Fire stopping across Larkfield
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How the job changes by surface
Metal pipes
Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.
Fire stopping for commercial buildings in Larkfield
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. The enquiries we see most involve snag lists that include open service penetrations and unsealed penetrations discovered above suspended ceilings, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and pipe penetrations. Most enquiries from Larkfield start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
A job near Larkfield is normally planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- File the specified details where the next contractor can find them
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Don’t let anyone top up a fire seal with the wrong product
- 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. If a seal has to be opened for a new service, it should be reinstated to the same detail.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Where services cross fire walls in Larkfield
There are two care or nursing homes within about 2 miles of Larkfield. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Larkfield is about 27 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.
Residences at universities like University for the Creative Arts - Maidstone, 3.3 miles south-east of Larkfield, have compartment walls that must be resealed whenever services change. Older community buildings such as Church of the Holy Trinity that have been rewired or given new heating can have service gaps through walls worth checking against the specification. In a hotel such as Hamlet Hotel Maidstone, which lies south-west of Larkfield, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
Larkfield is about 4 miles north-west of Maidstone, in Kent. We cover Larkfield and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Across Kent, 931 places are covered, Larkfield among them. For work in that direction, see our London page (27 miles or so).

How a job runs

Your questions answered
Can you seal around new services in a hotel near Larkfield?
Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.
Will you work in a care home in Larkfield without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months on every job.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Leave it or put it right?
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. Older rural buildings around Larkfield move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
