Hear from Our Customers
You know the difference when windows are installed right. No more fighting with sticky sashes or feeling cold air creep in around the edges. Your heating bills drop because warm air stays where it belongs.
The rooms feel comfortable year-round instead of being too hot in summer and freezing in winter. You stop worrying about whether your windows will hold up to the next storm.
When window installation is done properly with quality materials, your home works better. The temperature stays consistent. Energy costs go down. And you get the peace of mind that comes with windows you can actually rely on.
We’ve been handling window installation in Connecticut for years. We understand how our weather affects windows and what it takes to install them so they perform.
We’re licensed and insured, which means you’re protected. We pull the right permits and make sure everything meets local codes. Most of our work comes from referrals because people see the difference when windows are installed correctly.
We’ve worked on homes throughout Gilman and the surrounding areas. We know the common issues with older homes and how to address them during installation.
First, we come out to measure and assess what you’re working with. We look at the existing frames, check for any issues that need addressing, and discuss your options for new windows.
Once you’re ready to move forward, we order your windows and schedule the installation. We protect your home during the work and remove the old windows carefully. Each new window gets properly sealed and insulated to prevent air leaks.
We clean up completely and walk through everything with you to make sure it’s done right. You get warranty information for both the windows and our installation work. The whole process is designed to minimize disruption while making sure the job is done properly.

Professional window installation means more than just swapping out the glass. We handle the permits, make sure the installation meets Connecticut building codes, and address any structural issues we find.
Each window gets properly flashed and sealed to prevent water infiltration. We insulate around the frames to eliminate air leaks. If we find rot or damage during removal, we take care of those repairs so your new windows have a solid foundation.
Connecticut’s weather is tough on windows. We install them to handle our temperature swings, wind, and precipitation. That means using the right materials and techniques so your windows perform well for years, not just the first season.
