Fire stopping in Crossbush, done properly
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. 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. If you’re dealing with damaged fire seals in risers and voids and fire sealant pulled out of the opening, we can put it right. A specialist sealant contractor works differently from a general builder: on jobs in Crossbush, preparation and product choice get the time they need.
Around smaller places like Crossbush, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Work we carry out in West Sussex comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we’ll come back to it.

Compartment walls and floors in Crossbush
Crossbush lies roughly 49 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. A number of hotels sit less than 2 miles from Crossbush. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
At a healthcare site like Arundel & District Community Hospital (1.5 miles north-west of Crossbush), new services through compartment walls are a constant, and each needs the specified seal. Industrial units on estates such as The Vinery Industrial Estate, 1.3 miles east of Crossbush, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Common questions from Crossbush clients
What does the BS 476 change mean for fire-rated sealant in Crossbush?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you take on a job at a hospital such as Arundel & District Community Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email us. Include photos or drawings if you have them.
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, because fresh silicone will not bond with aged silicone.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use.

Leave it or put it right?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Older rural buildings around Crossbush move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

What we are called out for in Crossbush
Openings in fire-resisting walls typically appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Look out for the following:
- Snag lists that include open service penetrations
- Head-of-wall gaps with no fire seal
- Damaged fire seals in risers and voids
- Fire stopping installed outside its tested range
Halls and meeting rooms at places like The Parish Church of St Mary Magdalen sometimes gain new services, and any compartment wall crossed needs the specified seal.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it
- What site paperwork they can supply
- Their pre-qualification and accreditations
- The named product and why it was chosen
What sets the cost
Quotes vary with the job. It mainly depends on:
- Phasing around occupants
- Backing rod, priming and other preparation
- The total length or number of joints
- Removal of failed or old sealant
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- Whether the building will be occupied during the work
- The product your specification calls for
- Anything awkward about access or site hours
- The postcode of the building
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or email drawings and photos to discuss it first.
When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Reviewing a building’s overall fire safety
- Gaps in walls that were never built as compartment walls
- Signing off or certifying a building’s fire stopping
If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer.
Joints and surfaces we work on
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Crossbush can be grouped with others nearby. You will have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- 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.
Getting the site ready
- Send any specification or drawings in advance
- Tell staff and tenants when we’ll be in
- For older buildings, check the asbestos register before work
Quotes
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email the details over.

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Include service cupboards in routine inspections
- Leave fire sealant to cure fully before covering it
- Flag new cables with no seal around them
- Foam or ordinary sealant is never a fire-seal repair
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
