Get answers to common questions about insulation services in Preston, Connecticut.
For Preston's cold Climate Zone 5, the U.S. Department of Energy recommends an attic insulation level of R-49 to R-60. This high R-Value is crucial to combat our harsh winters, retain heat efficiently, and reduce the strain on heating systems. Properly meeting this target can significantly lower annual heating bills, which is a major concern for local homeowners facing New England's energy costs.
Yes, Connecticut homeowners can access excellent incentives through the Energize CT program, which offers rebates for air sealing and adding insulation when performed by a participating contractor. Additionally, the state sales tax exemption on home energy improvements and potential federal tax credits make upgrades more affordable. It's essential to work with a provider registered in these programs to ensure you qualify.
The ideal times are late spring (May-June) and early fall (September-October) when temperatures are mild, allowing for proper installation and air sealing. Due to high demand ahead of winter, you should contact local contractors at least 4-6 weeks in advance. Scheduling in these shoulder seasons also ensures your home is prepared for the peak heating season, maximizing comfort and savings.
Always verify the contractor is licensed and insured in Connecticut. Look for specific experience with older homes common in our region, as they often have unique challenges like knob-and-tube wiring or plaster walls. Choose a provider that performs a comprehensive energy audit first and is a registered partner with Energize CT to ensure access to rebates and adherence to state performance standards.
Absolutely. For Connecticut's older housing stock, air sealing is the critical first step. Adding insulation on top of significant air leaks (common in attics, basements, and around windows) is far less effective. A professional assessment will identify leaks that let Preston's cold, damp air in, ensuring your new insulation performs optimally to improve comfort and energy efficiency year-round.
