Should I repair or replace a fire door?

If the core of the door is sound, repair it. If it is cut down, broken through or panelled, replace it.

Closers, hinges, seals, small holes and damaged edges can all be repaired. The repair costs less than a new door and is usually done in one visit.

A door that has been cut down too far has lost the thickness it was tested with. The same goes for a door with panels or mouldings cut into it. Cutting a fire door that way can void its rating, and no repair brings the rating back. For those the answer is a plain certified doorset.

Not sure which side of the line yours falls on? Send photos of both faces and the top edge. We will tell you.
