About our fire stopping in Cock Marling

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. Most enquiries involve unsealed penetrations discovered above suspended ceilings and fire-stopping items raised at inspection or handover, across pipe penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. A single leaking joint is often how a building in Cock Marling first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Cock Marling, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly.

Joints and surfaces we work on

  • Small duct penetrations where the tested detail allows
  • Cable penetrations
  • Linear gaps at wall heads
  • Joints between fire-resisting walls and floors
  • Pipe penetrations
  • Service gaps in risers

Service penetrations in Cock Marling buildings

Central London is about 51 miles from Cock Marling. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

On estates like Jempson Trading Estate, 2.3 miles east of Cock Marling, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

What does the BS 476 change mean for fire-rated sealant in Cock Marling?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Can you work to our specification?

What affects the price in Cock Marling

Your fixed quote is built from the real scope. It allows for:

  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first
  • Phasing around occupants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

However big the job, these details speed things up:

  • Your programme or deadline
  • Drawings or a marked-up plan, if available
  • Any specification or named product
  • Anything awkward about access or site hours

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Our process

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a building around Cock Marling, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Point out parking and an unloading spot
  • Have the specification and drawings to hand
  • Tell us what induction or permit system the site runs

Advice

Building owners, agents and FMs in Cock Marling

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Common problems we fix in Cock Marling

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it.

If one of these sounds familiar, it’s time for a closer look:

  • Expanding foam used as fire stopping
  • Unsealed joints where partitions meet the slab
  • Old intumescent sealant that has split away
  • Openings left by services added after handover

For buildings in and around Cock Marling, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

What to look for in a quote

  • How the joint faces will be prepared and primed
  • Will RAMS and insurance details be available?
  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

What the job involves on each surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
