Hear from Our Customers
Your energy bills drop because your windows actually seal properly. No more cold spots in January or rooms that won’t cool down in August.
You get consistent temperatures throughout your home. The constant battle with your thermostat ends when your windows stop working against you.
Your home looks updated and feels more secure. Modern windows with proper locks and weatherproofing give you both curb appeal and peace of mind. You’re not dealing with windows that stick, leak, or let in every sound from outside.
We’ve been installing windows in Connecticut for years. We understand what works here and what doesn’t.
Connecticut weather is tough on windows. The freeze-thaw cycles, humidity, and temperature swings demand proper installation and quality materials. We’ve seen what happens when corners get cut.
You get straight answers about what your home needs. No overselling, no surprise costs, and no shortcuts that cause problems later.
We start with measuring your existing windows and discussing your needs. You’ll know exactly what you’re getting and what it costs before we start.
Installation day means protecting your home while we work. We remove old windows carefully, prep the openings properly, and install your new windows with attention to weatherproofing and insulation.
Cleanup and final inspection happen before we leave. You get windows that open smoothly, lock securely, and seal completely. We walk through everything with you so you know how your new windows work.
Ready to get started?
Your window installation includes proper weatherproofing and insulation around each opening. This isn’t just dropping windows into holes – it’s making sure they perform.
We handle trim work and finishing so your windows look intentional, not like an afterthought. Interior and exterior trim gets attention because details matter for both appearance and weather protection.
You get manufacturer warranties on the windows plus our installation warranty. Connecticut weather tests everything, so you need coverage that accounts for real-world conditions, not just product defects.
