Professional installation, energy-efficient windows, and the peace of mind that comes with hiring local Connecticut experts.
Hear from Our Customers
Your heating bills drop. Those drafts by the kitchen table disappear. You stop hearing every car that drives by, and your house actually stays the temperature you set on the thermostat.
That’s what happens when windows are installed correctly with the right materials for Connecticut’s climate. No more condensation pooling on the sills. No more fighting with windows that won’t open or close properly.
You get consistent temperatures throughout your home, lower energy costs, and windows that’ll last decades instead of needing repairs every few years. Your home value increases, and you stop worrying about whether your windows can handle the next nor’easter.
We’ve been installing windows in Quaker Hill and throughout southeastern Connecticut for years. We understand what coastal weather does to windows and how to install them so they last.
We’re not a national chain that rotates through different crews. When you call us, you get the same team that knows your project and can come back if you need anything. We live here, work here, and stand behind every installation.
First, we measure your existing windows and discuss your needs – energy efficiency, style, budget, timeline. We don’t push products you don’t need, and we explain why certain windows work better in coastal Connecticut.
Next, we order your windows and schedule installation around your life, not ours. Our crew protects your home’s interior, removes old windows carefully, and installs new ones with proper insulation and sealing.
Finally, we clean up completely, test every window, and walk through the project with you. You get manufacturer warranties on the windows plus our guarantee on the installation work.
Ready to get started?
Every window installation includes proper removal of old windows, disposal of debris, and complete cleanup. We handle permits when required and ensure all work meets Connecticut building codes.
You get quality windows designed for our climate – double or triple-pane glass, energy-efficient frames, and hardware that won’t corrode in salt air. We properly insulate around each window and seal against air infiltration.
Our installations come with manufacturer warranties on the windows themselves plus our workmanship guarantee. If something isn’t right, we come back and fix it. No arguing, no excuses.
