Your questions answered
Can you work around tenants or staff?
Yes. We phase work in occupied buildings and keep escape routes available. Each door is planned to be removed and replaced the same day; if that isn't possible, the opening is made secure and we tell you in advance.
Which rules apply in Dorset?
Doors are specified to Approved Document B (England) and your fire risk assessment or fire strategy. We confirm the rating of each door at survey.
Will I get certificates for the doors fitted?
Every doorset is listed in your handover pack with the manufacturer's certificate reference, plus an installation record and photos.
Are FD120 doors always steel?
Most are, though some specialist timber and composite systems hold longer ratings. The evidence for the exact configuration is what counts.
