About our fire stopping in Clanfield
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. Most enquiries involve snag lists that include open service penetrations and service penetrations left open after M&E works, on small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Clanfield it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places like Clanfield, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Compartment walls and floors in Clanfield
At about 55 miles from central London, Clanfield is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Tenant changes at parks like Enterprise Industrial Estate (to the south of Clanfield) bring new data and services, and openings through fire-resisting walls need the specified seal. Schools such as Clanfield Junior School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Landmarks near Clanfield
Recent enquiries here include premises near Rising Sun Inn and Horndean Technology College and the streets around them. Clanfield’s nearest station is Rowlands Castle station, about 4.2 miles south-east of the centre.

What happens if it’s left?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. For buildings around smaller places like Clanfield, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Cost factors for service penetrations
We price every job individually. The things that drive the figure:
- Whether old sealant has to be cut out first
- Site requirements such as inductions and permits
- The size and state of each joint
- Access and working height
Pricing service penetrations depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Clear photos of the problem areas
- Approximate linear metres or a joint schedule
- Your programme or deadline
- Whether the building will be occupied during the work

What else we do in Clanfield
What the job involves on each surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter, so we check before sealing.
Questions we are asked in Clanfield
Is Clanfield too small for you to travel to?
Not at all. Clanfield is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Can you take on a job at a hospital such as Petersfield Community Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months on every job.
Is sealant suitable for all service openings?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed, specified by your designer.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Do you approve fire stopping for building control?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed and agree any further records when we quote.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Do you need fire stopping in Clanfield?
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.
Look out for the following:
- Seals that don’t match their tested detail
- Openings found when ceilings come down for a refit
- Penetration schedules that need working through
- Builders’ foam or ordinary silicone in compartment walls
For a hospital such as Petersfield Community Hospital (5.1 miles north-east of Clanfield), penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Is the sealant right for the movement and the substrate?
- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area
