Sash Windows Repair and Replacement
Older sash windows may be plagued by a variety of issues, including draughts rattles and poor insulation. A little bit of care can often restore them to a high standard of performance.
First, cut off the seal of paint using an utility knife. Then remove the staff bead, then pull out the upper sash, taking off chains or cords, and then storing the hardware in a bag marked.
Sealing
Sash windows are beautiful in older structures, but they require regular maintenance. They can be affected by problems like wet-rot cracked putty, and draughts. It is possible to minimize 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 primary source of drafts. They can also trigger rattles and reduce sound-proofing. Sealing beads, specialist products, and secondary glazing can all be used to minimize the air leakage inside the Sash.
A common problem is a gap between the top of the sash and the jamb frame, or between the bottom of the sash and the sill. This could cause moisture to leak into the wood, rotting it and the growth of mold. Seal the gap using silicone, polyurethane or foam sealant.
If a gap in the window is preventing the windows from closing and opening easily, it could be necessary to replace spring bronze or sash runners. These strips of bronze are attached by staples or nails to the lower sash edges in order to stop the rattling of the sides. They are available at DIY stores. Tubular vinyl weather-stripping is an alternative option but it has a tendency to rip, and it can affect the appearance of windows.
It is important to take measurements of the entire window opening prior to installing a new sash runners. It is recommended to measure from the top of the sash up to the horizontal centerline of the rail of the meeting and from the bottom sash down to the sill. These measurements can later be transferred to new runners that will ensure a better fit and operation of the window.
In older structures the gap between sash and frame is usually wider around the leading edge. It can be draught-proofed by using strips of V-strip that is self-adhesive. However it is crucial to consider this when measuring and cutting material.
The strip should be cut at the height of the sash, with an inch more on each side to allow movement. It should be cut squarely and positioned to match the angle of the sill. It is also important to use stainless steel screws since brass can rust and a high-quality polyurethane or silicone adhesive.
Refurbishment
The sash is an attractive, historical feature of many homes. They are beautiful but they can also be prone to problems. Common problems include rattling, stuck or draughty windows. Rotting frames and meeting rails as and broken glazing bars, faulty frames, or rotten weights can cause issues. If you are experiencing any of these issues it's time to replace or repair your sash.
Refurbishment can be a more costly option than simply replacing the sash itself, but it can restore the look and function of your sash window to the same or better than the original condition. It involves re-lining the meeting rail and sash box with traditional putty and fixing any rot-related damage. It also involves 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's also recommended to install brush pile weather strip to reduce the noise of rattling.
If you require a new sash it can be constructed from similar designs to the old frame and maintain the style of your home's historic design. This is especially crucial for listed homes where any modifications made to the windows will require planning permission.
Before putting the new window in place, it's best to check the metal tabs against those on the sash that was previously used (see below). If the tabs are different shapes, the new sash will not fit correctly into the window frame slots.
If a window has been damaged, it is crucial to decide between repair or replacement since each kind of repair will require a different degree of expertise and price. For example, if a sash window has a large piece of glass missing then a replacement will be the best option. However, if the glass is damaged in a small area or a sill is rotting then a repair will be more appropriate.

Specialists can restore sash window frames back to their original splendor or make them more up-to-date with the latest energy standards. This can include reconditioning frames and fitting secondary glass to block heat from getting out of the window. You can also add a brush-pile strip to reduce drafts and stop the window from squealing.
To begin a repair, remove the window stops (the moldings on the front of the lower sash). Then you can loosen the staff, and pull out the lower window sash. Take off the cords or chains on both sides. Finally take the sashweights out of the bottom cavity of the weight. Keep the hardware in a secure location. Heat gun to soften the old, hardened filler or putty. Scrape it away with the blade of a putty.

Getting the window to come apart begins with the removal of any security fittings on the front of the lower sash. Then, you can remove the staff bead. Finally, pull out the bottom sash. Then, pull out the chains or cords on both sides and tie the ends to stop them from being pulled back into the frame by the attached weights. Now it's time to remove the upper sash. Take out the sash stops which is a thin vertical wood strip that holds the sash. Also, remove any paint-encrusted hardware. Unscrew the sash to reveal the balancing weight, that is a massive iron cylinder or lead that is enclosed in a concealed cavity and anchored by a rope. To prevent the sash from falling into the void, hit it with nails and remove the weight.
After the sashes are removed clean the jambs as well as meet rails. Remove the glazing bars and cords of the sash. Then using a utility knife take off any paint from the sash stop. When the sashes are back in place, you can reattach the stops using nails that are small enough to prevent damaging the weight that is balancing.
Reassemble the sash by putting the upper sash first into its track, then the lower sash. Make sure that the sash stops and the frame are properly aligned. If necessary, reattach any beads used for parting. Then, reconnect the sash chains or cords and then re-attach the axles for the sash pulleys.
