Fire stopping across Aird Tong

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from one day to a planned run of visits, depending on the number of seals and the access. Tell us who will meet us and how to get in at your building near Aird Tong. That goes into the plan alongside the quote.

  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. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Move anything stored against the joints
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Quotes

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Fire stopping in Aird Tong

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about hidden openings found during inspections and damaged fire seals in risers and voids, across service gaps in risers, cable penetrations and pipe penetrations. A single leaking joint is often how a building in Aird Tong first comes to us: we look at the rest while we’re there and tell you what we find.

For a building near Aird Tong, we plan fire-rated sealing so it’s finished in one visit where possible. Photos of the gaps, the services and the wall or floor type help us bring the right products.

A 12-month guarantee applies to all our work in Na h-Eileanan Siar. Should something we installed fail, call 01277 525 020 or email us and we will come back to it.

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with
  • Reviewing a building’s overall fire safety

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Where we work in Aird Tong

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

Service penetrations in Aird Tong buildings

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. Where fire-rated sealant is specified, that’s what we install, to the tested detail. For an island location such as Aird Tong, work is planned around ferry crossings and the weather. Photos of each opening and the specification mean the right products make the trip.

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

Aird Tong (Gaelic: Aird Thunga) is in Na h-Eileanan Siar. We cover commercial sites throughout Aird Tong. We work across 87 places in Na h-Eileanan Siar, large and small.

Anyone looking for fire stopping in HS2 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. If your building is just outside Aird Tong, we cover Tong (1 mile west), Upper Coll (1 mile north), Steinis (2 miles south), Newmarket (2 miles south-west) and Bac (2 miles north-east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Around Aird Tong

A little further out are Western Isles Hospital (2.6 miles south-west) and Lewis Loom Centre (3.2 miles south-west). The countryside around Aird Tong includes Loch Àirigh na Lic.

How the job changes by surface

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we’ll never swap a specified collar for sealant.

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness first.

Common problems we fix in Aird Tong

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in.

Most enquiries start with something like this:

  • Damaged fire seals in risers and voids
  • Fire-rated sealant that has cracked or shrunk back
  • Penetration schedules that need working through
  • Openings found when ceilings come down for a refit

Wherever services are added at a hospital such as Western Isles Hospital (2.6 miles south-west of Aird Tong) the compartment line has to be made good with the specified product.

Choosing a commercial sealant contractor

Why deal with it now?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. Around smaller places like Aird Tong, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

FAQs: Aird Tong

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

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. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Can you work on a hospital site such as Western Isles Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

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.

How do we ask for a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

What sets the cost

To price the job, we consider:

  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Quantities, in metres or numbers
  • Joint width, depth and condition

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • A wide shot and a close-up of the area
  • The type of building and who uses it
  • Any dates the work must fit around
  • Access details, including height

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or use the quote form.
