Fire stopping in Aithsetter

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Site staff or a sealant specialist?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Fire stopping for commercial buildings in Aithsetter

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. The enquiries we see most involve unsealed openings around new pipes and cables and improvised or mixed-product fire seals, on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. For commercial sealant work in Aithsetter, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places such as Aithsetter, 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.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Common questions from Aithsetter clients

Do you design the fire stopping for buildings in Aithsetter?

No, that sits with the designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.

How do Scotland’s building standards affect fire-rated sealant in Aithsetter?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months.

Do you cover Aithsetter?

Yes. We take on work across Aithsetter, with one number for every area we cover.

Can the building stay open while you work?

Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How many days will you need on site?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Surface by surface

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.

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.

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Location, for remote and island sites
  • Which sealant the job calls for
  • The size and state of each joint
  • Whether old sealant has to be cut out first

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • The site address and postcode
  • When you need the work done
  • Drawings or a marked-up plan, if available
  • The asbestos register, for older buildings

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or send photos by email.

Signs you need fire stopping in Aithsetter

When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Most enquiries start with something like this:

  • Head-of-wall gaps with no fire seal
  • Fire-stopping items raised at inspection or handover
  • Improvised or mixed-product fire seals
  • Damaged fire seals in risers and voids

Around Aithsetter, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

Comparing quotes

  • How long is the guarantee, and what does it include?
  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Fire stopping in Aithsetter: the local picture

Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, and products should be tested for their end use. We install fire-rated sealant to that tested detail where it is specified. For an island location such as Aithsetter, work is planned around ferry crossings and the weather. We need the specification and a count of penetrations before we sail.

Wherever the building is near Aithsetter, design and sign-off of fire stopping sit with the designer, fire engineer or building control; we install what has been specified.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Where we can, we combine work around Aithsetter with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  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.

What we need from you

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000
