What to check before you buy
Composite doors vary widely. The certification must cover the whole doorset as supplied: the core, skin, frame, glazing, letterplate, viewer and every item of hardware. Ask to see the certificate and the installation instructions, and check that the door's configuration, such as a side panel or glazed panel, is actually covered. BS 8214:2026 now includes maintenance guidance for composite and metal doors, reflecting how common they have become.

Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
Can I add a letterbox to a composite fire door?
Only if the letterplate is part of the certified doorset. Cutting one in afterwards would compromise the door's fire performance.

Yes, as flat entrance doors they need a self-closing device that closes and latches them. This can be overhead or concealed, depending on the certified options.
