New Windows and Doors—Enhance the Beauty and Value of Your Home

Trust the Professionals at LG Building with Window and Door Replacement

Did you know that about a third of the warm and cool air produced by your HVAC system can be lost through your windows or doors, particularly if those windows and doors have been in your home for a number of years. Furthermore, the life span of the average double-paned window is about 20 years. As your windows and doors age, they can start to show their age, detracting from the appearance and the value of your home. LG Building can help.

At LG Building, we have served the needs of homeowners across western Connecticut for more than three decades. We are family-owned and operated, with a singular focus on quality and craftsmanship. We always pay close attention to the details, and use only the highest quality materials in all our work. To learn about the full range of our services or to talk to us about window and door replacement, contact us online or call us at 203-264-2931.

We Make Window and Door Replacement Easy

At LG Building, we take the guesswork out of choosing the right windows and doors. We’ll visit your home, so that we can get precise measurements for all windows and doors. We’ll carefully explain your options, along with the advantages and disadvantages of different styles. We have longstanding relationships with the premier window and door companies in Connecticut, including Andersen and Marvin, and offer a full line of prefabricated or custom windows and doors. Because of the relationships we have built with vendors over the years, we are usually able to secure highly competitive pricing. We will also install the windows and doors, saving you money and avoiding the headaches that can come from dealing with different contractors for different jobs. We routinely find our cost estimates 20-35% less than quotes from the mass marketers.

With new windows and doors installed by LG Building, you can reduce your home energy costs, lower the volume of the noise coming in from your neighborhood, give your home a more pleasing appearance and even protect furniture and floors with the UV protection in many modern windows.
