The UK's No.1 Composite Door — Voted Best Brand 5 Years Running
Hallmark Doors & Panels manufacture the UK's most specified composite door range. At the core of every door is a high-density polyurethane foam slab wrapped in a high-impact GRP (Glass Reinforced Polyester) skin — moulded to replicate the authentic grain and texture of timber with a precision that cheaper alternatives simply cannot match.
Hallmark doors have been independently tested to be 19% more thermally efficient than timber — and significantly outperform uPVC. The 2025 range introduces the HallMAX PRO double-rebate frame, a 70mm twin-seal system that represents the pinnacle of composite door engineering available anywhere in the UK.
We are authorised Hallmark installers serving Caterham, Whyteleafe, Purley, Coulsdon, Oxted, and surrounding Surrey areas. Every door is surveyed, supplied, and fitted by our own installation team — no subcontractors.

What Our Customers Say
“Had the Tuscan 3 fitted in Anthracite Grey with the Danthorpe Cross glass. It has completely transformed our front entrance — so many compliments from the neighbours. The installation team were professional, tidy, and finished well ahead of schedule.”
Jennifer Marsh
Caterham, Surrey
“We chose the Lancia 4 in Chartwell Green for our rear kitchen door — couldn't be happier. The door looks exactly like a real timber board door but we've had zero maintenance issues in 18 months. Ensure Windows were honest about pricing with no hidden extras whatsoever.”
Mark & Lisa Dawson
Whyteleafe, Surrey
“Went for the Seville in Deep Lagoon — one of the new Deluxe Matte colours. It is an absolute statement door and I get comments every week. Very impressed with the Hallmark quality and the knowledge of the Ensure Windows team throughout.”
