Fire stopping in Comp
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. Those on your schedule are closed with the specified product. Most enquiries involve fire seals cut back for extra cables and never reinstated and fire stopping installed outside its tested range, across linear gaps at wall heads, cable penetrations and service gaps in risers. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Comp it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Comp, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email the details over and we’ll arrange a return visit.

How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Any access equipment needed
- Working within restricted access windows
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Your programme or deadline
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- Any specification or named product
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call 01277 525 020 or send photos by email.
After the work
For the best life from the joints:
- Put resealing into every M&E and fit-out package
- Keep general-purpose fillers away from compartment walls
- File the specified details where the next contractor can find them
- Get seals inspected before ceilings and boxing close
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
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.
Penetration seals near Comp
For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Central London is about 24 miles from Comp. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.
Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a school such as Platt Church of England Voluntary Aided Primary School, penetration sealing fits best at the end of the summer works. On a site such as Bourne Enterprise Centre, which lies north-west of Comp, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
Comp is about 3 miles west of Kings Hill, in Kent. Our applicators travel to Comp for work on service penetrations. Our Kent coverage takes in 931 places, large and small. London is covered too, around 24 miles from Comp.

What else we do in Comp
How the job changes by surface
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.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.
FAQs: Comp
Is Comp too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Do you cover business parks and estates near Comp, such as Bourne Enterprise Centre?
Yes. Estates, retail parks and business parks around Comp, Bourne Enterprise Centre among them, are all within reach. Photos and a short description are enough for a first look.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you have third-party installer accreditation for fire stopping?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Deciding what a wall or floor needs, which belongs to the designer
- Large openings beyond what any sealant detail covers
- Gaps in walls that were never built as compartment walls
If in doubt, call 01277 525 020 or email the details over and we will say what we think before you book.
Where we work in Comp
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
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.
How a job runs
