Why frames fail inspections
Many fire door problems start with the frame: softwood linings too thin for the door, frames cut back to fit a previous door, frames loose in the wall, or gaps behind the architrave stuffed with ordinary foam or left open. A perfect leaf hung in a frame like that cannot be relied on.

Questions
Do you provide fire door frames across County Londonderry?
Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
Why do you photograph the frame before fitting architraves?
Because the fixing and sealing are hidden once the architraves go on. Photographs give you evidence that the hidden work was done correctly.
Can a new frame be fitted to my existing door?
Sometimes, if the frame is compatible with the door's certification. Often it is simpler and better evidenced to replace the whole doorset.
