Sash Windows Repair and Replacement

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

First, remove the seal of paint using an utility knife. Then remove the staff bead and pull out the upper sash and remove the chains or cords and storing the hardware in a labeled bag.

Sealing

Sash windows are beautiful in older buildings, but they require maintenance and can be subject to problems like cracks in putty, wet rot and draughts. Repair, sealing or replacement of the sash window is an effective method to minimize these issues and improve energy efficiency.

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

A common issue is a gap that exists between the top of the sash and the jamb frame or between the bottom of sill and the sash. This can lead to moisture leaking in, rotting wood and growth of mold. Seal the gap using silicone, polyurethane or foam sealant.

If a gap in the window is preventing windows from closing and opening smoothly, it may be necessary to put in new spring bronze or sash runners. These strips of bronze are stapled or nailed to the lower sash edges to prevent sideways rattling. They can be purchased at DIY stores. Tubular vinyl weather-stripping is another option however it has a tendency to rip, and it can make a difference to the appearance of a window.

It is crucial to take measurements of the entire window opening prior to installing the new sash runners. It is best to take measurements from the top of sash up to the horizontal centerline of the meeting rail 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 as well as the frame around the leading edge. It is possible to draught proof by a self-adhesive Vstrip, however it is important to account for this when measuring and cutting the material.

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

Refurbishment

The windows with sash are a stunning, historic feature of many homes. They are beautiful, but they can be susceptible to problems. Draughts, rattling, sticking or leaking are typical issues. The rotting of frames and connecting rails, broken glazing bars or weights that are not working properly can cause a lot of trouble. When these problems occur it's time to consider repairs or replacements to your sash.

Refurbishment can be more expensive than replacing the sash but it will restore your sash's look and function to the same level in its original condition. Refurbishment involves re-lining both the meeting rail and the sash box with traditional putty and fixing any damage caused by rot. Re-painting the frame of the timber is also included, as is the re-glazing process 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 in order to minimize rattling and improve insulation.

If a replacement sash is needed it can be constructed using the same design to match your existing frame. This will help preserve the style and character of your house. This is especially important for buildings that are listed, as any changes to the windows need planning permission.

Before putting window repair near me in place, it's best to check the metal tabs against those on the old sash (see below). If these are different shapes the new sash won't fit properly into 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 involve a different level of expertise and expense. For example, if a sash window has a large chunk of glass that is missing, then replacement is the best option. If the glass is only damaged in a small region or a sill is rotting, then a repair would be better.

Replacement

Many homeowners would like to keep their old sash windows in good shape, but the deterioration of the window will eventually cause issues like rattles or draughts. Broken glass is also a possibility to occur. This is why it's often the only solution to these problems. There are other methods to improve sash window performance rather than replacing them. This includes the installation of secondary glazing and draught-proofing.

Think about the scope of the problem. It may not be necessary or suitable to replace a window. A foggy glass problem for instance, is usually caused by the sash and can be fixed without tearing out the entire frame. It is often possible to fix a weak seal by making a few easy solutions, rather than cutting out the entire frame and replacing it.

Sash windows are quite complicated in their design and come with many moving parts. It can be a challenge to fix common issues like cracked panes or sash cables that have snapped. The solution to these issues typically involves removal of the window frame which isn't a job most homeowners want to tackle themselves. This is why many homeowners choose to work with a specialist.

A specialist can help restore sash windows to their original splendor, or even bring them up to the latest energy standards. This may include reconditioning frames and fitting secondary glazing, which will stop heat through the window. It is also possible to add a brush-pile strip in order to minimize drafts and prevent the window from squealing.

To begin a repair, take off the window stops. (The moldings that are located in front of the lower glass). Then, loosen the staff bead, then pull out the lower sash. Remove the cords and chains from both sides. Finally, remove the sash weights from bottom of the cavity and take them off. Place the hardware in a safe location. Use a heat gun to soften hardened filler or putty. Scrape it off with the blade of a putty. Reassemble the window. Reattach the hardware. Lubricate the pulleys using Teflon or silicone spray. Reinstall the parting bead, and put back the upper sash.

Repair

It is crucial for homeowners to make a choice on whether to repair or replace their sash windows. Modern replacements are beneficial in many ways however, the original features in an older home can provide authenticity and value. They are also less expensive to repair than replacing. Inspecting them regularly can reduce the energy cost. Sash windows are vulnerable to rattles, drafts and condensation. These problems can result in increased costs for energy and damage to the frame and the sash.

Sash windows are notoriously difficult to open and close as the traditional sliding mechanism can be displaced from its track or become draughty. It's best to leave the repair of a window sash to a professional, as it requires extensive dismantling. With the right tools and knowledge, it is possible to repair an the sash window that is old. Adam shows Jess how to get started:

Making the window come apart begins by removing any security fittings that are in front of the lower sash. Next, take off the staff bead, then take the sash off the bottom. Then, take the cords or chains on both sides and tie the ends to stop them from being pulled back into the frame by the weights attached to them. The next step is to remove the upper sash. Remove the sash stops (a thin vertical strip of wood that is used to hold the sash) and remove any painted-covered hardware. The sash should be pulled back to reveal the weight. It is a large iron or lead cylinder that is concealed inside a cavity and secured by cords. To stop the sash falling into the void hit it with a nail and sacrifice the weight.

Once the sashes are free clean the jamb and rails that meet, remove the glazing bars and sash cords, and strip any paint from the sash stops using the help of a utility knife. Reattach the stops when the sashes are reinstalled. Use nails that are not large enough to damage the balancing weight.

To reassemble the sash place the top sash on its track first, then the lower sash. Make sure that the sash stops are aligned properly with the frame, and then reattach the parting beads if needed. Then, reconnect the sash chains or cords and re-install the axles for the sash pulleys.
