Sash Windows Repair and Replacement

Older sash windows suffer from a range of issues including draughts rattles, and inadequate insulation. A little care can often bring them back to a high standard of performance.

First, remove the seal with a utility knife. Then remove the staff bead and take the upper sash out, taking off cords or chains and storing hardware in a bag marked.

Sealing

Sash windows are beautiful in older buildings, however they require maintenance. They are susceptible to problems like wet-rot cracked putty, and draughts. Repair, sealing or replacement of the windows in sash is a great way to reduce these problems and increase energy efficiency.

Draughts are mainly caused by gaps between the sash and the frame. They can also trigger noise reduction and rattling. Sealing beads, specialty products and secondary glazing can be used to limit the air leakage inside a sash.

A common problem is a gap between the top of the sash and the jamb frame or between the bottom of the sill and the sash. This can lead to moisture leaking into the wood, rotting it and growth of mold. The gap can be filled with silicone or polyurethane caulking or foam sealant.

If a gap is hindering windows from opening and closing easily, it could be necessary to install new sash runners or spring bronze. These strips of bronze are tied or stapled to the sash's lower edges to stop sideways rattling. They are available at DIY stores. Tubular vinyl weatherstripping can also be used, however it tends to rip and can alter the appearance of your window.

It is important to determine the size of the window opening before installing an alternative sash runner. It is recommended to take measurements from the top of the sash up to the horizontal centerline of the rail of the meeting and from the bottom of sash down to the sill. These measurements can be transferred to the new runners, which will help ensure a perfect fit and a better performance of the window.

In older structures the gap between frames and sash is typically greater around the leading edge. It is possible to draught proof by using a self-adhesive Vstrip, however it is important to take this into consideration when cutting and measuring the material.

The strip should be cut at the height of the sash, with an inch more on each side to allow for movement. It should be trimmed to a square shape and then positioned in a way that the ends are matched to the angle of the window sill. Use stainless steel screws as brass may rust. Also, use the highest quality polyurethane or silicone glue.

Refurbishment

The windows with sash are a stunning and historic feature of many homes. However, despite their beauty these windows are susceptible to a range of issues. Draughts, rattling or leaks are all common problems. Frames that are rotting and meeting rails as well as broken glazing bars, damaged weights or rotten frames are all causes of problems. If you are experiencing any of these problems it's time to replace or repair your sash.

Refurbishment is a more expensive alternative than replacing the sash, however, it can improve the appearance and functionality of your sash upvc window repairs to the same or better than the original condition. Refurbishment involves lining both the meeting rail and the sash box using traditional putty, and then repairing any damage caused by decay. Re-painting the frame of the timber is also included, as is glazing using traditional glass. A full refurbishment can also include adding draught proofing, re-attaching the sash furniture/ironmongery and replacing the parting bead (the dividing strip between the two panes of glass). It is also recommended to put in brush pile weather strips to lessen rattling and improve insulation.

If a replacement sash is required, it can be made using the same style to match your existing frame. This will maintain the style and character of your home. This is particularly important for listed buildings where any changes made to windows will require planning permission.

Before you put the new window in before installing it, make sure you check the metal tabs against those on the sash that was previously used (see below). If these are different shapes the new sash will not fit in the window frame slots.

It is crucial to determine whether to repair or replace windows that are damaged, as each choice will require a different degree and level of expertise. For instance when a sash window has a significant piece of glass that is missing, then replacement is the best choice. If the glass is only damaged in a tiny area or a sill is beginning to rot, then a repair would be more appropriate.

Replacement

Although many homeowners want to keep their old sash windows in good working order, deterioration can eventually cause issues such as draughts, rattles, or even broken glass. This is why it's often the only option to solve these issues. However, there are ways to improve sash windows that go beyond replacing them, such as installing draughtproofing and secondary glazing.

It may also be beneficial to add a brush pile strip to stop rattling and reduce drafts.

To start a repair project, remove the window stops (the moldings in front of the lower sash). Then, loosen the staff and pull the lower window sash. Remove the cords and chains from both sides. Finally, disconnect the sash weights from bottom of the weight cavity and remove them. Keep the hardware in a safe place. Use a heat gun to soften old, hardened filler or putty. Scrape it off with the blade of a putty. Reassemble the window, reconnect the hardware and lubricate pulley axles with silicone or Teflon spray. Reinstall the parting bead, and reinstall upper sash.

Making the window come apart starts with the removal of any security fittings that are in front of the lower sash. Then, take off the staff bead. Then, remove the bottom sash.

Remove the sash stops (a thin vertical strip of wood that supports the sash) and remove any painted-covered hardware. Unscrew the sash to reveal the balancing weight which is a large lead or iron cylinder enclosed inside a hidden compartment and secured by rope. To prevent the sash from falling into the void, hit it with an hammer and then sacrifice the weight.

After the sashes have been removed clean the jambs and meet rails. Remove the glazing bars and the sash cords. Then using a utility knife take off any paint from the sash stop.
