Fire stopping in Biggin Hill
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you are dealing with old intumescent sealant that has split away and seals disturbed by maintenance and left open, we can help. Facilities teams, main contractors and managing agents in Biggin Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Service penetrations in Biggin Hill buildings
In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
For a school such as Oaklands Primary Academy, penetration sealing fits best at the end of the summer works. Halls and meeting rooms at places like St Mark's Church sometimes gain new services, and any compartment wall crossed needs the specified seal.
Biggin Hill is about 6 miles east of Caterham, in Greater London. Anywhere in TN16, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Site staff or a sealant specialist?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
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.
Different surfaces, different methods
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones normally call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
What affects the price in Biggin Hill
We price every job individually. The things that drive the figure:
- Travel to remote or island sites
- The site’s rules and procedures
- Backing rod, priming and other preparation
- Any access equipment needed
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Sending details for a quote
However big the job, the same details help:
- How the joints are reached, and at what height
- The asbestos register, for older buildings
- When you need the work done
- What the building is and how it’s used
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Have penetrations checked while they can still be seen
- Report damaged or disturbed seals as soon as they’re spotted
- Keep product data and details in the fire safety file
- Don’t let anyone top up a fire seal with the wrong product
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
How a job runs
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. In Biggin Hill, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- 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.
Before we start on site
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Let us know about inductions and permits
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

What we are called out for in Biggin Hill
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.
What tends to prompt an enquiry:
- Fire seals cut back for extra cables and never reinstated
- Non-fire-rated filler around services
- Unsealed penetrations discovered above suspended ceilings
- Open linear gaps along the top of fire-resisting walls
In a hotel such as The Landing Hotel, which lies north of Biggin Hill, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Common questions from Biggin Hill clients
Is a hospital such as Warlingham Park Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you cover business parks and estates near Biggin Hill, such as Biggin Hill Airport Trading Estate?
Yes, sites like Biggin Hill Airport Trading Estate are within our area, along with the rest of Biggin Hill. Send details of the unit and the work through our quote form for a quick quote.
Do you certify or sign off fire stopping?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail.
Is sealant suitable for all service openings?
No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Is BS 476 being phased out?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance, with clause 2.1.14 covering service penetrations.
