Fire stopping in Clivocast, done properly

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on linear gaps at wall heads, service gaps in risers and joints between fire-resisting walls and floors, and what we’re called in for most is unsealed penetrations discovered above suspended ceilings and openings left by services added after handover. A single leaking joint is often how a building in Clivocast first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places such as Clivocast, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Those penetrations are closed with the product the specification names, built up as tested.

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 are clear about what is covered before work starts.

When to call us in Clivocast

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it and has to be removed.

Common reasons buildings call us in:

  • Builders’ foam or ordinary silicone in compartment walls
  • Unsealed penetrations discovered above suspended ceilings
  • Penetration schedules that need working through
  • Seals disturbed by maintenance and left open

Buildings near Clivocast get the fire-rated product that’s specified, installed to its tested detail.

Questions to ask before you book

  • Their public liability cover
  • Which product they’ll use, and why it suits the joint
  • Are they CHAS accredited or on Constructionline?
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

What happens if it’s left?

An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Resealing early avoids that.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why us?

  • Old sealant cut out, never sealed over
  • 12 months’ guarantee on every job
  • Specification-led, product-correct work
  • Over 20 years of commercial sealing

Compartments and services around Clivocast

For an island location such as Clivocast, work is planned around ferry crossings and the weather. The specification and photos of each penetration let us bring the right products first time. 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, using products tested for the way they’re used. Our part is installing the specified fire-rated sealant to its tested detail.

Older community buildings such as Uyeasound Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Clivocast is in the Shetland Islands. Commercial clients in Clivocast use us for work on service penetrations, as part of our coverage of the Shetland Islands. 63 places across the Shetland Islands fall within our area, Clivocast among them.

Commercial sites across ZE2 are covered for service penetrations. Just outside Clivocast, we also work in Cullivoe (4 miles north-west), Baltasound (6 miles north), Houbie (6 miles south), Camb (7 miles south-west) and Mid Yell (8 miles south-west). Where a site is remote or on an island, travel and materials need planning ahead, so the full address helps from the start.

FAQs: Clivocast

Will you design a fire-stopping scheme for our building in Clivocast?

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 the Scottish rules apply to fire-rated sealing in Clivocast?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. Design sits with the designer and the verifier; installation to the tested detail is our part.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Aftercare for building managers

Once the work is signed off, these steps help:

  • Look above ceilings when tiles are lifted for other jobs
  • Don’t let anyone top up a fire seal with the wrong product
  • Settle who seals which penetrations at the start of a project
  • Make fire stopping part of every scope that crosses a fire-resisting wall

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.

Different surfaces, different methods

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Clivocast, we aim for one trip, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Point out any areas we must not close
  • Send your site hours and access windows
  • Arrange parking or a loading space
