Fire stopping across West Sussex: what to expect

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in West Sussex. We work on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and what we are called in for most is openings found when ceilings come down for a refit and openings left by services added after handover.

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What you will pay

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Local landmarks in Crawley

In Crawley, that means premises near Friary Church of St Francis and St Anthony, St Wilfrid's Catholic School and Tilgate Park. Other local landmarks include The George Hotel (under half a mile north), Three Bridges Junior School (under half a mile south-east) and St Francis of Assisi Catholic Primary School (under half a mile south-east). There’s a railway station in Crawley itself: Crawley station. A little further out are Crawley Hospital (0.5 miles north-west) and County Mall (less than half a mile north-east). For a walk, there’s Tilgate Lake.

Fire stopping across West Sussex: the area picture

Hospitals, schools, care homes, offices and blocks across West Sussex all rely on fire-resisting walls and floors. We install fire-rated and intumescent sealant where it is specified, around service penetrations and linear gaps, to the tested detail.

We work across Greater London and the South East counties, and every job in West Sussex starts with access, parking and site rules. On the coastal side of West Sussex, sea-facing elevations normally show failed joints first.

Crawley: Hospital estates such as Crawley Hospital, 0.5 miles north-west of Crawley, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Shop fits in centres such as County Mall, less than half a mile north-east of Crawley, can bring new services through fire-resisting walls between units, which then need the specified seal.

Different surfaces, different methods

Risers and ceiling voids

Voids hide a lot of unsealed openings. We follow your schedule area by area.

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones normally call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

Leave it or put it right?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Common problems we fix in West Sussex

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.

Most enquiries start with one or more of the following:

  • Head-of-wall gaps with no fire seal
  • Fire-stopping items raised at inspection or handover
  • Unsealed penetrations discovered above suspended ceilings
  • Old intumescent sealant that has split away

What affects the price in West Sussex

There’s no standard rate for sealant work, because every site is different. What we look at:

  • The size and state of each joint
  • How accessible the joints are
  • The site’s rules and procedures
  • Quantities, in metres or numbers

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Asbestos survey details if the building is older
  • What the building is and how it’s used
  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Common questions from West Sussex clients

Will fire-rated sealant work on every penetration?

No. It depends on the tested detail for that wall or floor and service. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we’ll tell you when that applies.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

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

No, and we won’t imply otherwise. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. Where it isn’t required, we install the specified sealant to the maker’s details.

What do BS EN 1366-3 and BS EN 13501-2 mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. The rating applies to the product as tested.

Do you seal openings left by new services?

Yes, provided a specification covers them. New services after M&E works often breach existing seals, and we reseal them to the specified detail.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or use the quote form. Include photos or drawings if you have them.
