Fire stopping in St Katherines, done properly
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. Most enquiries involve snag lists that include open service penetrations and unsealed openings around new pipes and cables, on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in St Katherines, preparation and product choice get the time they need.
Around smaller places such as St Katherines, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

General trades versus a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Ask the designer to confirm details early on refits
- Keep product data and details in the fire safety file
- Keep general-purpose fillers away from compartment walls
- Treat an open penetration as a priority repair
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original, or a new specification from the designer.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.
How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
Common problems we fix in St Katherines
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position.
It’s worth sending us details if you spot any of the following:
- Unsealed joints where partitions meet the slab
- Improvised or mixed-product fire seals
- Fire seals cut back for extra cables and never reinstated
- Unsealed penetrations discovered above suspended ceilings
For buildings in and around St Katherines, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.
What your quote should include
- How the joint faces will be prepared and primed
- Their approach to joint depth and backing
- Can the work be phased to keep areas open?
- Are they CHAS accredited or on Constructionline?
Penetration seals near St Katherines
Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, and products should be tested for their end use. We install what’s specified, to the product’s tested detail.
For a hospital such as House Of Daviot Hospital, 4.4 miles to the south-west of St Katherines, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

Your questions answered
What do Scotland’s building standards say about service penetrations in St Katherines?
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. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
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, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around St Katherines, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Warn occupants and staff about the work
- Tell us which areas need to stay in use
- Confirm the product named in the specification

Advice
Why it’s worth doing now in St Katherines
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. Around smaller places like St Katherines, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
