** The insulation market in New London, Connecticut, is characterized by a mix of local specialists and regional powerhouses that serve the broader Southeastern CT area. The competitive landscape is moderate, with a few highly-rated, established companies dominating the high-quality, energy-efficiency-focused segment. Due to New London's coastal location and older housing stock (including many historic homes), there is a significant demand for insulation upgrades, air sealing, and moisture control solutions. The average quality of service is high among the top-tier providers, who are typically well-versed in local building codes and incentive programs, such as those offered by the Connecticut Green Bank and Energize CT. These companies often use advanced diagnostic tools like blower door tests and thermal imaging to guide their work. Typical pricing is in line with New England averages. As a rough guide: * **Blown-in Attic Insulation:** $1,500 - $4,500 * **Spray Foam Insulation (closed-cell):** $1.00 - $1.50 per board foot * **Wall Insulation (blown-in):** $1,000 - $4,000 depending on wall size and access * **Energy Audit:** $400 - $800, often applied as a credit if work is performed. Customers are advised to seek multiple quotes and confirm that contractors are licensed and insured, and specifically inquire about their experience with the challenges of Southern New England's climate.

Get answers to common questions about insulation services in New London, Connecticut.
For many of New London's historic homes, blown-in cellulose or fiberglass insulation in attics and wall cavities is highly cost-effective. It provides excellent thermal resistance (R-value) for our cold Connecticut winters and helps manage summer humidity. Air sealing should be done first to maximize effectiveness, and you may qualify for rebates through the Energize Connecticut Home Energy Solutions program to offset costs.
Fall is typically the ideal time, as it allows you to prepare your home for winter heating while contractors' schedules are more open. However, insulation can be installed year-round. Avoid the peak of summer for extensive attic work due to extreme heat, and be mindful that winter installations may require special considerations for accessing certain areas if there's snow or ice.
Yes, all insulation work must comply with the Connecticut State Building Code, which adopts the International Residential Code (IRC) and sets minimum R-value requirements for different parts of the home. In New London, you may also need a building permit for major insulation retrofits, especially if it involves altering wall structures or adding insulation to previously uninsulated spaces. A reputable local contractor will handle this permitting process.
Look for licensed and insured contractors with strong local references, particularly for work on homes similar in age and style to yours. Verify they are a Participating Contractor with the Energize Connecticut program, as this ensures they meet specific standards. Always get 2-3 detailed written estimates that include the type of insulation, R-value, air sealing details, and a clear breakdown of labor and material costs.
Absolutely. New London's coastal climate with nor'easters makes drafts and heat loss common. Your attic is the primary area to inspect, as heat rises and escapes there first. Also, check basement rim joists, around windows and doors, and exterior walls. A professional energy audit, often available with incentives through Energize Connecticut, can use tools like blower door tests to pinpoint exactly where your home is losing energy.
