Fire stopping around St Mary's: what changes locally

Island jobs, St Mary's among them, are planned around the ferry and the forecast. With the specification and photos of the openings, the right fire-rated products travel with us. Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, with products tested for that end use. Our part is installing the specified fire-rated sealant to its tested detail.

For buildings in and around St Mary's, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail. Theatres, wards and plant rooms at sites like Balfour Hospital, 5.8 miles north of St Mary's, all have compartment walls crossed by services.

St Mary's is about 6 miles south of Kirkwall, in the Orkney Islands. St Mary's sits inside our coverage and the rest of the Orkney Islands, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across the Orkney Islands, 51 places are covered, St Mary's among them.

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. We cover commercial and managed buildings on Station Square, St Mary's Road and Storehouse Place and the roads nearby. Close to St Mary's, our area also takes in Upper Sanday (3 miles east), Burray Village (4 miles south), Toab (4 miles north-east), Grimness (5 miles south) and St Margaret's Hope (5 miles south). St Mary's is one of the busier places in the Orkney Islands, and its commercial and public buildings are all within our area. Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you call the office on 01277 525 020 or use the quote form.

About our fire stopping in St Mary's

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Site teams most often ask us about unsealed penetrations discovered above suspended ceilings and seals that don’t match their tested detail, across joints between fire-resisting walls and floors, pipe penetrations and cable penetrations. Facilities teams, main contractors and managing agents in St Mary's tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Travel to smaller places like St Mary's 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.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Surface by surface

Metal pipes

Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.

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.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

How a job runs

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Where we can, we combine work around St Mary's with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  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. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance
  • Point out parking and an unloading spot

Getting a fixed quote

Advice

What affects the price in St Mary's

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

  • How much existing material needs removing
  • How accessible the joints are
  • The site’s rules and procedures
  • Travel to remote or island sites

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • Asbestos survey details if the building is older
  • Clear photographs of the problem areas
  • Specification clauses that apply
  • Approximate linear metres or a joint schedule

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’ll fill any gaps with a visit.

Common questions from St Mary's clients

How do the Scottish rules apply to fire-rated sealing in St Mary's?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Do you work on the island where St Mary's is?

Yes, St Mary's is within the area we cover. We work across every Scottish council area. Ferry times and the weather set the plan, so we ask for photographs and a full list first.

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. Indoors, the weather is rarely a problem.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Are you insured?

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

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

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.

Why act early in St Mary's

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, 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.
