Get answers to common questions about insulation services in Plaistow, New Hampshire.
For Plaistow's cold New Hampshire winters and humid summers, air sealing and attic insulation are the most critical. Properly air sealing gaps and adding sufficient attic insulation (typically to R-49 or higher) prevents warm air from escaping in winter and stops humid summer air from causing condensation issues in your structure. This addresses the root cause of high heating bills and improves year-round comfort.
While Plaistow itself doesn't have unique insulation bylaws, New Hampshire state building codes require specific R-values for different parts of the home. More importantly, New Hampshire homeowners can access significant rebates and incentives through programs like NHSaves, which offer direct cash rebates for adding insulation and air sealing, making projects much more affordable. Your local contractor should be well-versed in these programs.
The ideal time is late summer through early fall (August to October). This allows the project to be completed before the harsh winter sets in, so your home is sealed and efficient for the heating season. Scheduling during this period also avoids the peak contractor demand of mid-winter and ensures attic spaces are at a safer, more moderate temperature for installers to work effectively.
Look for a contractor licensed in New Hampshire with strong local references in Rockingham County. They should perform a thorough energy audit or assessment using tools like a blower door test to identify your home's specific needs rather than offering a one-size-fits-all solution. Ensure they are familiar with and can facilitate the NHSaves rebate process for you.
Yes, this requires professional evaluation. Many older homes in the region have vermiculite insulation, which may contain asbestos. A qualified local professional should test it before any disturbance. For rock wool, while not hazardous, it often settles and loses effectiveness over decades, and modern materials like dense-pack cellulose or spray foam offer far superior air sealing and R-value for our climate.
