Professional installation, energy-efficient windows, and no surprises – just comfortable rooms and lower heating bills.
Hear from Our Customers
Your heating bills drop because air stops leaking through gaps and cracks. Those cold spots by the windows disappear, and you stop cranking the thermostat to compensate for drafty rooms.
You get consistent temperatures throughout your home. No more avoiding certain rooms in winter or dealing with condensation that fogs up your view and damages your window frames.
Modern windows also cut down on outside noise, protect your furniture from UV damage, and give you better security with updated locking systems. When you’re ready to sell, buyers notice quality windows – they’re one of the home improvements that actually add value you can measure.
We’ve been installing windows in southeastern Connecticut for years. We understand what works here – from the salt air near the coast to the freeze-thaw cycles that crack inferior installations.
We’re licensed, insured, and we live in the communities we serve. When you call us back in five years because you have a question, we’ll still be here. That matters when you’re making an investment this size.
First, we measure your existing windows and discuss your priorities – energy savings, noise reduction, or specific style preferences. We’ll show you options that make sense for your home and budget, not just the most expensive ones.
Installation day starts with protecting your floors and furniture. We remove old windows carefully to avoid damage to your siding or interior trim. Each new window gets properly sealed and insulated – this step separates professional installation from quick jobs that cause problems later.
We clean up completely before we leave. You’ll have new windows that open and close smoothly, lock securely, and keep your home comfortable. We’ll walk through everything with you and answer any questions about operation or care.
Ready to get started?
Every window installation includes proper sealing, insulation, and weatherproofing designed for Connecticut’s climate. We don’t cut corners on the details that prevent air leaks and water damage down the road.
You get manufacturer warranties on the windows themselves plus our guarantee on the installation work. We use quality materials – proper flashing, expanding foam insulation, and exterior caulking that won’t crack or shrink over time.
We handle the permit process if your project requires it, and we coordinate with you to minimize disruption to your daily routine. Most installations are completed in one or two days, depending on the number of windows and any complications we discover.
