Wooden Window Sill Repair & Replacement
Window sill repair is one of our most common call-outs. Often bearing the brunt of the British weather, sash window sills need an experienced hand to repair properly. The external window sill is one of the main sections of timber to deteriorate as, dependent on the elevation, decoration regime, and whether the window is operational, the sill can absorb rainwater which leads to rot setting in. But this can be easily combated if they are maintained properly. Where the sill is too rotten to be economically repaired we craft a new sill from Sapele Hardwood profiling it to match the existing style.

It is often misunderstood that the north-facing windows would be the worst affected because of the lack of sun. In fact the opposite is true; generally, it is the south-facing windows where early deterioration occurs due to sunlight cracking the paint, allowing moisture to penetrate the sill.
The Ventrolla free, no-obligation survey carried out produces a window condition report which identifies whether a sill repair or replacement is required.
Dependant upon the location and amount of rot, sills can be repaired by removing the rotten timber and using Ventrolla’s special wood stabiliser and unique two-part epoxy resin; the Ventrolla VR90 Wood Repair System.
