The insulation market in Exeter, NH, and the surrounding Seacoast region is characterized by high-quality, specialized contractors rather than a high volume of competition. Due to the age of many homes in New England, there is strong demand for energy efficiency upgrades, including attic air sealing and insulation, basement insulation, and blown-in wall insulation for older properties. The market is not saturated with low-cost, low-quality operators; instead, it is dominated by a few established, professional companies that hold advanced certifications (like BPI) and are deeply knowledgeable about local building codes and available rebates from providers like Eversource and Unitil. Pricing is typically mid-to-high range, reflecting the quality of materials, expertise in air sealing, and the comprehensive nature of the services offered.

Get answers to common questions about insulation services in Exeter, New Hampshire.
For Exeter's cold New Hampshire winters and humid summers, a combination of air sealing and high-performance insulation is critical. We prioritize air sealing the attic and basement rim joists to prevent drafts and moisture intrusion, followed by adding dense-pack cellulose or spray foam in walls and blown-in insulation in attics to achieve recommended R-values of R-49 for attics and R-15 to R-21 for walls. This approach directly combats high heating costs and improves summer comfort.
Costs vary significantly based on home size, insulation type, and accessibility, but Exeter homeowners can expect a typical attic insulation project to range from $1,500 to $4,500. Whole-house projects involving walls, basements, and attics can range from $5,000 to $15,000+. It's important to get a detailed, in-home assessment, as many local providers offer free estimates. Remember, New Hampshire's high energy costs mean quality insulation often pays for itself in heating bill savings within a few years.
While insulation can be installed year-round, the ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather in the Seacoast region, which is optimal for attic work and allows for proper ventilation during installation. Scheduling during these shoulder seasons also ensures your home is prepared before the peak heating season, and you'll find greater contractor availability than in the busy late summer rush.
Yes, Exeter residents have access to several key programs. The most significant is NHSaves, which offers rebates for air sealing and adding insulation when performed by a participating contractor. Additionally, New Hampshire has a 0% interest Heat Loan program for eligible energy efficiency upgrades. We always recommend checking with your insulation contractor about current incentives, as programs and amounts can change annually.
Always verify that the contractor is licensed and insured in New Hampshire. Look for companies experienced with Exeter's older home stock (like Colonial and Cape styles) and their specific challenges, such as knob-and-tube wiring or stone foundations. Choose a provider that conducts a thorough energy audit or assessment first, is a participating NHSaves contractor to access rebates, and provides clear details on the proposed materials, R-values, and air sealing methods.
