Fire stopping for Crofton sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Different surfaces, different methods
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.
Fire stopping for commercial buildings in Crofton
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve openings found when ceilings come down for a refit and unsealed openings around new pipes and cables, on cable penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows. Facilities teams, main contractors and managing agents in Crofton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
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.

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 we finish with a walk round so the work can be signed off. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Make sure the joints can be reached
- Let us know about inductions and permits
- Point out any areas we must not close

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Issuing fire ratings or certificates for seals
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
If you are not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer before you book.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Pipe penetrations
- Cable penetrations
Do you need fire stopping in Crofton?
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, which then have to be put right.
What tends to prompt an enquiry:
- Openings found when ceilings come down for a refit
- Fire-rated sealant that has cracked or shrunk back
- Service penetrations left open after M&E works
- Penetration schedules that need working through
For a site team at a college like Bromley College (2.1 miles west of Crofton), fire-rated sealing is best scheduled after the summer works.
Before you book anyone
- Will RAMS and insurance details be available?
- Do they follow the manufacturer’s priming guidance?
- Who will actually carry out the work
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Fire-rated sealing for Crofton buildings
There are five care or nursing homes within about 2 miles of Crofton. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits.
For an estates team at a campus like University of Greenwich Avery Hill Campus, 4.9 miles north of Crofton, summer M&E works are normally followed by a round of penetration sealing. At a healthcare site like Orpington Hospital, 1.1 miles south-east of Crofton, new services through compartment walls are a constant, and each needs the specified seal.
Crofton is about 1 mile south-west of Orpington, in Greater London. Across the BR6 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Crofton is one of 764 places we cover in Greater London for service penetrations. Our London page has more on work in that area.
Commercial sites across BR6 and BR5 are covered. Among the streets we cover are Grange Road, Reed Avenue and Gumping Road. Nearby places we also cover include Broom Hill (1 mile north-east), Locksbottom (1 mile west), Petts Wood (1 mile north), Farnborough (1 mile south) and Green Street Green (2 miles south) for service penetrations. Nearby towns on our patch include London (11 miles north-west), City of Westminster (14 miles north-west), Marylebone (14 miles north-west), Kensington (15 miles north-west), St Pancras (14 miles north-west) and Shoreditch (12 miles north-west).

For managing agents and facilities managers
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Crofton can form part of a wider programme across Greater London.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Your questions answered
Do you work on fire-rated sealing in hotels in Crofton?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
What happens to BS 476 references for fire stopping in Crofton?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
How do I request a quote?
