How the job changes by surface
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Fire stopping for commercial buildings in Belmont
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Belmont. Site teams most often ask us about non-fire-rated filler around services and penetration schedules that need working through, on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations. One point of contact handles commercial sealant work in Belmont from the first photos to the final walk-round, whether it’s one building or several.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why deal with it now?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is usually a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Getting scaffold, permits or access booked in Belmont takes effort, so it makes sense to deal with every failing joint while access is in place.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What else we do in Belmont
Maintenance after handover
To get the most from the new sealant:
- Record which product was used where
- Ask which product is in place before decorating
- Foam or ordinary sealant is never a fire-seal repair
- Make fire stopping part of every scope that crosses a fire-resisting wall
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Where services cross fire walls in Belmont
There are a number of hotels within about 2 miles of Belmont. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. The 2 miles around Belmont include three care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
For a unit at a site such as Kimpton Industrial Park (2.4 miles north of Belmont), new power or data runs between office and warehouse can breach a compartment wall. For a site team at a college like Sutton College of Learning for Adults, 1.3 miles north of Belmont, fire-rated sealing is best scheduled after the summer works.
Belmont is about 2 miles south of Sutton, in Greater London. We cover Belmont and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Belmont is one of 764 places we cover in Greater London for service penetrations. Sites around London have their own page, about 12 miles away.
Postcode districts covered here: SM2 and SM5 for service penetrations. If your site is on The Avenue, Sandy Lane and Downs Road or close by, we can quote for service penetrations. Just outside Belmont, we also work in Cheam (1 mile north-west), Cuddington (2 miles north-west), North Looe (2 miles west), Nork (2 miles south-west) and North Cheam (2 miles north). Further afield, our area takes in London (12 miles north-east), City of Westminster (12 miles north), Marylebone (12 miles north), Kensington (11 miles north), St Pancras (13 miles north) and Shoreditch (14 miles north-east).
Around Belmont
Around Belmont, our work takes us to commercial buildings near Howell Hill, Harris Academy Sutton and Glaisdale School and the streets around them. There’s a railway station in Belmont itself: Belmont station. A little further out are The Ashley Centre (3 miles west) and Chessington Castle Hill (4 miles west). Not far away are Belmont Pastures and Duppas Hill.
Site staff or a sealant specialist?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Signs you need fire stopping in Belmont
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.
Clients usually get in touch after noticing one or more of the following:
- Seals that don’t match their tested detail
- Expanding foam used as fire stopping
- Openings found when ceilings come down for a refit
- Fire seals cut back for extra cables and never reinstated
For a hospital such as Royal Marsden Hospital, 0.5 miles east of Belmont, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
Questions to ask before you book

Belmont: questions and answers
Can you work around term dates at a campus such as University for the Creative Arts - Epsom?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on jobs in Belmont where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Will fire-rated sealant work on every penetration?
No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution.
What will the job cost?
We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.
Do the same rules apply to fire stopping in Scotland?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, using products tested for their end use.
What do BS EN 1366-3 and BS EN 13501-2 mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. That rating only holds when the product is installed to its tested detail.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- For older buildings, check the asbestos register before work
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
