Sealing
Sash windows are beautiful in older structures, but they require maintenance. They are susceptible to issues like wet-rot, cracked putty and draughts. Repair, sealing, or replacement of the windows sash is an effective method to minimize these issues and increase energy efficiency.
Draughts are mainly caused by gaps between the sash and the frame. They can also cause rattles and reduce sound-proofing. There are a variety of methods to limit air leaks within windows with sash, including sealing beads, special products and secondary glazing.
A gap between the top and bottom of the sash, and the jamb frame, is a common problem. This can cause water leaking into the wood the wood, rotting and growth of mould. The gap can be filled by caulking made of silicone or polyurethane or foam sealant.
If a gap in the window is preventing windows from closing and opening easily, it could be necessary to put in new spring bronze or sash runners. These bronze strips are attached by staples or nails to the lower sash edges to stop the rattling of the sides. They can be purchased at DIY stores. Tubular vinyl weather-stripping is another option however it can rip, and it can detract from the appearance of windows.
When installing replacement runners for sash, it is important to take full measurements of the window opening. It is recommended to take measurements from the top of the sash to the horizontal centerline of the rails that meet, and from the bottom of the sash to the sill. These measurements can be transferred to the new runners, which will ensure a proper fitting and better operation of the window.
In older buildings there is a greater gap between the sash and the frame at the leading edge. It can be draught-proofed by using a strip of V-strip which is self-adhesive. However, it is important to take this into account when measuring and cutting material.
The strip should be cut at the top of the sash with an inch more on each side to allow movement. It should be cut square and placed in a way that the ends are aligned to the angle of the window sill. Use stainless steel screws since brass can get rusty. Also, make sure you use a high quality polyurethane or silicone glue.
Refurbishment
The sash window is an elegant, historic feature of many homes. These windows are beautiful however they are susceptible to problems. Rattling, draughts, sticking or leaking are typical issues. The rotted frames and the rails that connect them, as along with broken glazing bars, faulty weights or rotten frames can cause issues.

Refurbishment is a more expensive option than simply replacing the sash itself but it will bring back the appearance and function of your sash window to as good if not better than its original state. It involves lining the joining rail and sash boxes with traditional putty and fixing any rot-related damage. It also involves 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 fit brush pile weather strips in order to minimize rattling and improve insulation.
If you require a new sash, it can be made from like-for-like designs to match the frame that was previously used and keep the style of your home's historic design. This is particularly important for listed buildings where any changes to the windows need planning permission.
Compare the metal tabs of the new window to the old sash prior to installing it (see below). If they're different shapes, the new sash will not fit inside the window frame slots.
It is crucial to determine whether to repair or replace windows that are damaged, as each will require a different level and cost of knowledge. For instance the case of a sash windows that has a large chunk of glass missing then replacing it is the best option. However in the event that the glass is damaged in one small section or a sill is damaged, a repair would be the better option.
Replacement

These issues often suggest replacement as the only feasible solution. There are other options to improve sash window performance other than replacing them. These include the installation of secondary glazing and draught-proofing.
Consider the extent of the problem. It may not be necessary or even necessary to replace windows. Foggy glass for instance is typically caused by the sash, and can be addressed without having to tear out the entire frame. It is often possible to fix a weak seal by making a few easy solutions, rather than cutting out the entire frame and reinstalling it.
Sash windows are quite complex in design and feature a lot of moving parts. It can be a challenge to fix common problems such as broken panes, or sash cables that have snapped. The solution to these issues typically involves dismantling the window frame, which isn't something most homeowners would want to take on themselves. Many homeowners decide to hire a specialist for these reasons.
A specialist can help restore windows made of sash to their original splendor or even bring them up to modern energy standards. This could include reconditioning the frames and fitting secondary glazing to stop heat from the window. It is also possible to add an edge strip for brush-piles to cut down on drafts and stop the window from shaking.
To begin the repair, take off the window stops. (The moldings that are in front of the lower glass). Then, loosen the staff bead and take off the lower sash. Remove the cords and chains from both sides. Finally, remove the sash weights from bottom of the cavity and take them off. Store the hardware in a safe place. Soften any old, hardened putty or filler with a heat gun and scrape it away using the help of a putty knife. Reassemble the window, attach the hardware and lubricate the pulley axles using silicone or Teflon spray. Reinstall the parting beads and then reinstall the upper sash.
Repair
The choice of replacing or repairing a sash window is a major one for the homeowner. Modern replacements offer many advantages however, the original features of an older house can add the character and value. They are also less expensive to repair rather than replace.

Sash windows are notoriously difficult to close and open, and the traditional sliding mechanism can become dislodged from its track or become draughty. Repairing a sash window involves extensive dismantling of the frame of the window and should be left to professionals. With the right tools and experience, it is possible to fix old sash windows yourself. Adam shows Jess the basics:
The process of bringing the window apart starts with the removal of any security fittings in front of the lower sash. Then, you can remove the staff bead. Then, remove 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 that are attached. It's time to take off the upper sash. Unscrew the sash stops (a thin vertical strip of wood that holds the sash) and remove any painted-covered hardware. Pull the sash back to reveal the weight. It is a large iron or lead cylinder that is hidden in a cavity, and supported by a cord. To prevent the sash from falling into the void, hit it with an hammer and then sacrifice the weight.
Once the sashes are free, clean out the jamb and meet rails, remove the glazing bars and sash cords, and remove any paint off the sash stops with a utility knife. When the sashes are returned to their original positions, you can attach the stops using nails that are small enough to prevent cutting the balancing weight.
Reassemble the sash by inserting the upper sash first on its track, then the lower sash. Make sure that the sash stops are aligned properly with the frame, and then reattach the beads for parting if necessary. Reattach the sash cords or chains and attach the sash pulleys.
