How to Repair Timber Windows
To ensure that the windows remain functional and free from swelling and decay, they require regular maintenance. Untreated and poorly maintained sash windows may suffer from rattling, sticking, and draughts.
Check for rotted areas on the window frame. If the rot is extensive it may be worth replacing the entire frame.
Verify the condition
Wooden windows are an important part of many homes, providing an attractive natural aesthetic as well as lots of security. They can be susceptible to damage and deterioration. The condition of wood window frames, as well as sashes should be inspected periodically to ensure they function in the way they were intended to.
Rot is one of the most frequent issues that window frames made of wood face. Wood rot can be caused by excessive exposure to water, which can cause timber to become spongy and soft. The good news is that the rot can be dealt with patience and effort.
The first step to evaluate the condition of your timber windows is to check for any signs of damage or rot, such as cracks or loose parts. Examine the weather stripping of windows to make sure that they are properly sealed and prevent water infiltration.
It's important to test for softness in the event that you spot any signs of rotting. You can do this by pressing them down with an instrument like a screwdriver, or your finger. Healthy, solid wood will be able to withstand this pressure. Rotting wood will easily break down. If the rot is more than 10%, it's better to replace the frame instead of try to fix it.
After the timber sections that have been damaged have been treated, sanding them down is the next step. It's best to start with a coarse-grit sandpaper before moving on to finer grits until your repaired area is smooth and blends seamlessly into the remainder of the window. After sanding, the area is primed and painted to ensure that the repair is not visible to the naked eye.
In some cases when the rotting is extensive and the timber is weak enough to be repaired, it could be necessary to have a lintel inserted above the window. It is structural support beam that helps support the weight of walls above the cavity in which the timber frames are placed. A structural engineer could install an lintel in order to prevent decay and decay of old timber windows.
Take the Glass off
It is easier to deal with the broken glass when you take the frame and window. This makes the task much easier. Wear gloves and a towel to shield your hands from the sharp shards. If you end up saving a few fragments, make sure to wrap them in newspaper and dispose of them in a safe manner.
After removing the glass you must inspect the condition of the wood. It's a good idea use a sponge or damp cloth to clean the frame or sash as well as any vents that you may have installed in your windows. You can begin to get rid of the dirt and grime if there is plenty. It is important to avoid putting solvents or chemicals in the frame and sash as this could cause damage.
If you notice any indications of rust or corrosion on the hardware then it is recommended to take off and replace the damaged part. This will improve the appearance and functionality of your window, and also prevent the windows from jamming and squeaking.
Check that the frames and hinges are in good shape and that they can are able to move freely and that there is no visible decay on the frames. If the hinges or sashes become difficult to open or close then it's typically a sign that they're worn or out of adjustment and require adjustments.
A lot of timber window problems are the result of weather and moisture. Moisture uptake can create local stress at the exposed glued joint which could result in them opening and let in moisture. The staining of moisture can be the result too.
Modern timbers like Accoya or Red Grandis are more resistant to damage than standard woods. It is worth asking your joinery provider which types of kinds of timbers they have available. It is crucial to select the right type of wood since different kinds of wood expand and contract at different speeds. Selecting the wrong type could cause damage and reduce the lifespan of your timber windows.
Remove the old Putty
Windows made of wood are an indisputable characteristic of many older buildings and, if properly examined and repaired, they will look beautiful and serve their important functions such as letting light in and preventing rain from entering, as well as providing good insulation. Timber frames can rot when they are not maintained. If this happens, the strength of the windows can be damaged and replacement could be necessary.
The first step is to examine the condition and the quality of the frame as well as the glazing putty. This is the material that is used to hold the glass panes in the wooden sash. It might not be possible for large portions of wood to be saved, but they can be cut and treated to keep the remainder of the window functional.
If you decide to repair the sash the next step is to take it from its carrying. Set it on a flat surface similar to an employee. It is a good idea to remove the handle and seals at this point as well so that you can inspect their condition.
There are many products that can be mixed with raw linseed oil in order to loosen old putty. The mixture is applied generously to the old putty, and let it sit for fifteen or twenty minutes before scraping it off with a razor blade or chisel. This process should be repeated several times in order to remove all the old putty.
Having removed the old putty, it is important to make sure that the frame and window are thoroughly cleaned to stop moisture from entering. This could include sanding down and stripping paint layers with strippers made of gel, or cutting out rotten sections of timber before splicing new ones. If a splice is required, then it should be treated and painted with a sealant to avoid further damage.
Once all the old putty has been removed, it is time to apply fresh glazing putty on the window. It is best to use a good quality oil-based linseed, since it will be easier for you to sand. It will also give the window a nice, smooth finish. It is a good tip to roll out a small amount putty and form a sausage shape before applying it to the frame of the window. This will make it easier to apply the putty, and look more neat once it is in place.
Reattaching the Glass
Wooden windows are a long term investment for your home, and should be maintained regularly. If you do not take care of them for a long time the frames will begin to rot and affect the structure, security, and insulation of your house. But, rather than replacing the entire window, it is more economical to repair them.
If a pane of broken glass is found and it is repaired by using the appropriate size glass. The old glass must first be removed and the new glass placed in. It is easier to do this if your window is removed from its casing it can be clamped down on a work surface with the caulked side of the window facing windows repair up, or put into a window frame that's been opened and then shut.
The sash is fixed by a glue or (typically in older windows made of timber) panel pins. When repairing an old historic window it's important to use materials that are similar in appearance so the repairs don't stick out as a sore thumb. The majority of modern caulks aren't suitable for homes with historical architecture and should be avoided.
It is also essential to ensure there aren't any traces of putty or paint left in the rabbet grooves that the glass is set in the sash windows; they will block the glass from fitting correctly. Also, ensure that there is no debris in the frame or around the frame that could cause a leak.
You can apply a piece of clear tape or concealing tape over the crack to secure it. This will also stop any water from entering the gap. Glass adhesives made of solvents can be used to fill and hold the cracked glass in place if it is at risk of falling off from the sash.
If the casing and sash are in good condition and draughts are not a problem, they can be fixed by cleaning, lubricating and painting. If you're not confident in performing these simple tasks, a professional joiner who specialises in overhauling wooden windows may be able help.
