How to Repair Timber Windows To ensure that windows made of timber remain functional and free from swelling and rotting they require regular maintenance. Sash windows that aren't treated or poorly maintained can be prone to rattling and sticking. The first step is to search for rotted areas of the window frame. If the rot is severe, it might be worth replacing the entire frame. Check the condition Windows made of wood are an essential part of many homes, providing an appealing natural look and a great deal of security. However, they are susceptible to damage and deterioration, and the condition of timber windows and sashes must be checked on a regular basis to ensure that they are still functioning as intended. One of the most significant issues facing timber window frames is the rot. Wood is susceptible to rot due to excessive exposure to water, which can cause timber to become spongy and soft. The good news is that it is possible to treat the rot and have the wood restored to its original condition with some effort and perseverance. The first step to evaluate the condition of your wood windows is to check for any signs of damage or rot, such as cracks or loose parts. It's also worth checking the weather stripping that is on the windows to make sure that they're properly sealed and preventing water infiltration. If double glazed window repairs spot any areas of rotting it is crucial to check for softness. You can test this by pressing them down with a screwdriver, or even your finger. Solid, healthy wood can withstand this pressure, while rotting wood will give way easily. If the rot is greater than 10%, it's best to replace the frame instead of try to fix it. After the damaged sections of timber have been treated by sanding them down, the next step. Begin with coarse-grit papers, then move to finer grits. This will ensure that the repaired area blends seamlessly into the remainder of the window. After sanding it is possible to prime it and then painted to make the repair invisible. In certain instances where the rotting is severe and the timber is weak enough to be repaired, it could be necessary to install an lintel placed above the window. It is a structural beam designed to support the weight of the walls over the cavities where the timber frames sit. The lintel installation can be done by a structural engineer, and is a great way to avoid the degrading of wooden windows in older buildings. Remove the Glass It's easier to deal with the broken glass when you remove the frame from the window. This makes the job simpler. You'll want to guard yourself from sharp shards by wearing gloves and using a towel when wiggling out each piece of glass. If you do end up saving a few fragments, make sure to wrap them in newspaper and dispose of them carefully. After you've removed the glass, you can check out the condition of the wood. Use a damp sponge or a cloth to clean your window frame, sash, and any vents. You can begin to get rid of the grime and dirt when there's lots. It's important to make sure that you don't introduce any chemicals or solvents into the frame or sash since this can cause damage. If you see any signs of corrosion or rust on the hardware, it is recommended to take off and replace the damaged parts. This will improve the appearance and functionality of your window, and also prevent the window from jamming and squeaking. Verify that the hinges and sashes are in good working order, that they are able to move freely and that there's no visible decay on the frames. If the hinges or sashes become difficult to open or close, it's usually a sign that they're worn or out of adjustment and require readjusting. A majority of window issues are caused by the weather and moisture. The uptake of moisture can cause local stress at the exposed glued joint which could result in them opening and allowing moisture into the frame. This could also cause the staining of moisture. Thankfully, modern timbers such as Accoya and Red Grandis can withstand a lot more damage than traditional timbers which is why it's a good idea to check with your preferred joinery company to see which timber they can offer. It's important to get the correct timber, as different woods expand and contract at different rates, so choosing the wrong one could lead to the damage and a shorter time for your new windows made of timber. Removing the old Putty Wooden windows are a typical feature in older buildings. They can be repaired to make them look beautiful and serve their purpose in letting light in, blocking out rain and providing insulation. The frames of timber can begin to rot if they are neglected. When this happens, the strength of the windows is damaged and replacement could be necessary. The first step is to examine the condition and quality of the frame as well as the glazing putty. It is the material that is used to hold the glass panes in the wooden sash. If large sections of timber are severely damaged, it may not be viable to save them, but they are often connected and then treated to ensure that the remainder of the window remains functional. If you decide to repair the sash, the next step is to take it from its holder. Set it on a flat surface similar to a workmate. You may also want to remove the seals and handle at this point so that you can inspect them. There are a variety of products that can be mixed with linseed oil to loosen old putty. The mixture is applied generously to the old putty, and left to settle for about 15 or 20 minutes before scraping it off with a razor blade or chisel. This process must be repeated several times in order to remove all of the old putty. After you have removed the old putty, it is recommended that you need to thoroughly clean your window and frame to prevent moisture from getting into. This might include sanding down or stripping paint layers using strippers that are gel-like or cutting off rotten pieces of timber before splicing new ones. If a splice is required then it should be treated and coated with a protective paint in order to prevent further damage. After all the old putty has been removed, it is now time to apply some fresh glazing putty to the window. A high-quality linseed oil putty is recommended because it will be easier to sand and provide an attractive finish to the window. It is a good idea to roll out a small amount putty into a sausage shape before applying it to the frame of the window. This will make it easier to apply the putty and look neater once in place. Reattaching the Glass Wooden windows are a long-term investment for your home and should be maintained regularly. If you neglect them for a long time the frames will begin to decay and impact the structure, security and insulation of your house. Repairing your window is usually cheaper than replacing it. In the case of a broken pane of glass, the sash window can be repaired by removing the broken glass, then filling it with new glass and re-glazing it with the correct size of the new glass. This is easier to do if you remove the window from its casing. It can then be clamped on an object with the caulked side of the window facing upwards, or put into a frame that has been opened and secured again. The sash is held in place by putting it on with putty or (in older timber windows), panel pins. It's important to choose materials that resemble those used when repairing an older historic window. This will make the repairs blend into the existing decor and not make a statement. Most modern caulks are not suitable for historic homes and should be avoided. It is also important to ensure that there aren't any remnants of putty or paint left in the rabbet grooves that the glass sits in the sash window; they will block the glass from sizing properly. Also, make sure there isn't any debris in the sash window or around the frame that could lead to leaks. You can put a piece of clear tape or concealing tape over the crack in order to keep it in place. This will also stop any water from entering the crack. Glass adhesives made of solvents can also be used to fill and keep the glass in place when it is in danger of becoming detached from the sash. If the sash and casing are in good condition, then draughts can be eliminated through cleaning, lubricating and painting. If you're not confident in performing these simple tasks, a specialist joiner who is skilled in overhauling wooden windows may be able to help.
