What Makes Portsmouth, New Hampshire Different
Portsmouth is one of the oldest cities in the country, and many homes on the Seacoast are well over a century old. Granite and brick foundations seep in wet seasons, old roofs leak around chimneys, and lead paint is common in homes built before 1978. Old plaster, pipe wrap and floor tile may contain asbestos, so test before you tear anything out.
Winters bring nor’easters, heavy wet snow and many freeze and thaw cycles. Ice dams form along the eaves of older homes with little attic insulation, and meltwater backs up under the shingles into ceilings and walls. Pipes in exterior walls and unheated spaces freeze and split, and the leak usually shows up when things warm up.
Coastal storms push high tides into low streets along the harbor, the Piscataqua and the beaches. Floodwater from outside is contaminated, and a standard homeowners policy does not cover it. Salt water corrodes wiring fast, so have an electrician check anything that was under water before the power goes back on.

Checking a License in Portsmouth and the Seacoast
New Hampshire does not license general contractors at the state level, though plumbers and electricians need state licenses. Maine is the same, with no statewide general contractor license but state licenses for plumbers and electricians. On either side of the river, check with your city or town building department about permits before rebuild work starts. Neither state has a separate mold license, so ask whether the technicians hold industry certification in water damage and mold remediation, and ask for proof of liability and workers compensation insurance. If the home was built before 1978, ask whether the crew is certified for lead safe renovation.
