Commercial buildings in Barnes Cray
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as Christ Church, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Slade Green station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How we handle fire rated sealant in Barnes Cray
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you have standard silicone or caulk in a fire-stopping gap and damaged fire sealant left by other trades, we can help.
Community buildings, schools and small businesses around places like Barnes Cray have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Fire risk assessments, which need a qualified assessor
- Doors that are not fire doors in the first place
- A wall that isn’t a fire-resisting element to begin with
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

What the job involves on each surface
Flats and HMOs
Conversions normally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
The process
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. A visit to Barnes Cray is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Can you tell me how many minutes the seal will last?
We don’t give ratings or certificates for our work. Your specification sets the requirement, and we fit a product whose tested details meet it with a record of each location.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Is intumescent sealant the same as fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
Do you need fire rated sealant in Barnes Cray?
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.
Common reasons people contact us include:
- Gaps around pipes and cables through fire-resisting walls
- Seals cut through by electricians, plumbers or data installers
- Fire seals that have cracked with movement
- Joints picked up in a fire-stopping survey
Schools such as Haberdashers' Aske's Crayford Academy are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
What to look for in a quote
- How much experience the applicator has
- What product goes in the joint
- The length of the guarantee
- Are they insured?
Looking after it afterwards
So the new joints stay in good condition:
- Don’t paint over fire sealant until it has cured
- Photograph sealed gaps before they’re covered up
- Get damaged fire seals looked at promptly
- Include fire stopping when you schedule refits
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we’ll tell you which one you have.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
Why act early in Barnes Cray
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Homes in smaller places like Barnes Cray can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
