Fire stopping in East Wickham
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping in East Wickham
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. If you are dealing with snag lists that include open service penetrations and improvised or mixed-product fire seals, we can help. Looking for mastic applicators who cover East Wickham? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
In a London area such as East Wickham, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in East Wickham can sit alongside others in a wider programme.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Surface by surface
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.
Signs you need fire stopping in East Wickham
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.
Typical triggers for a call:
- Openings found when ceilings come down for a refit
- Fire sealant pulled out of the opening
- Service penetrations left open after M&E works
- Snag lists that include open service penetrations
Colleges such as Shooters Hill Sixth Form College (to the west of East Wickham) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will RAMS and insurance details be available?
- Who will actually carry out the work
- The terms of the workmanship guarantee
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Record which product was used where
- Report damaged or disturbed seals as soon as they’re spotted
- Brief every trade that openings they make must be sealed
- Ask the designer to confirm details early on refits
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.
What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Construction that lacks the fire resistance the seal relies on
- Signing off or certifying a building’s fire stopping
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think before you book.

- Cable penetrations

- Service gaps in risers
- Joints between fire-resisting walls and floors
Our process
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
- Agree which areas must stay open

Service penetrations in East Wickham buildings
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.
Tenant changes at parks like Gateway Business Centre (to the north of East Wickham) bring new data and services, and openings through fire-resisting walls need the specified seal. On a hospital site such as Memorial Hospital (1.4 miles west of East Wickham), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Questions about East Wickham
Is a hospital such as Memorial Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
How do we ask for a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.
What do BS EN 1366-3 and BS EN 13501-2 mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. EI 60 means integrity and insulation for 60 minutes in the tested arrangement; installing to the detail is what carries that across to site.
How long does a typical visit take?
It depends on the scope, but the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Do you certify or sign off fire stopping?
No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the product and detail installed.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
