For managing agents and facilities managers
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Fire stopping for commercial buildings in Clanville
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Clanville. If you are dealing with open linear gaps along the top of fire-resisting walls and expanding foam used as fire stopping, we can help. For commercial sealant work in Clanville, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Barn and farm-building conversions near places like Clanville often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why it’s worth doing now in Clanville
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. Halls, stores and units around places like Clanville may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Compartment walls and floors in Clanville
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Clanville is about 65 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Hospital estates such as Andover War Memorial Hospital (to the south-east of Clanville) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. In a school such as Appleshaw St Peter's CofE Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Do you need fire stopping in Clanville?
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
Site and facilities staff are often the first to spot these:
- Snag lists that include open service penetrations
- Service penetrations left open after M&E works
- Openings found when ceilings come down for a refit
- Open linear gaps along the top of fire-resisting walls
Offices at parks like Weyhill Business Park (to the south-west of Clanville) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
Before you book anyone
- Which product they’ll use, and why it suits the joint
- Their plan for phasing and protecting the area
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether old or failed sealant will be cut out, not overlaid
Surface by surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.
Clanville: questions and answers
Is Clanville too far out for you?
No. Places such as Clanville are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Weyhill Business Park, near Clanville?
Yes. Our area takes in Clanville and its surroundings, with estates and business parks such as Weyhill Business Park included. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Do you have third-party installer accreditation for fire stopping?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we’ll say so right away rather than waste your time.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Keeping the joints sound
A few simple habits keep the new joints working:
- Keep product data and details in the fire safety file
- Put resealing into every M&E and fit-out package
- Leave fire sealant to cure fully before covering it
- Keep general-purpose fillers away from compartment walls
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small.
Our process
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Clanville may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We ask for the product and detail your designer has specified.
- 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.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Let us know about inductions and permits
- Point out any areas we must not close
- Send any specification or drawings in advance
