How to Repair Timber Windows
Timber windows can be an attractive feature of a house. However, over time and exposure to extreme weather conditions, they could begin to degrade.
Repairs are cheaper than replacing window frames. This will help you save money and the home will retain its original character.
Repairing rotten wood
Wooden window frames are exposed to the elements all year round, and are often one of the first parts of a house to be affected by damp and damage. Fortunately, wood that is rotten can be repaired and addressed quickly. It is important to identify the issue and take action as soon as you can. Otherwise, it can worsen.
In the beginning, it is essential to determine the extent of the rot and decide whether it's salvable. A thorough external survey is usually a good place to begin, looking for slates or tiles that are damaged on the roof or gutters that are blocked, as well as deficient damp proof course (DPC). It's also recommended to inspect the inside of the home including basements and cellars and joist ends that are non-cavity walls.
As soon as you have identified the area that is affected by the rot, it is essential to eliminate the decayed wood as much as possible. This will lessen the amount of damage and allow you to finish the repairs. The next step is to make use of a pry bar, or a clawed hammer to remove as much of the decayed timber as you can. This can be a bit difficult however, if you insert the clawed end of the pry bar into the corner and pushing it against the healthy board you should be able to create enough force to break the old timber.
When you remove the rotten wood Make sure you leave a gap between the two. This will help prevent moisture from entering the gap and causing further damage to the surrounding timbers. It's also worth removing any nails and other debris from the area to minimise the risk of further leaks and damage.
Wood filler or epoxy can be used to fix the remaining boards after removing the rotten wood. This is a relatively affordable and simple method to repair wood rot on windows made of timber. It can be sanded and painted to match your current frame.
If the severity of the decay is serious, however, it may be more economical to replace the entire window frame with a new one, especially if you're seeking an ongoing solution that will ensure that moisture isn't able to penetrate further.

There are two main categories of timber: hardwoods and softwoods. Hardwoods are broad-leafed deciduous trees. They have an extremely complex cellular structure, which gives them good dimension stability. Softwoods are composed of needle-leaf or coniferous trees, and their cellular structure is much simpler.
Traditionally, the structural joints of timber frames were created by mortice and tenons, or the comb joint. These joints are nailed or pinched into place, but are not bonded using adhesive. Over time, water ingress freely flows between sections of timber, resulting in rot or staining. Poor craftsmanship can be a contributing factor. Fixtures that aren't properly installed or not properly covered can allow moisture be introduced into the frame. If this is allowed to occur it can lead to the staining of rust and water deposits on window frames.

If properly maintained and painted these windows can provide the longest service. They can also be fitted with burglar-proof glass that increases the force required to open the window and makes it harder to smash.

This can be accomplished by either cutting out the damaged section to at least 5 centimeters past the point of rot or by removing the entire sash and splicing it into a new piece.
The final step is treating the wood with a preservative. This will stop moisture from getting into the wood, which could cause it to rot and weaken the structure of the frame. It is essential to paint your windows regularly in the event that you don't intend to treat them.

Before you begin painting, it's a good idea to clean the entire frame with a soft, damp cloth and then remove any oil or grease marks. This will stop you from spreading dirt and make cleaning much easier. It's also worth taking off the handles on your windows If you have them and putting them to one side. This will make it easier to work on the frames without having to worry about breaking the glass.
