Get answers to common questions about insulation services in Manchester, New Hampshire.
The ideal time is late spring through early fall (May to September). During these months, Manchester's weather is milder, allowing for proper attic ventilation during installation and ensuring materials like spray foam cure correctly. Scheduling during this off-peak heating season also often provides better availability from local contractors compared to the urgent rush in late autumn.
Manchester's cold, humid continental climate, with winter temperatures often below freezing, demands high R-values, especially in attics. We recommend attic insulation levels of R-49 to R-60 to meet modern energy codes and combat significant heat loss. Using moisture-resistant materials like closed-cell spray foam in basements or crawl spaces is also crucial to prevent mold growth due to our region's humidity.
Yes, New Hampshire homeowners should first explore the "Home Energy Assistance" programs through NHSaves, which offers rebates for insulation improvements that meet specific performance standards. Additionally, Eversource and Liberty Utilities in the Manchester area provide direct incentives and energy assessments. It's also wise to check if any local Manchester-based energy efficiency grants are currently available through city programs.
Prioritize contractors who are licensed in New Hampshire and carry proper insurance, including workers' compensation. Look for established local companies with specific experience in handling Greater Manchester's older home stock, which often has unique challenges like knob-and-tube wiring or stone foundations. Always ask for local references and verify they follow the International Energy Conservation Code (IECC) standards adopted by New Hampshire.
For a typical 1,500 sq ft attic in a Manchester colonial, blown-in cellulose or fiberglass insulation to achieve R-49 can range from $1,500 to $3,500. Key cost factors include the current insulation condition (e.g., needing removal of old material), attic accessibility, the chosen material (with spray foam being more expensive), and the necessity for air sealing, which is critical for energy efficiency in our windy climate. Always get itemized estimates from multiple local providers.
