Fire stopping in Kent Street
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Owners, agents and contractors
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 will confirm them with the quote.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Fire stopping for commercial buildings in Kent Street
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. The enquiries we see most involve openings found when ceilings come down for a refit and improvised or mixed-product fire seals, on joints between fire-resisting walls and floors, linear gaps at wall heads and small duct penetrations where the tested detail allows. For commercial sealant work in Kent Street, you deal with one contact from quote to sign-off, whether it’s one building or several.
For a smaller site near Kent Street, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Questions about Kent Street
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Kent Street?
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.
Can you work at a site such as Oakendene Industrial Estate, by Kent Street?
Yes, sites like Oakendene Industrial Estate are within our area, along with the rest of Kent Street. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can staff carry on working while you are here?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Common problems we fix in Kent Street
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in and later need putting right.
Site and facilities staff are often the first to spot these:
- Penetration schedules that need working through
- Unsealed joints where partitions meet the slab
- Seals that don’t match their tested detail
- Openings found when ceilings come down for a refit
Industrial units on estates such as Oakendene Industrial Estate (to the north of Kent Street) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- The terms of the workmanship guarantee
- What site paperwork they can supply
- How joint depth will be controlled
Quoting for work in Kent Street
We price every job individually. The main factors are:
- Working within restricted access windows
- The total length or number of joints
- Removal of failed or old sealant
- The product specified
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- How the joints are reached, and at what height
- Any dates the work must fit around
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email us.
Compartment walls and floors in Kent Street
At about 37 miles from central London, Kent Street is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. 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. Either way, we install the specified product to its tested detail.
For a hospital such as The Dene Hospital (3.8 miles east of Kent Street), penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. Jobs in and around smaller places like Kent Street are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed
- Tell staff and tenants when we’ll be in
Get a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Large openings beyond what any sealant detail covers
- Signing off or certifying a building’s fire stopping
- Fire risk assessments, a job for a competent assessor
If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

What else we do in Kent Street
What the job involves on each surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any outside it are raised with you.
