The methods that we use to restore windows are essentially the same as those used to originally build and operate the window.

Sash cords are replaced with copper chain. Chain is actually historically correct as often seen in larger buildings and churches. We prefer chain because, when properly installed, it will never wear out, is no noisier than rope and its patina will darken and blend into the original woodwork within a few months time. We can of course restore windows with rope when requested.

Spring Bronze weather-stripping is installed to the frame of the window. These metal strips are also historically correct and offer the best energy efficient solution while increasing the ease of use of wooden windows.

Read more about our Mechanical Restoration. “Windows should not be replaced unless absolutely necessary...wood windows are energy efficient [and] in conjunction with a standard exterior storm, provide a better energy efficiency than double glazed (thermo-pane) windows. Older wood windows do not necessarily have higher maintenance costs. For example, replacing the glass in many of the newer windows is very expensive and can sometimes require throwing away the sash and ordering a new one.”

The Brookline Planning Department“Window replacement is not a way to save a lot of money on heating or cooling costs. Research shows that old windows can be made virtually as energy efficient as new ones for less money. The "R-Value" (resistance to conductivity) of an original wood window, plus a good aluminum storm is the same as a double insulated replacement window...Consumer Reports sites only a modest drop in heating and cooling costs using top of the line windows, far from offsetting the thousands of dollars spent on new windows.”
