Don’t let deteriorating timber windows turn into a damp problem.
Replacing windows can be expensive, especially on older properties, but leaving damaged timber frames, cracked paintwork and gaps around the surrounding render can allow rainwater to get into the building, potentially causing just as much expense when it comes to repairing the resulting damp internally.
Once the protective paint coating breaks down and timber starts to deteriorate, rainwater can get into areas it shouldn’t. Keeping timber frames painted and protected, checking joints and seals, and repairing cracks before they become larger problems can help prevent water getting into the building in the first place.
You can’t always justify the cost of replacing windows, so until such time as replacement is practical, maintaining and repairing the existing windows should be the priority.
Don’t ignore the signs. What starts as a straightforward maintenance issue can eventually become a much more expensive repair when damp and damage develop internally.
