Fire stopping for commercial buildings in Vassa

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about fire seals cut back for extra cables and never reinstated and penetration schedules that need working through, across joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows. Whoever orders the work in Vassa, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places such as Vassa, 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’re clear about what is covered before work starts.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Fire risk assessments, a job for a competent assessor
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Large openings beyond what any sealant detail covers

If in doubt, speak to us on 01277 525 020 or use the quote form and we’ll say what we think.

Where we work in Vassa

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

Common questions from Vassa clients

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

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.

Can you produce the fire-stopping design for a job in Vassa?

No, that sits with the designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

What do you charge?

Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or use the quote form with a description of the work.

How many days will you need on site?

It depends on the scope, though a typical visit usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you work in Vassa?

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

Surface by surface

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits.

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Travel to smaller Scottish places like Vassa is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Send your site hours and access windows
  • Have the specification and drawings to hand
  • Agree which areas must stay open

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Removal of failed or old sealant
  • The total length or number of joints
  • Working within restricted access windows
  • Location, for remote and island sites

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

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

  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • Any dates the work must fit around
  • The type of building and who uses it

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email the details over if you’d rather talk the job through.

Fire-rated sealing for Vassa buildings

Work on Vassa has to fit the ferry timetable and the forecast. We need the specification and a count of penetrations before we sail. 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, with products tested for that end use. We install what’s specified, to the product’s tested detail.

Around Vassa, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product. For any site around Vassa, we work to the specification and the manufacturer’s installation guidance, leaving design and sign-off with the designer.

Vassa is in the Shetland Islands. Across the ZE2 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our the Shetland Islands coverage takes in 63 places, from busy centres to rural villages.

Work on service penetrations is covered throughout ZE2, whatever the building. Just outside Vassa, we also work in Dury (4 miles north), Gott (5 miles south-west), Kalliness (5 miles south-west), Veensgarth (6 miles south-west) and Heogan (6 miles south). A short drive away, we cover Lerwick (7 miles south), Sound (8 miles south), Scalloway (9 miles south-west) and Brae (11 miles north-west). Where a site is remote or on an island, we plan travel and materials carefully, so the full address helps from the start.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Commercial clients in Vassa

We work for building owners and managing agents on everything from one building to a spread of sites around Vassa. One quote can cover more than one site, which keeps the paperwork simple.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
