Get answers to common questions about insulation services in Oneco, Connecticut.
For Oneco's cold winters and humid summers, a combination of air sealing and high-R-value insulation is critical. We recommend focusing on the attic first, using blown-in cellulose or fiberglass (R-49 to R-60), and ensuring basement rim joists and walls are properly sealed and insulated to prevent cold drafts and moisture issues common in our region. Properly insulating these areas directly combats our significant heating costs and improves summer comfort.
The best time for insulation work in Oneco is typically late spring through early fall, as attics can be extremely hot in summer and difficult to access in winter. However, professional installers work year-round. Completing the project before the peak heating season (October onward) allows you to lock in energy savings immediately, making the investment pay off faster during our long, cold winters.
Yes, Connecticut homeowners have excellent access to incentives through the Energize CT program, which is sponsored by the state's utilities like Eversource and UI. These include significant rebates for adding insulation and air sealing, and you may also qualify for 0% financing through the Home Energy Solutions (HES) assessment. Always verify your eligibility with your insulation contractor, as these programs have specific requirements.
Prioritize contractors who are licensed, insured, and have specific experience with New England homes. Look for companies that perform a thorough energy audit or assessment first, as this is often required for state incentives. It's also wise to choose a provider familiar with Oneco's older housing stock and the common moisture challenges in our area to ensure they recommend the right materials and methods.
Not entirely. In older Connecticut homes, air leakage is often the primary culprit for drafts and uneven temperatures. A comprehensive approach that combines air sealing (caulking, weatherstripping, and sealing bypasses) with adding new insulation is essential. This addresses both conductive heat loss (through walls) and convective heat loss (through drafts), providing the maximum improvement in comfort and energy efficiency for our climate.
