Constructionline Gold AccreditedPassive Fire Protection Specialists
The hard part of fire-stopping isn’t the install — it’s proving it years later when an assessor asks. We seal to the tested detail and photograph, map and log every penetration we seal to a verifiable register — so if a seal you’re responsible for is ever inspected, the evidence is already on file: you can show exactly what went in and how, instead of scrambling to reconstruct it. Essex, London & UK-wide.
Why Choose Rockfirepro
Passive Fire Protection Services
We deliver a complete range of passive fire protection solutions, ensuring your building meets fire safety regulations and protects occupants.
Fire Stopping Works
Expert installation of fire stopping systems to seal gaps, penetrations and joints in fire-rated walls, floors and ceilings — preventing the spread of fire and smoke.
Fire Compartmentation
Maintaining the integrity of fire compartments is critical to life safety. We restore and install compartmentation barriers to ensure compliance with building regulations.
Penetration Sealing
Sealing pipe, cable and duct penetrations through fire-rated elements using certified intumescent products — tested to the highest industry standards.
Linear Gap Sealing
Sealing linear gaps at wall-to-wall, wall-to-floor and wall-to-ceiling interfaces to maintain the integrity of the fire compartment.
Inspections & Surveys
Detailed passive fire protection surveys across your entire building, identifying deficiencies and providing a prioritised remediation plan with full documentation.
Intrusive Compartmentation Surveys
Opening up ceiling voids, risers and service cupboards to inspect the compartment line where breaches actually happen — every defect photographed, located on the drawing and priced for remediation.
Cavity Barriers
Installation of small and large cavity barriers — including FireFly flexible barrier systems — to close off concealed voids and ceiling, roof and floor spaces, preventing the hidden spread of fire and smoke.
Remediation Works
Putting right failed or defective fire-stopping — restoring compartmentation, sealing missed penetrations and correcting non-compliant work — with every fix photographed and logged to a verifiable record.
Documentation & Certification
A complete, verifiable record for every job — each seal photographed, mapped to the drawing and logged — so your golden-thread evidence is inspection-ready, not scrambled together at handover.
Try to fake this record.
Watch it catch you.
Every seal we install is written to a tamper-evident register on Assaya — the software we built. Change the fire rating on the first seal and watch the whole chain break. This is exactly why our fire-stopping holds up when your client’s assessor comes calling.

Tamper affordance: change SA-014’s rating from EI120 to EI60.

Verify us on the public record
A fire-stopping claim is only worth the proof behind it — so here’s ours. Where an official public register exists, we link you straight to it — Companies House, the ICO, the Cyber Essentials register. Constructionline has no public per-member register, so for that one we show you the certificate ourselves.

What the badges actually mean: Constructionline Gold = independently prequalified on finances, insurance and quality, with our health & safety competence assessed under a UKAS-accredited SSIP scheme; Cyber Essentials = the NCSC’s government-backed cyber-security standard; Golden-Thread Ready = our records are structured for the Building Safety Act’s information duties — we don’t claim BSA “certification,” because there is no such scheme. Rockfirepro Ltd is a UK company with a named director on the public record; the Companies House link above shows exactly who stands behind the work.
