Get answers to common questions about insulation services in Salem, New Hampshire.
For our climate, the best insulation often depends on the application, but spray foam and blown-in cellulose or fiberglass are top choices. Spray foam provides an excellent air seal, which is critical for combating New Hampshire's cold winds and humidity, while dense-packed cellulose is highly effective in existing walls. A professional assessment of your specific home is key, as many older Salem homes benefit from a combination of air sealing and insulation upgrades to meet modern energy standards.
For a standard 1,200 sq ft attic in Salem, adding blown-in cellulose or fiberglass to reach R-49 (recommended for our zone) typically costs between $1,500 and $3,000, with spray foam being significantly more. Salem homeowners should check for rebates from New Hampshire's "Core Residential" program through NHSaves, and also inquire with their local utility, Unitil, for potential incentives that can reduce the net cost by hundreds of dollars.
While insulation can be installed year-round, the best times in Salem are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is ideal for projects like attic work. Scheduling during these shoulder seasons also ensures your home is prepared before the peak heating season, and you'll have an easier time booking a reputable local contractor compared to the busy late summer rush.
Always verify the contractor is licensed and insured to work in New Hampshire. Look for companies experienced with Salem's mix of historic and newer homes, and ask if they perform a pre-installation energy audit. Check for membership in local associations like the BIA of NH and strong reviews on local platforms. Crucially, ensure they understand and follow NH's building codes for vapor barriers and ventilation to prevent moisture issues common in our climate.
Yes, properly addressing attic insulation and air sealing is the primary solution for preventing ice dams, a very common problem in Salem due to our heavy snowfall and temperature swings. Ice dams form when heat escapes from the living space, melts snow on the roof, which then refreezes at the colder eaves. By upgrading attic insulation to at least R-49 and meticulously sealing air leaks (like those around light fixtures and chimneys), you keep the roof deck cold and prevent the melt-freeze cycle.
