KLIS JOINERY & CARPENTRY LTD
LONDON TIMBER SPECIALISTS
From single home upgrades to multi-unit developments, we supply and install bespoke timber windows built to your exact specification.
Every window is made to measure, double or triple glazed as standard, and finished to a consistent specification, whether you need one window or a hundred.
Call us if you’re experiencing:
No standard sizes forced onto non-standard openings. Each window is measured and built for its specific location, so period proportions, sightlines, and glazing bar patterns are matched precisely, project after project.
Every window supplied includes double or triple glazed units, never basic single-pane glass. That means real thermal and acoustic performance from day one, an important factor for EPC ratings, tenant comfort, and long-term running costs.
Developers and property managers get the same attention to detail on window fifty as on window one. We can price larger orders competitively while keeping specification, finish, and quality identical across the full run.

From a single window to a full multi-unit development, every unit is built to the same specification and finish, so there's no drop-off in quality on larger runs.
No vague estimates. You get a clear written quote before any work begins, including trade and bulk pricing where applicable, so there are no surprises later.
We understand the practicalities of larger projects, phased delivery, site access, and working to a schedule, alongside standard residential jobs.
As a family business, our reputation is attached to every installation. We're accountable for the work long after we've left, whatever the scale of the project.
Reach out to Klis Joinery & Carpentry for an obligation-free discussion and a complimentary at-home consultation to discuss your timber windows. 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.
We visit the property or development, discuss your requirements, and take precise measurements. For larger projects, we talk through phasing, access, and delivery scheduling upfront.
Every window is built to measure, double or triple glazed as standard, with consistent specification and finish across the full order, whether it's a single unit or a large volume run.
Old windows are removed and disposed of responsibly. New timber windows are fitted, sealed, and finished to a high standard, with minimal disruption and a clean, tidy handover.

Get in touch
We offer a full supply and install service. You get one point of contact for the whole project, from measurement through to final fitting, rather than managing separate suppliers and fitters.
Bespoke timber windows typically start from £1,450 per window, supplied and installed, depending on size, style, and glazing specification. Sash and bay windows generally cost more due to the additional materials and fitting time involved. We provide a written quote after discussing your requirements.
Yes. We offer competitive trade and bulk pricing for developers, property managers, and multi-unit projects, while keeping the same specification and finish across every window in the order.
Yes. Every window is built to the same specification, whether the order is for one property or an entire development, so there’s no drop-off in quality or finish across larger runs.
Yes. We expertly install single glazing, double glazing, or triple glazing, depending on our clients’ needs. When they’re unsure, we offer honest advice on which solution is best for their home.
Double glazing offers a strong improvement in warmth and noise reduction for most London homes. Triple glazing goes a step further and suits properties on busier roads or where maximum heat retention is a priority. We can talk through which makes sense for your windows.
Yes. We regularly coordinate supply and installation across multiple boroughs for property managers and developers with more than one site, rather than treating each address as a separate project.
Timelines depend on order size and specification, but bespoke manufacture typically takes several weeks, followed by installation scheduled to suit your access and phasing requirements. We’ll confirm exact timings at quote stage.
