How we handle fire stopping in South Ruislip
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. Site teams most often ask us about expanding foam used as fire stopping and fire stopping installed outside its tested range, on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads. A single leaking joint is often how a building in South Ruislip first comes to us: we look at the rest while we’re there and tell you what we find.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Your questions answered
Can work at a site such as Westminster University fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you work on a hospital site such as Cygnet Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Are you members of a third-party fire-stopping installer scheme?
No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Is fire stopping in Scotland covered by different guidance?
Scotland sets its own building regulations, with Technical Handbooks. Wherever the site is, our work follows the specification and the tested detail.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
What changes on 2 September 2029?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance, with clause 2.1.14 covering service penetrations.
Fire stopping around South Ruislip: points for this area
The area within 2 miles of South Ruislip holds several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
Workshops and IT rooms at colleges like Christ the Redeemer College (to the north-east of South Ruislip) are re-serviced often, leaving penetrations to seal. Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Record which product was used where
- Get seals inspected before ceilings and boxing close
- Check with the data sheet before painting over fire sealant
- Settle who seals which penetrations at the start of a project
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.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.
What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Plastic pipes whose detail calls for a collar or wrap
- Approving the work on behalf of building control
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Surfaces we seal
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Cable penetrations

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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area.

- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- For older buildings, check the asbestos register before work

Related advice
Do you need fire stopping in South Ruislip?
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 leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Typical triggers for a call:
- Fire sealant pulled out of the opening
- Openings found when ceilings come down for a refit
- Unsealed joints where partitions meet the slab
- Damaged fire seals in risers and voids
At a retail site such as Brook Retail Park, less than half a mile to the south-east of South Ruislip, walls between units may be fire-resisting, so services added in a refit need the specified seal.
