Window Sill Repair FAQs

Can you repair wooden sills without replacing? +
Yes, in most cases. We use resin and timber splicing techniques to repair damaged sections without replacing the entire sill. This is faster, cheaper, and maintains the original character of your windows.
Why do window sills rot? +
Window sills rot because water sits on them. When paint breaks down, moisture gets into the bare wood. The ends where sills meet the frame are particularly vulnerable as water collects there. Regular painting is the best prevention.
Can you replace just the ends? +
Yes, we often splice in new timber ends where the rot is concentrated. The joint is cut at an angle (a 'scarf joint') for strength, glued, and shaped to match. Once painted, the repair is invisible.
Do you repair stone sills? +
Yes, we repair stone and concrete sills as well as wooden ones. We can fill cracks, rebuild damaged sections, and apply protective coatings to prevent future damage.
How do I prevent sill rot? +
Regular painting is key - repaint before the existing paint breaks down. Keep sills clear of plant pots and debris. Check the angle to ensure water runs off. Inspect annually for early signs of damage.
