Timber is one of the major components of almost any house. However, its quality can fast deteriorate, if not maintained properly. Dampness poses the major threat to this material and makes it susceptible to rot and decay. This results costly damages to structures such as wooden windows. Some damages are severe while others can be simply repaired. Therefore, it is important to learn how to repair rot and decay on wooden windows.
It is good to know some basics of the problem first. The condition is actually caused by a saprophytic fungus that grows on the material. The moisture only creates a supportive environment for its growth. As the fungus grows, it makes the timber an ideal food source causing the damage.
Before getting to the actual repair, it is crucial to thoroughly inspect the damaged structure in order to identity all areas that were affected. Joints, lower rails, and upright pieces especially require attention. Also pay special care to areas which are in close to damp walls. Glazing beads tend to also be affected, especially if the external putty failed, or if the beads are fixed without it in the first place.
You should also know how to confirm a particular area is affected. The affected timber becomes extremely soft. Most signs become visible after the dampness is gone and the surface starts to collapse and shrink. To confirm, you can simply prod the area with a screwdriver. It will slip in easily if the timber is affected. If the damage is not severe, there will be no need to panic since the problem can be treated.
Start by treating the area with liquid wood hardener as well as good quality putty. The first step is to drill holes in the damaged area, using a honeycomb pattern, and filling them with hardener. Doing so ensures that the liquid can reach the entire affected area. After filling the holes, give the liquid time to harden.
After the hardener is completely dried, you can cover the holes and cracks with some high quality putty. To recover the smoothness the putty has to be sanded down later. This will complete the work and make the entire surface look uniform.
By now you must know how to repair rot and decay on wooden windows and therefore you can deal with minor problems. However, you must still ensure proper maintenance of the timber. This will eliminate expensive replacements.
