Sealing

Sash windows are beautiful in older buildings, however they require maintenance. They are susceptible to issues such as wet-rot, cracked putty and draughts. It is possible to reduce energy loss and improve the efficiency of windows with sash by replacing them, repairing or sealing them.

The gaps between the sash and frame are the primary source of draughts. They can also cause noise and rattling, which can reduce soundproofing. Different methods can be employed to limit air leaks within the sash window, such as sealing beads, specialty products and secondary glazing.

A common issue is a gap that exists between the top of the sash and the jamb frame or between the bottom of the sash and the sill. This can result in water leaking into the wood and rotting of the wood and growth of mould. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.

If a gap is hindering the windows from opening and closing without a hitch, it might be necessary to put in new sash runners or spring bronze. These strips of bronze are tied or stapled to the sash's lower edges to prevent the rattling of the sides. They can be bought at DIY stores. Tubular weatherstripping also can be used, but it is prone to tear and can detract the appearance of your window.

It is important to measure the entire window opening prior to installing a replacement sash runner. It is best to measure from the top of the sash up to the horizontal centerline of the rail that connects it and from the bottom of the sash down to the sill. These measurements can be transferred to the new runners, which will help ensure a proper fit and better operation of the window.

In older buildings the gap between frame and sash is typically larger around the leading edge. It is possible to draught-proof it using a strip of V-strip which is self-adhesive. However, it is important to consider this when measuring and cutting material.

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 cut square and positioned so that the ends are matched to the angle of the window sill.

It is often possible to fix a poor seal using a couple of simple fixes, rather than tearing out the entire frame and reinstalling it.

To start a repair project take out the window stops (the moldings on the front of the lower sash). Then you can loosen the staff, and pull the lower window sash. Remove the chains or cords on both sides. Lastly take the sashweights out of the bottom of the cavity for weight. Place the hardware in a secure place. The heat gun will soften hardened filler or putty. Scrape it off with a putty blade. Reassemble the window. Reattach the hardware. Lubricate the pulleys using Teflon or silicone spray.

Unscrew the sash stops (a thin vertical strip of wood that is used to hold the sash) and remove any paint-encrusted hardware. Pull the sash to reveal the weight balancing, which is a large iron cylinder that is encased inside a hidden compartment and held by a rope. To keep the sash from falling into the void pierce it with an hammer and then sacrifice the weight.

After the sashes have been removed clean the jambs and the rails that meet. Remove the glazing bars and cords for the sash. Then employing a utility blade, remove any paint from the sash stop. Reattach the stops once the sashes have been reinstalled. Use nails that are small enough not to puncture the weight of the balancing.

To reassemble the sash place the top sash on its track first, and then the lower sash. Check that the sash stops and the frame are aligned properly. If needed, reconnect any beads used for parting. Then, reconnect the sash chain or cords and re-install the sash pulley axles.
