Compartment walls and floors in Mundaydean Bottom
Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. Mundaydean Bottom lies roughly 31 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Tenant changes at parks like Globe Business Park, 2 miles to the south-east of Mundaydean Bottom, bring new data and services, and openings through fire-resisting walls need the specified seal. Residences at universities like Buckinghamshire New University (Wycombe Campus), 3.6 miles north-east of Mundaydean Bottom, have compartment walls that must be resealed whenever services change.

About our fire stopping in Mundaydean Bottom
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations, and what we are called in for most is damaged fire seals in risers and voids and seals that don’t match their tested detail. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Mundaydean Bottom, preparation and product choice get the time they need.
A job near Mundaydean Bottom is normally planned around one visit, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Advice
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. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Halls, stores and units around places like Mundaydean Bottom 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 can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What affects the price in Mundaydean Bottom
The price varies from site to site. It mainly depends on:
- Any access equipment needed
- Distance, for remote addresses
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Any specification or named product
- Access details, including height
- The site address and postcode
- Drawings or a marked-up plan, if available
For a fixed quote, phone 01277 525 020 or send details through our quote form. Our quote form is another easy route.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Walls or floors that aren’t fire-resisting to begin with
- Fire doors, dampers or other fire safety equipment
- Signing off or certifying a building’s fire stopping
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
What we seal
- Joints between fire-resisting walls and floors
- Cable penetrations
- Service gaps in risers
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
Common problems we fix in Mundaydean Bottom
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.
Any of the following is a good reason to get the joints checked over:
- Service penetrations left open after M&E works
- Seals that don’t match their tested detail
- Open linear gaps along the top of fire-resisting walls
- Non-fire-rated filler around services
Wherever services are added at a hospital such as Marlow Community Hospital (1.7 miles south-east of Mundaydean Bottom) the compartment line has to be made good with the specified product.

- Will RAMS and insurance details be available?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
How the job changes by surface
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Mundaydean Bottom: questions and answers
Is Mundaydean Bottom too small for you to travel to?
No. Places such as Mundaydean Bottom are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can work at a site such as Buckinghamshire New University (Wycombe Campus) fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What does an EI 60 rating mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.
Do you approve fire stopping for building control?
No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the product and detail installed and agree any further records when we quote.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
How do you deal with asbestos in old sealant?
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.
