Your old windows are costing you money every month. Drafts, condensation, and poor insulation mean your heating and cooling systems work overtime just to keep you comfortable.
New windows change everything. You’ll notice the difference immediately – rooms stay the temperature you set them, outside noise drops significantly, and those annoying drafts disappear completely.
The real payoff shows up in your energy bills. Most homeowners see 15-25% reductions in heating and cooling costs within the first year. That’s money back in your pocket, month after month, while your home becomes genuinely more comfortable to live in.
Sullivan Contracting has been installing windows in southeastern Connecticut for years. We understand what works in this climate and what doesn’t.
Connecticut weather is tough on windows. From humid summers to freezing winters, your windows need to perform year-round. We’ve seen every type of installation challenge this area presents, from older homes with unique measurements to modern builds requiring precise specifications.
Our approach is straightforward – quality materials, proper installation techniques, and honest communication throughout the process. No surprises, no shortcuts, no excuses.
We start with accurate measurements at your home. Every opening gets measured twice because precision matters when you’re investing in new windows.
Once we’ve confirmed specifications and you’ve approved materials, we schedule installation around your timeline. Most residential window installations take one to two days, depending on the number of windows and any unique requirements your home presents.
Installation day means careful removal of old windows, proper preparation of openings, and precise installation of your new windows. We clean up completely before we leave, and we walk through everything with you to ensure you’re satisfied with the work.

Every window installation includes proper insulation, weatherproofing, and interior/exterior trim work. We don’t consider a job complete until everything looks and functions exactly as it should.
You’ll receive manufacturer warranties on all materials plus our installation warranty. This covers both the windows themselves and our workmanship, giving you complete protection on your investment.
We handle all the details – from permits if needed to cleanup afterward. Your job is to enjoy better comfort and lower energy bills. Our job is to make sure everything else happens smoothly and professionally.
