Sash Window Repairs

If sash windows aren't properly maintained they can lose functionality. This can cause drafts, energy inefficiency, and moisture damage.

Paint can crack and peel, leaving the wood exposed to the elements. Specialized joiners can repaint or re-stain it to repair any damage.

To repair damaged sash cords, first open the window and look for the parting bead, which is a thin strip of wood that divides the upper and lower sashes. Gently pry the bead away from the frame using the screwdriver. After removing the bead, you can begin to remove the sash. Once the sash is completely removed, you will need to find the two cast iron weights that are housed in a pocket on the opposite side of the sash. Typically, there is one weight in the back (towards the exterior of the window frame) and the other in the front (towards the inside side of the frame). Take both weights off and set them in a separate area.

After removing the counterweights from the sash channels, remove the access panel. Depending on the kind of window you have, there could be screws or a chisel available to assist you in removing the panel. You can see the spring coil that retracts the sash window replacement cords after the panel has been removed.

Once the cords are tied and secured, you are able to replace the access panels and jambliner, and put the sash back in place. Double-check that the new cords are long enough and secure. After that, you are able to insert the sash cords into the slots and holes on the sides of the lower sash and put the counterweights back in their pockets. Now, you can test your work. Slide the sash up-and-down to ensure it moves smoothly.

Drafts and air leaks

Sash windows can develop drafts or air leaks due the age of the window, damage or poor construction. These issues can be a sign that windows are in need of being replaced. However, they can be repaired with a bit of effort.

Weather stripping that is worn out or missing could cause air leaks and drafts. Foam tape or similar products should be used to seal the gaps between the sash and frame. This will help seal the gap, and block hot or cold air. If the weather stripping is not present or damaged, or folded over, it can cause drafts and a lack of energy efficiency.

A high-quality scraper like the Bahco makes this task much easier by allowing you to adjust the replaceable blades to get just the right angle for curving areas of the sash.

Frame Damaged

The earliest sashes were joined by using tapered wooden pegs that were driven through a mortise and tenon. This kind of joint can be more difficult to disassemble and you'll need the aid of a handsaw, knife or a sharp object to cut the glueline. Sashes made later used glue, which is more simple to separate.

After the sash is repaired, it's now time to put the track made of vinyl into the frame. Utilize a screwdriver to loosen the pawls of each locking terminal, and then lower the sash until it rests within the vinyl jamb liners and snaps into its place.

Before reinstalling the sash it is important to set it in glazing putty. You can purchase this mix of linseed and chalk at any hardware store. Make sure you have a few extra chalk bits on hand to ensure that the putty stays in good shape and also to help tidy up. After mixing the putty, work it until it's smooth and add additional chalk as needed to ensure an even consistency.
