About our fire stopping in Shirburn
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Site teams most often ask us about non-fire-rated filler around services and damaged fire seals in risers and voids, across pipe penetrations, cable penetrations and joints between fire-resisting walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, in Shirburn it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Shirburn, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When to call us in Shirburn
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it.
Site and facilities staff are often the first to spot these:
- Openings found when ceilings come down for a refit
- Damaged fire seals in risers and voids
- Builders’ foam or ordinary silicone in compartment walls
- Seals that don’t match their tested detail
Hotels like Fox And Hounds Hotel And Public House, 0.9 miles south-west of Shirburn, are refurbished in phases, and each phase can open up compartment walls.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- What level of public liability insurance do they hold?
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Construction that lacks the fire resistance the seal relies on
- Fire risk assessments, a job for a competent assessor
- Signing off or certifying a building’s fire stopping
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly.
Surfaces we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
Surface by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter and we work within those limits.
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.
Where services cross fire walls in Shirburn
In England, Approved Document B covers fire stopping of 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. Central London is about 40 miles from Shirburn. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
On estates like Watlington Industrial Estate, 1.2 miles to the south-west of Shirburn, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. In a building such as All Saints Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Shirburn is about 6 miles south of Thame, in Oxfordshire. Shirburn sits inside our coverage and the rest of Oxfordshire, with the same fixed quotes and 12-month guarantee as everywhere else. Across Oxfordshire, 423 places are covered, Shirburn among them. Sites around Oxford have their own page, about 12 miles away.
We cover the OX49 postcode districts for service penetrations. Among the streets we cover are Watlington Road, Castle Road and Blenheim Road, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Lewknor (1 mile north-east), South Weston (2 miles north), Christmas Common (2 miles south-east), Postcombe (2 miles north) and Howe Hill (3 miles south) for service penetrations. Further afield, our area takes in Oxford (12 miles north-west), Didcot (11 miles west), Abingdon-on-Thames (13 miles west), Thame (6 miles north), Henley-on-Thames (9 miles south-east) and Benson (5 miles south-west).

Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Jobs in and around smaller places like Shirburn are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- 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.
Preparing the site
- Point out parking and an unloading spot
- Tell staff and tenants when we will be in
- Flag any permit to work we’ll need

Shirburn: questions and answers
Is Shirburn too small for you to travel to?
Not at all. Shirburn is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Shirburn?
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.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
After the work
Keep the joints in good shape with a few simple steps:
- Agree the fire-stopping specification before services go in
- Report damaged or disturbed seals as soon as they’re spotted
- Check with the data sheet before painting over fire sealant
- Foam or ordinary sealant is never a fire-seal repair
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
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, not months later.
