Trade door FAQs
Quick answers for installers and builders sourcing the best uPVC doors, composite doors and aluminium bifolds from our Leeds manufacturing centre.
We manufacture our uPVC door (unplasticised polyvinyl chloride ) panels using Eurocell profiles, with steel reinforcements throughout. Composite doors come from DoorCo and aluminium bifolds from Alunet, giving installers proven raw materials for long-term longevity.
Every door leaves our factory with Secure by Design locking and three-star door barrels for optimum security. Hardware, including hinges, is supplied by Total Hardware, meeting the high standards expected across the UK market.
Our manufacturing techniques are tailored around creating elite insulation, with our doors specifically designed to reduce heat loss. This is a key selling point for clients now, providing them with not only lower energy bills, but increased peace of mind too. Glazing (we offer both double and triple glazing), is sourced from Martindale’s in Blackburn and Glasscraft in Leeds.
We aim to respond to trade enquiries the same day and turn quotes around within 24 hours. Most orders are delivered within two weeks at competitive pricing, with free delivery across Leeds and the surrounding areas.
Yes. While we mainly serve Leeds, Selby and West Yorkshire, we accept trade orders from across the UK. Our installation team can fit locally or we'll supply only, whichever suits homeowners and trade clients best.

“Excellent service from start to finish. They made the process from colours to design easy, nothing was too much trouble. Lovely polite staff and fitters. Fitters turned up on time and finished to an exceptional standard (I am a perfectionist!) left my home clean and tidy and removed all old frames and doors. Couldn’t fault them at any stage and would highly recommend them. I would give more than 5* if I could.”
