Sash Window Repair

Sash windows can go out of balance and even break. Pam searches the internet for salvaged waving glass, wavy and is always looking for the sash weights that are discarded, made of metal. She then seeks replacements, such as washers or nuts to help balance her window.

Pam puts each pane in with a rope of glazing compound she uses to create the rabbet groove, or pocket, which is located around the opening. This reduces drafts and prevent costly heat loss.

Sashes that stick Sashes

It's a nightmare when double-hung windows get stuck. You'll lose your view when they squeak in a storm. On the other hand, a window that's too loose will allow external air and noise through and your energy bills could increase. Neither scenario is optimal, but both can be fixed with the proper tools and perseverance.

Paint can build up on the channels of old weighted window tracks, causing them to jam. Luckily, most issues with this can be solved by cleaning and lubricating the tracks.

Begin by removing the old caulking between the window stop (the internal one) and the window frame. Scrape off any paint that has built up. Make sure you employ a sharp blade and then set up sheets of plastic and a vacuum cleaner right below to catch any paint dust and chips.

You can then clean the tracks using a dry cloth, and apply an oil based on silicone to make them more gliding. It is available in most home improvement stores, or on the internet. You can test it by moving the sash either upwards or downwards.

If it still jams, there could be a problem with the sash cord. Examine the sash cord to determine if the cord is caught or hanging from the sash, or if it has snapped completely. You'll have to re-cord your window in the event of this.

A pin that keeps the rail in place may have lost its grip. It isn't easy to fix and you'll require the help of an expert most of the time.

Make use of a wood hardener if the wood is swollen and warped, but there's not a pin. The liquid is quick drying and can restore damaged wood. You won't have to remove the windows on your sash to repair them. After using it, you can pry off the two sashes by placing a piece of wood on the lower corner of the window where they meet.

Draughts

Draughts can be a major issue for windows with sash windows that are old particularly during winter months. They can be caused by decayed wood, broken putty or worn cords for sash. This can allow cold air to get inside the window, making it more difficult to heat your home. You can reduce the risk of drafts by filling the gaps with expanding foam, or using draught-excluding strips available at most hardware shops. These are effective, but they'll have to be replaced from time to time because the foam expands and wears away with use.

A more permanent option is Gapseal, which is a spongy rubbbery seal that you can cut to the desired size and then insert into the gaps between the sash window frame. It can be used by itself or in conjunction with adhesive strips at the top and bottom. This option is expensive and you'll need to apply it several times over the course of the life of your window. However, it's a long-term fix and is easy to remove.

Cling film can also be used to stop drafts. Simply scrunch it up and then insert it into the gaps around your window. This is a great draught-stopper, but it can also hinder the sash's movement and possibly cause fire. Furthermore the sash needs to be removed to re-open the door and the cling film will need to be applied every time you close the sash.

As part of a comprehensive renovation you can have your window draught-proofed. This could include the installation of new sash strings, parting beads and staff beads in addition to the lubrication and rebalancing the weights, lubrication and rebalancing the pulley wheel. It may also include staining or painting the frames and sashes. This will restore the sash to its original function, improve its energy efficiency and correct any minor flaws in the timber. It is less disruptive than removing the windows, and can reduce draughts, improve the thermal efficiency and dramatically reduce costs.

Decay

The good news is that your windows' sash frames aren't in need of repair if they've been damaged or decayed. The frames of these windows are generally made of high-quality timber. If you can restore them properly they can be repaired to provide high performance for many years to come. Regular inspections are essential in ensuring that the wood is adequately ventilated. This will stop moisture build-up that can cause wood decay.

The majority of the issues you'll encounter with sash windows will be easily visible on a close examination, however certain issues are more difficult to identify. Wood decay is particularly difficult to fix, as fungus can eat the wood. It is possible to fix wood that is rotten, however, the best method to avoid further decay is to ensure that the timber is dry.

First, clean any paint from the hardware. It is possible to remove the bottom rail from the frame and the rail for meeting (this will depend on the location of the sash). You'll then have to remove the "pocket covers" which are pieces of wood on the side of the frame that are low down that give access to the weights (the parting beads run down the middle of them). They can be fixed by nailing them in place and then securing them with paint, so you'll likely require a knife to cut them out of the way. Once the pockets have been removed, you can start chiseling out any wood rot and apply a high-quality, water-resistant filler. After the filler has dried, the primer must be applied to guard against further decay.

It is a good idea to inspect inside the window the sashweights to ensure they are in balance. They shouldn't be displaced, or pulling one side more strongly than the other. The sash may slide off the track if they aren't balanced. This could cause the frame to crack or become damaged. You can replace the sashweights with new ones or install an entirely new balance system to prevent the sash from swinging in the wrong way.

Poor Security

Over time sash windows are exposed to the elements and susceptible to deterioration from weather and general wear. In time, this may result in wood decay that in turn will need to be replaced, costly repair that needs to be dealt with as soon as possible. The signs of decaying wood can be seen by water marks beneath the window, or the frame becoming soft to touch. It is important to consult an expert to assess the situation and determine if sash window repairs are necessary.

Similarly, over time the rails on the bottom can become damaged. The sill may show water marks or a window that is soft to the touch may be an indication of this. A professional will be required to examine the situation and recommend any repair of sash windows or replacement.

It can be very concerning when triple or double windows are glazed and start to allow noise pollution back into the home. If this happens, the structural integrity of sash windows may be in danger and is likely to need to be replaced with a different option.

A common issue with repairing sashes is when the sash becomes stuck in the frame. This can be caused by a snapped cord or problems with sash ratchets. If the problem is related to the sash rats, a bit of gentle persuasion will usually work.

Removing the sash from the frame and cleaning the tracks of dust or dirt can often aid in resolving this issue. Once the tracks are clean remove any security fittings that may be present, and then removal of the sash cords as well as chains will allow the sash be removed. The staff bead may be sealed with an draught-proof seal in order to minimize the possibility of draughts. This can also improve the finish of paint. The gap between the box and the sash could be filled with decorators caulk in order to improve the operation of the sash and lessen draughts.
