Sash Windows Repair and Replacement

Sash windows older than 20 years can have various issues that include rattles and draughts. They may also be inefficiently insulated. A little care can often bring them back to their original performance.

First, take off the paint seal using an utility knife. Then remove the staff bead and remove the upper sash and remove the chains or cords and storing the equipment in a bag labeled.

Sealing

Sash windows are beautiful in old buildings, however they do need maintenance and can be subject to problems like cracked putty, wet rot and draughts. It is possible to reduce energy loss and improve the efficiency of windows with sash by replacing them the windows, repairing or sealing them.

Draughts are mostly caused by gaps between the sash and frame. They can also lead to rattles and reduce sound-proofing. There are a variety of methods to stop air leaks from a sash window, including sealing beads, special products, and secondary glazing.

A gap between the top or bottom of the sash and the jamb frame, is an issue that is frequent. This can cause moisture to leak into the wood, rotting it and growth of mold. Seal the gap with silicone, polyurethane, or foam sealant.

Installing a new sash runner or spring bronze might be necessary when a gap is preventing the windows from opening and shutting smoothly. These are bronze strips that are stapled or nailed into the edges of the lower sash to stop sideways rattle. They can be purchased from DIY stores. Tubular weatherstripping also can be used, however it is more likely to tear and can detract the appearance of your window.

When installing replacement runners for sash It is crucial to measure the window opening. It is recommended to measure from the top of sash up to the horizontal line 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 help ensure a perfect fit and better operation of the window.

In older buildings there is a greater gap between the sash and the frame around the leading edge. It can be draught-proofed using a strip of V-strip that is self-adhesive. However, it is important to consider this when measuring and cutting the material.

A piece of material should be cut to the height of the sash. There should be an extra inch to allow for movement. It should be cut squarely and positioned to align with the angle of the sill. Use stainless steel screws as brass may be rusty. Also, make sure to use a high quality silicone or polyurethane glue.

Refurbishment

The sash is a stunning historic feature in many homes. These windows are gorgeous but they can also be prone to problems. Draughts, rattling or leaking are common issues. Frames that are rotting and rails that connect them, as well as broken glazing bars, damaged frames, or rotten weights can all cause problems. When these issues arise, it's time to consider repairs or replacements to your sash.

Refurbishment is a more expensive option than simply replacing the sash itself but it can restore the look and function of your sash window as good if not better than the original condition. It involves lining the meeting rail and sash boxes with traditional putty and repairing any damage caused by rot. Re-painting the frame of the timber is also included, as well as re-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). In addition, it is recommended to install brush pile weather strips in order to minimize the rattling and increase insulation.

If the need for a new sash arises the frame can be constructed from like-for-like designs to match the old frame and maintain the character of your house. This is particularly important for listed buildings where any changes to the windows will require planning permission.

Before putting the new window on, it's best to check the metal tabs against the tabs on the old sash (see below). If the tabs are different shapes, the new sash will not fit properly into the window frame slots.

When a window is damaged it is essential to decide between repair or replacement because each kind of work will require a different degree of expertise and expense. If a large portion of the glass in a sash is missing replacing it is a better option. However, if the glass is damaged in a tiny section or a sill has been decaying, a repair may be more appropriate.

Replacement

Many homeowners would like to keep their old sash windows in good condition, but it is inevitable that deterioration will cause problems such as rattles or draughts. Broken glass can also occur. This is why it's often the only solution to these problems. But there are ways to improve sash windows beyond just replacing them, such as installing draughtproofing and secondary glazing.

It is important to determine the severity of the issue, since it might not be practical to replace an entire window. For instance, a fogging glass issue is usually a problem within the sash itself and is typically a solution without tearing out the entire frame. A leaky seal can often be remedied with a few simple fixes instead of a costly full-frame tear-out and replacement.

Sash windows are surprisingly complicated in their design and come with many moving parts. This is why it can be difficult to solve common issues like sash cords that are snapped or broken panes. The solution to these issues typically involves removal of the window frame which isn't something the majority of homeowners would like to tackle on their own. Many homeowners opt to engage a professional for these reasons.

Specialists can restore sash window frames back to their original glory or bring them up-to-date with the latest energy standards. This could include reconditioning the frames and fitting secondary glazing, to avoid heat loss through the window. It may also be beneficial to install a brush pile strip, to stop rattling, and reduce drafts.

To start a repair project, remove the window stops (the moldings that are in front of the lower sash). Then, loosen the staff bead, then take off the lower sash. Take off the cords or chains on both sides. Then, remove the sash weights from bottom of the cavity and take them off. Store the hardware in a safe location. Use a heat gun to soften hardened filler or putty. Scrape it off with a putty blade. Reassemble the window, reattach the hardware and lubricate pulley axles using silicone or Teflon spray. Install the parting beads and then reinstall the upper sash.

Repair

It is important for homeowners to decide whether to replace or repair their sash windows. Although modern replacements offer a host of benefits but the original features of a home that was built earlier provide personality and value to the home and are usually cheaper to repair than replacing them. Maintaining them in good shape can help save on energy costs. Sash windows are susceptible to drafts and rattles. This can lead to higher energy bills and damage the frame and the sash.

Sash windows can be a challenge to open and close. The mechanism for sliding could be slack or become draughty. It is best to leave the repair of window with sash to a specialist, as it requires extensive removal. With the right tools and skills it's possible to repair an old sash window yourself. Adam shows Jess the basics:

The process of bringing the window apart starts by removing any security fittings on the front of the lower sash. Next, remove the staff bead, then take the sash off the bottom. Remove the cords and chains from both sides, and knot them in a way that they can't be pulled back by the attached weights. The next step is to take out the upper sash. Take out the sash stops, a thin vertical wood strip that holds the sash. Also, take off any painted-covered hardware. Reverse  window repair  to reveal the weight. It is a large iron or lead cylinder that is hidden in a cavity and is secured by a cord. To stop the sash from falling into the void, pierce it using a nail, and sacrifice the weight.

When the sashes are untied clean the jamb and rails that meet, remove the glazing bars and sash cords, and scrape off any paint from the sash stops with an utility knife. Reattach the stops when the sashes have been reinstalled. Use nails that are not large enough to puncture the balancing weight.

Reassemble the sash by placing the upper sash first on its track, then the lower sash. Make sure the sash stoppers are properly aligned with the frame, and then reattach the beads that separate if required. Finally, reattach the sash chain or cords and re-attach the axles for the sash pulleys.
