How long does a fire door repair take?

Most repairs take 30 to 90 minutes a door. Half a day if the frame has moved.

An adjusted closer is a quick job. New seals take a bit longer, because the old ones have to come out and the groove has to be cleaned first.

A frame that needs repacking is the long one. The architraves come off, the frame is reset and fixed, foam goes in behind it and everything goes back.

On a block or a school, one carpenter gets through several doors in a day. A single flat door still means a van and a trip from Luton, which is why the first door costs more than the tenth.
