How to Repair Timber Windows
To ensure that timber windows remain functional and free of swelling and decay they require regular maintenance. Sash windows that have not been properly maintained or treated can be prone to rattling or sticking.

Examine the Condition
Wooden windows are an attractive addition to any home. They offer natural beauty as well as a high degree of security. However, they can be susceptible to deterioration and damage and the condition of wooden window frames and sashes should be checked regularly to ensure that they are still functioning as intended.
One of the biggest issues facing timber window frames is decay. Wood is susceptible to rot due to excessive water exposure which can cause wood to become spongy and soft. The good news is, the rot can be dealt with patience and effort.
To determine the condition of timber windows You should first look for signs of damage like cracks, loose parts and even a few pieces. Examine the weather stripping of the windows to ensure that they are properly sealed to prevent water infiltration.
It's important to test for softness if you notice any signs of rotting. You can do this by pressing them down with an instrument like a screwdriver, or your finger. Solid, healthy 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 rather than try to fix it.
Once the damaged sections of the timber have been treated, it's now time to remove them from the wood. It's best to start with a sandpaper of coarse-grit, then move on to finer grits until your repaired area is smooth and blends seamlessly into the remainder of the window. After sanding the damaged area, it can be primed, then painted to make the repair appear invisible.
In certain cases where the rotting is serious and the timber is not strong enough to be repaired, it may be necessary to have an lintel placed above the window. It is structural support beam that carries the weight of walls over the cavity in which the frames of timber are. A structural engineer can install an lintel in order to prevent deterioration and decay of older timber windows.
Take the Glass off
It is easier to deal with broken glass when you take the window from the frame. This makes the job much simpler. You'll want to guard yourself from the razor-sharp shards by wearing gloves and using a towel while wiggling out every piece of glass.

If the hinges and sashes become difficult to open or close it's usually an indication that they're worn-out or out of alignment and need to be re-adjusted.
A lot of timber window issues are the result of weather and moisture. Moisture uptake creates local stress in the exposed joints that are glued, which can result in them opening and allowing moisture to penetrate the frame. This can lead to the staining of moisture.
Fortunately, modern timbers such as Accoya and Red Grandis are able to withstand more damage than traditional timbers and therefore it's worth checking with your preferred joinery company to find out what timbers they have available. It's crucial to choose the right type of timber since different woods expand and contract at different rates, and choosing the wrong one could result in damage and a shorter life span for your new timber windows.
Remove the old Putty
Wooden windows are a typical feature in older buildings. They can be restored to make them look beautiful and serve their purpose that include letting light in, blocking out rain and providing insulation. Timber frames can become rotten if they are neglected. When this happens, the integrity of the windows can be damaged and replacement is necessary.
The first thing that needs to be completed is to check the condition of the frame and glazing putty (the material that holds glass panes into the wooden sash). If large sections of timber are badly damaged, it may not be possible to save them but they can be connected and then treated so that the remaining part of the window remains functional.
If you decide to go by making repairs, the next step is to unhook the sash from the carrier and place it on a solid level surface such as a workmate. You might also want to remove the handle and seals at this time so you can examine them.
There are a variety of different products that can be used to loosen and remove old putty. repairing double glazed windows of the most effective is to make use of a little of Household Chlorine Bleach mixed with Raw Linseed Oil. The mixture is applied liberally to the old putty and then left to sit for 15 to 20 minutes prior to scraping it off with a razor or chisel. This process should be repeated several times to get rid of all the old putty.
After removing the old putty, it is important to make sure that the frame and window are thoroughly cleaned to stop moisture penetration. This could mean stripping paint with gel type removers or cutting out rotten timber sections and splicing new ones. If a splice has to be made, it must first be protected with a paint, and then painted.
After removing the old glass putty, it's now time to apply a new one to the window. A good-quality linseed oil putty is recommended as it will be easier to sand and will provide an attractive finish to the window. It is a good tip to roll out a small amount of putty and then form an oval shape before applying it to the frame of the window.

It is simpler to accomplish this if the window can be removed from its casing; it can be firmly clamped on a work surface with the caulked side facing upwards, or placed in a window frame that's been opened and then closed again.
The sash will be held in place by putty or (typically in older timber windows) panel pins. It's important to choose materials that look similar when repairing an older 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.
The new glass will not fit properly if there are spots of paint or putty in the rabbet grooves. Check for debris around the sash or in the window frame. This could lead to leaks.
A piece of clear tape or concealing tape can be placed over the crack to hold it in place and to stop water seepage through gaps that may create. If the glass is in danger of falling off from the sash, solvent-based glass glue can be used to fill the crack and hold it in place.
If the casing or sash is in good shape, the problems with draughts, locks and hinges that are sticky can usually be corrected by cleaning or lubricating the area and painting. If you're not confident about tackling these simple maintenance tasks yourself then a joiner or a company that is specialized in overhauling windows made of timber might be able to assist.
