Mold removal
Mold remediation in New Hampshire
Mold remediation removes mold growth under containment so spores don't spread, cleans or discards affected materials, and corrects the moisture problem that let it grow. Several states, including Texas, Florida, Louisiana and New York, license mold remediation, so check your state's rules.

Prolonged cold snaps freeze pipes in exterior walls, garages and crawlspaces. Vacation homes in the Lakes Region and White Mountains are at particular risk.
In Manchester: The converted Millyard buildings and older brick apartment blocks have thick masonry walls that hold moisture. Water damage there dries slowly and needs dehumidification sized for dense materials.
Old fieldstone foundations, oil heat and wood stoves are common. That means water seepage, puffback soot and chimney fire risks all show up in cleanup work here.
New Hampshire doesn't license general contractors statewide, though plumbers and electricians are licensed. Ask for insurance, references and a written contract.

Mold remediation questions
What should I do if pipes freeze in my New Hampshire home?
Shut off the main water, open faucets, and warm the area gradually with a space heater or hair dryer, never an open flame. If a pipe has split, call for extraction before thawing finishes.
Do New Hampshire restoration contractors need a license?
There's no statewide general contractor license, so check insurance, references and reviews, and get a written scope and contract.
Do I need a licensed company for mold removal?
It depends on your state. Texas, Florida, Louisiana and New York license mold remediation above set sizes. In other states, look for IICRC-certified remediators, insurance and a written scope.
Does bleach kill mold?
Bleach can whiten mold on hard, non-porous surfaces, but it doesn't penetrate drywall or wood and adds moisture. Removal and cleaning, plus fixing the moisture, is the reliable fix.
