Fire stopping in North Lochs, done properly
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, speak to us on 01277 525 020 or use the quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. If you have seals disturbed by maintenance and left open and head-of-wall gaps with no fire seal, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in North Lochs, that means joint design, primers and backing rod as standard.
For a building near North Lochs, we plan fire-rated sealing so it’s finished in one visit where possible. Send the specification and photographs of the openings, with sizes if you have them.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

FAQs: North Lochs
How do the Scottish rules apply to fire-rated sealing in North Lochs?
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. Design sits with the designer and the verifier; installation to the tested detail is our part.
Will you travel to North Lochs on the island?
Yes. Islands are part of our area, North Lochs included. We group island work where we can and plan around the crossings.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Keeping the joints sound
After handover, a little attention goes a long way:
- Check with the data sheet before painting over fire sealant
- Record which product was used where
- Get seals inspected before ceilings and boxing close
- Ask the designer to confirm details early on refits
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
What else we do in North Lochs
Common problems we fix in North Lochs
Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access typically bring them to light.
Typical triggers for a call:
- Open linear gaps along the top of fire-resisting walls
- Seals that don’t match their tested detail
- Fire-rated sealant that has cracked or shrunk back
- Seals disturbed by maintenance and left open
Wherever services are added at a hospital such as Western Isles Hospital, 6 miles to the north-east of North Lochs, the compartment line has to be made good with the specified product.
Comparing quotes
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- Health and safety accreditation such as CHAS
- Do they follow the manufacturer’s priming guidance?
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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. Getting these wrong usually costs more in the end than doing them right.
Service penetrations in North Lochs buildings
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. Where fire-rated sealant is specified, that’s what we install, to the tested detail. Work on North Lochs has to fit the ferry timetable and the forecast. With the specification and photographs of the openings, the right fire-rated products travel with us.
In a building such as Parish Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.
North Lochs is about 6 miles south-west of Stornoway, in Na h-Eileanan Siar. We send applicators to North Lochs for service penetrations, handled exactly as we handle every other area. 87 places across Na h-Eileanan Siar fall within our area, North Lochs among them.

What the job involves on each surface
Metal pipes
Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs near North Lochs are often grouped with others in the same area.
