Sash Window Repair
Sash windows can become severely damaged from age and neglect. While cosmetic damage is likely to need to be repaired however, functional issues with a window such as rattles and draughts suggest that the window's repair is in order.
First steam the sash to loosen it. Then remove the wood pegs using the help of a pin punch and hammer. Note down all the components to ensure that they can be replaced correctly in the future.
Wood that is broken or rotten
If left unattended, rotting wood can cause damage to the brickwork around windows and cause damage to plaster. The good thing is that a lot of the time, this issue can be fixed without having to replace the window altogether.
The first thing to be taken care of is to ensure that the wood in the issue is dry. Examine the colour and grain of the wood to see whether it's dry. If the wood is brittle and brown, it means that it's very likely rot has already begun to develop. Check if the sash's position is secured by a few spliced pieces of timber and if they aren't damp.
Another common issue is moisture trapped in the corners of frames of sash. This can cause the sash to become stuck and difficult to open. The solution is to clean the sash channels and eliminate any blockage with a sharp wood chisel. Once the sash channel has been cleared free of obstructions it can be primed to prevent future damp problems.
It's also important to examine the wood used in constructing the window frame. It is recommended to choose timber that is the same color and grain pattern as the existing pieces of wood otherwise it could be difficult to join the joins. You might also want to consider using a wood preservative, which will aid in keeping the wood in good shape and prevent the wood from rotting.
If the wood in your sash windows is severely damaged and rotten, it may be wise to consider replacing it completely. It is essential to select an alternative window that is that is the same style as the windows you have in place to ensure that they appear as nice once they are installed. Choosing UPVC over timber for instance, may lower the value of your house as prospective buyers might think you are going against period design.
Insecure Sash Hardware
A sash window is made to move effortlessly, however often wood rot, as well as other problems can affect its functionality. A poorly functioning window may also lead to drafts in the home, and also the loss of energy efficiency. The longer you leave a sash window unattended and it wears out faster. This could reduce its lifespan significantly and may lead to moisture or water infiltration.
It can be frustrating to try and determine the cause of a sash-window issue. In many cases replacing the sash may be the solution. Whether the issue is caused by rotting timber, a misalignment or imbalance of the sash or broken glass replacement of one or both windows could help to solve the problem.
Replacing a single window sash is less expensive than replacing the entire frame and glass. It is also simpler than installing a brand new double-hung window, which requires the removal of a larger amount of trim and parts. You can start by examining your existing window and frame if you wish to replace the sash. You might notice gaps or issues that could cause the sash to tilt and prevent it from staying up.
In the majority of cases, it is possible to repair the double-hung sash by removing the trim and working from the inside of the frame. It is best to first take off the stopper in the interior of the sash which creates a track in the window at the bottom. To accomplish this spray a hose with water and lightly mist the inside the stop, then pull it out using a utility knife. Then, using a razor blade, you can cut off any nails that are protruding through the the stop's interior.
After removing the sash and frame to look for an access panel for weights, which is a knockout inside the frame that's big enough to pass a sash weight through. If yours does not have one, you can create a new hole by cutting an elongated rectangle from the vinyl jamb liner to the height of the stile.
Sash that isn't working properly weighs
The two weights that pull the sash upwards and down can become disconnected from each other as time passes, resulting in the sash becoming jammed, or stuck in an open position. This is caused by worn out or broken cords for sash that must be replaced.
During this repair job it is important to lay dust sheets wherever possible to prevent any debris or dirt from settling on your carpet or furniture. This is especially important if you plan on lifting and moving the window during work, to avoid damaging any area of your home.
Start by carefully removing each bead from the frame on either side with a small, broad chisel. You will notice an incline running along each side of the sash. It will eventually end with the knot hole in which the new sash cord will be placed. Make window repair to remove any knots in the old cord that are screwed or nailed into the hole.
Now it's time to begin replacing the sash cords starting with the top sash. To do this, gently lower the sash up until it hits the bottom sill and support it by placing a wedge on either side of the frame. Otherwise, it may drop to the floor and break the glass - a problem you definitely want to avoid!
Then, you can remove the access panel from the frame to retrieve the sash cord and sash weight. Once you have the sash weight, remove the dado from the wood's edge and insert the nail to fix it. Make sure to use a nail that's long enough to reach the sash pocket otherwise it won't fit.
Once you have the weight in place, you can then replace the sash cord by feeding it into the hole. Then, push the sash upwards onto the rails and down into the window box. check the way it opens and closes and then add more lubrication to the rails if required (we recommend candle wax for wood, or silicone spray for vinyl).
If you're replacing both cords ensure that they're identical in length to the old ones were, so when you release one from its pin it will fall easily through the sash, settling at the pulley, and then function normally. After the sash has been re-hung you can then reconnect the stop beads and your sash is complete!
Glass that is damaged
A broom, a baseball or a stone that is thrown by a lawnmower can cause enough damage to the glass. Such shattered glass will allow water, snow, rain and even insects to enter your home. In some cases the damage caused by shattered glass might require a complete window replacement. However, replacing windows can be a major expense home improvement project. In most cases, replacing broken windows can be a much more manageable and less costly option.
Before attempting to install new glass, it is important to make sure you carefully examine the sash. This is an opportunity to identify any previously hidden spots in which the wood is beginning to decay or where the old weather stripping, glue and hardware have become damaged. This test will save you time and money in the near future.
After the glass has been removed it's recommended to give the wood a good coat of homemade wood preservative. Mix equal parts mineral spirit and linseed to create the wood preservative. Apply the mixture with a putty knife to the sash's surface and let it dry completely. This will ensure that your brand new glass and sash is water-resistant and lasts for a long time.
If the sash is in good condition, you can fix it without removing the glass. The first step is to remove the window stop which is a vertical piece of wood that is placed over the stiles of the window frame. The stop is typically fixed by a small pry bar, which is atop a stiff-bladed knife. After the stop has been removed, it is possible to separate the rail and stiles by using a soft-faced mallet or woodworking hammer to avoid damaging the profile of the sash. The next step is to take off the muntins which are the vertical and horizontal pieces of wood that divide the glass panes in the sash.
Once the muntins are removed, it's simple to replace the glass that has been broken. Use glazing compound to hold the metal tabs in their slots on the sash.
