KLIS JOINERY & CARPENTRY LTD
LONDON TIMBER SPECIALISTS
HAMMERSMITH | LONDON
Bespoke timber sash windows for Hammersmith’s period properties. Precisely fitted, double glazed, and made to respect the architectural detail your street was built with.
Hammersmith has a rich mix of period housing — from the Regency villas of St Peter’s Square to the Victorian terraces of Brackenbury Village and the Edwardian streets around Brook Green. Sash windows are a defining feature across all of it, and on streets with this much character, workmanship is visible.
Klis, Besi and the team handle every Hammersmith job directly. No call centres, no subcontractors.
01
Period streets in Hammersmith leave little room for error — wrong proportions or mismatched glazing bars are hard to miss. We work from your existing frames, matching every profile, meeting rail and sash weight so that new windows are a precise fit for the building.
02
Hammersmith sits within LBHF’s 44 conservation areas, with St Peter’s Square, Ravenscourt and Brackenbury among the most significant for period homes. Permitted development rights are often restricted, and LBHF applies its own character guidelines to window work. We know what the council requires and can advise before you commit.
03
Every job — survey, installation, finishing — is done by our own people. You get the same crew and the same standard throughout, with no work passed elsewhere.

Once rot moves into the structural timber, the window's integrity is gone. Soft or crumbling wood at the corners or sill can't be filler-fixed permanently — at that point, replacement is the only reliable answer.
Single-glazed sash windows are often the biggest source of heat loss in Hammersmith period homes. Persistent cold at the frame, condensation on the glass or noise from the street coming through clearly are all signs that double glazing will make a real difference.
Stuck sashes, failed cords and out-of-square frames are typical in older Hammersmith properties. When the window can no longer function or seal reliably, replacement is the more practical solution.

No sales pressure, no jargon. Just clear advice so you can make the right call for your property.
If the core frame is sound, repair is usually the better route — cord replacements, draught fixes, rattles and small rot patches don’t require a full new window. Where structural timber has failed or you want double glazing, replacement makes more sense. We’ll tell you honestly which applies after a free home visit, and we won’t push replacement when it isn’t needed.
Yes. We take all measurements and reference points from your existing windows and reproduce profiles, glazing bars, meeting rails and overall proportions to match exactly. Hammersmith properties range from Regency to Edwardian — whatever the configuration, the new windows will match what was there.
Yes. Our replacement sash windows come with sealed double-glazed units in traditional timber frames as standard — better insulation and sound performance without altering the period look. Triple glazing is an option too, particularly suited to Hammersmith properties on high-traffic routes.
Yes. Much of Hammersmith sits within LBHF conservation areas, and window replacement can require planning permission even on a like-for-like basis. The council’s character profiles set out specific expectations for materials and profiles in each area. We’re familiar with LBHF’s approach and can advise on your property’s requirements before any decisions are made.
A standard job of two to four windows typically takes one to two days on-site once the windows are ready. For whole-property projects we schedule carefully to reduce exposure time at each opening. You’ll get a clear timeline at the survey stage, and we work to keep disruption brief.
We build with sustainably sourced African Sapele hardwood — stable, durable and well-suited to the UK climate. All timber is pre-treated against moisture and movement before installation. Repainted every five to seven years, a good timber sash window will last for decades. We’ll advise on upkeep at handover.
Yes. Old frame removal and disposal is included in the price — no extras. We protect walls, floors and finishes while we work, tidy up fully before leaving, and run through each window to check it opens, closes and seals properly.
Price depends on window count, size, glazing choice and any period matching or conservation area considerations involved. As a rough guide, fully installed replacement sash windows start from around £1,200 per window. A free home visit is the best way to get a firm figure — we’ll look at your windows, discuss your needs and provide a written quote with no obligation.
