Get answers to common questions about insulation services in Glastonbury, Connecticut.
For our Connecticut climate with cold winters and humid summers, a combination of air sealing and attic insulation is most critical. We recommend achieving at least R-49 to R-60 in your attic with blown-in cellulose or fiberglass to retain heat in winter. Additionally, properly insulating and air sealing basement rim joists and crawl spaces is vital to prevent cold drafts and moisture issues common in our region.
Costs vary by home size and scope, but for a standard attic insulation project in a 1,500 sq ft Glastonbury home, homeowners can expect to invest between $1,500 and $3,500. Regional material and labor rates apply, and the final price depends on the existing insulation levels, the material chosen, and the complexity of the air sealing needed. Many local providers offer free, detailed assessments to give you a precise quote.
Yes, Connecticut homeowners have excellent incentives. The Energize CT program, sponsored by the state’s utilities like Eversource, offers rebates for adding insulation that meets specific performance standards. Additionally, the federal tax credits for energy efficiency improvements can apply. A qualified Glastonbury insulation contractor will be familiar with these programs and can help you complete the necessary energy audit to qualify.
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 Connecticut, which is optimal for the work and allows you to prepare your home before the peak heating season. Scheduling during these shoulder seasons also helps you avoid the busy winter rush for insulation contractors.
Always verify that the contractor is licensed and insured in Connecticut. Look for established local companies with strong reviews and specific experience with older homes common in Glastonbury. They should perform a thorough energy assessment, provide a detailed written estimate, and clearly explain how their work complies with the International Residential Code (IRC) standards adopted by Connecticut, particularly for vapor barriers and required R-values.
