Fire stopping for commercial buildings in The Chart
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or send details through our quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on pipe penetrations, cable penetrations and linear gaps at wall heads, and what we’re called in for most is seals that don’t match their tested detail and openings left by services added after handover. Looking for mastic applicators who cover The Chart? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Barn and farm-building conversions near places like The Chart often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Compartment walls and floors in The Chart
Approved Document B is the English guidance that covers fire stopping around 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 Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements.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 18 miles from The Chart. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
Wherever services are added at a hospital such as Tandridge Priory (to the north-west of The Chart) the compartment line has to be made good with the specified product. Schools such as Limpsfield CofE Infant School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
The Chart is about 6 miles south-east of Caterham, in Surrey. We cover The Chart and the rest of Surrey, with the same fixed quotes and 12-month guarantee as everywhere else. 379 places across Surrey fall within our area, including The Chart. For work in that direction, see our London page (18 miles or so).
Postcode districts covered here: RH8 for service penetrations. Buildings on Stoneleigh Road, St Andrews Way and Ridlands Lane are within our area. Just outside The Chart, we also work in Pains-Hill (1 mile west), Moorhouse Bank (1 mile north-east), Goodley Stock (1 mile east), Limpsfield (1 mile north-west) and Crockham Hill (1 mile south-east). Further afield, our area takes in Epsom (15 miles north-west), Horley (10 miles south-west), Redhill (9 miles west), Ewell (15 miles north-west), Reigate (10 miles west) and Caterham (6 miles north-west).

Aftercare for building managers
After handover, a little attention goes a long way:
- Keep product data and details in the fire safety file
- Report damaged or disturbed seals as soon as they’re spotted
- Brief every trade that openings they make must be sealed
- Include service cupboards in routine inspections
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.
Why it’s worth doing now in The Chart
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 and avoids a much larger catch-up later. Older rural buildings around The Chart 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.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

FAQs: The Chart
What does the BS 476 change mean for fire-rated sealant in The Chart?
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.
Can you work on a hospital site such as Tandridge Priory?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
How do you choose the sealant?
The specification comes first, if there is one. 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.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Travel to remote or island sites
- Site requirements such as inductions and permits
- Any access equipment needed
- Whether old sealant has to be cut out first
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote when you’re ready.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The postcode of the building
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Your programme or deadline
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email drawings and photos.
Owners, agents and contractors
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
When to call us in The Chart
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.
Clients typically get in touch after noticing something like this:
- Head-of-wall gaps with no fire seal
- Unsealed penetrations discovered above suspended ceilings
- Seals that don’t match their tested detail
- Old intumescent sealant that has split away
Older community buildings such as St Andrew's that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Comparing quotes
- Whether their applicators hold CSCS cards
- What site paperwork they can supply
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking anything from one day to a planned run of visits, depending on the number of seals and the access. If others near The Chart need work, visits can be combined. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Confirm the product named in the specification
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
