Verify the Condition

Wooden windows are a beautiful addition to any home. They offer a natural aesthetic and a high security level. However, they are susceptible to deterioration and damage, and the condition of timber window frames and sashes should be regularly assessed to ensure that they function in the way they were designed to.

Rot is one of the most frequent problems window frames made of wood face. Wood rot can be caused by excessive water exposure which can cause wood to soften and spongy. The good news is that decay can be treated and the wood restored to its original condition with a little effort and perseverance.

To assess the condition of timber windows It is important to first look for signs of damage such as cracks and loose parts. Check the weather stripping of the windows to ensure they are properly sealed to prevent water infiltration.


If you see any rotting areas it is crucial to test them for softness. This can be done by pressing down on the wood with a screwdriver or your finger. Healthy, solid wood will be able resist this pressure. Wood that is rotting will quickly fall apart. It is important to keep in mind that in the event that the rot has gotten to a greater than 10 percent of the frame it's better to replace it rather than making repairs.

After the damaged portions of the timber have been treated, it's time to remove them from the wood. It is best to begin with a sandpaper of coarse-grit and then move to finer grits until your repaired section is smooth and blends seamlessly into the rest of the window. After sanding the area, it can be primed and then painted, so that the repair is not visible to the naked eye.

In some instances, if decay has been extensive and the wood is not strong enough to be repaired, it might be necessary to have a lintel be placed above the windows. It is a structural beam designed to support the weight of the walls above the cavities where the frames of timber sit. A structural engineer can install a lintel to prevent the decay and decay of older timber windows.

Remove the Glass

If a window is damaged, it is recommended to remove the frame and work on that, rather than working around the glass. This makes the job much simpler. You'll want to shield yourself from sharp shreds by wearing gloves as well as using a towel to wipe out every piece of glass. If you decide to save a few pieces of glass, wrap them in newspapers and dispose of them with care.

After removing the glass you must inspect the condition of the wood. It's recommended to use a damp sponge or cloth to wipe down the frame, sash and any vents you might have inserted into your windows. You can begin to get rid of the dirt and grime if there is a lot.

Make sure that the hinges and sashes are in good condition and that they can move freely, and that there is no visible rot on the frames. If the hinges or sashes are difficult to open or close, then it's typically a sign that they're worn out or out of adjustment and need adjustment.

A lot of timber window problems are caused by weather and moisture. Moisture uptake can create local stress at the joint that is exposed to the gluing, which can cause them to open and let in moisture. Staining from moisture could be a result of this too.

Modern timbers like Accoya or Red Grandis are more resistant to damage than standard woods. It is a good idea to ask your joinery provider which types of timbers they offer. It's crucial to choose the right timber as different woods expand and contract at different rates, so selecting the wrong type of wood could cause damage and a shorter span for your new windows made of timber.

Take off the old Putty

Windows made of wood are a common feature in older structures. They can be restored to make them look beautiful and serve their purpose in letting light in, blocking out rain and providing insulation. glass window repair can become rotten when they are not maintained. Once this happens, the integrity of the windows is compromised, and replacement may be required.

The first thing that needs to be taken care of is to check the condition of the frame and glazing putty (the substance which holds glass panes in the wooden sash). If large sections of timber are severely damaged, it may not be feasible to save them, however they can be spliced in and treated to ensure that the rest of the window remains functional.

If you decide to go by making repairs, the next step is to unhook the sash from its holder and place it on a flat surface like a workmate. It is recommended to remove the handle and seals at this point, so that you can check their condition.

There are many different products that can be used to loosen and eliminate old putty. One of the best is to make use of a little of Household Chlorine Bleach mixed with raw Linseed Oil. It is then applied liberally to the old putty, and allowed to sit for about 15 or 20 minutes before scraping the surface with a razor blade or chisel. It is typically necessary to repeat this procedure several times to completely remove the old putty.

After you have removed the old putty you need to ensure that the window and frame are thoroughly cleaned to avoid moisture from entering. This could include sanding down, stripping paint layers using strippers made of gel, or cutting out rotten sections of timber and splicing them into new ones. If a splice is needed then it must be treated and coated with a protective paint to avoid further damage.

Once all of the old putty is removed it is time to apply some fresh glazing putty on the window. It is recommended to use a high-quality linseed-oil putty, as it will be easier to sand. It also gives 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.

In the case of a broken pane of glass the sash window can be repaired by removing the broken glass, and then filling and re-glazing it with the proper size of new glass. It is easier to accomplish this if the window is removed from its casing; it can be secured on an area of work with the caulked side of the window facing up, or put into a frame for windows that has been opened, and then closed again.

The sash is held in place by putty or (typically in older timber windows) panel pins. When repairing an old historic window it's important to use materials that are similar in appearance, so that repairs don't stick out like a sore thumb. Modern caulks aren't suitable for homes with historical architecture and should be avoided.

It is also important 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; these can block the glass from fitting properly. Also, make sure there isn't any debris in the frame or around the frame which could cause a leak.

You can place a piece of clear tape or concealing tape over the crack in order to hold it in place. This will also prevent the water from flowing through the crack. If glass is at risk of falling off from the sash, solvent-based glue for glass can be used to fill the crack and keep it in the position it is in.

If the casing or sash is in good condition then the issues with draughts, sticky hinges and locks can usually be corrected by cleaning, lubricating and painting.
