Fire stopping for Corpach sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Gaps in walls that were never built as compartment walls
- Large openings beyond what any sealant detail covers
- Fire doors, dampers or other fire safety equipment
If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
Surfaces we seal
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Service gaps in risers
How we handle fire stopping in Corpach
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. Most enquiries involve hidden openings found during inspections and fire-stopping items raised at inspection or handover, on small duct penetrations where the tested detail allows, cable penetrations and pipe penetrations. A single leaking joint is often how a building in Corpach first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Corpach, 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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What happens if it’s left?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Renewing every failing joint on one visit is the sensible approach for a place like Corpach. Send photographs and we will quote for everything together.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

When to call us in Corpach
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
Most enquiries start with something like this:
- Fire stopping installed outside its tested range
- Expanding foam used as fire stopping
- Fire-stopping items raised at inspection or handover
- Open linear gaps along the top of fire-resisting walls
In a school such as Lochaber High School, fire-rated sealant goes in around service penetrations where it is specified.
What your quote should include
- Which product they’ll use, and why it suits the joint
- How the existing material will be dealt with
- Whether their applicators hold CSCS cards
- Their plan for phasing and protecting the area
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Corpach, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Let building users know which areas are affected
- Send any specification or drawings in advance
- Arrange parking or a loading space

How the job changes by surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we will tell you what the detail says instead.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Get seals inspected before ceilings and boxing close
- Foam or ordinary sealant is never a fire-seal repair
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Include service cupboards in routine inspections
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small.
Fire-rated sealing for Corpach buildings
There are a number of hotels within about 2 miles of Corpach. 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, using products tested for the way they’re used. We install what’s specified, to the product’s tested detail.
Where a unit on an estate such as Blar Mhor Industrial Estate (1.7 miles east of Corpach), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. On a hospital site such as Belford Hospital, 2 miles south-east of Corpach, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
