Rotten Window Repair FAQs

How much rot can you repair? +
Often up to 80% decay can be addressed. We cut out the rotten sections and splice in new timber, using scarf joints for strength. Combined with resin repairs for smaller areas, we can restore windows that look beyond saving. Only if the frame has completely disintegrated would we advise replacement.
Is it worth repairing badly rotten windows? +
Usually yes, unless the frame has completely failed. Even extensive rot can be repaired by splicing in new timber sections. The cost is typically 60-80% less than replacement, and you keep the original character of your windows.
How do you stop rot returning? +
Proper treatment, primer, and paint are essential. We treat all exposed timber with preservative, apply appropriate primers, and leave surfaces ready for a good quality exterior paint. Regular repainting (every 5-8 years) prevents moisture getting back in.
What causes window rot? +
Moisture getting into bare wood is the main cause. This typically happens when paint breaks down, allowing water to penetrate. South and west-facing windows suffer most due to weather exposure. Regular painting is the best prevention.
How much can I save vs replacement? +
Typically 60-80% cost saving compared to new windows. A replacement wooden window can cost £800-1500+ installed. Our repairs usually range from £175-750 depending on damage extent, saving you hundreds or thousands per window.
