KLIS SASH WINDOWS
LONDON TIMBER SPECIALISTS
FULHAM | LONDON
Bespoke timber sash windows for Fulham’s Victorian and Edwardian terraces. Period-accurate, double glazed, and fitted to complement the architectural character your street is built on.
Fulham’s housing stock is among the most uniform and architecturally coherent in south-west London. The Victorian terraces of Parsons Green and Walham Green, the Edwardian streets of the Peterborough Estate, and the substantial properties around Hurlingham Park share a consistent character — and sash windows are central to it. On streets where every home looks the same, the quality of any window work is immediately visible.
You won’t be passed to a call centre or handed to a subcontractor. Klis, Besi and the team attend every Fulham job personally, from first survey through to final handover.
01
Fulham’s terraced streets have a visual consistency that makes any deviation in window profiles or glazing bar proportions immediately apparent. We take every measurement from your existing frames — horn details, meeting rail heights, sash weight configurations — and reproduce them so precisely that new windows sit as though they were always part of the building.

Fulham falls within the London Borough of Hammersmith & Fulham, which administers 44 designated conservation areas — Hurlingham, Parsons Green and Fulham Reach among the most significant for period residential properties. LBHF produces individual character profiles for each area, and permitted development rights can be restricted even for like-for-like window replacements. We know the council’s requirements and can tell you exactly what applies to your property before you make any decisions.

Surface rot can be repaired, but when deterioration reaches the structural timber, the equation changes. Wood that feels soft or hollow around the sill or frame corners has lost its integrity — patching it buys time rather than solving the problem.
In Fulham's Victorian and Edwardian terraces, single-glazed sash windows are often the primary source of heat loss. Cold spots at the frame, condensation forming on the glass, or road noise passing through easily are reliable indicators that double glazing will deliver a tangible, lasting improvement.
Sashes that stick, cords that have snapped, and frames that no longer sit square are common complaints in older Fulham homes. Where wear has progressed to the point where the window can't open reliably or close without a gap, replacement becomes the more sensible long-term investment.
We visit your Fulham property, inspect your windows on-site and follow up with a detailed written quote. No middlemen, no pressure, no obligation to proceed.

There’s no hard sell here. Our job is to give you straightforward, trustworthy advice — the decision is always yours.
Where the main timber frame remains solid, repair is almost always the right starting point. Cord failures, draught issues, loose sashes and localised surface rot can all be addressed without touching the whole window. Once deterioration reaches the core structure — or where rotting is extensive — replacement becomes the more practical route, particularly if you’re also considering an upgrade to double glazing. We give you an honest view during a free home visit and won’t push replacement when a repair is the sensible answer.
Absolutely — accurate period matching is a core part of what we offer. Fulham’s terraced streets have a visual uniformity that means any deviation in profile or proportion becomes obvious, so we take detailed measurements from your existing windows and reproduce every element — glazing bar configuration, meeting rail position, horn profile and overall proportions — with precision. The result looks like it’s always been there.
Yes. Every replacement we produce can be fitted with sealed double-glazed units within a traditional timber frame, giving you noticeably better insulation and sound reduction without changing the period look of the window. Triple glazing is also available — worth considering for Fulham properties on busy through-roads where traffic noise is a factor.
Yes. The London Borough of Hammersmith & Fulham oversees 44 conservation areas and has produced detailed character profiles for each one — these inform planning decisions and set out what materials, profiles and designs the council considers appropriate. In many parts of Fulham, permitted development rights don’t extend to window replacement, meaning a planning application is required even for a like-for-like change. We’re experienced with LBHF’s approach and can advise on what your specific property and listing status will require.
Most residential jobs covering two to four windows are completed in a day or two once the windows have been manufactured. For larger projects spanning a full property, we plan the sequence carefully to keep exposure time to a minimum. You’ll receive a clear programme at the survey stage, and we work efficiently to limit disruption to your household throughout.
Our windows are made from sustainably sourced African Sapele hardwood — chosen for its dimensional stability and natural resistance to the moisture and seasonal movement that affects timber in the UK climate. Every piece is pre-treated before installation. With a fresh coat of paint every five to seven years, a well-made timber sash window will serve a Fulham home for decades. We’ll walk you through the maintenance routine at handover.
Always. Removal and disposal of existing frames is included as standard — there’s nothing extra to pay for this. We protect walls, floors and surrounding finishes throughout the installation, clear the work area completely before we leave, and test each window in full to confirm it opens, closes and seals as it should.
Pricing depends on the number of windows, individual sizes, glazing specification and any complexity involved in period matching or working within conservation area requirements. As a guide, fully installed replacement sash windows start from around £1,200 per window, varying with size and configuration. The most reliable way to get an accurate figure is a free home visit — we’ll assess your windows, talk through your priorities and produce a detailed written quote, with no pressure to go ahead.
