Fire stopping in Charing Hill
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on cable penetrations, pipe penetrations and service gaps in risers, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and seals that don’t match their tested detail. A specialist sealant contractor works differently from a general builder: in Charing Hill, that means joint design, primers and backing rod as standard.
Barn and farm-building conversions near places like Charing Hill often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Keeping the joints sound
A few simple habits keep the new joints working:
- Settle who seals which penetrations at the start of a project
- Check with the data sheet before painting over fire sealant
- Put resealing into every M&E and fit-out package
- Don’t let anyone top up a fire seal with the wrong product
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

Why it’s worth doing now in Charing Hill
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Older rural buildings around Charing Hill move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Your questions answered
Is a smaller place like Charing Hill outside your area?
Not at all. Charing Hill is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
What does the BS 476 change mean for fire-rated sealant in Charing Hill?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Signs you need fire stopping in Charing Hill
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Things that normally lead to an enquiry:
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed openings around new pipes and cables
- Fire-rated sealant that has cracked or shrunk back
- Seals disturbed by maintenance and left open
Older community buildings such as Church of St Peter and St Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Before you book anyone
- Their plan for phasing and protecting the area
- What site paperwork they can supply
- Will failed sealant be removed rather than covered?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?

Cost factors for service penetrations
These are the things that shape the price:
- Site requirements such as inductions and permits
- Working within restricted access windows
- Quantities, in metres or numbers
- Location, for remote and island sites
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What we need to price the job
We can often quote from photos and a few details. Please tell us:
- Drawings or a marked-up plan, if available
- The product your specification calls for
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
- Signing off or certifying a building’s fire stopping
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
