Fire stopping in Barnes
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. If you are dealing with fire seals cut back for extra cables and never reinstated and fire sealant pulled out of the opening, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Barnes, that means joint design, primers and backing rod as standard.
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 will hear it from us.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Different surfaces, different methods
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.
Owners, agents and contractors
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Barnes can sit alongside others in a wider programme.
FAQs: Barnes
Do you take on jobs in Barnes where loading and access are tightly controlled?
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. We allow for the ULEZ, which covers every borough
Can you work on a hospital site such as Barnes Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you have third-party installer accreditation for fire stopping?
No. We don’t hold a third-party fire-stopping installer certificate. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we’re not the right fit for that package.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
Do the same rules apply to fire stopping in Scotland?
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.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What affects the price in Barnes
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Distance, for remote addresses
- The total length or number of joints
- How accessible the joints are
- Which sealant the job calls for
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 fixed quote once you have the details.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Foam or ordinary sealant is never a fire-seal repair
- Brief every trade that openings they make must be sealed
- Agree the fire-stopping specification before services go in
- Report damaged or disturbed seals as soon as they’re spotted
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.
Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Fire stopping around Barnes: what changes locally
There are plenty of hotels within about 2 miles of Barnes. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Workshops and IT rooms at colleges like South Thames College Wandsworth Campus (to the south-east of Barnes) are re-serviced often, leaving penetrations to seal. Campus buildings at universities such as University of Roehampton, 1.2 miles to the south of Barnes, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Theatres, wards and plant rooms at sites like Barnes Hospital (to the south-west of Barnes) all have compartment walls crossed by services.
Barnes is about 2 miles west of Fulham, in Greater London. Commercial clients in Barnes can call on us for service penetrations, as part of our coverage of Greater London. Our Greater London coverage takes in 764 places, large and small. For work in that direction, see our London page.

Also close by are Polish Library POSK in London (1.4 miles north) and The Harrodian School (0.6 miles north). There’s a railway station in Barnes itself: Barnes Bridge station.

On site: what to expect
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. All of Greater London is in the ULEZ, and kerbside space in Barnes 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.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Flag any permit to work we will need
- Explain the parking and delivery arrangements
- Tell us which areas need to stay in use
