The insulation market in Hollis, NH, is characterized by high-quality, specialized contractors who primarily operate out of larger neighboring hubs like Nashua, Manchester, and Bedford. Due to Hollis's older housing stock and harsh New England winters, there is strong demand for energy efficiency upgrades. The competition is moderate but consists of established, professional companies rather than a high volume of smaller operators. Homeowners in Hollis are typically knowledgeable about energy savings and local utility rebates (e.g., from NH Saves), which drives demand for comprehensive services like air sealing and energy audits. Typical pricing is competitive with the broader New England region; a basic attic blow-in with cellulose can range from $1,500-$3,000, while full home air sealing and insulation projects or spray foam applications can range from $5,000 to $15,000+, depending on the home's size and scope of work.

Get answers to common questions about insulation services in Hollis, New Hampshire.
For Hollis's cold winters and humid summers, a two-pronged approach is key. First, air sealing and attic insulation (typically to R-49 or higher) are critical to prevent heat loss and ice dams. Second, insulating basement rim joists and crawl spaces helps manage ground moisture and drafts, which are common in our region. Properly addressing both temperature and moisture is essential for comfort and efficiency in Southern New Hampshire.
Costs vary significantly based on home size, insulation type, and areas treated. For a standard attic blow-in project, Hollis homeowners might expect a range of $1,500 to $3,500. Whole-house air sealing and insulation can range from $5,000 to $15,000+. It's important to note that New Hampshire has no sales tax on these services, and you should always get itemized estimates that include material (like cellulose or fiberglass) and labor.
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, making it easier for contractors to perform critical air sealing tests and for you to schedule before the busy winter rush. Avoid the deep winter if possible, as snow cover and extreme cold can complicate attic access and material handling.
Prioritize local contractors familiar with New Hampshire's building codes and Hollis's specific home styles (e.g., older colonials, modern builds). Verify they are licensed and insured in NH, and ask for proof of certification from manufacturers like Owens Corning or from building performance institutes (BPI). Always check local references and reviews to see their experience with similar projects in Hillsborough County.
Yes, the primary program is through NHSaves, which is funded by NH's utility companies (including Eversource and Liberty Utilities serving Hollis). They offer rebates for approved insulation and air sealing work that meets specific performance standards. Additionally, the federal Inflation Reduction Act provides tax credits for qualified energy efficiency upgrades. A reputable local contractor will be knowledgeable about these programs and can often help with the paperwork.
