Sash Windows Repair and Replacement

Sash windows older than 20 years may have many issues such as rattles and draughts. They could also be inefficiently insulation. A little care can often restore them to their original performance.

First, remove the seal on the paint of the window stop with a utility knife. Remove the staff bead, then pull out the upper sash, and remove any cords or chains. Keep the hardware in a container with an identification label.

Sealing

Sash windows look stunning in older buildings, however they require regular maintenance. They can be affected by problems like wet-rot cracked putty and draughts. It is possible to reduce energy loss and increase the efficiency of sash windows by replacing or repairing them, or sealing them.

Draughts are usually caused by gaps between the sash and the frame. They can also cause noise reduction and rattle. Sealing beads, special products, and secondary glazing can all be used to minimize the air leakage within a Sash.

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

If a gap is hindering the windows from opening and closing without a hitch, it might be necessary to install new sash runners or spring bronze. These are strips of bronze that are stapled or nailed to the edges of the lower sash to prevent sideways rattle. They can be purchased from DIY stores. Tubular weatherstripping also can be used, however it tends to rip and can alter the appearance of your window.

When replacing sash runners, it is important to measure the window opening. It is best to measure from the top of the sash 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 incorporated into the new runners, which will help ensure a good fit and better operation of the window.

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

The strip should be cut at the height of the sash with an inch more on each side to allow movement. The strip should be cut square and positioned in a way that the ends are aligned to the angle of the window sill. It is also essential to make use of stainless steel screws as brass can rust, and high-quality polyurethane or silicone adhesive.

Refurbishment

The sash is an attractive, historical feature of many homes. Yet despite their beauty, these windows are prone to a variety of problems. Common issues include rattling draughts or sticking. The rotted frames and the rails that connect them, as well as broken glazing bars, defective frames or weights that are rotten can all cause problems. When these problems occur it's time to consider upvc repairs or replacements to your sash.

Refurbishment is a more expensive alternative than replacing the sash, but it will bring back the appearance and function of your sash window as good, if not superior to its original state. It involves lining the meeting rail and sash box using traditional putty and fixing any rot-related damage. It also involves painting the timber frame and re-glazing with 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 install brush pile weather strip to reduce the noise of rattling.

If a new sash is needed it can be constructed with the same design to match your existing frame. This will preserve the traditional style of your home. This is especially crucial for listed buildings, where any changes to the windows will require planning permission.

Compare the metal tabs on the new window with the old sash prior installing it (see below). If they're different sizes the new sash may not fit in the slots of the window frame.

It is crucial to determine whether to repair or replace the damaged window, since each choice will require a different level and level of knowledge. For instance when a sash window has a large chunk of glass that is missing, then replacement is the best option. But when the glass is damaged in a tiny section or a sill has been damaged, a repair would be more appropriate.

Replacement

Many homeowners would like to keep their old sash window in good condition, however it is inevitable that deterioration will cause problems like rattles or draughts. Broken glass may also occur. These issues typically point to an inevitable replacement as the only feasible solution. However, there are other ways to improve the sash windows beyond just replacing them, including installing draughtproofing and secondary glazing.

It's important to consider the severity of the problem, as it may not be appropriate or even feasible to replace the entire window. For instance, a fogging glass issue typically occurs within the sash and is usually able to be resolved without ripping out the whole frame. A weak seal can be fixed by a few easy fixes instead of a costly full frame tear-out and replacement.

Sash windows are surprisingly complicated in their design and come with lots of moving parts. It can be challenging to fix common issues like cracked panes or sash cables that have snapped. Resolving these issues often requires removal of the window frame which isn't something that most homeowners would want to tackle on their own. Many homeowners choose to hire a specialist for these reasons.

A professional can help restore windows made of sash to their original splendor, or even bring them up to modern energy standards. This can include reconditioning the frames and installing secondary glazing to stop heat loss from the window. You can also install a brush-pile strip in order to minimize drafts and stop the window from rattling.

To begin a repair project, remove 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. Finally, remove the sashweights from the bottom of the cavity for weight. Store the hardware in a secure place. The heat gun will soften hardened filler or putty. Scrape it off using the blade of a putty. Reassemble the window, reconnect the hardware and lubricate pulley axles by using silicone or Teflon spray. Reinstall the parting bead, and reinstall upper sash.

Repair

The choice to replace or repair a sash window is an important one for the homeowner. Although modern replacements can provide numerous benefits, the original features of an older house provide personality and value to the home and are usually cheaper to fix than replacing them. Inspecting them regularly can lower the energy cost. Sash windows are vulnerable to rattles, drafts and condensation, and these issues can lead to higher costs for energy and damage to the frame and the sash.

Sash windows can be difficult to open and close. The mechanism that slides can become dislodged or become draughty. It's best to leave the repair of sash windows to professionals since it requires a lot of removal. However, with the right tools and know-how, it is possible to fix old windows with sash yourself. Adam shows Jess the basics:

Getting the window to come apart begins by removing any security fittings in front of the lower sash. Then, remove the staff bead. Then, remove the sash at the bottom. Remove the cords and chains from both sides, and knot them so that they cannot be pulled back by the weights. It's now time to take out the upper sash. Unscrew the sash stoppers (a thin vertical strip of wood that is used to hold the sash) and remove any painted-covered hardware. Unscrew the sash to reveal the weight balancing, which is a large iron cylinder or lead that is enclosed in a concealed cavity and secured 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 rails that connect them. Remove the glazing bars and the sash cords. Then employing a utility blade, remove any paint from the sash stop. After the sashes have been put back in place, you can reattach the stops using nails that are not too large to risk cutting the weight that is balancing.

To reassemble the sash, put the top sash into its track first, then the lower sash. Make sure the sash stops are in the correct alignment with the frame, and then reconnect the beads for parting if necessary. Reattach the sash chains or cords and attach the sash pulleys.
