Installing a new sash runner or spring bronze might be required when a gap is preventing windows from closing and opening effortlessly. These are a type of bronze that are stapled or nailed into the edges of the lower sash to stop sideways rattle. They are available at DIY stores. Tubular vinyl weather-stripping is another option, but it is prone to tear, and can make a difference to the appearance of windows.

It is important 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 meeting rail and from the bottom of sash down to the sill.

The strip should be cut to the height of the sash, with an inch more on each side to allow for movement. It should be trimmed square and positioned in a way that the ends are matched to the angle of the window sill. Make sure to use stainless steel screws since brass can rust.

It is also possible to install an extra strip of brush pile to stop rattling and reduce drafts.

To start a repair project start by removing the window stops (the moldings on the front of the lower sash). Next, loosen the staff bead and remove the lower sash. Remove the chains and cords from both sides. Then remove the sashweights from the bottom of the cavity for weight. Store the equipment in a secure location.

Lubricate the pulleys with Teflon or silicone spray. Reinstall the parting bead, and reinstall upper sash.

Repair

It is important for the homeowner to decide whether to repair or replace their sash windows. While modern replacements provide numerous benefits, the original features of a home that was built earlier provide character and value to the property and are often cheaper to repair than replacing them.

Then, take the chains or cords on both sides and tie the ends to stop them from being pulled back into the frame by the weights that are attached. The next step is to take out the upper sash. Take out the sash stops which is a thin vertical wood strip that holds the sash. Also, take off any paint-encrusted hardware. The sash can be pulled back to reveal the balancing weight, which is a large iron cylinder that is encased in a concealed cavity and held by rope. To keep the sash from falling into the void pierce it with nails and remove the weight.

After the sashes have been removed clean the jambs as well as meet rails. Remove the glazing bars and sash cords. Then using a utility knife take off any paint from the sash stop. Reattach the stops once the sashes have been put back in place. Use nails that are small enough not to damage the balancing weight.

Reassemble the sash by putting the upper sash on top of its track, then the lower sash. Make sure that the sash stops are aligned properly with the frame, and reattach the beads for parting if necessary. Finally, reattach the sash chains or cords and then re-attach the sash pulley axles.
