Fire stopping for Cairnryan sites

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

Fire stopping in Cairnryan

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. Site teams most often ask us about hidden openings found during inspections and builders’ foam or ordinary silicone in compartment walls, across service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Cairnryan it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Travel to smaller places like Cairnryan is planned so every penetration is sealed on one trip. Send the specification and photos of the openings, with sizes if you have them.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Signing off or certifying a building’s fire stopping
  • Reviewing a building’s overall fire safety
  • Construction that lacks the fire resistance the seal relies on

Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly.

Where we work in Cairnryan

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

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Leave fire sealant to cure fully before covering it
  • File the specified details where the next contractor can find them
  • Put resealing into every M&E and fit-out package
  • Report damaged or disturbed seals as soon as they’re spotted

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Why deal with it now?

A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Renewing every failing joint on one visit is the sensible approach for a place like Cairnryan. Send photos and we will quote for everything together.

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

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building near Cairnryan, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  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.

What we need from you

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Fire stopping in Cairnryan: the local picture

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, and products should be tested for their end use. We install what’s specified, to the product’s tested detail.

Wherever services are added at a hospital such as Galloway Community Hospital (4.7 miles south of Cairnryan) the compartment line has to be made good with the specified product. For a building such as Lochryan Church And Burial-Ground, new heating or data runs are the usual reason penetrations need sealing.

Cairnryan is about 4 miles north of Stranraer, in Dumfries and Galloway. We send applicators to Cairnryan for service penetrations, handled exactly as we handle every other area. We work across 139 places in Dumfries and Galloway, large and small. For work in that direction, see our Glasgow page (68 miles or so).

Business premises anywhere in DG9 are within our area. If your building is just outside Cairnryan, we cover Kirkcolm (3 miles west), Innermessan (3 miles south), Leswalt (4 miles south-west), Stranraer (4 miles south) and Aird (5 miles south).

Near you in Cairnryan

For rail, the closest station is Stranraer station, roughly 4 miles south of the centre. Nearby you’ll also find Galloway Community Hospital (4.7 miles south) and North West Castle (4.3 miles south). For a walk, there’s Loch Ree.

Questions we are asked in Cairnryan

Is Cairnryan too far out for you?

No. Places such as Cairnryan are covered as much as the big towns. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.

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

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. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it.
