Aftercare for building managers
Regular inspection catches problems early. In particular:
- Don’t let anyone top up a fire seal with the wrong product
- Treat an open penetration as a priority repair
- File the specified details where the next contractor can find them
- Arrange inspection before areas are covered up
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.
Fire stopping in Canning Town
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and service gaps in risers, and the usual reasons a site gets in touch are old intumescent sealant that has split away and damaged fire seals in risers and voids. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Canning Town is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Why deal with it now?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
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.

Common questions from Canning Town clients
Could you schedule work at a campus like University of East London for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them.
Is the BS 476 change in 2029 relevant to fire stopping?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, subject to the Government’s transitional arrangements. After that, the European classification under BS EN 13501-2 is the route. Your designer will choose products with the right evidence.
Are you members of a third-party fire-stopping installer scheme?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Can you reseal penetrations after our M&E works?
Yes. Send the schedule or marked-up drawings and the specified product details and a fixed quote follows. We can follow the services contractor floor by floor keeping pace with the programme.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
What the job involves on each surface
Small ducts
We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically.
What we’re called out for in Canning Town
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
If one of these sounds familiar, it’s time for a closer look:
- Fire stopping installed outside its tested range
- Head-of-wall gaps with no fire seal
- Snag lists that include open service penetrations
- Fire sealant pulled out of the opening
At a college such as Newham College London, 1.1 miles north of Canning Town, checking penetration seals after summer M&E works is good practice.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The terms of the workmanship guarantee

Advice
Fire stopping in Canning Town: the local picture
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. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.
Offices at parks like Mint Business Park (to the north-west of Canning Town) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Wherever services are added at a hospital such as Newham University Hospital, 0.6 miles to the north-east of Canning Town, the compartment line has to be made good with the specified product.
