How we handle fire stopping in Stone Street
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. We work on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the failures we’re asked to look at most are openings found when ceilings come down for a refit and damaged fire seals in risers and voids. Most enquiries from Stone Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Rural conversions around Stone Street can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Do you need fire stopping in Stone Street?
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Things that usually lead to an enquiry:
- Open linear gaps along the top of fire-resisting walls
- Expanding foam used as fire stopping
- Unsealed penetrations discovered above suspended ceilings
- Unsealed openings around new pipes and cables
Holiday works at schools like St Lawrence Church of England Primary School often leave service openings to seal before pupils return.

What else we do in Stone Street
Fire stopping in Stone Street: the local picture
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 Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Stone Street is about 22 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
On a site such as Chaucer Business Park (1.9 miles north of Stone Street), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Halls and meeting rooms at places like St Lawrence sometimes gain new services, and any compartment wall crossed needs the specified seal.

Site staff or a sealant specialist?
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
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, which is what makes a joint last.
Questions about Stone Street
Is Stone Street off your patch?
No. Places such as Stone Street are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Stone Street?
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.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
What sets the cost
Quotes vary with the job. It mainly depends on:
- Backing rod, priming and other preparation
- Which sealant the job calls for
- Working within restricted access windows
- The total length or number of joints
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.
What we need to price the job
However big the job, these details speed things up:
- The postcode of the building
- Clear photos of the problem areas
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or send details through our quote form to discuss it first.
Different surfaces, different methods
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We follow your schedule area by area.
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.
Leave it or put it right?
The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. For buildings around smaller places like Stone Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, 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, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

How a job runs
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Stone Street are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- 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.
Getting the site ready
- Tell us your opening times and when work is allowed
- Point out parking and an unloading spot
- Move anything stored against the joints
