Fire stopping for Dornie sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping for commercial buildings in Dornie

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on small duct penetrations where the tested detail allows, service gaps in risers and joints between fire-resisting walls and floors, and the failures we are asked to look at most are fire sealant pulled out of the opening and improvised or mixed-product fire seals. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Dornie it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In smaller Scottish places like Dornie, 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.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

What we seal

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

For managing agents and facilities managers

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

Building owners and managing agents use us on everything from one building to a spread of sites around Dornie. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Cost factors for service penetrations

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

  • Which sealant the job calls for
  • Any access equipment needed
  • How much existing material needs removing
  • How much there is to seal

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Clear photos of the problem areas
  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • How the joints are reached, and at what height

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Fire stopping in Dornie: the local picture

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, and products should be tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail.

Where a unit on an estate such as Ardelve Industrial Estate, under half a mile to the north-west of Dornie, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Hotels such as Dornie Hotel (to the south-west of Dornie) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Dornie is in Highland. Looking for fire stopping in Dornie? We can help. Across Highland, 256 places are covered, Dornie among them.

We take on service penetrations across the IV40 postcode area, whatever the building. If your site is on St Duthac Drive, Rathad an Àite Mhòir and Francis Street or close by, send details and we will quote for service penetrations. Sites close to Dornie are covered too, including Carndu (1 mile north-east), Bundalloch (1 mile north-east), Auchtertyre (3 miles west), Reraig (4 miles west) and Inverinate (4 miles south-east). Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Tell us who will meet us and how to get in at your building near Dornie. That goes into the plan alongside the quote.

  1. We read the specification, drawings or penetration schedule you send 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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Confirm the product named in the specification
  • Send your site hours and access windows

FAQs: Dornie

Is Dornie off your patch?

Not at all. Dornie is within our area. We cover the whole of Scotland. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will you take on work at estates like Ardelve Industrial Estate, close to Dornie?

Yes. Estates, retail parks and business parks around Dornie, Ardelve Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

Do you have third-party installer accreditation for fire stopping?

No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we are not the right fit for that package.

Can you seal any opening with fire-rated sealant?

No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

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.

Signs you need fire stopping in Dornie

Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.

Clients typically get in touch after noticing one or more of the following:

  • Fire-stopping items raised at inspection or handover
  • Openings found when ceilings come down for a refit
  • Unsealed openings around new pipes and cables
  • Seals disturbed by maintenance and left open

Halls and meeting rooms at places like St Duthuc's Roman Catholic Chapel sometimes gain new services, and any compartment wall crossed needs the specified seal.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • Proof of insurance
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

Leave it or put it right?

The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. For buildings near Dornie, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why appoint us

  • Fully insured, including public liability cover
  • A fixed quote before work starts
  • 12 months’ guarantee on every job
  • Constructionline member for supplier checks
