Sash Windows Repair and Replacement
Sash windows that are older than 20 years old can be afflicted with various issues that include rattles and draughts. They may also be poorly insulated. With a little attention they can be restored to a higher level of performance.
First, scrape off the paint seal from the window stop with the knife of a utility. Then, take off the staff bead and remove the upper sash, taking off chains or cords, and then storing the equipment in a bag labeled.
Sealing
Sash windows are beautiful in older buildings, but they require maintenance and can be subject to problems like cracked putty, wet rot and drafts. It is possible to minimize energy loss and increase the efficiency of sash windows by replacing, repairing or sealing them.
The gaps between the sash and frame are the primary cause of drafts. They can also cause noise and rattling, which can reduce soundproofing. Sealing beads, specialty products and secondary glazing can all be used to minimize the air leakage in the shutter.
A common problem is a gap between the top of the sash and the jamb frame or between the bottom of sill and the sash. This can lead to the leaking of moisture the wood, rotting and growth of mould. The gap can be closed with caulking made of polyurethane or silicone or foam sealant.
Installing new sash runner or spring bronze might be necessary if a gap prevents windows from closing and opening smoothly. These bronze strips are tied or stapled to the lower sash edges to prevent the rattling of the sides. They can be bought at DIY stores. Tubular vinyl weather-stripping is an alternative option, but it can rip, and it can detract from the appearance of a window.
It is essential to measure the entire window opening prior to installing a an alternative sash runner. It is best to measure from the top of sash up to the horizontal line on the rail that connects them and from the bottom sash down to the sill. Enfield window repairs can be transferred to the new runners, which will help ensure a good fitting and better operation of the window.
In older buildings, the gap between frame and sash is typically greater 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 the material.
A strip should be cut to the length of the sash, and with an additional inch on each side to allow for movement. The strip should be cut square and placed in a way that the ends are matched to the angle of the window sill. Use stainless steel screws since brass may get rusty. Also, make sure to use high-quality silicone or polyurethane glue.
Refurbishment
The sash is a stunning, historical feature of many homes. But despite their beauty, windows like sash windows can be prone to a range of issues. Common issues include rattling draughts or sticking. Also, rotting frames, meeting rails, broken glazing bars, or damaged weights could cause a lot of trouble. When these problems occur it's time for a sash repair or replacement.
Refurbishment can be a more costly alternative than replacing the sash itself, but it will improve the appearance and functionality of your sash window as good if not better than the original condition. Refurbishment involves lining the meeting rail as well as the sash box with traditional putty, and repairing any damage caused by the rot. Re-painting of the timber frame 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). Finally, it's recommended to put in brush pile weather strips in order to minimize the rattling and increase insulation.
If a replacement sash required, it can be made with the same design to match your old frame. This will help preserve the traditional style of your property. This is especially important for listed buildings where any modifications made to windows will require planning permission.

It's important to decide whether to replace or repair a damaged window, as each choice will require a different degree and amount of expertise. If a large portion of the glass in a sash is missing, replacing it would be a better option. If the glass is only damaged in a small area or a sill is beginning to rot and needs to be repaired, then a repair will be more appropriate.
Replacement

Take note of the severity of the problem. It may not be necessary or suitable to replace the window. For instance, a fogging glass issue is usually a problem in the sash itself and is typically a solution without tearing 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.

This may include reconditioning frames and installing secondary glazing, to avoid heat escaping through the window. It is also possible to add a brush-pile strip to reduce drafts and prevent the window from shaking.
To start a repair project, remove the window stops (the moldings on the front of the lower sash). Then you can loosen the staff, and pull the lower window sash. Take off the chains or cords that are on both sides. Finally, disconnect the sash weights from the bottom of the weight cavity and remove them. Keep the hardware in a safe place. The heat gun will soften hardened filler or putty. Scrape it off with the blade of a putty. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray.

Unscrew the sash stops (a thin vertical strip of wood that is used to hold the sash) and remove any paint-encrusted hardware. The sash should be pulled back to reveal the weight. It is a large iron or lead cylinder, which is tucked away in a cavity and is secured by an elastic cord. To keep the sash from falling into the void, hit it with nails and remove the weight.
After the sashes have been removed Clean the jamb and meet rails. remove the glazing cords and sash bars, and scrape off any paint off the sash stops using the help of a utility knife.
