Get answers to common questions about insulation services in Sullivan, New Hampshire.
For Sullivan's climate (Zone 6, with very cold winters), air sealing combined with dense-pack cellulose or spray foam in walls and high R-value blown-in insulation in attics is often most effective for older homes. These methods address both conductive heat loss and the air infiltration common in historic New England structures. The goal is to achieve recommended R-values of R-49 for attics and R-15 to R-21 for walls to combat our long heating season.
Yes, New Hampshire homeowners can access significant incentives through the NHSaves program, which is funded by utility companies. These rebates are based on the amount of insulation installed and the resulting energy savings. Additionally, Sullivan residents should check with the Sullivan Town Office or Cheshire County for any local energy efficiency initiatives, and always consult a tax professional about potential federal tax credits for insulation.
The best times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather which is crucial for certain insulation materials to cure properly and for contractors to effectively assess and seal air leaks. Scheduling during these shoulder seasons also avoids the peak summer and winter rush, ensuring better availability from local contractors.
Prioritize contractors who are licensed and insured in New Hampshire and have specific experience with homes in our region. Ask for local references in Sullivan or nearby towns like Keene or Gilsum, and verify they perform a pre-installation energy audit. A reputable provider will understand local building codes, the challenges of New England home construction, and the NHSaves program paperwork.
Insulation is a critical part of the solution, but air sealing is the essential first step, especially in the attic. Ice dams are primarily caused by heat escaping from the living space, melting snow on the roof, which then refreezes at the eaves. A comprehensive approach for Sullivan homes involves sealing air leaks from the conditioned space into the attic, then adding adequate ventilation and high R-value insulation to keep the roof deck cold and prevent snow melt.
