About our fire stopping in Kensington
Facilities managers in Kensington often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. If you have openings left by services added after handover and expanding foam used as fire stopping, we can put it right, on joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows alike. A specialist sealant contractor works differently from a general builder: in Kensington, that means joint design, primers and backing rod as standard.
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.
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.

On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in Kensington can be scarce. Let us know about any on-site parking or loading arrangements when you send the job 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.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Share your working hours and any access restrictions
- Make sure the joints can be reached
- Agree which areas must stay open

General trades versus a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
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.
Signs you need fire stopping in Kensington
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.
Common reasons buildings call us in:
- Open linear gaps along the top of fire-resisting walls
- Snag lists that include open service penetrations
- Old intumescent sealant that has split away
- Non-fire-rated filler around services
For an estates team at a campus like University of Westminster, less than half a mile to the south-west of Kensington, summer M&E works are typically followed by a round of penetration sealing.
What your quote should include
- The named product and why it was chosen
- How they handle RAMS and site documents
- Can the work be phased to keep areas open?
- Do they follow the manufacturer’s priming guidance?

Questions we’re asked in Kensington
Can you seal around new services in a hotel near Kensington?
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.
Can you work around term dates at a campus such as University of Westminster?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Approving the work on behalf of building control
- Large openings beyond what any sealant detail covers
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly before you book.
Surfaces we seal
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Arrange inspection before areas are covered up
- Check with the data sheet before painting over fire sealant
- File the specified details where the next contractor can find them
- Foam or ordinary sealant is never a fire-seal repair
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Where services cross fire walls in Kensington
In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Plenty of hotels sit less than 2 miles from Kensington. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.
For a hospital such as Cromwell Hospital (0.6 miles south-east of Kensington), penetration sealing is typically phased ward by ward, with infection-control rules agreed first. For a building at a site such as Berghem Mews Business Village, 0.7 miles to the west of Kensington, a check of penetration seals after each fit-out is good practice.

How the job changes by surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
