Fire stopping in The Frenches, done properly
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. What we bring is careful installation of the specified sealant, to the maker’s guidance in The Frenches and nearby. Most enquiries involve seals that don’t match their tested detail and unsealed openings around new pipes and cables, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations. Looking for mastic applicators who cover The Frenches? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Smaller places such as The Frenches still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we’re called out for in The Frenches
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
These are often picked up first by site or facilities staff:
- Snag lists that include open service penetrations
- Non-fire-rated filler around services
- Unsealed joints where partitions meet the slab
- Fire-rated sealant that has cracked or shrunk back
Wherever services are added at a hospital such as Romsey Community Hospital, 3.4 miles to the east of The Frenches, the compartment line has to be made good with the specified product.

What the job involves on each surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, with no gaps along the run.
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Questions about The Frenches
What happens to BS 476 references for fire stopping in The Frenches?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Would you work within a site like Romsey Community Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Penetration seals near The Frenches
In England, Approved Document B covers fire stopping of openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail.
Older community buildings such as Church of All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification. On a site such as Gardeners Business Park (1.7 miles south-west of The Frenches), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Halls, stores and units around places like The Frenches may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
