How we handle fire stopping in Cobham
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail. We work on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the usual reasons a site gets in touch are unsealed joints where partitions meet the slab and non-fire-rated filler around services. One point of contact handles commercial sealant work in Cobham from the first photos to the final walk-round, for single jobs and planned programmes alike.
Rural conversions around Cobham can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Where services cross fire walls in Cobham
Fire stopping of openings and penetrations in England falls under 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. Cobham lies roughly 23 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
At a college such as North Kent College Gravesend Campus, which lies north of Cobham, checking penetration seals after summer M&E works is good practice. Where a unit on an estate such as Bowes Industrial Centre (3 miles south-west of Cobham), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Cobham is about 3 miles south of Gravesend, in Kent. Our applicators travel to Cobham for work on service penetrations, handled exactly as we handle every other area. We work across 931 places in Kent. There’s a separate page for London, roughly 23 miles from Cobham.

Nearby towns on our patch include Maidstone (10 miles south-east), Sittingbourne (15 miles east), Dartford (8 miles north-west), Sevenoaks (12 miles south-west), Gravesend (3 miles north) and Tonbridge (14 miles south).

Common problems we fix in Cobham
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 the usual culprits.
Clients normally get in touch after noticing one or more of the following:
- Unsealed joints where partitions meet the slab
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed openings around new pipes and cables
- Damaged fire seals in risers and voids
On a hospital site such as Gravesham Community Hospital, 3.9 miles to the north-west of Cobham, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Cobham may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Tell us your opening times and when work is allowed
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we will need

What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Issuing fire ratings or certificates for seals
- Large openings beyond what any sealant detail covers
- Fire doors, dampers or other fire safety equipment
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.
What we seal
- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
What affects the price in Cobham
Your fixed quote is built from the real scope. It allows for:
- Any access equipment needed
- Site requirements such as inductions and permits
- Whether the work must be split into stages
- Travel to remote or island sites
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- How the joints are reached, and at what height
- Approximate linear metres or a joint schedule
- Whether an asbestos survey exists
- The type of building and who uses it
To get a fixed quote, phone 01277 525 020 or email the details over with the site address and an outline of the work. You can also send details through our quote form.

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
How the job changes by surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
Your questions answered
Does your area include sites such as Bowes Industrial Centre, near Cobham?
Yes, sites like Bowes Industrial Centre are within our area, along with the rest of Cobham. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is Cobham off your patch?
No. Places such as Cobham are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Will fire-rated sealant work on every penetration?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we flag those rather than improvise.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details for a fixed quote. Work can run area by area behind the M&E trades so areas aren’t left open.
Is fire stopping in Scotland covered by different guidance?
Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months on every job.
