Stop dealing with drafty, stuck windows that waste your money every month.
Hear from Our Customers
You know the feeling when you walk past that one window and feel the cold air seeping through. Or when your energy bill arrives and you wonder why you’re paying to heat the outdoors.
New windows change that immediately. You’ll notice the difference the first week – rooms that stay the temperature you set them, less noise from outside, and windows that actually open and close like they should.
The real payoff comes over time. Lower energy bills, month after month. No more fighting with painted-shut frames or dealing with condensation that won’t go away. Just windows that work the way windows should work.
Sullivan Contracting has been installing windows in Colchester and surrounding Connecticut towns for years. We understand how New England weather beats up windows and what it takes to install them properly.
You won’t find us cutting corners on flashing, insulation, or weatherproofing. We’ve seen too many callback jobs from contractors who rushed through installations.
Our team shows up when scheduled, cleans up completely, and stands behind every installation. Most of our work comes from referrals because we do the job right the first time.
First, we measure your existing windows and discuss your needs – energy efficiency, style preferences, and budget. No pressure, just straight information about what works best for your situation.
Once you’re ready to move forward, we order your custom-sized windows and schedule installation around your timeline. Most installations take one day per window, depending on the size and any structural issues we find.
On installation day, we protect your floors and furniture, remove old windows carefully, and install new ones with proper insulation and weatherproofing. We clean up completely – you shouldn’t know we were there except for your new windows.
After installation, we walk through everything with you, explain warranty coverage, and make sure you’re satisfied with how everything looks and operates.
Ready to get started?
Every window installation includes proper removal of old windows, professional installation with appropriate flashing and insulation, and complete cleanup. We handle permits when required and make sure everything meets local building codes.
You’ll get manufacturer warranties on the windows themselves, plus our labor warranty covering the installation work. We use quality caulking and weatherstripping that holds up to Connecticut’s temperature swings.
Most Colchester homes have standard window sizes, but we handle custom sizing for older homes with non-standard openings. If we find any structural issues during removal, we’ll discuss options before proceeding – no surprise charges after the fact.
