Questions we’re asked in South Wonston
What does the BS 476 change mean for fire-rated sealant in South Wonston?
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.
Does your area include sites such as Beeches Industrial Park, near South Wonston?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

Fire stopping in South Wonston, done properly
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on linear gaps at wall heads, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are seals disturbed by maintenance and left open and unsealed joints where partitions meet the slab. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in South Wonston is the same: the right product in a properly prepared joint.
For a smaller site near South Wonston, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we will come back to it.

For managing agents and facilities managers
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Different surfaces, different methods
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness first.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.
Fire stopping in South Wonston: the local picture
Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 59 miles from South Wonston. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
For an estates team at a campus like University of Winchester, 4.1 miles to the south of South Wonston, summer M&E works are typically followed by a round of penetration sealing. Theatres, wards and plant rooms at sites like Royal Hampshire County Hospital (4 miles south of South Wonston) all have compartment walls crossed by services.
South Wonston is about 4 miles north of Winchester, in Hampshire. Our applicators travel to South Wonston for work on service penetrations, handled exactly as we handle every other area. Our Hampshire coverage takes in 723 places, large and small. Our Southampton page has more on work in that area.

When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Walls or floors that aren’t fire-resisting to begin with
- Signing off or certifying a building’s fire stopping
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
Surfaces we seal
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Pipe penetrations
- Cable penetrations
- Joints between fire-resisting walls and floors
What we’re called out for in South Wonston
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Most enquiries start with something like this:
- Hidden openings found during inspections
- Seals that don’t match their tested detail
- Damaged fire seals in risers and voids
- Service penetrations left open after M&E works
In a building such as St Margaret's, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- Is the sealant right for the movement and the substrate?
- Their approach to joint depth and backing
What happens if it’s left?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these, and the other benefits follow. Older rural buildings around South Wonston move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
