About
Planning projects in Connecticut
Connecticut's changing seasons and varied landscape create year-round demands on homes. Humid summers, cold winters, coastal storms, wooded neighborhoods, and aging housing stock all influence maintenance priorities. Homes near Long Island Sound face salt air and wind-driven rain, while inland communities often focus on snow, basement moisture, heating efficiency, and freeze-thaw cycles. Understanding how these conditions affect roofing, insulation, drainage, siding, windows, and foundations can help homeowners protect both comfort and long-term value.

Home improvement contractors must register with the Department of Consumer Protection (DCP) for contracts of $200 or more, including roofing, windows and remodels. Plumbing and HVAC are licensed by DCP's trade examining boards.
Rules vary by city and county. Confirm with your local building department.

Insurance requirements
All employers must carry workers' comp. The Home Improvement Guaranty Fund pays up to $25,000 per claim against a registered contractor.
Rules vary by city and county. Confirm with your local building department.
Permit rules
The statewide code was adopted in 2022, and local building officials issue permits. A 2024-based update is waiting on legislative approval. Contracts must be written and signed, with the registration number and dates, and homeowners get 3 business days to cancel.

Common questions about hiring a contractor
Start with their condition, operation, and the source of any drafts. If the frames and sashes are sound, repairs, weatherstripping, and properly fitted storm windows may improve comfort while preserving the existing windows. Replacement may be more appropriate where deterioration or operating problems are substantial. Ask for a comparison that includes installation, surrounding trim repairs, and expected maintenance—not just the price of the window units.
Investigate water entry and seasonal dampness before covering the foundation walls. Roof runoff, grading, groundwater, plumbing leaks, and condensation can require different solutions, so ask how the moisture source will be identified. The insulation design also needs to limit contact between humid indoor air and cold foundation surfaces. Resolve active water problems first, then coordinate insulation and moisture control so new finishes do not conceal unresolved conditions.
Use Connecticut’s eLicense system to check the contractor’s Home Improvement Contractor registration and confirm that it is active. Match the registered name to the person or business named in your contract; an individual’s registration does not automatically cover an LLC. Registration is one part of your review, so also check references and ask who will perform any work requiring a separate trade license. If the credential or business identity is unclear, contact the Department of Consumer Protection before signing.
