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.

Window Repairs Across Cornwall
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.

A repair built around the actual condition
What Window Repairs Across Cornwall can involve
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.
Peeling paint and exposed wood
Loose coatings are removed, the timber condition checked and bare areas prepared before an appropriate exterior primer and finish are applied.
Water ingress
Open joints, failed seals and surrounding water paths are considered before cosmetic work, because repainting alone will not stop recurring moisture.
Sticking windows and hardware
Swelling, hinge or stay wear and alignment are assessed so the cause is addressed without removing unnecessary timber.
Replacement sill sections
Where local repair is suitable, damaged material is removed, replacement timber is fitted and the joint prepared for the agreed exterior coating system.
Sealed glass units
Misted or broken double-glazed units are handled through the dedicated measuring and replacement service.
How the next step works
A clear route from photographs to an agreed scope
Step 1
Photograph the whole opening
Include the sill, lower corners, opening edge and any internal staining or exterior coating failure.
Step 2
Inspect condition and water paths
The frame, hardware, surrounding finish and extent of any softness are checked before the repair method is confirmed.
Step 3
Repair and protect
Suitable local repairs are made, then prepared and finished where decoration is included.

Local FAQs
Questions before booking
Can you repair a rotten window sill without replacing the window?
Often, yes. Localised rot in a sill or frame section can frequently be cut out, spliced and refinished if it is caught early. Send close-up photos and a wider shot so the extent can be assessed first.
Can I send photos before booking a visit?
Yes. Clear wide shots and close-ups help us understand the issue, location, access and likely trade support before arranging the next step.
Do you support holiday lets, landlords and second homes?
Yes. We work with occupied homes, rentals, holiday lets and remotely managed properties, with timing and communication adapted to the property.
How is regulated work handled?
Electrical, gas and other regulated work is handled by suitably qualified support where required. We do not present general maintenance attendance as a substitute for certification.
Can this be included in an ongoing care plan?
Yes. Repeated repairs, seasonal checks and remote-owner reporting may be better handled through a planned care arrangement rather than isolated callouts.

“We recently had Liam from coast and quay Cornwall complete a maintenance project in one of our decorating projects and we were extremely pleased with the results. The quality of the work was excellent, with great attention to detail and a professional finish throughout. Liam was reliable, tidy, and worked around the needs of a holiday property to ensure everything was completed smoothly. It’s great to have a local maintenance company we can trust for our managed properties, and we would happily recommend coast and quay to anyone looking for high-quality property maintenance work. Thanks again, Liam. 👍”
“The plastic sliders on my integrated fridge/freezer doors doors had broken and Liam replaced them so the doors are now as good as new. A small job but done with care.”
“Outstanding workmanship – highly recommended! I honestly cannot recommend Liam highly enough. He was absolutely outstanding from start to finish — professional, polite, courteous, honest, reliable, and also a genuinely funny and lovely person to have around. After being left with what can only be described as a nightmare by a previous builder, who had left room after room and job after job incomplete and poorly finished, Liam came in and took the time to go through the entire house properly. He didn’t just focus on the obvious problems; he picked up on all the little things that had been done incorrectly as well. From adjusting poorly fitted kitchen cabinets so they actually sat correctly, to correcting a toilet waste pipe that had been installed at the wrong height, fixing badly hung doors, carrying out caulking and silicone work, and removing waste pipe connections that had been incorrectly fitted and were leaking before reconnecting them properly — Liam dealt with it all. There were so many jobs around the house that had been done badly or simply left unfinished, and Liam worked through them methodically and professionally, putting things right and leaving them as they should have been in the first place. What really stood out was his attention to detail and the pride he takes in his work. Nothing was treated as “too small” or unimportant, and he was always honest about what needed doing and why. After the experience we had with the previous builder, finding someone like Liam was a breath of fresh air. If it wasn’t for Liam, I genuinely feel I would still be living in the unfinished nightmare that was left behind. Liam is truly one of a kind. I would have absolutely no hesitation in recommending him to anyone, and if I ever need work carried out again, he will be the first person I call. Thank you, Liam, for everything you’ve done — you’ve made a huge difference to our home and we really appreciate it! ⭐⭐⭐⭐⭐”
“Liam did an excellent job fitting our kitchen, was very professional, reliable and a pleasure to work with. Would happily recommend.”
