Our services
A small failure may need a repair. A compromised frame may deserve full renewal. A larger project may need new doors, specialist glass or one exterior programme.
Bespoke replacement to the highest standard
Bespoke hardwood box frames and sashes made for the opening when renewal is the better long-term investment.
Front, French and stained-glass doors
Made-to-measure hardwood front, French and glazed doors, crafted to complement the character and proportions of the property. Where original doors remain sound, careful repair and restoration may be the better approach.
Preserve sound, original joinery
Careful, targeted work to extend the life of original sash windows while retaining as much historic timber as possible.
Windows, doors, masonry and finishes considered as a whole
A coordinated approach to restoring the exterior of the property, bringing together timber joinery, masonry repairs, preparation and decoration within one programme of works.
Improve performance, retain the original box frame
Made-to-measure hardwood sashes with slim double glazing, fitted into a suitable existing box frame and carefully detailed to preserve traditional proportions.
Restore tired joinery properly
A more comprehensive approach to original windows, combining joinery repairs, thorough preparation, servicing and redecoration to restore both appearance and performance.
Repair and replacement, carefully considered
Localised decay, failed sash cords and deteriorated putty can often be repaired without replacing otherwise sound joinery. More extensive frame decay, distortion or unsuitable previous replacements may call for complete renewal.
Our survey assesses each opening individually, establishing what should be retained and where replacement is the better approach.
Address localised defects while retaining sound original joinery.
Bring original windows back into good condition through timber repair, preparation, servicing and redecoration.
Improve performance with new double-glazed hardwood sashes fitted into a sound existing box frame.

Customer reviews
The Google Business Profile showed a 5.0 rating from 60 reviews when checked on 21 October 2026.
“Great quality work, the windows they restored are beautiful.”
“I highly recommend Joe and Sam. Their expert exterior paint work has transformed the front of my house masonry, railings and gate. Every time I walk down the front path, I notice it. They also expertly fixed some exterior flashing on the top floor at the rear of the property which was loose. Their work was neat and tidy and they were a pleasure to have around. I highly recommend this company.”
“Thanks to Joe and the team. They did an excellent job of draft proofing my front door. Would definitely recommend them!”
First-hand guides
Our guides explain what to consider when repairing, restoring or replacing traditional joinery, with practical advice on windows, doors, glazing, shutters and wider façade works.
7 minute guide
The right approach depends on the condition of the existing joinery. A sash window may need a localised repair, new double-glazed sashes within the original box frame, or complete replacement. The starting point is always the condition of the window itself.

The repair, glazing, access and finish decisions that change a sash-window quotation—and the information that makes quotes comparable.

How air leakage, glass temperature and external noise differ—and why a serviced sash can outperform expectations without immediate replacement.
Read the guide8 minute guide
If the original box frame remains sound, complete window replacement may not be necessary. New made-to-measure hardwood sashes with slim double glazing can often be fitted into the existing frame, improving performance while retaining more of the original joinery.

What sill decay usually reveals, how local timber repairs are formed and when the damage has moved beyond an isolated splice.
Read the guide5 minute guide
A sash window that will not open properly is not necessarily badly damaged. Paint build-up, swollen timber, failed sash cords, balance problems or movement within the frame can all cause a window to stick—and each requires a slightly different approach.
Read the guideHow it works
No work is ordered until the window has been assessed and the scope has been agreed.

We check the frame, sashes, working parts, access and visible details.
You receive a clear recommendation and quotation before work is booked.
The work is fitted, adjusted and checked, and the working area is left tidy.
Local team, local knowledge
Each guide covers the property styles, access questions and common sash window or timber door problems found across the 19 areas Stile now targets.
If the box frame and most of the sash timber are sound, repair or restoration is often the better starting point. Renewal makes more sense when decay is extensive, movement is serious or the existing design is unsuitable.
Yes. Discreet brush seals can be machined into new beadings and meeting rails, then the sashes are balanced and serviced.
Sometimes. A sound box frame can often receive new made-to-measure double-glazed hardwood sashes. The survey checks condition, profiles, glass specification and planning context.
Yes. Stile repairs, refurbishes and replaces timber front, French and glazed doors, including draught, alignment and local rot issues.
