What we do

Replace self-closer · FD-114£160

Fire door FD-114’s self-closer no longer closes the door fully — a door that can’t close itself can’t hold back smoke, and BS 8214 requires it to.

Ease & adjust fire door · FD-203£85

FD-203 is binding on its frame and doesn’t close into its rebate — we re-hang and adjust it so it seals the way it was designed to.

Replace intumescent strips ×4£120

The heat-expanding seals on four doors are damaged — they’re what stops smoke and fire passing round the door edge, so they must be replaced.

How much remedial work walks out the door?

Your engineers already spot the faults. Without a system that turns findings into quotes, most of it never gets priced. Move the sliders — the maths is live.

How we build

Fast to build. Hard to break.

Built quickly, then stress-tested, security-hardened and independently verified before it ever touches your data.

01 · SCOPE

Map the operation

We learn how your business actually runs before a line of code — the workflow, the standards, the gaps.

02 · DESIGN

Architect it right

Data model, security and look-and-feel — designed to be lived in daily, not demoed once.

03 · HARDEN

Stress-tested & secured

Penetration-tested, load-tested and independently cross-verified — hardened to enterprise security standards before it goes live.

04 · SCALE

Live & growing

Deployed, supported and extended as you grow — we run it, keep it sharp and scale it with you.
