Fire stopping near Sayers Common

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

From enquiry to sign-off

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Sayers Common need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Share your working hours and any access restrictions
  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints

How we handle fire stopping in Sayers Common

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. Most enquiries involve open linear gaps along the top of fire-resisting walls and damaged fire seals in risers and voids, across cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors. Most enquiries from Sayers Common start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Sayers Common 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.

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

Service penetrations in Sayers Common buildings

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. What we install is set by the specification, and it goes in to the tested detail. Sayers Common lies roughly 38 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.

Offices at parks like Kings Business Centre, under half a mile to the west of Sayers Common, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Large healthcare estates like The Dene Hospital, 1.8 miles north-east of Sayers Common, change their services often, so penetration seals are worth checking after M&E work.

Sayers Common is about 3 miles west of Burgess Hill, in West Sussex. Commercial clients in Sayers Common can call on us for service penetrations, as part of our coverage of West Sussex.

Different surfaces, different methods

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range.

Why it’s worth doing now in Sayers Common

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is usually a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Converted and older buildings near places like Sayers Common tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why appoint us

  • Failed material removed, not covered up
  • Commercial sealant work since 2005
  • 12-month guarantee on workmanship
  • Public liability insurance in place

Do you need fire stopping in Sayers Common?

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

Most enquiries start with something like this:

  • Builders’ foam or ordinary silicone in compartment walls
  • Openings found when ceilings come down for a refit
  • Unsealed joints where partitions meet the slab
  • Fire-stopping items raised at inspection or handover

For a school such as Albourne CofE Primary School, penetration sealing fits best at the end of the summer works.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • What the guarantee covers, and for how long
  • Are they CHAS accredited or on Constructionline?
  • Is the sealant right for the movement and the substrate?

How to choose a sealant contractor

Common questions from Sayers Common clients

What does the BS 476 change mean for fire-rated sealant in Sayers Common?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Does your area include sites such as Kings Business Centre, near Sayers Common?

Yes, sites like Kings Business Centre are within our area, along with the rest of Sayers Common. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What do you charge?

We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Can you handle several sites?

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.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Treat an open penetration as a priority repair
  • Leave fire sealant to cure fully before covering it
  • Arrange inspection before areas are covered up

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.
