Restoring Windows vs. Replacing

 CLEARFIX Mobile LLC is dedicated to the restoration and preservation of old windows in historic homes and buildings. 

 “The common misconception that replacing windows will save as much as 50% in energy costs is simply not true. The windows in many historic buildings have functioned for more than 100 years and, with regular maintenance, will usually survive longer and work better than any replacement window.  A replacement window does not generally pay for itself in a reasonable length of time. Unlike historic windows, new window assemblies cannot be repaired; they can only be replaced once again. The sustainable choice is to repair historic windows whenever possible. Caulking, weather-stripping, and replacing deteriorated glazing compound to seal air leaks should always be done before considering replacing historic windows.”

 Replacement windows are a not a solution in any old building, as they will need to be replaced again in approximately 10 years.  New windows cannot be repaired and do not offer any additional energy efficiency as the window manufacturers and salespeople would have the public believe.  It would take hundreds of years to recoup any money spent on new windows. 

The original historic wood windows were meant to be repaired when they were fabricated. They have lasted for 70 to 100 or more years and were made from old growth wood, which is dense and repairable, unlike the disposable windows that are manufactured today. 

Taking the original windows out of an old house is like ripping out its’ heart and soul.  One important architectural aspect of the building is destroyed, and in our opinion, reduces the value of the building. Once the historic windows are gone, they are gone for good!

Same window, ready for another 100 years!


Large, round window from a circa 1902 Oscar Martin house located in Doylestown Borough.


It was in terrible shape and coming apart.  Fully restored here, and back into the building.
