Get answers to common questions about insulation services in Danville, New Hampshire.
For Danville's cold winters and humid summers, the most impactful upgrades are typically air sealing and adding attic insulation to at least R-49. Basement rim joists and crawl spaces are also critical areas to insulate and air seal to prevent cold drafts and moisture issues common in our region. Properly addressing these areas significantly reduces heating costs and improves year-round comfort.
The best time for exterior projects like wall insulation is late spring through early fall to avoid winter weather. However, attic and interior work can often be done year-round. Scheduling during a contractor's traditional "off-season" (late fall or early winter) can sometimes yield better pricing or faster scheduling, but it's wise to book early as many Danville homeowners prepare for winter in the late summer.
Yes, the primary program is through NHSaves, which offers rebates for air sealing and adding insulation that meets specific performance levels. These rebates are administered through your local utility (like Eversource or Unitil) and can substantially reduce your upfront cost. It's crucial to use a participating NHSaves Registered Vendor to qualify, so always ask your contractor about this.
First, ensure they are licensed and insured in New Hampshire. Look for contractors who are NHSaves Registered Vendors, as this indicates specific training. Choose a company with extensive experience in our climate—they should perform a thorough energy audit or assessment and provide clear explanations about recommended R-values, air sealing, and moisture control strategies for your specific home type.
This is a valid concern for homes built before the 1980s, common in our area. Reputable local insulation contractors will inquire about your home's age and may recommend an inspection for asbestos in vermiculite or old pipe insulation before disturbing existing materials. Proper handling and disposal of any hazardous materials are regulated in NH and must be factored into the project plan and cost.
