Sash Windows Repair and Replacement

Sash windows that are older than 20 years old can be afflicted with many issues such as rattles and draughts. They might also be poorly insulated. A little care can often restore them to a high standard of performance.

First, take off the paint seal using an utility knife. Remove the staff bead, pull out the upper sash and take out any chains or cords. Keep the hardware in a bag with an identification label.

Sealing

Sash windows are gorgeous in older structures, but they require maintenance. They can be affected by issues like wet-rot, cracked putty and draughts. Repair, sealing, or replacement of the sash window is an effective method to minimize these issues and improve energy efficiency.

The gaps between the sash and frame are the primary source of draughts. They can also cause rattles and reduce sound-proofing. Various methods can be used to reduce air leaks in windows with sash, including sealing beads, special products and secondary glazing.

A common problem is a gap that exists between the top of the sash and the jamb frame, or between the bottom of sash and the sill. window repairs can lead to moisture leaking in, rotting wood and the growth of mold. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.

If a gap in the window is preventing the windows from closing and opening without a hitch, it might be necessary to install new sash runners or spring bronze. These bronze strips are stapled or nailed to the lower sash edges to stop sideways rattling. They can be purchased at DIY stores. Tubular vinyl weather-stripping is another option but it can tear, and can detract from the appearance of windows.

It is important to measure the entire window opening prior to installing a replacement sash runner. It is recommended to measure from the top of the sash to the horizontal line of the meeting rail, and from the bottom of the sash down to the sill. These measurements can be incorporated into the new runners, which will ensure a good fit and better operation of the window.

In older buildings there is a larger gap between the sash and the frame at the leading edge. It can be draught-proofed by a self-adhesive Vstrip, however it is essential to consider this when measuring and cutting the material.

A strip should be cut to the height of the sash, with an additional inch each side to allow for movement. The strip should be cut square and placed in a way that the ends are aligned to the angle of the window sill. Make sure to use stainless steel screws since brass may rust. Also, make sure to use high-quality silicone or polyurethane glue.

Refurbishment

The Sash window is a beautiful, historic feature of many homes. But despite their beauty, these windows are prone to a variety of problems. Draughts, rattling, sticking or leaks are all common problems. Frames that are rotting and rails that meet, as along with broken glazing bars, defective frames or weights that are rotten can cause issues. If you encounter any of these issues, it is time to replace or repair your sash.

It is important to decide if you want to replace or repair the damaged window, since each will require a different level and cost of knowledge. For example the case of a sash windows that has a large chunk of glass that is missing, then replacing it is the best choice. But when the glass has been damaged in a tiny section or a sill is rotting then a repair will be the better option.

Replacement

While a lot of homeowners are eager to keep their old windows in good order, deterioration can eventually cause issues such as rattles, draughts or even broken glass. These issues usually lead to a replacement as the only sensible solution. However, there are ways to improve sash windows beyond just replacing them, like installing draughtproofing and secondary glazing.

It is usually possible to fix a weak seal with a few simple fixes, rather than tearing out the entire frame and replacing it.

Sash windows are a complicated design that has many moving parts. This is why it can be tricky to solve common issues such as snapped sash cords or broken panes. The solution to these issues typically involves removal of the window frame which isn't something most homeowners want to tackle on their own. Because of this, many homeowners choose to work with a specialist.

Specialists can restore sash window frames back to their original glory or update them to meet modern energy standards. This could include reconditioning frames and fitting secondary glass to stop heat from getting out of the window. It is also possible to put in a brush pile strip, to stop rattling and reduce drafts.

To begin a repair, remove the window stops. (The moldings that are on the side of the lower glass). Next, remove the staff bead, then take off the lower sash. Remove the chains or cords that are on both sides. Finally, disconnect the sash weights from bottom of the cavity and remove them. Place the equipment in a secure place. Soften any old, hardened putty or filler using a heat gun, and scrape it away with the help of a putty knife. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray. Install the parting beads again and reinstall the upper sash.

Repair

The choice of replacing or repairing the sash window is an important one for homeowners. Modern replacements are beneficial in many ways however, the original features of an older home can add authenticity and value. They are also less expensive to repair rather than replace.

Sash windows are notoriously difficult to open and close as the traditional sliding mechanism can become dislodged from its track or become draughty. It's best to leave the repair of a window sash to a professional because it requires a lot of removal. But, with the right tools and experience, it is possible to repair old windows using sash. Adam shows Jess how to get started:

Getting the window to come apart starts with the removal of any security fittings on the front of the lower sash. Then, remove the staff bead and pull out the bottom sash. 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 attached weights. It's now time to remove the upper sash. Unscrew the sash stops (a thin vertical strip of wood that supports the sash) and remove any paint-encrusted hardware. Unscrew the sash to reveal the balancing weight, that is a massive lead or iron cylinder enclosed in a hidden cavity and anchored by rope. To prevent the sash from falling into the void, pierce it with a nail and sacrifice the weight.

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

To reassemble the sash place the top sash onto its track first, then the lower sash. Make sure the sash stoppers are in the correct alignment with the frame, and then reconnect the beads that separate if required. Reattach the sash cords or chains and then install the sash pulleys.
