About our fire stopping in Bonhill
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. We work on pipe penetrations, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are builders’ foam or ordinary silicone in compartment walls and seals that don’t match their tested detail. A specialist sealant contractor works differently from a general builder: on jobs in Bonhill, preparation and product choice get the time they need.
Hotels and care homes around smaller places like Bonhill often have services added during refurbishment. 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: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Travel to smaller Scottish places like Bonhill is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.

After the work
Once the work is signed off, these steps help:
- Keep general-purpose fillers away from compartment walls
- Report damaged or disturbed seals as soon as they’re spotted
- File the specified details where the next contractor can find them
- Get seals inspected before ceilings and boxing close
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way unless the designer specifies otherwise.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.
Why act early in Bonhill
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Bonhill, a repair visit takes planning, so it’s better to act early.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

FAQs: Bonhill
Is a hospital such as Vale of Leven District General Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you seal service penetrations in hotels around Bonhill?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
What about RAMS and site documents?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure.
How do I request a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
When to bring in a specialist
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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Signs you need fire stopping in Bonhill
Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
These are often picked up first by site or facilities staff:
- Openings left by services added after handover
- Head-of-wall gaps with no fire seal
- Hidden openings found during inspections
- Fire stopping installed outside its tested range
For a unit at a site such as Vale of Leven Industrial Estate (0.6 miles south of Bonhill), new power or data runs between office and warehouse can breach a compartment wall.

Service penetrations in Bonhill buildings
The area within 2 miles of Bonhill holds several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. 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 fire-rated sealant to that tested detail where it is specified.
Large healthcare estates like Vale of Leven District General Hospital, 1.4 miles north-west of Bonhill, change their services often, so penetration seals are worth checking after M&E work. Schools such as Vale of Leven Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
