KLIS JOINERY & CARPENTRY LTD
LONDON TIMBER SPECIALISTS
RICHMOND | LONDON
Bespoke timber sash windows for Richmond’s Victorian and Edwardian homes. Double glazed, draught-free, and built to match your property’s original character.
Richmond has one of the most distinctive housing stocks in London. The Victorian and Edwardian terraces of St Margarets, Kew and East Sheen, and the Georgian properties climbing Richmond Hill, are defined by their sash windows, and that means the standard of workmanship matters.
We’re not a franchise, and you won’t speak to a call centre. Expect Klis, Besi and the team to visit every Richmond job personally. No subcontractors, no handoffs.
01
On a street where every property has the same window type, poorly matched profiles or wrong glazing bar proportions will stand out immediately. We replicate the originals exactly — horn profiles, meeting rail dimensions, sash weights — so replacements are indistinguishable from what was there before.
02
A significant part of Richmond falls within designated conservation areas — Richmond Hill, Kew Green, St Margarets and Petersham among them. We know what’s permitted, understand the council’s requirements, and can advise you before you commit to anything.
03
Every survey, fitting and finishing detail is handled by our own team. Not passed to whoever is available that week — the same people, the same standard, every time.

When timber deterioration goes beyond the surface, repairs become short-lived and poor value. Soft, spongy or crumbling wood around the frame corners or sill means the structure is compromised — and no amount of filler will hold it long-term.
Single-glazed sash windows in Richmond's Victorian terraces can account for a significant portion of heat loss. If your rooms feel cold near the windows, condensation builds on the glass, or outside noise carries through clearly, replacement with double-glazed units will make a measurable difference.
Jammed sashes, broken cords, and frames that have dropped out of square are common in older properties. When the mechanism is too worn to function reliably—or the frame has shifted enough that the window can't seal—replacement is the more practical long-term fix.
We come to you, assess your windows in person and provide a clear written quote. No call centres, no pressure, no obligation.

We’re not pushy, and we’re not a hard-sell. We’re here to offer sound, reputable advice that allows you to make an informed decision!
Repair is usually the right call when the core timber frame is still structurally sound — broken sash cords, minor draughts, rattling and small areas of surface rot can all be fixed without replacing the whole window. Replacement makes more sense when frames have deteriorated beyond repair, when timber has rotted through, or when you want to upgrade to double glazing. We’ll assess your windows honestly during a free home visit and tell you which option is right — we won’t recommend replacement if a repair will do the job.
Yes — this is central to what we do. We replicate original profiles, glazing bar layouts, meeting rail positions and proportions exactly so that replacement windows are indistinguishable from the originals. Whether you have Victorian two-over-two sashes, Edwardian six-over-six, or something more unusual, we work from your existing windows to ensure the replacements are a precise match.
Yes. All our replacement sash windows are available with modern sealed double-glazed units fitted into traditional timber frames. This gives you significantly better thermal performance and noise reduction while keeping the period appearance intact. Triple glazing is also available for properties on particularly busy roads or where maximum insulation is a priority.
Yes, we have extensive experience working within conservation area guidelines and on listed properties across London. Permitted development rules vary by borough and listing status — we can advise you on what’s likely to be approved before you commit to anything, and we’re familiar with the typical requirements around timber frames, slim-profile double glazing, and matching original designs.
For a typical residential job — two to four windows — we’d normally complete the work in one to two days after the windows have been crafted. Larger projects covering a full property are planned carefully to minimise the time any opening is exposed. We’ll give you a clear timeline when we visit, and we keep disruption to a minimum throughout.
We use high-quality, sustainably sourced African Sapele hardwood selected for stability and longevity. All timber is treated before installation to resist moisture, rot and warping. Properly maintained — painted every five to seven years — good quality timber sash windows will last decades. We can advise on the best finish and maintenance routine when the job is done.
Yes, always. Removal and full disposal of old frames is included as standard — there are no hidden charges for this. We protect surrounding walls, floors and finishes during installation, and we leave every work area clean and tidy before we go. We also test every window before we leave to make sure it opens, closes and seals correctly.
Costs vary depending on window size, number of windows, glazing specification and any complexity around period matching or conservation requirements. As a general guide, most replacement sash windows start from around £1,200 per window fully installed, depending on the size and configuration. The best way to get an accurate figure is a free home visit — we’ll assess your windows, discuss your requirements and provide a detailed written quote with no obligation to proceed.
