Window Board and Sill Repairs in Swindon – Fix Rot and Water Damage
Your Window Sills Do More Than You Think
Window boards and sills aren’t just decorative. They channel water away from the window frame and protect the wall underneath from moisture damage.
When a window sill is cracked, rotten, or missing, water can get into the wall cavity and cause serious problems. Damp, mould, and rot can spread quickly, and before you know it, you’ve got a major repair job on your hands.
Signs Your Window Board or Sill Needs Attention
Visible rot or decay in timber sills. Cracks or chunks missing from UPVC or stone sills. Water pooling on the sill instead of running off. Damp patches on the wall below the window. Paint peeling or blistering around the window. The sill feels soft or spongy when you press it.
If you’re seeing any of these, don’t ignore it. The problem will only get worse.
What Causes Window Sills to Fail?
Water is the main culprit. If the sill isn’t sloped properly or the drainage isn’t working, water sits on the sill and eventually causes damage.
Timber sills rot when they’re exposed to constant moisture, especially if the protective paint or treatment has worn off. UPVC and stone sills can crack from frost damage or impact.
Can You Repair a Damaged Window Sill or Does It Need Replacing?
It depends on the extent of the damage. Small cracks and minor rot can sometimes be repaired. But if the sill is badly rotten or damaged, replacement is the safer option.
We’ll assess the damage and give you honest advice on whether repair or replacement makes more sense.
How We Fix Window Boards and Sills
For minor damage, we can repair timber sills by cutting out the rotten section and filling it with wood filler or splicing in new timber. We’ll treat the whole sill to prevent future rot.
For badly damaged sills, we’ll remove the old sill and fit a new one. We’ll make sure it’s properly sloped so water runs off, and we’ll seal everything to keep moisture out.
We work with timber, UPVC, stone, and concrete sills, so whatever your window type, we can help.
