About Rockfirepro Ltd

01Who We Are

Loughton, Essex

Passive Fire Protection You Can Trust

Rockfirepro Ltd is a specialist passive fire protection contractor based in Loughton, Essex. We deliver fire stopping, compartmentation and penetration sealing works across residential, commercial and public sector buildings throughout the UK.

We were founded with one clear objective: to deliver passive fire protection works to the highest possible standard - using only third-party tested and certified products, backed by full documentation that clients, building owners and regulators can rely on.

We believe that passive fire protection is not a box-ticking exercise. It is a life safety discipline. Each installation we carry out is treated with the seriousness it deserves - from the survey stage through to the final handover documentation.

Protecting What Matters

Fire stopping and compartmentation specialists committed to life safety and building compliance.

What that means on site

Anyone can say it. This is what actually happens to each penetration we seal.

  1. 01Sealed to a tested detail, not an approximation of one.
  2. 02Photographed before, during and after, with the product and operative recorded.
  3. 03Pinned to its exact spot on the drawing, so it can be found again years later.
  4. 04Written into a hash chain, so nothing can be quietly altered after sign-off.
  5. 05Handed over as a register the building keeps. Yours, not ours.

02Our Approach

Four steps

How We Work

From first contact to final documentation, we make the process straightforward and transparent.

  • 2.1

    1. Survey & Assess

    We carry out a thorough survey to understand the scope of works required and identify any existing deficiencies.

  • 2.2

    2. Confirm & Quote

    We confirm the tested detail and the certified product for each application from the project specification, and send a competitive quote.

  • 2.3

    3. Install & Record

    Our trained operatives carry out installations in line with manufacturer requirements and tested installation details.

  • 2.4

    4. Document & Certify

    Each job is fully documented with photographic evidence, product data sheets and our own installation certificates at handover.
