How we handle fire stopping in Stock
Facilities managers in Stock often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about fire-rated sealant that has cracked or shrunk back and openings found when ceilings come down for a refit, on service gaps in risers, linear gaps at wall heads and small duct penetrations where the tested detail allows. Most enquiries from Stock start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Smaller places such as Stock 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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why it’s worth doing now in Stock
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Older rural buildings around Stock move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Questions about Stock
How does the move away from BS 476 affect penetration seals in Stock?
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.
Is hospital work, at somewhere like Mayflower Community Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you work in Stock?
Yes. Sites across Stock are covered.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you need fire stopping in Stock?
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Typical triggers for a call:
- Hidden openings found during inspections
- Fire seals cut back for extra cables and never reinstated
- Expanding foam used as fire stopping
- Fire sealant pulled out of the opening
Holiday works at schools like Stock Church of England Primary School often leave service openings to seal before pupils return.
What to look for in a quote
- Can the work be phased to keep areas open?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether primer will be used where the manufacturer specifies it
- Health and safety accreditation such as CHAS
For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Rural sites near Stock may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Tell us which areas need to stay in use
- Make sure the joints can be reached
Ask for a quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Fire-rated sealing for Stock buildings
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. Our part stays the same: the specified product, installed to its tested detail. Central London is about 26 miles from Stock. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
At a healthcare site like Mayflower Community Hospital, 3.4 miles south-west of Stock, new services through compartment walls are a constant, and each needs the specified seal. For a hotel such as Greenwoods Hotel Spa and Retreat (under half a mile north of Stock), penetration seals are worth checking after any refit or services upgrade.
Stock is about 3 miles north-east of Billericay, in Essex. Looking for fire stopping in Stock? We can help, as we do across Essex. Stock is one of 644 places in Essex on our list for service penetrations. Sites around London have their own page, about 26 miles away.

Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.
Doing it in-house
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.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
