Get answers to common questions about insulation services in New Boston, New Hampshire.
For our cold New Hampshire winters and humid summers, a layered approach is key. We highly recommend air sealing combined with attic insulation (typically blown-in cellulose or fiberglass to achieve at least R-49) and basement or crawlspace insulation to prevent cold floors. Properly insulating your home's envelope is critical for energy efficiency and comfort against New Boston's temperature extremes.
Costs vary significantly by home size, existing conditions, and materials, but for a standard 2,000 sq. ft. home, whole-house attic and wall insulation can range from $3,500 to $8,000. It's important to get a detailed, in-person assessment, as many older New Boston homes have unique construction that affects pricing. Remember, New Hampshire's high energy costs mean quality insulation often pays for itself in heating bill savings within a few years.
The ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is important for certain installations like spray foam, and they come before the peak heating season rush. Scheduling during these windows ensures contractors are more available and allows you to have your home sealed and ready before the harsh New England winter sets in.
Yes, New Hampshire homeowners have excellent incentives. The primary program is through NHSaves, which offers rebates for air sealing and adding insulation that meets specific performance standards. Additionally, New Boston residents should check with their local utility provider (like Eversource or Liberty Utilities) for direct rebates and with the Town Office for any local energy efficiency initiatives or property tax incentives.
Always verify they are licensed and insured in New Hampshire. Look for contractors experienced with the specific challenges of older New England homes, such as stone foundations or balloon framing common in the area. Choose a provider who conducts a thorough energy audit (often with a blower door test) first, provides a detailed written quote, and can clearly explain how their plan meets the recommended R-values for our climate zone (Zone 6).
