Expert Draught-Proofing Windows and Doors Sevenoaks

Specialist Draught-Proofing for Traditional Wooden Sash Windows in Sevenoaks

Many properties in Sevenoaks and the surrounding villages still feature original timber sash windows, especially homes in heritage areas or buildings with conservation restrictions. While PVC windows have become a common modern replacement, these protected homes must keep their traditional sash windows in place — and as charming as they are, older timber frames often struggle to keep out cold air and coastal winds.

That’s where we come in.

At Crimson Property Maintenance, we specialise in draught-proofing wooden sash windows to improve comfort, reduce heat loss, and ensure smooth operation — all without replacing your existing frames. Using discreet, conservation-friendly methods, we seal gaps, stop rattling, and upgrade insulation while preserving the authentic character of your property.


With over 30 years of experience working on period homes across Sevenoaks, we provide expert solutions that make your sash windows warmer, quieter, and far more energy-efficient, helping you enjoy the benefits of modern performance without losing the charm of traditional craftsmanship.

Sash Window Draught-Proofing
