There are many reasons to choose window restoration. Here are just a few:

• historic preservation - you only get one chance to save your building's original or early windows; once they are gone you can't get them back!
• sustainability - your windows have lasted for many years (some for 100 or more!) and were made to last the life of the building. With proper maintenance you can retain those windows for many, many years to come.
• energy efficiency - it is widely agreed upon by energy efficiency experts that replacing your windows is one of the last places you should spend your weatherization dollars. There is also a growing body of evidence suggesting that restoring your existing historic or older windows, along with correctly installed storm windows provides as much energy efficiency as replacement with new double glazed sash - but without requiring new materials or the environmental costs of throwing your historic windows in a landfill.
• pay-back period - with simple maintenance and "tightening" of you older windows you can see immediate improvements in the overall infiltration of outside air during the winter months. This tightening can result in energy savings in the first year of service, meaning you have paid back the costs of maintenance almost immediately.
• aesthetics - original or early windows just look right! Replacement windows never match the proportion, mass and detail of the windows they are replacing. Your building looks the way it looks because it is the visual combination of many features. Just like the eyes are inseparable from the face, so too are windows from the overall aesthetic appeal of the building.
• ease of operation - while you may not be able to believe it now, your windows once operated really well - and that includes the top sash! Over the years, paint buildup, nails, old weatherstripping, broken sash cords and poor maintenance have made them difficult if not impossible to operate. THIS CAN BE FIXED! Once restored your windows will operate as well, if not better than they did when they were first installed.
