Sash Damaged Sash

Even sash windows that have been maintained need to be checked on from time to time. Broken cords, drafty frames and meeting rails decaying sills, loose glue and beading, cracked glass, and damaged paint are all common problems that may lead you to consider replacement. In many cases, these problems can be resolved without having to replace the entire window.

For example, broken cords are usually caused by old or poorly-fitting window hardware that has deteriorated. A quick examination of the window hardware will confirm if this is indeed the situation. Pam says to pull on the cord and move the sash up and down -- if it is able to move easily and is free of any major friction, the sash can likely be repaired.

If the sash is hard to move or has lots of friction it could be due to the sash. Pam suggests spraying silicone or Teflon on the pulleys of the sash to make it easier for you to shut and open. She also recommends fixing any broken hardware, such as misaligned or missing pulleys and sash weights.

Another easy repair is restoring the wood on the frame by painting the damaged parts. This will shield the wood from further damage, and prevent moisture penetration and the development of rot.

Finally, if the sash has been painted, Pam suggests lightly sanding down the painted surface before priming it with a high-quality primer. She recommends a semi-gloss urethane. This will prevent the paint from peeling, flaking or blistering and allow the sash to slide easily.

Pam recommends that when installing the sash, you check the tabs made of metal on the new sash to those on the old sash to ensure they are in the correct slots. If you don't take this step then the sash will not be able to slide upwards and down. If needed apply wood filler to smooth out the join. If there is cracks, she recommends replacing the entire sash.

Water Damage

Insufficient weather sealing allows moisture to enter the frame, causing water damage. Untreated, this dampness can cause decaying wood. This is why it's important to check your sash window frequently. Look for signs such as peeling paint, visible decay, and the growth of mold that could be a sign of a damaged sash.

Water damaged sashes aren't just harmful and ugly, but they also look unattractive if they're exposed to sunlight or in a prominent location. It's a good idea to consider replacement sash windows with laminated glass to minimize the impact of UV rays on your home.
