Fire stopping across Cairston

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Fire stopping in Cairston, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about openings found when ceilings come down for a refit and fire-rated sealant that has cracked or shrunk back, across cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in Cairston from the first photos to the final walk-round, for single jobs and planned programmes alike.

Travel to smaller places like Cairston 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. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Questions about Cairston

Can you work around term dates at a campus such as Robert Gordon University Orkney Project?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

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

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.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Building owners, agents and FMs in Cairston

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Cost factors for service penetrations

Each job is priced on its own details. The main factors are:

  • Specialist products, such as fire-rated or hygienic sealants
  • Working within restricted access windows
  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements

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.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Photos of the joints, close up and from further back
  • The product your specification calls for
  • Whether the building will be occupied during the work
  • Any dates the work must fit around

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Do you need fire stopping in Cairston?

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it.

Typical triggers for a call:

  • Hidden openings found during inspections
  • Damaged fire seals in risers and voids
  • Open linear gaps along the top of fire-resisting walls
  • Penetration schedules that need working through

In a school such as stromness primary school, fire-rated sealant goes in around service penetrations where it is specified.

Questions to ask before you book

  • Their approach to joint depth and backing
  • Can the work be phased to keep areas open?
  • How they handle RAMS and site documents
  • The named product and why it was chosen

Choosing a commercial sealant contractor

How a job runs

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 handed back before we move to the next. Jobs near Cairston are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  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. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance
  • Clear stock, furniture or equipment away from the joints

Request a quote

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

Fire stopping in Cairston: the local picture

A 2-mile radius around Cairston takes in several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Work on Cairston has to fit the ferry timetable and the forecast. We need the specification and a count of penetrations before we sail.

Hotels such as The Stromness Hotel, 1.4 miles south-west of Cairston, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. For an estates team at a campus like Robert Gordon University Orkney Project (1.4 miles south-west of Cairston), summer M&E works are typically followed by a round of penetration sealing.

Cairston is about 11 miles west of Kirkwall, in the Orkney Islands. We cover Cairston, with the same fixed quotes and 12-month guarantee as everywhere else. Cairston is one of 51 places in the Orkney Islands on our list.

We take on service penetrations across the KW16 postcode area, for business premises of every kind. Sites close to Cairston are covered too, including Stromness (1 mile south-west), Clouston (2 miles east), Stenness (2 miles east), Wasbister (3 miles north) and Grimeston (4 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.

Other landmarks nearby include Stromness Museum (1.7 miles south-west). Green spaces nearby include Loch of Stenness and Brodgar RSPB Reserve.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Fire doors, dampers or other fire safety equipment
  • Gaps in walls that were never built as compartment walls
  • Plastic pipes whose detail calls for a collar or wrap

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly before you book.

What we seal

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

Why act early in Cairston

A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Around smaller places like Cairston, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why appoint us

  • Our applicators hold CSCS cards
