How we handle fire stopping in Croydon
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, speak to us on 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve service penetrations left open after M&E works and builders’ foam or ordinary silicone in compartment walls, on small duct penetrations where the tested detail allows, service gaps in risers and joints between fire-resisting walls and floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Croydon is the same: the right product in a properly prepared joint.
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.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email us and we will come back to it.

FAQs: Croydon
Do you work on fire-rated sealing in hotels in Croydon?
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 Croydon?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months.
General trades versus a specialist
Certain joints really need a specialist: for example 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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Building owners, agents and FMs in Croydon
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Croydon can form part of a wider programme.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Different surfaces, different methods
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe. We follow whatever the detail requires and flag anything we can’t match.
Small ducts
Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.
Fire-rated sealing for Croydon buildings
Croydon has four care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. A 2-mile radius around Croydon takes in plenty of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
For a unit at a site such as Pilton Industrial Estate, which lies north-west of Croydon, new power or data runs between office and warehouse can breach a compartment wall. Hotels such as Kirkdale Hotel, under half a mile to the south of Croydon, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
Croydon is about 9 miles south of London, in Greater London. Anywhere in CR0, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places, large and small. London is covered too, some 9 miles away.
Business premises anywhere in CR0, CR2, CR9 and CR8 are within our area for service penetrations. For a building on High Street, Church Road and Ruskin Square or nearby, send details and we will quote for service penetrations. Main routes into Croydon include the A235 and B243, useful when we plan access and materials. Sites close to Croydon are covered too, including South Croydon (1 mile south), Coombe (1 mile east), Addiscombe (2 miles north-east), Ashburton (2 miles north-east) and Woodside (2 miles north-east). Further afield, our area takes in London (9 miles north), City of Westminster (10 miles north), Marylebone (11 miles north), Kensington (10 miles north-west), St Pancras (11 miles north) and Shoreditch (11 miles north).
Around Croydon
Around Croydon, our work takes us to commercial buildings near Cambridge Tutors College, Rutherford School and Keg & Grill pub, among other places. Croydon has its own railway station: South Croydon station. Nearby you will also find Croydon Airport Visitor Centre (1.2 miles south-west) and Croydon University Hospital (1.7 miles north). For a walk, there’s Roundshaw Downs and Duppas Hill.
When to call us in Croydon
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
Look out for the following:
- Snag lists that include open service penetrations
- Fire-rated sealant that has cracked or shrunk back
- Unsealed penetrations discovered above suspended ceilings
- Damaged fire seals in risers and voids
On a hospital site such as Croydon University Hospital (1.7 miles north of Croydon), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
