About Our Doors

First impressions, perfected.

Your front door is the first thing visitors see and the most important security feature on your home. We supply and install premium composite, uPVC and decorative doors — fully bespoke, fully insured, fully guaranteed.

Our doors are supplied by Solidor (44mm solid-timber-core composite) and REHAU (uPVC) — both police-preferred Secured by Design ranges with a 10-year manufacturer guarantee. Every door leaves our workshop with a multi-point locking system, anti-snap 3-star Euro cylinder and reinforced hinge bolts as standard.

You can also design your composite door online in minutes using our official door-builder — pick your style, colour, glass and hardware, and we'll quote the fit within a couple of days.

Aftercare

A modern door needs almost nothing.

  • Wipe the door face with warm soapy water — never white spirit or acetone on the GRP skin
  • Once a year lubricate the hinges and multi-point lock strip with a light PTFE or silicone spray
  • Never oil the cylinder itself — use a dedicated dry lock lubricant like Napier VP90
  • If the door starts to drag or the multi-point stops engaging cleanly, call us — hinge adjustment is a 10-minute job
  • Check the weatherbar and threshold seal every couple of years — we'll replace them under guarantee if worn
