Professional window installation that cuts your energy bills and eliminates those annoying drafts for good.
Hear from Our Customers
You’ll notice the difference immediately. No more cold drafts sneaking through gaps in January. No more cranking up the heat just to feel comfortable in your own living room.
Your energy bills drop because your HVAC system isn’t working overtime anymore. High-performance windows keep the temperature where you set it, whether it’s 15 degrees outside or 90.
The condensation problems disappear too. You know that moisture buildup between panes or around frames that makes you worry about mold? Gone. New windows with proper seals and quality glass eliminate those headaches entirely.
And your home looks better. Fresh windows update your entire exterior appearance, which matters whether you’re planning to sell or just want to feel proud when you pull into your driveway.
Sullivan Contracting has been handling window installation projects throughout Bozrah and eastern Connecticut for years. We understand how Connecticut weather tests windows – from ice storms to humid summers.
You’re not getting a crew that learned window installation from YouTube videos. Our installers know proper flashing techniques, understand vapor barriers, and won’t leave gaps that turn into problems later.
We work with quality manufacturers and back our installation with warranties that actually mean something. When we finish your project, you get windows that perform the way they’re supposed to.
First, we measure your existing windows and discuss what you want to accomplish. Better energy efficiency? Easier maintenance? Improved appearance? We match the right windows to your goals and budget.
Once you approve the estimate, we order your windows and schedule installation around your convenience. Most residential window replacement projects take 1-2 days, depending on how many windows you’re replacing.
During installation, we protect your floors and furniture, remove old windows carefully, and install new ones with proper sealing and insulation. We clean up completely and walk through everything with you before we leave.
You get windows that fit correctly, seal properly, and come with manufacturer warranties plus our installation guarantee. No callbacks needed because we did it right the first time.

You get complete window replacement, not just the glass. We remove your old windows, install new frames, ensure proper insulation and weatherproofing, and handle all the finishing work including trim and caulking.
We work with vinyl, fiberglass, and composite windows from manufacturers who stand behind their products. These aren’t the cheapest windows available – they’re the ones that actually save you money long-term through better energy performance and lower maintenance.
Every installation includes proper flashing and sealing techniques that prevent water infiltration. In Bozrah’s climate, this isn’t optional. Poor sealing leads to rot, mold, and expensive repairs down the road. We’ve seen too many DIY jobs and cut-rate installations that created bigger problems than they solved.
