Out with the old and in with the new. Well, not so fast. Windows on many older and historic homes are a big part of a building’s architectural heritage and integrity, adding interest and individuality.
Simply sealing open cracks and refurbishing your existing windows can be the least expensive way to improve the energy efficiency of your windows. Of course, not all windows are easily refurbished, and it’s important to assess the architectural significance and physical condition of any window before undertaking the job. It’s inexpensive but labor intensive.
Are your windows original? Do they reflect a specific era or regional style? Even if they’re weather-beaten, are they an example of unusual or exceptional design or craftsmanship. If so, you might consider taking the time to restore them.
The greatest threat to any window is moisture, and areas of your window that are susceptible to water will be evident in peeling and blistering paint. But don’t despair. Excessive paint deterioration on the surface may be the result of neglect and won’t necessarily indicate frame decay. Use a sharp awl to test the condition of the wood in areas where paint has peeled or worn away, particularly in the lower portions of the frame.
If the wood is firm, take precautions to redirect water away from the window, possibly through the replacement of a more downward sill or by cutting a drip line on the underside of the sill. This is a thin cut which stops water from travelling around and into the framing. The edges of the frame and the joints of the window also need special protection from water. If the frame is sound, by removing old and blistering paint; weather-stripping; caulking; and replacing cracking putty and damaged glass, you’ll breathe new life into your home’s character and into your pocketbook.
