Window Restorations of Connecticut, formerly Bi-Glass of Connecticut, works on original wood windows instead of replacing them. The company describes itself as the option for homeowners who want to keep those windows but have them work and save energy like a new one, and it says it has been in business 32 years. A recent customer with 26 original windows in a 1914 home said many were rotting, most were painted shut and the rope-and-pulley mechanisms were barely functioning. That customer wrote that the company restored them, added double-pane glass and left the home quieter and more comfortable. The same customer said four arched attic windows were restored as well and new leaded-glass sidelights were made for the front entry, and that Jim patiently answered all of their questions. A 2022 customer with a 200-year-old home of about 50 drafty windows said the company kept the old frames and, with carpentry, turned them into tight-fitting thermal windows. That 2022 customer also said the process was not cheap.
Beautiful work! I had 26 original windows in my 1914 home that were in desperate need of restoration. Many were rotting, most were painted shut, and the original rope-and-pulley mechanisms were barely functioning. WRC restored them beautifully, preserving their historic character while making them fully functional again. I can’t get over how much quieter and more comfortable my home is with the addition of double-pane glass. I only wish I’d done this sooner! Four of my attic windows are beautiful arches that would be nearly impossible to replace. WRC restored those as well and even created gorgeous new leaded-glass sidelights for my front entry. Jim is incredibly knowledgeable and patiently answered all my questions (and there were many!). His team is skilled, professional, and trustworthy. I couldn’t be happier with their work and highly recommend Window Restorations of CT!
My wife and I own a 200 year old home, which has about 50 windows. We needed to replace the extremely old and drafty windows but didn't want new cheap frames with thermal windows. Window Restorations solved the problem. They use the actual centuries-old frames and, with expert carpentry, transform them into a tight fitting thermal windows that keep cold New England winters from entering the house. The process isn't cheap, but it's a more beautiful solution and it preserves the value of your antique home.
