How is a doorset installed?
The opening is prepared to the size and tolerances in the manufacturer's instructions. The frame is fixed with the specified fixings at the specified centres, packed where needed, and checked for square, plumb and twist. The gap between frame and wall is then sealed with a material covered by the evidence, which BS 8214:2026 now describes in more detail. Finally the leaf is adjusted, the closer is set and the assembly is tested before the architraves go on.
As standard, the work covers:
- Certificate references and photo record per opening
- Frame fixing and frame-to-wall gap sealing
- Closer set-up and close-and-latch testing
- Installation to the manufacturer's instructions

Questions from Sunbury-on-Thames
Do you work in Sunbury-on-Thames?
Yes, we take on certified fire doorsets in Sunbury-on-Thames and the surrounding area, including Walton-on-Thames and Hampton. Send your postcode and a few details and we'll come back with survey dates.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
How long do doorsets take to arrive?
Lead times depend on the manufacturer, size, finish and ironmongery. Standard sizes can be quick; bespoke sizes and finishes take longer. We give you the lead time with the quote and confirm it at order.
Are doorsets more expensive than a leaf?
The product costs more, but the labour is often lower and the result is better evidenced. Where a frame would need replacing anyway, a doorset is usually the better value.
