Fire stopping near Broadford

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Broadford, done properly

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on pipe penetrations, linear gaps at wall heads and service gaps in risers, and what we’re called in for most is service penetrations left open after M&E works and snag lists that include open service penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Broadford is the same: the right product in a properly prepared joint.

Smaller places such as Broadford still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Our workmanship is guaranteed for 12 months, in Broadford as everywhere else we work. If our installation lets you down in that time, we return and fix it.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Broadford, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Point out parking and an unloading spot
  • Point out any areas we must not close
  • Make sure the joints can be reached

Getting a fixed quote

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email drawings and photos.

When to call us in Broadford

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

Look out for the following:

  • Fire-stopping items raised at inspection or handover
  • Fire stopping installed outside its tested range
  • Unsealed penetrations discovered above suspended ceilings
  • Service penetrations left open after M&E works

Workshops and IT rooms at colleges like Guildford College, 2.3 miles to the north of Broadford, are re-serviced often, leaving penetrations to seal.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their pre-qualification and accreditations
  • How the existing material will be dealt with

How to choose a sealant contractor

Questions we’re asked in Broadford

Is a hospital such as Mount Alvernia Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will you work in a care home in Broadford without moving residents out?

Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.

Are you members of a third-party fire-stopping installer scheme?

No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we will say so straight away rather than waste your time.

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Do you certify or sign off fire stopping?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Surface by surface

Small ducts

Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Flag new cables with no seal around them
  • Agree the fire-stopping specification before services go in
  • Check risers and ceiling voids after each round of works

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Owners, agents and contractors

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Broadford can form part of a wider programme across Surrey.

Central London is about 29 miles from Broadford. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. The 2 miles around Broadford include three care or nursing homes. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified.

For an estates team at a campus like University of Surrey - Stag Hill Campus (2.3 miles north of Broadford), summer M&E works are usually followed by a round of penetration sealing.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
