Fire stopping for Gunnista sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping for commercial buildings in Gunnista
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. If you have builders’ foam or ordinary silicone in compartment walls and fire-stopping items raised at inspection or handover, we can help. Whoever orders the work in Gunnista, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Travel to smaller places like Gunnista 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, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Issuing fire ratings or certificates for seals
- Fire risk assessments, a job for a competent assessor
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think.
What we seal
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
Fire-rated sealing for Gunnista buildings
Gunnista has several hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. 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. We install fire-rated sealant to that tested detail where it is specified.
Hospital estates such as Montfield Hospital (2.2 miles south-west of Gunnista) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. In a school such as Anderson High School, fire-rated sealant goes in around service penetrations where it is specified.

Questions we’re asked in Gunnista
Do you work on the island where Gunnista is?
Yes. Islands are part of our area, Gunnista included. We group island work where we can and plan around the crossings.
Can you work at a site such as North Ness Business Park, by Gunnista?
Yes. Estates, retail parks and business parks around Gunnista, North Ness Business Park among them, are all within reach. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Is the work guaranteed?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What does an EI 60 rating mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Signs you need fire stopping in Gunnista
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Typical triggers for a call:
- Expanding foam used as fire stopping
- Open linear gaps along the top of fire-resisting walls
- Improvised or mixed-product fire seals
- Fire seals cut back for extra cables and never reinstated
Older community buildings such as St Ola's Church and burial-ground that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

What affects the price in Gunnista
There’s no standard rate for sealant work, because every site is different. What we look at:
- Any access equipment needed
- Location, for remote and island sites
- The product specified
- Induction, permit and paperwork requirements
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 and we’ll explain how it’s made up.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Send us:
- The type of building and who uses it
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Different surfaces, different methods
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Gunnista, we aim for one trip, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Flag any permit to work we will need
- Share the asbestos register for older buildings
- Send your site hours and access windows
