Thanks Anthony,
I have done a assessment of my door. Original 1960 flat door
it is hollow not solid
the thin edge is only 1.5cm
ithas 2 rising butt hinges no self closure
it has no seals around door or letterbox
so in my opinion not up to standard, too much work to try and bring it up to standard required so in your opinion am I making the right decision to get a new composite FD30S door.
thanks just don’t want to waste money if I don’t need to.
