Fire stopping for Yapton sites

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

General trades versus a specialist

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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Fire stopping in Yapton

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Site teams most often ask us about unsealed joints where partitions meet the slab and hidden openings found during inspections, across pipe penetrations, linear gaps at wall heads and service gaps in risers. Facilities teams, main contractors and managing agents in Yapton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Buildings in a smaller place such as Yapton that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Surface by surface

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.

Linear joints

Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Approving the work on behalf of building control
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Fire doors, dampers or other fire safety equipment

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.

Surfaces we seal

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

Why deal with it now?

Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Signs you need fire stopping in Yapton

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Look out for the following:

  • Old intumescent sealant that has split away
  • Improvised or mixed-product fire seals
  • Seals disturbed by maintenance and left open
  • Expanding foam used as fire stopping

Campus buildings at universities such as University of Chichester (Bognor Campus) (3 miles south-west of Yapton) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Questions to ask before you appoint anyone

Questions about Yapton

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

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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.

Can you work around term dates at a campus such as University of Chichester (Bognor Campus)?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Are you insured?

Yes. We are fully insured, including public liability cover.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

Where services cross fire walls in Yapton

Several hotels sit less than 2 miles from Yapton. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Yapton is about 52 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Offices at parks like Orchard Business Park. (to the north of Yapton) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Theatres, wards and plant rooms at sites like Arundel and District Hospital (to the north-east of Yapton) all have compartment walls crossed by services.

Yapton is about 4 miles north-east of Bognor Regis, in West Sussex. We send applicators to Yapton for service penetrations. Yapton is one of 373 places in West Sussex on our list. We also cover Portsmouth, some 20 miles away.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. What matters most for a job in Yapton is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. We ask for the product and detail your designer has specified.
  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. 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

  • Arrange parking or a loading space
  • Make sure the joints can be reached
  • Have the specification and drawings to hand
