How we handle fire stopping in Sidlesham Common
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. Most enquiries involve unsealed joints where partitions meet the slab and builders’ foam or ordinary silicone in compartment walls, on pipe penetrations, small duct penetrations where the tested detail allows and service gaps in risers. Most enquiries from Sidlesham Common 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.
Smaller places such as Sidlesham Common 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.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sets the cost
A fixed quote reflects the actual work. It allows for:
- Location, for remote and island sites
- The product specified
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- When you need the work done
- The site address and postcode
- Whether the building will be occupied during the work
- The product your specification calls for
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Don’t let anyone top up a fire seal with the wrong product
- Check risers and ceiling voids after each round of works
- Brief every trade that openings they make must be sealed
- Agree the fire-stopping specification before services go in
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Leave it or put it right?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. 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 Sidlesham Common may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Service penetrations in Sidlesham Common buildings
Sidlesham Common is about 57 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Offices at parks like Enborne Business Park (to the south of Sidlesham Common) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. At a university such as University of Chichester, which lies north of Sidlesham Common, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Hotels like Crouchers Hotel (1.2 miles north of Sidlesham Common) are refurbished in phases, and each phase can open up compartment walls.

Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building around Sidlesham Common, tell us how to find it and who will meet us. 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.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Tell us what induction or permit system the site runs
- Share your working hours and any access restrictions
- Arrange parking or a loading space

What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Is the BS 476 change in 2029 relevant to fire stopping?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, subject to the Government’s transitional arrangements. After that, the European classification under BS EN 13501-2 is the route. Your designer will choose products with the right evidence.
Do the same rules apply to fire stopping in Scotland?
Scotland sets its own building regulations, with Technical Handbooks. Either way, we install the specified sealant to its tested detail.
