Fire stopping for commercial buildings in High Barnet
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. We work on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are builders’ foam or ordinary silicone in compartment walls and penetration schedules that need working through. A specialist sealant contractor works differently from a general builder: in High Barnet, that means joint design, primers and backing rod as standard.
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.
A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Fire stopping around High Barnet: how the place shapes the job
Five care or nursing homes sit less than 2 miles from High Barnet. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
On estates like Hadley Manor Trading Estate (0.5 miles east of High Barnet), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. For a site team at a college like Oak Hill College, 2.8 miles south-east of High Barnet, fire-rated sealing is best scheduled after the summer works.

What affects the price in High Barnet
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- The size and state of each joint
- How accessible the joints are
- Phasing around occupants
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
The more we know, the firmer the quote. When you get in touch, include:
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- The type of building and who uses it
- The site address and postcode
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email a schedule or drawings.
When to bring in a specialist
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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Our process
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Confirm the product named in the specification
- Tell us what induction or permit system the site runs
- Point out parking and an unloading spot
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

When to call us in High Barnet
Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
It’s worth sending us details if you spot any of the following:
- Non-fire-rated filler around services
- Head-of-wall gaps with no fire seal
- Fire-rated sealant that has cracked or shrunk back
- Unsealed penetrations discovered above suspended ceilings
Theatres, wards and plant rooms at sites like Barnet Hospital (0.5 miles south-west of High Barnet) all have compartment walls crossed by services.
What your quote should include
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- Their plan for phasing and protecting the area
- How long is the guarantee, and what does it include?

Questions we’re asked in High Barnet
Is a hospital such as Barnet Hospital somewhere you can work?
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.
Will you work in a care home in High Barnet without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
How long before the joints can be used?
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.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you design or specify fire stopping?
No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Do you hold third-party fire-stopping installer certification?
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.
Looking after the joints
Once the work is signed off, these steps help:
- Check with the data sheet before painting over fire sealant
- Agree the fire-stopping specification before services go in
- Brief every trade that openings they make must be sealed
- Arrange inspection before areas are covered up
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
