Fire stopping in Charlton
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. Site teams most often ask us about unsealed penetrations discovered above suspended ceilings and fire stopping installed outside its tested range, across pipe penetrations, service gaps in risers and cable penetrations. Whoever orders the work in Charlton, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A job near Charlton is normally planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our workmanship is guaranteed for 12 months, in Charlton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What affects the price in Charlton
The price varies from site to site. Expect it to depend on:
- Travel to remote or island sites
- The total length or number of joints
- The size and state of each joint
- Induction, permit and paperwork requirements
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
However big the job, the same details help:
- When you need the work done
- The postcode of the building
- Clear photographs of the problem areas
- What the building is and how it’s used
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Include service cupboards in routine inspections
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Ask the designer to confirm details early on refits
- Keep general-purpose fillers away from compartment walls
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
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.

Service penetrations in Charlton buildings
In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Charlton lies roughly 49 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
Large healthcare estates like Chichester Centre (4.6 miles south of Charlton) change their services often, so penetration seals are worth checking after M&E work. Older community buildings such as The Parish Church of the Blessed Virgin Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Charlton is about 5 miles north of Chichester, in West Sussex. Any commercial site in Charlton is covered, for single jobs and planned programmes alike. We work across 373 places in West Sussex. Sites around Portsmouth have their own page, about 16 miles away.
Work on service penetrations is covered throughout PO18. For a building on Charlton Road and Knight's Hill or nearby, send details and we’ll quote for service penetrations. Close to Charlton, our area also takes in Singleton (1 mile west), East Dean (1 mile east), West Dean (2 miles west), Cocking (3 miles north) and Heyshott (3 miles north). A short drive away, we cover Bognor Regis (9 miles south), Chichester (5 miles south), Selsey (12 miles south), Littlehampton (11 miles south-east), Rustington (12 miles south-east) and Storrington (13 miles east).

FAQs: Charlton
What happens to BS 476 references for fire stopping in Charlton?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you work around term dates at a campus such as University of Chichester?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you cover Charlton?
Yes. Charlton is in our area and the rest of West Sussex, within our coverage of Greater London, South East England and Scotland. To discuss a job, speak to us on 01277 525 020 or email us.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Can the building stay open while you work?
Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Signs you need fire stopping in Charlton
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
Look out for the following:
- Old intumescent sealant that has split away
- Fire seals cut back for extra cables and never reinstated
- Service penetrations left open after M&E works
- Improvised or mixed-product fire seals
Hotels such as Woodstock House Hotel (less than half a mile north of Charlton) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
Before you book anyone
- The terms of the workmanship guarantee
- What level of public liability insurance do they hold?
- How joint depth will be controlled
- Is the sealant right for the movement and the substrate?
Leave it or put it right?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. Around Charlton, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
