Sealing

Sash windows can look stunning in old buildings but they require regular maintenance and are susceptible to issues such as cracks in putty, wet rot, and draughts. It is possible to reduce energy loss and increase the efficiency of windows made of sash by replacing the windows, repairing or sealing them.

The gaps between the sash and frame are the main source of drafts. They can also trigger rattles and reduce sound-proofing. Sealing beads, specialty products, and secondary glazing can all be used to minimize the air leakage inside the shutter.

A gap between the top or bottom of the sash and the jamb frame is a common problem. This can cause moisture leaking in, rotting of the wood and growth of mould. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.

Installing a new sash runner, or spring bronze might be necessary if a gap prevents windows from closing and opening easily. These are a type of bronze that are stapled or nailed to the edges of the lower sash to stop sideways rattle, and they are available at DIY stores. Tubular weatherstripping also can be used, but it is prone to tear and can alter the appearance of your window.

When replacing sash runners, it is important to measure the window opening. It is recommended to take measurements from the top of the 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 ensure a proper fit and a better performance of the window.

In older structures, there is a wider gap between the sash as well as the frame at the leading edge. It can be draught-proofed by a self-adhesive Vstrip, however it is essential to account for this when cutting and measuring the material.

A strip should be cut to the length of the sash, with an additional inch on each side to allow movement. It should be trimmed squarely and placed in accordance with the angle of the sill. It is also crucial to use stainless steel screws because brass is prone to rust, and high-quality silicone or polyurethane adhesive.

Refurbishment

The sash is a stunning historic feature in many homes. However, despite their beauty these windows are susceptible to a variety of problems. Draughts, rattling, sticking or leaks are all common problems. The rotted frames and the rails that connect them, as and broken glazing bars, defective weights or rotten frames can all cause problems. If these issues occur, it's time to consider a sash repair or replacement.

Refurbishment is more costly than replacing the sash but can bring back the appearance and functionality to the same level that it was in its original form. Refurbishment involves lining both the meeting rail and the sash box using traditional putty, and then repairing any damage caused by rot. It also involves re-painting the frame with timber and reglazing 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 put in brush pile weather strip to reduce the noise of rattling.

If a replacement sash required, it can be made using the same design to match your existing frame. This will help preserve the style and character of your house. This is particularly crucial for listed buildings, where any changes to the windows require planning permission.

Compare the metal tabs on the new window to the old sash prior to installing it (see below). If these are different shapes the new sash won't fit in the slots of the window frame.

It's important to decide whether to replace or repair windows that are damaged, as each choice will require a different degree and level of expertise. If a large part of the glass in a sash is missing, replacing it would be a better option. But in the event that the glass has been damaged in a small area or a sill is decaying, a repair may be the better option.

Replacement

While many homeowners are keen to keep their old sash windows in good working condition, deterioration could eventually cause problems such as rattles, draughts or even broken glass. These issues typically suggest replacement as the only logical solution. There are other options to improve sash window performance than simply replacing them. This includes installing secondary glazing and draught-proofing.

Consider the extent of the problem. It may not be necessary or suitable to replace windows. A glass that is foggy for instance, is usually caused by the sash, and can be resolved without tearing out the entire frame. A poor seal can also often be remedied by making a few minor adjustments instead of a costly full-frame tear-out and replacement.


Sash windows are a complicated design with many moving parts. This is why it can be a challenge to remedy some common problems, like snapped sash cords or broken panes.

Specialists can restore sash window frames to their original glory or update them to meet modern energy standards.

You can also install a brush-pile strip in order to minimize drafts and stop the window from squealing.

To start a repair project start by removing the window stops (the moldings in front of the lower sash). Next, remove the staff bead and pull out the lower sash. Remove the cords and chains from both sides. Lastly take the sashweights out of the bottom cavity of the weight. Keep the hardware in a secure place. The heat gun will soften hardened filler or putty. Scrape it off with the blade of a putty. Reassemble the window, reconnect the hardware and lubricate pulley axles using silicone or Teflon spray. Reinstall the parting bead and reinstall upper sash.

Repair

It is crucial for homeowners to decide whether to repair or replace their sash windows. Although modern replacements can provide many advantages but the original features of an older home add authenticity and value to the home and are usually cheaper to fix than replacing them.

Sash windows can be difficult to open and close. The mechanism for sliding could become dislodged or draughty. Repairing window repairs near me requires extensive removal of the frame of the window, so it's best left to professionals. With the right tools and know-how it's possible to fix old sash windows yourself. Adam shows Jess how to get started:

Remove any security fittings that are behind the lower window sash. Then, remove the staff bead, then pull out the bottom sash. Then, remove the chains or cords on both sides and tie them to stop them from being pulled back into the frame by the weights attached to them. The next step is to take out the upper sash. The sash stops must be removed, a thin vertical wood strip that holds the sash. Also, remove any painted-covered hardware. The sash can be pulled back to reveal the weight balancing, which is a large iron cylinder that is encased in a concealed cavity and secured by rope. To prevent the sash from falling into the void, pierce it with a nail and sacrifice the weight.

After the sashes have been removed, clean the jambs and rails that connect them. Remove the glazing bars and cords for the sash. Then employing a utility blade take off any paint that is on the sash stop. Reattach the stops after the sashes have been put back in place. Use nails that are small enough not to puncture the balancing weight.

Reassemble the sash by inserting the upper sash first on its track, 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 cords or chains and attach the sash pulleys.
