Get answers to common questions about insulation services in East Candia, New Hampshire.
Given East Candia's cold New Hampshire winters and humid summers, the top priorities are air sealing and adding attic insulation. Properly air sealing your attic floor and basement rim joists prevents warm, moist indoor air from escaping and causing ice dams or moisture issues in walls. We then recommend bringing attic insulation to at least R-49 (about 16-18 inches of blown cellulose or fiberglass) to meet the DOE's recommended zone for our climate, which dramatically reduces heat loss.
Costs vary by project scope, but for a standard 1,500 sq ft attic, blown-in cellulose insulation to achieve R-49 typically ranges from $1,800 to $3,200. It's important to get itemized quotes that include air sealing, as this is a critical step. New Hampshire homeowners should also inquire about available rebates from utilities like Liberty Utilities or the NHSaves program, which can offset 10-25% of project costs for qualifying insulation upgrades.
The ideal times are late spring (May-June) and early fall (September-October). These periods offer moderate temperatures, allowing for proper installation and curing of air-sealing materials like spray foam. While insulation can be installed year-round, scheduling during these shoulder seasons ensures better availability from local contractors and allows you to improve your home's envelope before the peak heating season hits.
First, verify they are licensed and insured to work in New Hampshire. Look for contractors experienced with our specific climate challenges, such as preventing ice dams and managing moisture. Ask if they perform a pre-installation energy assessment (many partner with NHSaves auditors) and provide detailed proposals that separate material, labor, and air sealing costs. Finally, check for strong local references and membership in organizations like the Building Performance Institute (BPI).
Yes, insulating walls in older homes is one of the most impactful upgrades for comfort and energy savings. For existing walls without insulation, the best method is typically dense-pack cellulose injection, performed by drilling small holes in the exterior siding or interior walls. This material fills cavities completely, provides a strong R-value (R-13 to R-15 for a 2x4 wall), and helps control the air movement and moisture that are common in New Hampshire's historic home structures.
