Why deal with it now?
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 other benefits follow. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Fire stopping in Kensal Town, done properly
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. If you have fire-stopping items raised at inspection or handover and improvised or mixed-product fire seals, we can help, on small duct penetrations where the tested detail allows, cable penetrations and linear gaps at wall heads alike. A single leaking joint is often how a building in Kensal Town 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.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in Kensal Town can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- 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.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Tell us which areas need to stay in use
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Questions we’re asked in Kensal Town
How does the move away from BS 476 affect penetration seals in Kensal Town?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it
How long does a typical visit take?
That varies with the scale of the job, though a typical visit usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Do you offer coloured sealant?
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.
Do you work in Kensal Town?
Yes. Kensal Town is in our area. For a quote, call 01277 525 020 or send details through our quote form.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Cost factors for service penetrations
Before we quote, we look at:
- Travel to remote or island sites
- Whether the work must be split into stages
- Access and working height
- How much there is to seal
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- Any specification or named product
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, ring 01277 525 020 or use the quote form.
Do you need fire stopping in Kensal Town?
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
It’s worth sending us details if you spot any of the following:
- Snag lists that include open service penetrations
- Service penetrations left open after M&E works
- Openings found when ceilings come down for a refit
- Open linear gaps along the top of fire-resisting walls
Workshops and IT rooms at colleges like Morley College London (to the south-east of Kensal Town) are re-serviced often, leaving penetrations to seal.
Questions to ask before you book
- Their pre-qualification and accreditations
- Their plan for phasing and protecting the area
- The named product and why it was chosen
- Do they follow the manufacturer’s priming guidance?

Penetration seals near Kensal Town
In England, Approved Document B covers fire stopping of openings and penetrations. 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. A 2-mile radius around Kensal Town takes in plenty of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
For an estates team at a campus like Imperial College London, 0.9 miles to the south-west of Kensal Town, summer M&E works are normally followed by a round of penetration sealing. For a unit at a centre such as Kensington Arcade, which lies south-east of Kensal Town, penetration seals are worth checking after each shop fit.

The nearest railway station is Queens Park (London) station, about 0.7 miles north of the centre. Well-known places in the area include Westfield London (1.2 miles south-west) and Paddington General Hospital (0.5 miles east). For a walk, there’s Campden Hill and Greville Place nature reserve.
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Walls or floors that aren’t fire-resisting to begin with
- Issuing fire ratings or certificates for seals
- Reviewing a building’s overall fire safety
If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think before you book.
