Rotten window sills
Localised decay can sometimes be cut back to sound timber and repaired without replacing the complete window, provided the remaining frame is suitable.

Local property care
Repairs for sticking, draughty or weather-worn windows, timber sills and frames in Cornwall homes, cottages and holiday lets.
Salt-laden wind and driving rain attack window sills, frames and seals faster on the coast, and older cottage windows often swell or stick after damp winters.
Quick price request
Add the Cornwall town, job type and photos where useful so the request can be assessed with the right context from the start.
A repair built around the actual condition
This established window-repair page is the canonical home for rotten wooden window-sill repair as well as sticking openings, hardware and timber-frame concerns. Keeping the intents together avoids a competing thin window-sill URL.
Localised decay can sometimes be cut back to sound timber and repaired without replacing the complete window, provided the remaining frame is suitable.
Loose coatings are removed, the timber condition checked and bare areas prepared before an appropriate exterior primer and finish are applied.
Open joints, failed seals and surrounding water paths are considered before cosmetic work, because repainting alone will not stop recurring moisture.
Swelling, hinge or stay wear and alignment are assessed so the cause is addressed without removing unnecessary timber.
Where local repair is suitable, damaged material is removed, replacement timber is fitted and the joint prepared for the agreed exterior coating system.
Misted or broken double-glazed units are handled through the dedicated measuring and replacement service.
How the next step works
Step 1
Include the sill, lower corners, opening edge and any internal staining or exterior coating failure.
Step 2
The frame, hardware, surrounding finish and extent of any softness are checked before the repair method is confirmed.
Step 3
Suitable local repairs are made, then prepared and finished where decoration is included.
