Why Hertfordshire Homeowners Choose Timber Sash Windows
Hertfordshire is home to thousands of Victorian, Edwardian and Georgian properties — and traditional timber sash windows are a defining feature of their character. Beyond aesthetics, original sash windows add value to period properties and are often required by conservation area guidelines. Replacing them with uPVC is rarely an option, and even when it is, it diminishes the property's appeal and authenticity.PM Windows specialises exclusively in timber sash windows — repair, restoration and replacement — for period homes across Hertfordshire.

- Broken sash cords and failed pulley mechanisms
- Rotten or decayed timber sections
- Rattling and draughty frames

- Failed putty and glazing
