Where services cross fire walls in Isbister

Work on Isbister has to fit the ferry timetable and the forecast. With the specification and photos of the openings, the right fire-rated products travel with us. 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, with products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

Buildings near Isbister get the fire-rated product that’s specified, installed to its tested detail. Wherever the building is near Isbister, design and sign-off of fire stopping sit with the designer, fire engineer or building control; we install what has been specified.

Isbister is about 6 miles north-west of Kirkwall, in the Orkney Islands. Isbister sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Isbister is one of 51 places we cover in the Orkney Islands.

If you need fire stopping in KW17, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

About our fire stopping in Isbister

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the usual reasons a site gets in touch are penetration schedules that need working through and improvised or mixed-product fire seals. Most enquiries from Isbister start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Travel to smaller places like Isbister is planned so every penetration is sealed on one trip. Photos of the gaps, the services and the wall or floor type help us bring the right products.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Building owners, agents and FMs in Isbister

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, plus a 12-month guarantee.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Our process

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs near Isbister are often grouped with others in the same area. Let us know if your dates have any give.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close
  • Confirm the product named in the specification

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Questions about Isbister

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

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 work on the island where Isbister is?

Yes. Every Scottish council area is within our area, and that includes island locations such as Isbister. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Maintenance after handover

To get the most from the new sealant:

  • Arrange inspection before areas are covered up
  • Keep product data and details in the fire safety file
  • Check with the data sheet before painting over fire sealant
  • Treat an open penetration as a priority repair

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.

Why it’s worth doing now in Isbister

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Around smaller places like Isbister, 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 the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Why appoint us

  • CHAS accredited contractor
  • Fully insured, including public liability cover
  • One number for every site we cover
  • Commercial sealant work since 2005

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Signing off or certifying a building’s fire stopping
  • Reviewing a building’s overall fire safety
  • Walls or floors that aren’t fire-resisting to begin with

If you are not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer.

Surfaces we seal

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