Fire stopping for commercial buildings in Kentish Town
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you have expanding foam used as fire stopping and head-of-wall gaps with no fire seal, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Kentish Town is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Aftercare for building managers
After handover, a little attention goes a long way:
- Don’t let anyone top up a fire seal with the wrong product
- Look above ceilings when tiles are lifted for other jobs
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Check with the data sheet before painting over fire sealant
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
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.

Fire-rated sealing for Kentish Town buildings
With tenants changing and fit-outs following, London buildings see service routes altered again and again. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. The 2 miles around Kentish Town include three care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.
Offices at parks like Regis Road Business Park (less than half a mile north of Kentish Town) 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, 1.1 miles to the south-east of Kentish Town, 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 O2 Centre (to the west of Kentish Town) often mean new services through walls between units.
Kentish Town is about 2 miles east of Hampstead, in Greater London. Across the NW5 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Greater London, 764 places are covered, Kentish Town among them.
We take on service penetrations across the NW5, NW1 and NW3 postcode area. For a building on Eton Road, Oval Road and Regal Lane or nearby, we can quote for service penetrations. Nearby places we also cover include Chalk Farm (1 mile west), Camden Town (1 mile south-east), Gospel Oak (1 mile north), Primrose Hill (1 mile south-west) and Agar Town (1 mile south-east). Bigger towns within reach include London (4 miles south-east), Kensington (4 miles south-west), Shoreditch (3 miles south-east), Walthamstow (6 miles north-east), Hoxton (3 miles east) and Whitechapel (4 miles south-east).

How the quote is worked out
We price every job individually. The things that drive the figure:
- How much there is to seal
- How accessible the joints are
- Phasing around occupants
- The size and state of each joint
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- The site address and postcode
To get a fixed quote, give us a call on 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. You can also send details through our quote form.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Deciding what a wall or floor needs, which belongs to the designer
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire risk assessments, a job for a competent assessor
If in doubt, phone 01277 525 020 or email us and we’ll say what we think.
Where we work in Kentish Town
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
Surface by surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail.
Questions about Kentish Town
Can work at a site such as University of the Arts London fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Is BS 476 being phased out?
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.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
What do BS EN 1366-3 and BS EN 13501-2 mean?
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.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
From enquiry to sign-off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We read the specification, drawings or penetration schedule you send.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Move anything stored against the joints
- Warn occupants and staff about the work
- Arrange parking or a loading space

Advice
What happens if it’s left?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.
