Get answers to common questions about insulation services in Groton, Connecticut.
For Groton's historic homes, blown-in cellulose or fiberglass in attics and walls is often the most cost-effective retrofit solution, balancing performance with minimal disruption. Homeowners should explore incentives like the EnergizeCT Home Energy Solutions program, which offers assessments and rebates, and check with Groton Utilities for potential local rebates on insulation upgrades that improve efficiency.
Late summer and early fall are ideal for scheduling insulation work in Groton. This timing allows your home to be properly sealed and upgraded before the cold, damp coastal winter sets in, ensuring contractors are readily available and the work can be completed comfortably before heating season begins.
Yes, Groton's proximity to Long Island Sound means managing moisture is critical. Proper air sealing and vapor barriers are essential to prevent humid summer air from condensing inside walls, which can lead to mold. Insulation materials must be chosen and installed to resist moisture, with closed-cell spray foam often recommended for basement and crawlspace areas.
Always verify that a contractor is licensed and insured in Connecticut. Look for companies with specific experience in coastal New England homes and ask for references from local projects. A reputable provider will perform a thorough energy audit or assessment before quoting and should be knowledgeable about both the CT Building Energy Code and local utility rebate programs.
This is a common issue in Groton homes due to the region's strong winter winds. The problem is likely inadequate air sealing, not just insulation. Gaps around recessed lights, plumbing stacks, and attic hatches allow cold air to infiltrate. A professional assessment can identify these leaks; sealing them is often more impactful than simply adding more insulation.
