Klis Joinery & Carpentry Ltd is built around a simple idea: wooden windows should look good, work smoothly, and last for many years. From our base in London we focus on timber sash and bay windows, offering supply, installation, repair, and full refurbishment for homes across the city and surrounding areas.
As a family run company, our name is attached to every job we complete. We have been replacing and repairing wooden sash windows for more than a decade, working on period town houses, flats, and modern homes that want the warmth and charm of real timber frames. Our team brings the same care to a single repair as to a full house replacement.
Much of our work starts with windows that no longer open, draughts that make rooms hard to heat, or frames which have suffered from years of damp and paint. We carefully assess each frame and sash, explaining whether repair, part replacement, or full new windows will give the best long term result. Where possible we retain original timber and hardware to keep the character of the building.
When new windows are needed, we supply and install timber sash and bay units built to suit your property. These can include double or triple glazing, modern draught proofing systems, and secure fittings, all installed with careful attention to detail. The aim is to give you the comfort and performance of a new window while keeping a classic appearance that suits London homes.
We also provide ongoing care for existing windows, from sash cord replacement and balance repairs to frame restoration and sealing gaps. For urgent issues, such as broken panes, sashes that will not close, or damage after a storm, we offer a responsive service for emergency windows and conservatories, helping to keep homes safe and weather tight.
Across every project we remain focused on clear communication and tidy work. We keep you updated on progress, protect floors and furnishings, and leave your home clean at the end of each day. Many of our new customers come through personal recommendations and independent review platforms, which reflects the care we put into every window we touch.
A close team with more than ten years of hands on experience in wooden sash and bay windows, treating every home as if it were our own.
Classic timber frames combined with modern draught proofing, double and triple glazing, and careful sealing to keep homes warm, quiet, and efficient.
We visit, inspect your windows, and talk through repair and replacement options in simple terms, with written quotations and no hidden extras.
