Fire stopping in Kennington
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Cost factors for service penetrations
To price the job, we consider:
- The site’s rules and procedures
- Any access equipment needed
- Location, for remote and island sites
- Which sealant the job calls for
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- The asbestos register, for older buildings
- The product your specification calls for
- Access details, including height
- What the building is and how it’s used
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email a schedule or drawings.
Fire stopping in Kennington, done properly
Facilities managers in Kennington often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you are dealing with builders’ foam or ordinary silicone in compartment walls and fire stopping installed outside its tested range, we can put it right, whatever the surface. A single leaking joint is often how a building in Kennington first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Buildings in a smaller place such as Kennington that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Kennington: questions and answers
Will you plan work around the academic year at somewhere like Ashford College?
Yes. Education sites typically 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 will confirm them alongside the quote.
Is hospital work, at somewhere like The One Ashford Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
Will you sign off the seals for us?
No. Approval sits with the designer, principal designer or building control. We will confirm the products and details used and agree any further records when we quote.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Which standards are fire seals tested to?
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.
Fire stopping in Kennington: the local picture
At about 48 miles from central London, Kennington is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Large healthcare estates like The One Ashford Hospital, 2 miles to the south-east of Kennington, change their services often, so penetration seals are worth checking after M&E work. For a hotel such as The Conningbrook Hotel, 0.5 miles to the east of Kennington, penetration seals are worth checking after any refit or services upgrade. For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing.
Kennington is about 2 miles north-east of Ashford, in Kent. Looking for fire stopping in Kennington? We can help. Kennington is one of 931 places in Kent on our list for service penetrations. London is covered too, some 48 miles away.

What else we do in Kennington
Surface by surface
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we will tell you what the detail says instead.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.
Honest limits
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Large openings beyond what any sealant detail covers
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Joints and surfaces we work on
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For a site in Kennington, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
Getting the site ready
- Let us know about inductions and permits
- Point out any areas we must not close
- Share the asbestos register for older buildings
Ask for a quote
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email drawings and photos with what you know.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Brief every trade that openings they make must be sealed
- Leave fire sealant to cure fully before covering it
- Treat an open penetration as a priority repair
- Arrange inspection before areas are covered up
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open instead of being left for someone else.
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. In a smaller place such as Kennington, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
