Fire stopping near Clouston
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Travel to smaller Scottish places like Clouston is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. External joints need a dry spell as well.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Tell us your opening times and when work is allowed
- Point out parking and an unloading spot
- Clear stock, furniture or equipment away from the joints

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Fire stopping for commercial buildings in Clouston
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. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you’re dealing with seals disturbed by maintenance and left open and openings found when ceilings come down for a refit, we can help, on service gaps in risers, joints between fire-resisting walls and floors and pipe penetrations alike. A specialist sealant contractor works differently from a general builder: in Clouston, that means joint design, primers and backing rod as standard.
In smaller Scottish places like Clouston, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Those penetrations are closed with the product the specification names, built up as tested.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Plastic pipes whose detail calls for a collar or wrap
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly.
What we seal
- Linear gaps at wall heads
- Cable penetrations
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Leave it or put it right?
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. For buildings near Clouston, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Common questions from Clouston clients
Can work at a site such as Robert Gordon University Orkney Project fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Will you travel to Clouston on the island?
Yes. Islands are part of our area, Clouston included. We group island work where we can and plan around the crossings.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Do you certify or sign off fire stopping?
No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed and agree any further records when we quote.
Compartment walls and floors in Clouston
Being on an island, Clouston means planning around ferry times as well as the weather. Photos of each opening and the specification mean the right products make the trip. 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, and products should be tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.
For an estates team at a campus like Robert Gordon University Orkney Project, 3.1 miles to the south-west of Clouston, summer M&E works are usually followed by a round of penetration sealing. Hotels like Standing Stones Hotel (under half a mile north of Clouston) are refurbished in phases, and each phase can open up compartment walls. In a building such as Stenness Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Clouston is about 9 miles west of Kirkwall, in the Orkney Islands. Our applicators travel to Clouston for work on service penetrations. We work across 51 places in the Orkney Islands, large and small.
We cover the KW16 postcode districts. Just outside Clouston, we also work in Stenness (1 mile north-east), Cairston (2 miles west), Grimeston (2 miles north), Germiston (3 miles east) and Wasbister (3 miles north-west). Where a site is remote or on an island, we plan travel and materials carefully, so the full address helps from the start.

What the job involves on each surface
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance, including keys, permits and any isolations.
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.
