About our fire stopping in Bix
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are fire-rated sealant that has cracked or shrunk back and head-of-wall gaps with no fire seal. Whoever orders the work in Bix, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
A job near Bix is typically planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Service penetrations in Bix buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail. At about 37 miles from central London, Bix is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Halls and meeting rooms at places like Church of St James sometimes gain new services, and any compartment wall crossed needs the specified seal. Theatres, wards and plant rooms at sites like Townlands Memorial Hospital, 2.3 miles south-east of Bix, all have compartment walls crossed by services.
Bix is about 6 miles north of Caversham, in Oxfordshire. Our applicators travel to Bix for work on service penetrations. Our Oxfordshire coverage takes in 423 places, from busy centres to rural villages. For work in that direction, see our Reading page, about 8 miles away.

We also cover Middle Assendon (1 mile north-east), Lower Assendon (1 mile south-east), Fawley Bottom (1 mile north-east), Catslip (2 miles north-west) and Shepherd's Green (2 miles south-west). Bigger towns within reach include Didcot (13 miles west), Thame (13 miles north), Henley-on-Thames (3 miles south-east), Benson (8 miles north-west), Chinnor (10 miles north) and Wallingford (8 miles west).

Questions about Bix
What does the BS 476 change mean for fire-rated sealant in Bix?
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.
Is Bix off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
- Signing off or certifying a building’s fire stopping
If in doubt, ring 01277 525 020 or email the details over and we will say what we think.
Joints and surfaces we work on
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Cable penetrations
Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down. Halls, stores and units around places like Bix 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.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Put resealing into every M&E and fit-out package
- Have penetrations checked while they can still be seen
- Check risers and ceiling voids after each round of works
- Ask the designer to confirm details early on refits
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.

Surface by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones usually call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Quoting for work in Bix
Before we quote, we look at:
- Backing rod, priming and other preparation
- Working within restricted access windows
- Travel to remote or island sites
- The product specified
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- What the building is and how it’s used
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Bix may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Send any specification or drawings in advance
- Flag any permit to work we’ll need
- Arrange parking or a loading space
