Professional window installation that cuts your energy bills and makes your home comfortable year-round.
Hear from Our Customers
Your energy bills drop. That’s usually the first thing homeowners notice after we finish a window installation project.
But the real difference shows up in how your home feels. No more cold spots near windows in winter. No more cranking the AC because the sun turns your living room into a greenhouse. No more fighting with windows that stick or won’t stay open.
New windows installed correctly make your whole house more comfortable. You’ll sleep better without street noise filtering through old, loose-fitting frames. Your furniture won’t fade from UV exposure. And when it’s time to sell, buyers notice quality windows immediately.
We’ve been handling window installation projects throughout Occum and eastern Connecticut for years. We know how New England weather tests windows, and we install them to last.
Most window problems aren’t actually window problems. They’re installation problems. A quality window installed poorly performs worse than a basic window installed correctly. That’s why we focus on proper measurement, weatherproofing, and structural integrity with every installation.
We work with homeowners who want the job done right without the runaround. No high-pressure sales tactics. No surprise costs. Just straightforward window installation backed by our work.
We start with accurate measurements at your home. Every window opening is different, even in the same house, so we measure each one individually. We’ll also assess the condition of your window frames and discuss any structural issues upfront.
Once we order your windows, we schedule installation when they arrive. We protect your floors and furniture, remove old windows carefully, and prep each opening. The new window gets properly sealed, insulated, and secured. Interior and exterior trim work comes next.
We clean up completely before we leave. You’ll get care instructions for your new windows and warranty information. The whole process typically takes one day for most homes, though larger projects might need two days.
Ready to get started?
Every window installation includes proper weatherproofing, insulation, and trim work. We don’t just swap out the window and leave. You get complete installation that addresses air sealing, water management, and structural integrity.
We handle permits when required and make sure everything meets local building codes. Connecticut’s weather demands proper installation techniques, especially around air sealing and moisture management. We use appropriate flashing, sealants, and insulation for our climate.
You’ll also get manufacturer warranty information and our installation warranty. We stand behind our work because we do it right the first time. Most installation issues show up within the first year, and we address any problems that arise from our workmanship.
