Fire stopping in Barnsbury, done properly
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers, and the failures we are asked to look at most are head-of-wall gaps with no fire seal and fire-stopping items raised at inspection or handover. For commercial sealant work in Barnsbury, you deal with one contact from quote to sign-off, whether it’s one building or several.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Do you need fire stopping in Barnsbury?
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.
If one of these sounds familiar, it’s time for a closer look:
- Unsealed penetrations discovered above suspended ceilings
- Builders’ foam or ordinary silicone in compartment walls
- Penetration schedules that need working through
- Improvised or mixed-product fire seals
For a unit at a centre such as Brunswick Centre, 1.4 miles to the south of Barnsbury, penetration seals are worth checking after each shop fit.

Common questions from Barnsbury clients
Does your area include sites such as Roman Way Industrial Estate, near Barnsbury?
Yes. Estates, retail parks and business parks around Barnsbury, Roman Way Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Can you work on a hospital site such as St. Pancras Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can the sealant be colour-matched?
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.
What changes on 2 September 2029?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance.
Do you work in Scotland as well as England?
Our area runs from Greater London and the South East to every part of Scotland. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a job in Barnsbury, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Getting the site ready

Why act early in Barnsbury
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Why appoint us
- Work to your specification and the manufacturer’s guidance
- Over 20 years of commercial sealing
- Health and safety: CHAS accredited
- Constructionline member

Quoting for work in Barnsbury
To price the job, we consider:
- The site’s rules and procedures
- Travel to remote or island sites
- How accessible the joints are
- Which sealant the job calls for
A quote for service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- What the building is and how it’s used
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- The asbestos register, for older buildings
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Settle who seals which penetrations at the start of a project
- Flag new cables with no seal around them
- Include service cupboards in routine inspections
- Brief every trade that openings they make must be sealed
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Fire-rated sealing for Barnsbury buildings
A good number of hotels sit less than 2 miles from Barnsbury. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. The 2 miles around Barnsbury include three care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.
At a university such as University of the Arts London, 0.6 miles south-west of Barnsbury, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a unit at a site such as Roman Way Industrial Estate, less than half a mile to the south-east of Barnsbury, new power or data runs between office and warehouse can breach a compartment wall.
