Passive fire protection · Southern England
Fire stopping, fire doors, compartmentation surveys and remedial works — surveyed properly, installed properly, and photographed so you can prove it.
Family-run, based in Marlow · Part of Pro Fire Safety Group

Who we are
We are a family-run business based in Marlow, working throughout southern England. Passive fire protection is all we do — the parts of a building that contain fire and smoke, rather than the alarms that detect it.
We survey, install and record the work, giving building owners, facilities teams, contractors and managing agents a clear evidence trail for insurers and auditors. We are the passive half of the Pro Fire Safety Group.
What we do
Every building relies on being divided into compartments that hold fire and smoke long enough for people to get out. Cables get pulled, ducts get cut in, doors get replaced — and those lines quietly stop working.
We find where that has happened, tell you honestly what has to be fixed first, and put it right with certificated systems and a record you can hand to an insurer or auditor.

This is what an average building looks like behind the ceiling tiles. Tap a hotspot to see the defect, then switch to after remedials.
Where buildings usually fail
Breaches are almost always inside risers, above ceilings and in plant areas — the places other trades work and nobody checks what they cut through.
How we work
Type of premises, compartmentation strategy, fire doors, and anywhere protection may have been disturbed. We look at what the building was designed to do before we judge what it does now.
Every defect located, photographed and rated, so you can see what is wrong and where. Nothing is recorded as a vague area — each item ties to a place in the building.
A costed schedule split into immediate, planned and monitor — so you can phase or budget it. We tell you what genuinely has to be done now and what can wait.
Works carried out with certificated systems and recorded for audit and handover. You finish with photographs, product details and a record that stands up to scrutiny.
