uPVC Flush Casement Windows

We install uPVC flush sash windows across Blandford, Poole, Bournemouth, Canford Cliffs, Sandbanks, Westbourne, Wimborne, Shaftesbury, Gillingham, Sherborne, Dorchester, Yeovil, and surrounding areas.

Inspired by the traditional timber joinery of the 19th century, our uPVC flush sash windows have an authentic, stylish look. The iconic design features a sash that sits flush with the frame when closed. This creates a clean, attractive appearance that complements both period properties and modern homes without missing out on the classic charm of the flush sash design.

Our uPVC flush sash windows are the perfect balance between stylish and practical. They offer the appearance of timber frames but do not need the same upkeep. Unlike wood, the high quality uPVC used will not rot, flake or bow. This means that you will not need to paint, sand or varnish your new uPVC flush sash windows. You can spend time on more enjoyable things.
