Compartment walls and floors in Mersham
For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail. Mersham lies roughly 52 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
In a building such as Church of St John the Baptist, any service penetration through a fire-resisting wall should be sealed to the specified detail. Holiday works at schools like Mersham Primary School often leave service openings to seal before pupils return.
Mersham is about 3 miles south-east of Ashford, in Kent. Commercial clients in Mersham can call on us for service penetrations. Mersham is one of 931 places we cover in Kent for service penetrations. For work in that direction, see our Brighton page.

How we handle fire stopping in Mersham
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about improvised or mixed-product fire seals and hidden openings found during inspections, on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations. Looking for mastic applicators who cover Mersham? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Smaller places such as Mersham 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. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why deal with it now?
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. Halls, stores and units around places like Mersham may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Why us?
- Old sealant cut out, never sealed over
- CSCS-carded applicators
- Fixed quotes based on photos, drawings or a visit
- Fully insured, including public liability cover

Common problems we fix in Mersham
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 a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Site and facilities staff are often the first to spot these:
- Hidden openings found during inspections
- Fire-rated sealant that has cracked or shrunk back
- Head-of-wall gaps with no fire seal
- Improvised or mixed-product fire seals
Theatres, wards and plant rooms at sites like William Harvey Hospital (Ashford), 1.6 miles north of Mersham, all have compartment walls crossed by services.

Common questions from Mersham clients
Is a smaller place like Mersham outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Do you take on work at healthcare sites like William Harvey Hospital (Ashford)?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Do you hold third-party fire-stopping installer certification?
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. If your contract requires third-party installer certification, we’re not the right fit for that package.
How long does a job like this take?
It depends on the scope, but the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we’ll set out a timescale with the quote.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Different surfaces, different methods
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Rural sites near Mersham may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Share your working hours and any access restrictions
- Let us know about inductions and permits
- Agree which areas must stay open

General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
