Get answers to common questions about insulation services in Marlborough, Connecticut.
Given Marlborough's humid continental climate with cold winters and warm, humid summers, a balanced approach is key. Attic insulation (typically blown-in cellulose or fiberglass) is the top priority to prevent heat loss in winter and heat gain in summer. Additionally, properly insulating basement rim joists and crawl spaces is crucial to combat cold floors and moisture issues common in our region. For older homes, air sealing before insulating is especially important to address drafts.
Insulation can be installed year-round, but the ideal times are late spring and early fall. These periods offer mild temperatures, allowing for proper attic ventilation during installation and avoiding the extreme heat of a summer attic or the deep cold of winter. Furthermore, scheduling during these shoulder seasons ensures your home is fully prepared for the more demanding heating and cooling seasons, and contractors' schedules may be more flexible than in peak summer or winter.
Yes, Connecticut homeowners have excellent access to incentives through the EnergizeCT program, which is available to Eversource and UI customers in Marlborough. These include rebates for air sealing and adding insulation that meet specific performance standards. Additionally, you may qualify for federal tax credits for certain insulation materials. A reputable local insulation contractor will be familiar with these programs and can often help guide you through the application process.
First, verify the contractor is licensed and insured in Connecticut. Look for established local companies with strong references in Hartford or Middlesex County, as they will understand regional building practices and climate challenges. Crucially, choose a provider that performs a comprehensive energy audit or assessment before quoting, as this identifies specific air leaks and deficiencies rather than just selling a generic amount of material. Membership in organizations like the Building Performance Institute (BPI) is a strong indicator of expertise.
Not necessarily. While wall insulation is beneficial, the primary issue in many older New England homes is uncontrolled air leakage. In Marlborough, addressing "the building envelope" through professional air sealing of gaps, cracks, and bypasses in the attic, basement, and around windows/doors is often the most cost-effective first step. After air sealing, adding insulation becomes far more effective. A whole-home energy assessment is the best way to diagnose the specific sequence of improvements for your house.
