Fire stopping in Hundred Acres
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Hundred Acres. We work on service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the usual reasons a site gets in touch are expanding foam used as fire stopping and hidden openings found during inspections. A single leaking joint is often how a building in Hundred Acres first comes to us: we look at the rest while we’re there and tell you what we find.
Smaller places such as Hundred Acres still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What affects the price in Hundred Acres
To price the job, we consider:
- How accessible the joints are
- Which sealant the job calls for
- The size and state of each joint
- 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. Tell us how the joints are reached and call for a quote.
Sending details for a quote
Whether it’s one area or a whole building, these details speed things up:
- How the joints are reached, and at what height
- The site address and postcode
- The asbestos register, for older buildings
- Any specification or named product
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
When to call us in Hundred Acres
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. The tested detail for a linear joint states the width and movement it covers.
Clients typically get in touch after noticing one or more of the following:
- Fire sealant pulled out of the opening
- Snag lists that include open service penetrations
- Seals that don’t match their tested detail
- Hidden openings found during inspections
For a hotel such as The Old House Hotel, 1.3 miles west of Hundred Acres, penetration seals are worth checking after any refit or services upgrade.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What site paperwork they can supply
- What level of public liability insurance do they hold?
- Can the work be phased to keep areas open?

For England, the fire stopping of penetrations is dealt with in Approved Document B. 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.

Your questions answered
Would you work within a site like Knowle Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work at a site such as Knowle Village Business Park, by Hundred Acres?
Yes. Estates, retail parks and business parks around Hundred Acres, Knowle Village Business Park among them, are all within reach. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
After the work
After handover, a little attention goes a long way:
- Ask which product is in place before decorating
- Have penetrations checked while they can still be seen
- Brief every trade that openings they make must be sealed
- Include service cupboards in routine inspections
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
