These bronze strips are attached by staples or nails to the lower sash edges to stop the rattling of the sides. They are available at DIY stores. Tubular vinyl weather-stripping is an alternative option, but it is prone to tear and detract from the appearance of windows.

It is crucial to take measurements of the entire window opening prior to installing the an alternative sash runner. It is recommended to take measurements from the top of sash up to the horizontal centerline on the rail that connects them and from the bottom of sash down to the sill. These measurements can be transferred to the new runners, which will ensure a proper fit and a better performance of the window.

In older structures there is a greater gap between the sash as well as the frame on the leading edge. It is possible to draught proof with a strip of self-adhesive V-strip, but it is crucial to take this into consideration when cutting and measuring the material.

To begin a repair, take off the window stops. (The moldings are located in front of the lower glass). Next, loosen the staff bead and remove the lower sash. Remove the cords or chains on both sides. Then, remove the sashweights from the bottom weight cavity. Keep the hardware in a secure position. Soften any old, hardened putty or filler with a heat gun and scrape it away using the help of a putty knife.

Repair

It is crucial for the homeowner to make a decision on whether to repair or replace their sash windows. Although modern replacements can provide many advantages but the original features of an older house give personality and value to the property and are generally less expensive to fix than replacing them.

Remove the sash stops and a thin strip of wood that is used to hold the sash. Also, take off any hardware that has been painted. The sash can be pulled back to reveal the balancing weight, that is a massive iron cylinder that is encased inside a hidden compartment and held by rope. To prevent the sash falling into the void, pierce it using a nail, and then let the weight go.

After the sashes have been removed clean the jambs and rails that connect them. Remove the glazing bars as well as the cords of the sash. Then using a utility knife take off any paint that is on the sash stop. When the sashes are returned to their original positions, you can attach the stops using nails that are small enough to avoid puncturing the weight that is balancing.

Reassemble the sash by placing the upper sash first on its track, then the lower sash. Check that the sash stops and the frame are aligned properly. If necessary, reattach any parting beads. Then, reconnect the sash chains or cords and re-install the axles for the sash pulleys.
