About – Kellys Sash Windows

For over 25 years, Kelly’s Sash Windows has been trusted across London, Reading, Berkshire and the South East for our expert craftsmanship, reliable service, and passion for preserving the charm of traditional timber sash windows.

We are a family‑run business combining time‑honoured joinery skills with modern technology to deliver windows and doors that are beautiful, durable, and energy‑efficient. From restoring listed and period properties to fitting bespoke double‑glazed timber sash windows in modern homes, every project is completed to the highest standard.

Craftsmanship That Lasts

We know that no two homes are alike. Every window and door we make is custom‑built, ensuring a perfect fit and faithful match to your property’s original style. Our experienced craftsmen work with premium timbers such as Red Grandis, chosen for strength, sustainability, and long‑lasting beauty.

 Meets Modern Comfort

Traditional sash windows are a defining feature of period homes, but older single‑glazed units often mean draughts, heat loss, and noise. Our double‑glazed sash windows retain all the charm of the original design while improving insulation, reducing noise, and enhancing security.

Local Experts You Can Trust

Operating from our workshop in Berkshire, our team understands the unique character of local architecture and the importance of preserving it. We work with care and respect, minimising disruption and keeping our workspaces tidy at all times.
