Sash Windows Repair and Replacement

Sash windows that are older than 20 years may have a variety of problems that include rattles and draughts. They may also be poorly constructed to be insulated. A little attention can often bring them back to a top level of performance.

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

Sealing

Sash windows look gorgeous in old buildings but they require regular maintenance and can be subject to issues like cracks in putty, wet rot, and drafts. Repair, sealing, or replacement of the windows in sash is a great way to reduce these problems and increase energy efficiency.

Draughts are mostly caused by gaps between the sash and frame. They can also lead to noise reduction and rattle. Various methods can be used to stop air leaks from the sash window, such as sealing beads, special products, and secondary glazing.

A gap between the top and bottom of the sash, and the jamb frame, is an issue that is common. This can result in water leaking into the wood, rotting of the wood and growth of mould. Seal the gap using silicone, polyurethane or foam sealant.

Installing a new sash runner, or spring bronze could be required in the event that a gap blocks windows from opening and home shutting effortlessly. These are a type of bronze that are stapled or nailed into the edges of the lower sash in order to prevent sideways rattle. They can be purchased from DIY stores. Tubular vinyl weather-stripping is an alternative option but it can tear, and can make a difference to the appearance of a window.

It is essential to determine the size of the window opening prior to installing the an alternative sash runner. It is best to measure from the top of the sash up to the horizontal centerline on the meeting rail and from the bottom sash down to the sill. These measurements can later be transferred to new runners that will ensure the best fit and function of the window.

In older buildings the gap between frame and sash is typically wider around the leading edge. It is possible to draught proof with a strip of self-adhesive V-strips, but it is important to account for this when cutting and measuring the material.

The strip should be cut to the height of the sash and with an inch extra on each side to allow movement. It should be cut to a square shape and then positioned so that the ends are aligned to the angle of the window sill. Use stainless steel screws since brass can be rusty. Also, make sure to use a high 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 range of issues. Draughts, rattling, sticking or leaks are all common problems. Rotting frames and meeting rails as well as broken glazing bars, damaged frames, or rotten weights can cause issues. If you experience any of these issues, it is time to replace or repair your sash.

Refurbishment can be more expensive than replacing the sash, but can bring back the appearance and function to the same level that it was in its original form. Refurbishment involves lining the meeting rail as well as the sash box using traditional putty and fixing any damage caused by the rot. It also involves re-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). Finally, it's recommended to fit brush pile weather strips in order to minimize the rattling and increase insulation.

If a new sash is needed it can be constructed using the same style to match your old frame. This will help preserve the style and character of your home. This is particularly important for buildings that are listed, as any modifications to windows will require planning permission.

Check the metal tabs of the new window with those of the old sash prior to installing it (see below). If they're different shapes, the new sash won't fit in the window frame slots.

It's important to decide whether to repair or replace a damaged window, as each option will require a different level and amount of knowledge. For example the case of a sash windows that has a large piece of glass missing then replacement is the best option. However, if the glass has been damaged in a tiny section or a sill is decaying, a repair may be the better option.

Replacement

Although many homeowners want to keep their old sash windows in good working condition, deterioration could eventually cause issues such as draughts, rattles, or even broken glass. This is why replacing them is often the only option to solve these issues. However, there are other ways to improve sash windows, beyond simply replacing them, including installing draught proofing as well as secondary glazing.

It's important to consider the severity of a problem, as it may not be practical to replace an entire window. For instance, a foggy glass issue is usually a problem within the sash itself and can usually be solved without ripping out the whole frame. A poor seal can also often be corrected by a few easy fixes rather than an expensive full-frame tear-out and replacement.

Sash windows feature a complicated design that has many moving parts. It can be difficult to fix common problems like broken panes or snapped sash cables. Most homeowners don't want to take apart the window frame in order to fix the issues. Because of this, many opt to hire an expert.

Specialists can restore sash window frames back to their original splendor or make them more up-to-date with modern energy standards. This can include reconditioning frames and fitting secondary glass to prevent heat from escaping through the window. It is also possible to add an extra strip of brush pile to stop the rattling and decrease drafts.

To begin a repair, remove the window stops. (The moldings are in front of the lower glass). Next, loosen the staff bead, then remove the lower sash. Remove the cords or chains on both sides. Finally, remove the sash weights and the bottom of the weight cavity and remove them. Keep the hardware in a secure location. Soften any old filler, hardened putty, or filler with a heat gun and scrape it away using the help of a putty knife. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray. Install the parting beads and install the upper sash.

Repair

Although modern replacements offer many advantages, the original features of an older home give personality and value to the property and are generally less expensive to repair than replacing them. Keeping them in good condition will also help you save money on energy. Sash windows are susceptible to drafts, rattles, and condensation, and these problems can lead to increased cost of energy and damage to the frame and sash.

Making the window come apart begins by removing any security fittings on the front of the lower sash. Then, you can remove the staff bead. Finally, pull out the sash at the bottom. Remove the chains and cords from both sides, and tie them in such a way that they won't be pulled back by the weights attached. It's now time to take out the upper sash. Take out the sash stops which is a thin vertical strip of wood that is used to hold the sash. Also, 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 hidden in a cavity and is supported by a cord. To stop the sash from falling into the void, pierce it with a nail and then let the weight go.

After the sashes have been removed clean the jambs as well as the rails that meet. Remove the glazing bars as well as the cords of the sash. Then using a utility knife, remove any paint from the sash stop. Reattach the stops when the sashes are reinstalled. Use nails that are not large enough 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 stoppers are aligned properly with the frame, and then reattach the parting beads if needed. Reattach the sash cords or chains and then install the sash pulleys.
