Get answers to common questions about insulation services in Greenville, New Hampshire.
For Greenville's cold New Hampshire winters and humid summers, a combination of air sealing and high-R-value insulation is critical. We prioritize air sealing the attic and basement rim joists to prevent drafts and moisture intrusion, then recommend blown-in cellulose or fiberglass for attics (aiming for R-49 to R-60) and spray foam or dense-pack cellulose for walls. This approach directly combats high heating costs and prevents ice dams, which are a common issue in our region.
While insulation can be installed year-round, the ideal times in Greenville are late spring and early fall. These periods typically offer mild, dry weather, which is optimal for projects like attic work. Winter installations are possible but may be complicated by snow cover and extreme cold, while mid-summer attic work can be uncomfortably hot for crews. Planning ahead for a fall installation ensures your home is sealed and efficient before the harsh winter sets in.
Yes, New Hampshire homeowners have excellent incentive programs. The primary source is NHSaves, which offers rebates for air sealing and adding insulation that meet specific performance levels. Additionally, Greenville residents may qualify for federal tax credits for certain insulation materials. A reputable local installer will be fully versed in these programs and can often handle the paperwork, significantly reducing your net project cost.
Always verify the contractor is licensed and insured to work in New Hampshire. Look for companies with specific experience in our climate and ask for local references. They should conduct a thorough energy audit or assessment before quoting and should be able to clearly explain how their recommended solutions (like addressing air leaks before adding insulation) will perform in Greenville's conditions. Membership in local building associations is a good sign of community commitment.
For existing walls in historic or older Greenville homes, dense-pack cellulose or fiberglass insulation is the standard, effective solution. This involves drilling small holes in the exterior siding or interior walls, blowing insulation into the cavity to fill it completely, and then patching the holes. This method minimizes disruption, preserves your home's character, and provides a continuous thermal barrier that dramatically improves comfort and reduces energy bills.
