How we handle fire stopping in Canonbie

Facilities managers in Canonbie often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with fire-rated sealant that has cracked or shrunk back and unsealed joints where partitions meet the slab, we can put it right, whatever the surface. For commercial sealant work in Canonbie, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places such as Canonbie, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Maintenance after handover

Cleaning and maintenance staff play a part too. Share these points with them:

  • Get seals inspected before ceilings and boxing close
  • Agree the fire-stopping specification before services go in
  • Flag new cables with no seal around them
  • Check with the data sheet before painting over fire sealant

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Tell us who will meet us and how to get in at your building near Canonbie. That goes into the plan alongside the quote.

  1. We start with your penetration schedule, drawings or specification.
  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. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

What we need from you

  • Tell us your opening times and when work is allowed
  • Agree which areas must stay open
  • Make sure the joints can be reached

Quotes

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Related advice

Canonbie: questions and answers

Is a hospital such as Thomas Hope Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Canonbie too far out for you?

Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is the work guaranteed?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

What about RAMS and site documents?

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

Which standards are fire seals tested to?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested.

Will you write the fire-stopping specification?

No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it and point out anything needing another product.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Different surfaces, different methods

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.

How the quote is worked out

What shapes the price:

  • The product specified
  • Backing rod, priming and other preparation
  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

What we need to price the job

A few photographs plus some basic facts will normally do. Please tell us:

  • The type of building and who uses it
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • A wide shot and a close-up of the area

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email the details over.

Leave it or put it right?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Canonbie before they leak.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why us?

  • Clear, fixed quotes
  • CSCS-carded applicators
  • Fully insured, including public liability cover
  • Work to your specification and the manufacturer’s guidance

Fire-rated sealing for Canonbie buildings

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, with products tested for that end use. We install fire-rated sealant to that tested detail where it is specified.

In a building such as Canonbie Parish Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a hospital such as Thomas Hope Hospital, 5.3 miles to the north of Canonbie, penetration sealing is normally phased ward by ward, with infection-control rules agreed first.

Signs you need fire stopping in Canonbie

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in and later need putting right.

Site and facilities staff are often the first to spot these:

  • Builders’ foam or ordinary silicone in compartment walls
  • Openings found when ceilings come down for a refit
  • Penetration schedules that need working through
  • Unsealed joints where partitions meet the slab

For a hotel such as Cross Keys Hotel (under half a mile south of Canonbie), penetration seals are worth checking after any refit or services upgrade.
