quick extraction and documented drying limits how many tenants are affected.

HEPA scrubbing and humidity documentation for converted spaces where ventilation was an afterthought.

Why do mill apartments hold humidity?
Brick and heavy timber absorb a lot of water and release it slowly, so a converted mill stays damp long after a leak is repaired. Ventilation is usually retrofitted rather than designed in, which means humid air has nowhere to go. Measured drying and dehumidification matter more in these buildings than in stick-framed construction.
A tenant reported mold. What happens first?
We find the water source before anything else, then contain and remediate. You get before-and-after air quality readings and a written record of what was done and when — which is what actually matters if the complaint escalates under New Hampshire's repair timelines.
Do you work around building tenants?
Yes. For occupied mill buildings and multi-family properties we schedule around business hours and tenant access, including evenings and weekends for common areas.
