Fire stopping for commercial buildings in Arkley
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations, and the usual reasons a site gets in touch are penetration schedules that need working through and non-fire-rated filler around services. A single leaking joint is often how a building in Arkley first comes to us: we look at the rest while we are there and tell you what we find.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email us and we’ll come back to it.

Common questions from Arkley clients
Does your area include sites such as Elstree Trade Park, near Arkley?
Yes, sites like Elstree Trade Park are within our area, along with the rest of Arkley. Send details of the unit and the work through our quote form for a quick quote.
Can you work in a care home near Arkley with residents in?
Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.
How much does the work cost?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Which standards are fire seals tested to?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2. That rating only holds when the product is installed to its tested detail.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Service penetrations in Arkley buildings
There are five care or nursing homes within about 2 miles of Arkley. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. Several hotels sit less than 2 miles from Arkley. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Halls and meeting rooms at places like St Peter's Church sometimes gain new services, and any compartment wall crossed needs the specified seal. Campus buildings at universities such as Middlesex University, 3.6 miles south of Arkley, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.
Arkley is about 2 miles west of Barnet, in Greater London. We cover commercial sites throughout Arkley, for single jobs and planned programmes alike. 764 places across Greater London fall within our area, Arkley among them. Sites around London have their own page, about 12 miles away.

Surface by surface
Linear joints
Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
When to call us in Arkley
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
Any of the following is a good reason to get the joints checked over:
- Openings left by services added after handover
- Improvised or mixed-product fire seals
- Hidden openings found during inspections
- Damaged fire seals in risers and voids
Tenant changes at centres like Spires Shopping Centre, 1.3 miles to the north-east of Arkley, often mean new services through walls between units.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- Do they follow the manufacturer’s priming guidance?
- Will CSCS-carded applicators be on site?
- How they’ll work around occupants
After the work
Once the work is signed off, a little attention goes a long way:
- Flag new cables with no seal around them
- Arrange inspection before areas are covered up
- Put resealing into every M&E and fit-out package
- Look above ceilings when tiles are lifted for other jobs
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

How a job runs
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. All of Greater London is in the ULEZ, and kerbside space in Arkley can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- 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.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Warn occupants and staff about the work
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
Getting a fixed quote
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or email drawings and photos if you’d rather talk the job through.
Advice
Building owners, agents and FMs in Arkley
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Why deal with it now?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. 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. Putting it right early is less disruptive than dealing with the consequences.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
