I have a fire door with a gap between about 3 and 4mm round the edges, but the cold smoke brush seal doesn't touch the door. I'd say the gap is about 1mm. Is that acceptable? Thanks in advance.

My mother has recently bought a new build flat. The block of 14 flats was signed off in June 2022 by building control. I noticed the other day that her front door has about an 8mm uniform gap on the door latch edge. The hinge edge is about 2 to 3mm. The intumescent strip with brush seal is fitted to the frame and as you'd expect doesn't get close to touching the door latch edge. The door is an expensive looking veneered redwood door, so adding a lip is not going to be aesthetically acceptable. The frame is a white painted softwood door lining with supplanted door stop and I think is likely to be what is modified. The company that built the property have an 'odd job' man who has dealt with a number of snagging items to date. When I report the problem I suspect he will come along and rectify it but I'm concerned that it will not be done in a way that keeps the fire resisting integrity of the door frame. Any advice on what would be an acceptable repair and who I could ask to check the work afterwards would be appreciated.
