Fire stopping for Shripney sites

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

Fire stopping for commercial buildings in Shripney

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and fire sealant pulled out of the opening, on linear gaps at wall heads, service gaps in risers and pipe penetrations. A specialist sealant contractor works differently from a general builder: on jobs in Shripney, preparation and product choice get the time they need.

Around smaller places like Shripney, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What we’re called out for in Shripney

Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.

It’s worth sending us details if you spot any of the following:

  • Openings found when ceilings come down for a refit
  • Fire-stopping items raised at inspection or handover
  • Seals disturbed by maintenance and left open
  • Unsealed joints where partitions meet the slab

For a building at a site such as Saltbox Business Park. (less than half a mile south of Shripney), a check of penetration seals after each fit-out is good practice.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Will CSCS-carded applicators be on site?
  • Their public liability cover
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Backing rod, priming and other preparation
  • Any access equipment needed
  • The site’s rules and procedures
  • Location, for remote and island sites

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Your programme or deadline
  • The asbestos register, for older buildings
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or use the quote form to discuss it first.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For a building around Shripney, 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. 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.

Preparing the site

  • Make sure the joints can be reached
  • Explain the parking and delivery arrangements
  • Confirm the product named in the specification

Different surfaces, different methods

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Signing off or certifying a building’s fire stopping
  • Gaps in walls that were never built as compartment walls

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

  • Linear gaps at wall heads

Compartment walls and floors in Shripney

A 2-mile radius around Shripney takes in a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

For a hospital such as Bognor Regis War Memorial Hospital, 1.3 miles south of Shripney, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. Shop fits in centres such as Arun Retail Park (to the south of Shripney) can bring new services through fire-resisting walls between units, which then need the specified seal.

Shripney is about 2 miles north-east of Bognor Regis, in West Sussex. We cover commercial sites throughout Shripney, for single jobs and planned programmes alike. 373 places across West Sussex fall within our area, including Shripney. Our Portsmouth page has more on work in that area (18 miles or so).

Shripney: questions and answers

What happens to BS 476 references for fire stopping in Shripney?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is Shripney off your patch?

Not at all. Shripney is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Are you CHAS accredited and on Constructionline?

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

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
