Fire stopping for commercial buildings in Kennington
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Kennington and nearby. We work on joints between fire-resisting walls and floors, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are seals disturbed by maintenance and left open and builders’ foam or ordinary silicone in compartment walls. Most enquiries from Kennington start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

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, with backing added if the detail requires it.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.
Kennington: questions and answers
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. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Kennington?
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.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Include service cupboards in routine inspections
- Record which product was used where
- Arrange inspection before areas are covered up
- Ask which product is in place before decorating
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We read the specification, drawings or penetration schedule you send.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Flag any permit to work we’ll need
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance

What sets the cost
The price varies from site to site. Expect it to depend on:
- How much existing material needs removing
- How accessible the joints are
- Quantities, in metres or numbers
- Distance, for remote addresses
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Clear photographs of the problem areas
- Where the site is, with the postcode
- Your programme or deadline
- Any specification or named product
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email a schedule or drawings.
Why act early in Kennington
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Getting scaffold, permits or access booked in Kennington takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Fire stopping in Kennington: the local picture
There are two care or nursing homes within about 2 miles of Kennington. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. We seal to the specification and the product’s tested detail, working within the building’s permits.
Offices at parks like Handel Business Centre (under half a mile north-west of Kennington) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Campus buildings at universities such as University of the Arts London (to the west of Kennington) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Tenant changes at centres like Southernwood Retail Park (2 miles east of Kennington) often mean new services through walls between units.
Kennington is about 2 miles south-west of London, in Greater London. We send applicators to Kennington for service penetrations. Across Greater London, 764 places are covered, including Kennington.
