Sashes that stick Sashes

It's a nightmare if your double-hung windows get stuck. You'll lose your view when they squeak in a storm. On the other hand, a window that's too loose will allow external air and noise through and your energy costs can increase. Both of these scenarios are not optimal but they can be corrected by using the appropriate tools and persistence.

Paint can accumulate on the channels of old weighted window tracks, causing them to block. Most of these problems can be solved by cleaning and oiling the tracks.

Begin by removing the caulking between the window stop (the internal one) and the window frame. Then scrape away any paint that has accumulated. Use a sharp knife and put sheets of plastic as well as a dust-collecting vacuum cleaner below the surface to catch any paint dust or chips.

Clean the tracks using a dry cloth, and apply a silicone-based lubricant to make them more gliding. You can find this at the majority of home improvement stores or online. Then, you can move the sash up or down to test it.

Once the pockets are removed, you can start chiseling out any wood rot and apply an extremely high-quality water-resistant filler. After the filler is dry, a primer coat should be applied to prevent further decay.

It is a smart idea to inspect inside the window repairs the weights of the sash to ensure that they are in balance. They should not be in the wrong alignment, or pulling one side harder than the other. If they aren't balanced, the sash could fall off its track and cause damage to the frame.
