Fire stopping around Dalserf: how the place shapes the job
In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, with products tested for that end use. We install what’s specified, to the product’s tested detail. Dalserf has a number of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Industrial units on estates such as Castlehill Industrial Estate (to the east of Dalserf) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Theatres, wards and plant rooms at sites like University Hospital Wishaw, 2.9 miles north of Dalserf, all have compartment walls crossed by services.
Dalserf is about 2 miles east of Larkhall, in South Lanarkshire.

Fire stopping for commercial buildings in Dalserf
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about service penetrations left open after M&E works and builders’ foam or ordinary silicone in compartment walls, on joints between fire-resisting walls and floors, linear gaps at wall heads and pipe penetrations. One point of contact handles commercial sealant work in Dalserf from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Refurbishments in small hotels, schools and care homes around places like Dalserf can leave gaps around new services. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.
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.

Different surfaces, different methods
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.

What we are called out for in Dalserf
Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
If one of these sounds familiar, it’s time for a closer look:
- Seals disturbed by maintenance and left open
- Seals that don’t match their tested detail
- Head-of-wall gaps with no fire seal
- Service penetrations left open after M&E works
Schools such as Larkhall Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
Before you book anyone
- Which product they’ll use, and why it suits the joint
- How long is the guarantee, and what does it include?
- Will CSCS-carded applicators be on site?
- What level of public liability insurance do they hold?
Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Put resealing into every M&E and fit-out package
- Include service cupboards in routine inspections
- Ask the designer to confirm details early on refits
- Flag new cables with no seal around them
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Plastic pipes whose detail calls for a collar or wrap
- Reviewing a building’s overall fire safety
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
What we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Dalserf: questions and answers
What do Scotland’s building standards say about service penetrations in Dalserf?
Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.
Do you take on work at healthcare sites like University Hospital Wishaw?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
