Sash Windows Repair and Replacement
Older sash windows can suffer from a range of problems including draughts, rattles, and inadequate insulation. With a little attention they can be repaired to a higher level of performance.
First, take off the seal with a utility knife. Remove the staff bead, pull out the upper sash, and take off any chains or cords. Store the hardware in a container with a label.
Sealing
Sash windows are beautiful in older structures, but they require care. They can be affected by issues such as wet-rot, cracked putty, and draughts. Repair, sealing or replacement of the windows sash is an effective way to reduce these problems and improve the efficiency of energy.
The gaps between sash and frame are the main source of draughts. They can also lead to noise reduction and rattle. Sealing beads, specialist products and secondary glazing can all be used to minimize the air leakage within the Sash.
A common issue is a gap that exists 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 growth of mold. The gap can be closed with silicone or polyurethane caulking or foam sealant.
If a gap is preventing windows from opening and closing easily, it could be necessary to put in new sash runners or spring bronze. These are strips of bronze that are stapled or nailed into the edges of the lower sash to prevent sideways rattle. They are available from DIY stores. Tubular vinyl weather-stripping is an alternative option however it can tear and make a difference to the appearance of windows.
When replacing sash runners it is essential to measure the window opening. It is best to take measurements from the top of the sash up to the horizontal centerline of the rail that connects it, and from the bottom of the sash to the sill. These measurements can then be transferred to new runners that will ensure the best fit and function of the window.
In older structures, the gap between sash and frame is usually larger around the leading edge. It can be draught-proofed using a strip of V-strip that is self-adhesive. However, it is important to take this into account when measuring and cutting material.
A piece of material should be cut to the length of the sash. There should be an extra inch 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. Make sure to use stainless steel screws since brass will rust. Also, make sure to use high-quality silicone or polyurethane glue.
Refurbishment
The sash is an attractive historic feature in many homes. They are beautiful, but they can be susceptible to issues. The most frequent issues are rattling, stuck or draughty windows. The rotting of frames and meeting rails, broken glazing bars, or damaged weights could cause a lot of trouble. When these issues arise, it's time to consider a sash repair or replacement.
Refurbishment is more costly than replacing the sash but can restore your sash's look 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 fixing any damage caused by rot. window repairs includes re-painting the frame of timber 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). It is also recommended to install brush pile weather strips to reduce rattling and improve insulation.
If a replacement sash required it can be constructed with the same design to match your old frame. This will help preserve the style and character of your house. This is especially crucial for listed homes where any modifications made to windows will require planning permission.
Before putting the new window on before installing it, make sure you compare its metal tabs to those on the sash that was previously used (see below). If these are different shapes the new sash won't fit properly into the slots of the window frame.
It's important to decide whether to repair or replace a damaged window, as each option will require a different degree and amount of knowledge. If a large portion of the glass in a sash is missing, replacing it would be a better alternative. However when the glass is damaged in a small area or a sill has been rotting then a repair will be the better option.
Replacement
While a lot of homeowners are eager to keep their old sash windows in good working condition, deterioration could eventually cause problems such as rattles, draughts, or even broken glass. This is why it's often the only solution to these problems. However, there are ways to improve the sash windows beyond just replacing them, including installing draughtproofing and secondary glazing.
It's important to consider the severity of the issue, as it may not be appropriate or even practical to replace an entire window. Foggy glass, for example, is usually caused by the sash and can be addressed without having to tear out the entire frame. A leaky seal can be fixed by a few easy fixes instead of a costly full-frame tear-out and replacement.
Sash windows are extremely complex in design and feature many moving parts. It can be a challenge to fix some common problems like broken panes or sash cables that have snapped. Many homeowners do not want to remove the window frame in order to fix these problems. This is why many homeowners choose to work with a specialist.
Specialists can restore sash window frames to their original glory or update them to meet the latest energy standards. This could include reconditioning the frames and fitting secondary glazing, to avoid heat loss out of the window. You can also add a brush-pile strip in order to minimize drafts and prevent the window from rattling.
To begin a repair project start by removing the window stops (the moldings that are in front of the lower sash). Then, loosen the staff and remove the lower window sash. Remove the cords or chains on both sides. Then remove the sashweights from the bottom cavity of the weight. Keep the hardware in a safe position. Heat gun to soften the old, hardened filler or putty. Scrape it off with the blade of a putty. Reassemble the window, reattach the hardware and then lubricate the pulley axles using silicone or Teflon spray. Reinstall the parting beads and reinstall the upper part of the sash.
Repair
The choice to replace or repair the sash window is a major one for the homeowner. Modern replacements are beneficial in many ways however, the original features of an older home can add character and value. They are also cheaper to repair instead of replacing. Maintaining them in good condition can also reduce the energy cost. Sash windows are vulnerable to drafts, rattles, and condensation, and these problems can result in increased cost of energy and damage to the frame and sash.
Sash windows are notoriously difficult to close and open, and the traditional sliding mechanism can become dislodged from its track or draughty. Repairing a sash window requires extensive dismantling of the frame of the window and should be left to the professionals. With the right tools and skills, it is possible for you to repair old sash window yourself. Adam shows Jess the basics:
Getting the window to come apart starts by removing any security fittings on the front of the lower sash. Then, remove the staff bead. Then, take out the bottom sash. Remove the cords and chains from both sides, and knot them in such a way that they won't be pulled back by the attached weights. It's now time to remove the upper sash. Take out the sash stops, a thin vertical strip of wood that holds the sash. Also, take off any painted-covered hardware. Unscrew the sash to reveal the balancing weight, which is a large iron cylinder that is encased inside a hidden compartment and anchored by rope. To prevent the sash falling into the void, pierce it using a nail, and then let the weight go.
After the sashes are removed, clean the jambs and the rails that meet. Remove the glazing bars and the sash cords. Then using a utility knife take off any paint that is on the sash stop. When the sashes are returned to their original positions, you can attach the stops using nails that are small enough to prevent cutting the weight that is balancing.
Reassemble the sash by placing the upper sash first on its track, followed by the lower sash. Make sure the sash stops are aligned properly with the frame, and then reattach the beads for parting if necessary. Reattach the sash chains or cords and install the sash pulleys.
