Why repair wood windows instead of replacing them

Old-growth wood in windows from the 1900s to the 1950s is denser and more rot-resistant than most lumber used today. With new weatherstripping, sealed glazing and working sashes, a restored wood window can be close to as comfortable as a new one, and it keeps the look of your home. Restoration is often the right choice for historic Chicago bungalows and homes in landmark districts.

How we work

We look at every window, mark what needs repair and give you a price per window. Depending on the work, we repair sashes on site or take them to the shop and reinstall them, covering the openings in the meantime. One customer had 20 wood windows restored after getting quotes for full replacement.

When replacement makes more sense

If the frames are badly rotted or the windows were poor quality to begin with, we will say so and can quote replacement windows instead.

Wood window questions

Can old wood windows be made energy efficient?

Yes. New weatherstripping, fresh glazing, working locks and good storm windows make a big difference. Many restored wood windows perform close to newer windows.

My wood windows are painted shut. Can you open them?

Yes. We cut the paint seal, free the sash, clean the tracks and adjust the window so it opens and closes again.

Do you replace sash cords?

Yes. We restring broken sash cords and rebalance the weights on traditional double-hung wood windows.

How long does wood window restoration take?

Simple repairs take a visit. Full restoration of several windows can take a few days to a couple of weeks depending on the number of windows.
