Sash Windows Repair and Replacement
Sash windows older than 20 years may have a variety of problems such as rattles and draughts. They might also be poorly insulated. With a little care they can be restored to a high level of performance.
First, remove the paint seal using an utility knife. Then remove the staff bead, then pull out the upper sash, taking off chains or cords and storing the hardware in a labeled bag.
Sealing
Sash windows are gorgeous in older buildings, 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 method to minimize these issues and improve the efficiency of energy.
The gaps between the sash and frame are the primary cause of drafts. They can also cause noise and rattling, which can reduce soundproofing. There are a variety of methods to stop air leaks from a sash window, including sealing beads, specialty products and secondary glazing.
A common problem is a gap that exists between the top of the sash and the jamb frame, or between the bottom of the sill and the sash. This can cause moisture to leak in, rotting wood and growth of mold. The gap can be closed with silicone or polyurethane caulking or foam sealant.
If a gap is preventing the windows from closing and opening without a hitch, it might be necessary to replace spring bronze or sash runners. These are a type of bronze that are stapled or nailed into the edges of the lower sash to stop sideways rattle, and they can be purchased from DIY stores. Tubular weatherstripping also can be used, however it tends to rip and can alter the appearance of your window.
It is important to measure the entire window opening before installing new sash runners. It is recommended to take measurements from the top of the sash to the horizontal centerline of the meeting rail, and from the bottom of the sash 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 greater around the leading edge. It is possible to draught-proof it using strips of V-strip that is self-adhesive. However, it is important to take this into account when measuring and cutting material.
A strip must be cut to the length of the sash, and with an additional inch each side to allow to allow for movement. It should be trimmed squarely and positioned in accordance with the angle of the sill. It is also important to make use of stainless steel screws as brass can rust, and high-quality polyurethane or silicone adhesive.
Refurbishment
The sash is an attractive historical feature of a lot of homes. These windows are beautiful, but they can be susceptible to problems. Draughts, rattling or leaks are all common problems. The rotted frames and the meeting rails as well as broken glazing bars, faulty frames, or rotten weights can cause issues. 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, however, it can restore the look and function of your sash window to the same or better than the original condition. It involves lining the joining rail and sash box using traditional putty and repairing any rot-related damage. It also 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). In addition, it is recommended to put in brush pile weather strips to lessen rattling and improve insulation.
If a new sash is required the frame can be constructed using similar designs to the frame of the previous one and preserve your property's heritage style. This is especially important for buildings that are listed, as any changes to the windows will require planning permission.
Before you put the new window on before installing it, make sure you examine its metal tabs with those on the old sash (see below). If they're different sizes, the new sash will not fit inside the window frame slots.
If a window has been damaged, it's essential to choose between repair or replacement since each kind of repair will require a different degree of expertise and price. For example when a sash window has a large piece of glass that is missing, then replacement is the best option. If the glass is damaged in a small area or a sill has begun to decay and needs to be repaired, then a repair will be more appropriate.

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 pull the lower window sash. Remove the chains or cords on both sides. Then, remove the sashweights from the bottom of the cavity for weight. Keep the hardware in a safe position. Soften any old filler or hardened putty with a heat gun and scrape it off with a knife for putty. Reassemble the window, attach the hardware and lubricate pulley axles with silicone or Teflon spray.

It is best to leave the repair of window with sash to a specialist, as it requires extensive removal. However, with the right tools and experience it is possible to repair old sash windows yourself. Adam shows Jess how to start:
Making the window come apart starts with the removal of any security fittings on the front of the lower sash. Next, remove the staff bead, then take the sash off the bottom. Remove the chains and cords from both sides, and tie them so that they cannot be pulled back by the weights. It's time to take off the upper sash. Unscrew the sash stops (a thin vertical strip of wood that is used to hold the sash) and then loosen any paint-encrusted hardware. Pull the sash back to reveal the weight. It is a large iron or lead cylinder, which is tucked away in a cavity, and secured by an elastic cord. To prevent the sash falling into the void, you must pierce it using a nail, and sacrifice the weight.
After the sashes have been removed clean the jambs as well as the rails that meet. Remove the glazing bars and sash cords. Then employing a utility blade take off any paint from the sash stop. Reattach the stops when the sashes have been put back in place. Use nails that are small enough not to puncture the weight of the balancing.
To reassemble the sash, put the top sash into its track first, then the lower sash. Make sure that the sash stops are properly aligned with the frame, and then reconnect the beads that separate if required. Reattach the sash chains or cords and install the sash pulleys.
