General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

About our fire stopping in Lochboisdale

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. The enquiries we see most involve old intumescent sealant that has split away and head-of-wall gaps with no fire seal, on service gaps in risers, pipe penetrations and cable penetrations. A single leaking joint is often how a building in Lochboisdale 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.

In smaller Scottish places like Lochboisdale, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. 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.

Where services cross fire walls in Lochboisdale

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 proprietary products, intumescent ones included, tested for their end use. We install what’s specified, to the product’s tested detail. Work on Lochboisdale has to fit the ferry timetable and the forecast. With the specification and photographs of the openings, the right fire-rated products travel with us.

Hotels such as Lochboisdale Hotel (less than half a mile north-east of Lochboisdale) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Lochboisdale is in Na h-Eileanan Siar. Any commercial site in Lochboisdale is covered. We work across 87 places in Na h-Eileanan Siar, from busy centres to rural villages.

Anyone looking for fire stopping in HS8 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. If your site is on Braehead, Calabhaigh and Kenneth Terrace or close by, we can quote for service penetrations. If your building is just outside Lochboisdale, we cover Loch Baghasdail (1 mile north), Dalabrog (2 miles north-west), Rubha Ban (5 miles south), Eòlaigearraidh (9 miles south-west) and Cuidhir (12 miles south-west). Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you call the office on 01277 525 020 or use the quote form.

Common questions from Lochboisdale clients

What do Scotland’s building standards say about service penetrations in Lochboisdale?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

Do you design the fire stopping for buildings in Lochboisdale?

No, that sits with the designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you handle several sites?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

How much does the work cost?

We don’t publish prices, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

What we’re called out for in Lochboisdale

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Clients normally get in touch after noticing something like this:

  • Openings found when ceilings come down for a refit
  • Expanding foam used as fire stopping
  • Seals disturbed by maintenance and left open
  • Unsealed joints where partitions meet the slab

For buildings in and around Lochboisdale, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Questions to ask before you appoint anyone

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Include service cupboards in routine inspections
  • Arrange inspection before areas are covered up
  • Ask which product is in place before decorating
  • Treat an open penetration as a priority repair

New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Travel to smaller Scottish places like Lochboisdale is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  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 first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Flag any permit to work we’ll need

Leave it or put it right?

Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. 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.
