Aluminium Doors in Hertfordshire
Slim, strong, colour-fast for life. Aluminium is the specification when you want maximum glass, minimum frame and a finish that still looks fresh twenty years after fitting — powder-coated to any RAL and backed by a 20-year finish warranty.
Aluminium Doors designed around family homes across St Albans and Harpenden that want warmth, security and kerb appeal.
St Albans, Harpenden, Watford, Hemel Hempstead and Berkhamsted — we cover Hertfordshire's full palette of Georgian, Edwardian and modern homes with a senior surveyor on the ground every week.
The A1(M) and A41 corridor means Hertfordshire homeowners consistently benefit from acoustic-rated glazing. We spec triple-glazed and laminated options that transform a home's soundscape.

Common questions from Hertfordshire homeowners.
- Are aluminium doors more secure than uPVC?
- The base door is stronger structurally, and both are fitted with the same PAS 24 multi-point locking and 3-star cylinders. In practical terms both meet or exceed the standards insurers require.
- Do aluminium doors need painting?
- Never. A Qualicoat Class 2 powder coat carries a 20-year colour-fast guarantee. Wipe down with warm soapy water twice a year and it stays like the day it was fitted.
- Can I have dual-colour — different inside and out?
- Yes, across the range. Anthracite grey outside with a soft white inside is the most-requested combination in the London market this year.
- Are aluminium doors cold in winter?
- Modern thermally-broken aluminium hits 1.2 W/m²K on a glazed set — indistinguishable from a solid wall of the same era. The cold-alu-frame problem was solved thirty years ago.
