Sash Windows Repair and Replacement

Older sash windows suffer from a range of issues, including draughts rattles, and poor insulation. With a little attention they can be repaired to a higher level of performance.

First, knock off the paint seal from the window stop using a utility knife. Remove the staff bead, then pull out the upper sash and remove any cords or chains. Store the hardware in a bag that has a label.

Sealing

Sash windows are beautiful in older structures, but they require regular maintenance. They are susceptible to problems like wet-rot cracked putty, and draughts. It is possible to minimize energy loss and increase the efficiency of windows with sash by replacing them, repairing or sealing them.

Draughts are usually caused by gaps between the sash and frame. They can also lead to rattles and reduce sound-proofing. Sealing beads, special products and secondary glazing can be used to limit the air leakage within a shutter.


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

Installing a new sash runner or spring bronze could be necessary in the event that a gap blocks the windows from closing and opening effortlessly. These are bronze strips that are stapled or nailed to the edges of the lower sash to prevent sideways rattle. They can be purchased from DIY stores. Tubular vinyl weather-stripping is an alternative option, but it has a tendency to rip, and it can make a difference to the appearance of windows.

When installing replacement sash runners, it is important to measure the window opening. It is recommended to measure from the top of the sash to the horizontal centerline of the rails that meet and from the bottom of the sash to the sill. These measurements can be incorporated into the new runners, which will help ensure a perfect fitting and better operation of the window.

In older structures there is a larger 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 material.

The strip should be cut at the top of the sash, with an inch extra on each side to allow movement. It should be cut squarely and placed to match the angle of the sill. Use stainless steel screws since brass may get rusty. Also, make sure you use the highest quality silicone or polyurethane glue.

Refurbishment

The sash is a beautiful, historical feature of many homes. However, despite their beauty these windows are prone to a variety of problems. The most frequent issues are rattling, stickiness or draughts. Also, rotting frames, connecting rails, broken glazing bars or weights that are not working properly can cause a lot of trouble. If these issues occur, it's time for repairs or replacements to your sash.

Refurbishment may be more expensive than replacing the sash but can restore the appearance and function to the same standard that it was in its original form. Refurbishment involves lining the meeting rail as well as the sash box with traditional putty, and then repairing any damage caused by rot. Re-painting of the timber frame 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). It is also recommended to put in brush pile weather strips to reduce the rattling and increase insulation.

If a new sash is required it can be constructed using the same design to match the frame you have. This will preserve the traditional style of your property. This is particularly important for buildings that are listed, as any changes to the windows will require planning permission.

Check the metal tabs of the new window with the old sash prior to installing it (see below). If they're different sizes and sizes, the new sash will not fit inside the slots of the window frame.

If a window has been damaged, it is essential to decide between replacement or repair, because each kind of work will require a different level of expertise and cost. If a large part of the glass in a sash is missing replacing it would be an option. If the glass is only damaged in a tiny area or a sill has begun to decay and needs to be repaired, then a repair will be better.

Replacement

Many homeowners want to keep their old sash windows in good condition, however the deterioration of the window will eventually cause issues like 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 the sash windows that go beyond replacing them, like installing draughtproofing and secondary glazing.

It's important to consider the severity of a issue, as it may not be feasible to replace a complete window. For instance, a fogging glass issue is usually a problem within the sash and can usually be solved without ripping out the whole frame. It is typically possible to fix a weak seal with a few simple fixes, rather than tearing out the entire frame and reinstalling it.

Sash windows are extremely complicated in their design and come with a lot of moving parts. It can be challenging to fix common problems like cracked panes or snapped sash cable. The solution to these issues typically involves removal of the window frame which isn't something most homeowners want to take on themselves. Because of this, many opt to hire a specialist.

A professional can help restore windows made of sash to their original splendor, or even bring them up to current energy standards. This can include reconditioning the frames and installing secondary glazing, which will stop heat through the window. It may also be beneficial to put in a brush pile strip, to stop rattling, and reduce drafts.

To begin a repair take out the window stops (the moldings on the front of the lower sash). Next, loosen the staff bead, then remove the lower sash. Remove the chains or cords on both sides. Lastly, remove the sashweights from the bottom weight cavity. Store the equipment in a secure place. Use a heat gun to soften old, hardened filler or putty. Scrape it off using a putty blade. Reassemble check , reattach the hardware and then lubricate the pulley axles by using silicone or Teflon spray. Reinstall the parting beads and then reinstall the upper sash.

Repair

It is crucial for homeowners to decide whether to repair or replace their sash windows. Modern replacements are beneficial in many ways however, the original features in an older home can add the character and value. They are also cheaper to repair rather than replace.

Sash windows can be a challenge to open and close. The mechanism for sliding could become sloppy or draughty. It is best to leave the repair of a window with sash to a specialist since it requires a lot of removal. With the right tools and experience it's possible to fix an the old sash window yourself. Adam shows Jess how to begin:

Getting the window to come apart begins with the removal of any security fittings that are in front of the lower sash. Then, remove the staff bead. Then, take out 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 attached weights. It's now time to remove the upper sash. Unscrew the sash stoppers (a thin vertical strip of wood that is used to hold the sash) and then loosen any paint-encrusted hardware. The sash can be pulled back to reveal the weight balancing, which is a large iron cylinder or lead that is enclosed in a concealed cavity and held by a rope. To prevent the sash falling into the void pierce it with a nail and then let the weight go.

After the sashes have been removed, clean the jambs and the rails that meet. Remove the glazing bars and sash cords. Then, using a utility blade take off any paint from the sash stop. Once the sashes are back in place, you can reattach the stops using nails that are small enough to avoid cutting the weight that is balancing.

To reassemble the sash, place the top sash on its track first, and then the lower sash. Check that the sash stops and the frame are aligned correctly. If necessary, reattach any beads that are parting. Finally, reattach the sash chains or cords and re-attach the axles of the sash pulleys.
