Sash Windows Repair and Replacement

Sash windows that are older than 20 years old can be afflicted with various issues, including draughts and rattles. They may also be poorly constructed to be insulated. With a little effort they can be repaired to a high level of performance.

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

Sealing

Sash windows look gorgeous in old buildings, however they require regular maintenance and could be susceptible to issues like wet rot, cracked putty, and drafts. It is possible to decrease energy loss and increase the efficiency of sash windows by replacing the windows, repairing or sealing them.

window repair are mostly 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 reduce the air leakage in the Sash.

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

If a gap in the window is preventing the windows from closing and opening smoothly, it may be necessary to replace sash runners or spring bronze. These are bronze strips that are stapled or nailed into the edges of the lower sash in order to prevent sideways rattle, and they can be purchased at DIY stores. Tubular vinyl weather-stripping is another option, but it is prone to tear, and can affect the appearance of a window.

When installing replacement sash runners It is crucial to take full measurements of the window opening. It is recommended to take measurements from the top of the sash up to the horizontal centerline of 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 ensure a proper fit and a better performance of the window.

In older buildings the gap between the frame and sash is typically larger around the leading edge. It can be draught proofed by a self-adhesive V-strip, but it is crucial to take this into consideration when measuring and cutting the material.

The strip should be cut at the top of the sash and with an inch added on each side to allow movement. The strip should be cut square and positioned so that the ends are matched to the angle of the window sill. Use stainless steel screws since brass will rust. Also, use high-quality polyurethane or silicone glue.

Refurbishment

The sash is a beautiful, historical feature of many homes. These windows are gorgeous however they are susceptible to problems. Common problems include rattling, stuck or draughty windows. Also, rotting frames, meeting rails, broken glass bars, or damaged weights could cause a lot of trouble. When these issues arise, it's time for a sash repair or replacement.

Refurbishment may be more expensive than replacing the sash, but can bring back the appearance and function to the same standard that it was in its original form. It involves re-lining the meeting rail and sash box with traditional putty and fixing any rot damage. Re-painting the frame of the timber is also included, as is 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). Finally, it's recommended to install brush pile weather strips in order to minimize rattle and increase insulation.


If the need for a new sash arises, it can be made using similar designs to the old frame and maintain the character of your house. This is especially crucial for listed buildings, where any modifications to windows require planning permission.

Compare the metal tabs on the new window to the old sash prior installing it (see below). If they're different shapes and sizes, the new sash will not fit into the window frame slots.

If a window has been damaged, it's essential to choose between repair or replacement since each kind of repair will involve a different level of expertise and cost. For example when a sash window has a large chunk of glass that is missing, then replacing it is the best choice. However when the glass is damaged in one small section or a sill has been damaged, a repair would be the better option.

Replacement

While a lot of homeowners are eager to keep their old sash windows in good working condition, the deterioration of the windows can cause problems such as rattles, draughts or even broken glass. This is why it's often the only solution to these issues. There are other ways to improve sash window performance than simply replacing them. These include installing secondary glazing and draughtproofing.

Take note of the severity of the issue. It may not be necessary or suitable to replace the window. A glass that is foggy, for example is typically caused by the sash, and can be resolved without tearing out the entire frame. It is typically possible to fix a weak seal by making a few easy fixes, rather than tearing out the entire frame and replacing it.

Sash windows are surprisingly complex in design and have many moving parts. This is why it can be tricky to remedy some common problems like sash cords that are snapped or broken panes. Resolving these issues often requires dismantling the window frame, which isn't a job the majority of homeowners would like to tackle themselves. Many homeowners choose to engage a professional for these reasons.

Specialists can restore sash window frames to their original splendor or update them to meet the latest energy standards. This could include reconditioning the frames and installing secondary glazing, which will stop heat escaping out of the window. You can also install an edge strip for brush-piles to cut down on drafts and prevent the window from squealing.

To begin the repair, take off the window stops. (The moldings that are located in front of the lower glass). Next, loosen the staff bead, then pull out the lower sash. Remove the cords and chains from both sides. Finally, remove the sashweights from the bottom of the cavity for weight. Keep the hardware in a secure location. Soften any old filler or hardened putty with a heat gun and scrape it off with the help of a putty knife. Reassemble the window. Reattach the hardware. Lubricate the pulleys by using Teflon or silicone spray. Reinstall the parting bead, and put back the upper sash.

Repair

It is essential for the homeowner to decide whether to repair or replace their sash windows. Although modern replacements offer a host of benefits but the original features of an older home add personality and value to the property and are usually cheaper to repair than replacing them. Keeping them in good condition will also help you save money on energy. Sash windows are vulnerable to rattles, drafts, and condensation. These problems can lead to increased energy bills and damage to the frame and the sash.

Sash windows can be a challenge to open or close. The mechanism for sliding could become dislodged or draughty. Repairing a sash window requires extensive removal of the frame of the window and should be left to professionals. With the right tools and knowledge, it is possible to repair an old sash window yourself. Adam shows Jess the basics:

Getting the window to come apart begins by removing any security fittings that are in front of the lower sash. Then, remove the staff bead and pull out the bottom sash. Take the chains and cords from both sides, and tie them in a way that they can't be pulled back by the attached weights. It's now time to remove the upper sash. The sash stops must be removed and a thin strip of wood that holds the sash. Also, remove any paint-encrusted hardware. The sash should be pulled back to reveal the weight. It is a large iron or lead cylinder that is concealed in a cavity, and held by cords. To prevent the sash from falling into the void make a hole in it using nails and remove the weight.

After the sashes are removed clean the jambs as well as the rails that meet. Remove the glazing bars and sash cords. Then, using a utility blade take off any paint that is on the sash stop. Reattach the stops after the sashes are reinstalled. Use nails that are small enough not to puncture the balancing weight.

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