Fire stopping across Knock
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Cost factors for service penetrations
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- The site’s rules and procedures
- Working within restricted access windows
- Location, for remote and island sites
- Whether old sealant has to be cut out first
A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Drawings or a marked-up plan, if available
- The type of building and who uses it
- Any dates the work must fit around
- A wide shot and a close-up of the area
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
How we handle fire stopping in Knock
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you are dealing with snag lists that include open service penetrations and non-fire-rated filler around services, we can put it right, whatever the surface. A single leaking joint is often how a building in Knock first comes to us: we look at the rest while we are there and tell you what we find.
In smaller Scottish places like Knock, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.
Work we carry out in Na h-Eileanan Siar comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or send details through our quote form and we will arrange a return visit.

Where services cross fire walls in Knock
Island jobs, Knock among them, are planned around the ferry and the forecast. With the specification and photographs 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.
On estates like Parkend Industrial Estate, 3 miles west of Knock, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
Knock (Gaelic: An Cnoc) is in Na h-Eileanan Siar. Businesses, contractors and managing agents in Knock can call on us for service penetrations, as part of our coverage of Na h-Eileanan Siar. 87 places across Na h-Eileanan Siar fall within our area, including Knock.
Anyone looking for fire stopping in HS2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Seaview and A' Chnuic. You’ll find Knock on or near the A866, so getting applicators and materials to site is simple. Just outside Knock, we also work in Na h-Eileanan an Iar (1 mile west), Aiginis (1 mile west), Lower Bayble (1 mile east), Garrabost (2 miles north-east) and Pabail Uarach (2 miles east). Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you speak to us on 01277 525 020 or email the details over.

For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
We work for building owners and managing agents on everything from one building to a spread of sites around Knock. Several sites can go on one quote, which keeps the paperwork simple.
When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- Gaps in walls that were never built as compartment walls
- Fire risk assessments, a job for a competent assessor
- Writing the fire-stopping specification
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Joints and surfaces we work on
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Linear gaps at wall heads
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Travel to smaller Scottish places like Knock is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.
- 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.
Getting the site ready
- Arrange parking or a loading space
- Tell staff and tenants when we will be in
- Move anything stored against the joints

Common problems we fix in Knock
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.
It’s worth sending us details if you spot any of the following:
- Snag lists that include open service penetrations
- Unsealed openings around new pipes and cables
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed joints where partitions meet the slab
Large healthcare estates like Western Isles Hospital, 4.5 miles to the west of Knock, change their services often, so penetration seals are worth checking after M&E work.

Knock: questions and answers
Is hospital work, at somewhere like Western Isles Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you take on a job in Knock, on the island?
Yes. Our area covers all of Scotland, cities, towns and islands alike, and that includes island locations such as Knock. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
How do we ask for a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
