Fire Door Surveys & Inspections

A fire door is only fire-rated when its frame, hardware, seals and gaps are all correct. Most fail on at least one.

Overview

Fire doors hold back fire and smoke long enough to evacuate the building. Under Regulation 10 of the Fire Safety (England) Regulations 2022, Responsible Persons of residential buildings over 11 metres must check fire doors in communal areas at least every 3 months, and use best endeavours to check flat entrance doors at least every 12 months.

What we do

  • FDIS-qualified inspections of every fire-rated door set.
  • Photographic report, asset tag, defect register and prioritised remediation plan.
  • Replacement of failed door sets with third-party certified products (BWF Certifire / BM TRADA).
  • Intumescent seal, smoke seal and ironmongery upgrades.

Why this matters

Common defects — excessive gaps, missing intumescent strips, painted-over hinges, unrated closers — render the entire door non-compliant. Post-Grenfell, this is one of the highest enforcement focus areas in the country.

Frequently asked questions

Typically 2–4 mm at the top and sides. At the threshold, follow the door manufacturer’s installation instructions and keep the gap as small as practicable; where smoke control is required the gap should not exceed 3 mm, or the threshold should be sealed.
