Professional installation, energy-efficient windows, and warranties that matter – installed by Norwich contractors who get it right.
Hear from Our Customers
Your energy bills drop. That’s the first thing you notice after quality window installation – heating and cooling costs that actually make sense for once.
But it goes deeper than savings. You stop hearing every car that drives by. Your home feels comfortable in every room, not just the ones with the thermostat. Those drafts that made certain spots unbearable? Gone.
New windows also mean your home looks updated from the street. Not just pretty – valuable. Real estate agents will tell you that quality windows are one of the improvements buyers actually notice and pay for.
Sullivan Contracting has been handling window installation in Norwich for years. We know Connecticut weather – the ice storms, the humidity, the temperature swings that make cheap windows fail fast.
You’re not getting a crew that learned window installation last month. Our installers understand proper flashing, insulation, and weatherproofing because they’ve seen what happens when it’s done wrong.
We’re licensed, insured, and we live here too. When we install your windows, we’re putting our reputation on every job site in town.
First, we measure everything twice. Your windows get custom-sized because standard sizes rarely fit older Norwich homes perfectly. No forcing square pegs into round holes.
Installation day starts with protecting your floors and furniture. We remove old windows carefully – no unnecessary damage to your siding or interior trim. Each new window gets properly flashed and sealed before we move to the next one.
The final step is cleanup and walkthrough. You’ll know how to operate your new windows, what warranty coverage you have, and how to reach us if anything needs attention. Most installations finish in one day, weather permitting.

Every window installation includes proper insulation around the frame, exterior caulking, and interior trim work to match your existing style. We don’t consider a window “installed” until it operates smoothly and seals completely.
You get manufacturer warranties on the windows themselves – typically 10-20 years depending on what you choose. Our installation work carries its own warranty because we stand behind the quality of our crews.
Norwich homes often need custom solutions. Older houses have settling, non-standard openings, or architectural details that require experience to handle properly. That’s exactly the type of work we do regularly.
