About our fire stopping in Hurst

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Most enquiries involve fire stopping installed outside its tested range and damaged fire seals in risers and voids, across pipe penetrations, small duct penetrations where the tested detail allows and service gaps in risers. Whether you call it commercial sealant work, mastic application or joint sealing, in Hurst it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Hurst, 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.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. If others near Hurst need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Let building users know which areas are affected
  • Flag any permit to work we’ll need
  • Send asbestos survey details if the building is pre-2000

Advice

What happens if it’s left?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Older rural buildings around Hurst move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

A quote for service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

Questions we’re asked in Hurst

Can you work on a hospital site such as Wokingham Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Hurst?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Do you work in Hurst?

Yes. We cover Hurst, and the simplest way to start is to call 01277 525 020 or use the quote form.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Fire stopping in Hurst: the local picture

At about 33 miles from central London, Hurst is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

For a hospital such as Wokingham Hospital, which lies south of Hurst, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. For an estates team at a campus like University of Reading, which lies north-west of Hurst, summer M&E works are usually followed by a round of penetration sealing. In a school such as St Nicholas Church of England Primary, fire-rated sealant goes in around service penetrations where it is specified.

Different surfaces, different methods

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables, so we check before sealing.

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Plastic pipes whose detail calls for a collar or wrap
  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals

If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Surfaces we seal

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

What affects the price in Hurst

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Backing rod, priming and other preparation
  • Phasing around occupants

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Details that help us quote

We can often quote from photographs and a few details. Please tell us:

  • Your programme or deadline
  • Photos of the joints, close up and from further back
  • The postcode of the building
  • Anything awkward about access or site hours

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
