Fire stopping for commercial buildings in Milton-under-Wychwood
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. Most enquiries involve improvised or mixed-product fire seals and damaged fire seals in risers and voids, on small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors.

How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Milton-under-Wychwood, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- 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.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.

Different surfaces, different methods
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.
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Signing off or certifying a building’s fire stopping
- Fire risk assessments, a job for a competent assessor
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Cable penetrations
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
Fire stopping around Milton-under-Wychwood: what changes locally
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. Our part stays the same: the specified product, installed to its tested detail. A 2-mile radius around Milton-under-Wychwood takes in a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
In a hotel such as Shaven Crown Hotel (0.9 miles east of Milton-under-Wychwood), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. For a school such as Wychwood Church of England Primary School, penetration sealing fits best at the end of the summer works.

Questions we’re asked in Milton-under-Wychwood
What happens to BS 476 references for fire stopping in Milton-under-Wychwood?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Will you take on work at estates like Wychwood Business Centre, close to Milton-under-Wychwood?
Yes, sites like Wychwood Business Centre are within our area, along with the rest of Milton-under-Wychwood. A few photographs and the unit address let us price the work.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Are you insured?
Yes. We are fully insured, including public liability cover.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
What we’re called out for in Milton-under-Wychwood
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Site and facilities staff are often the first to spot these:
- Hidden openings found during inspections
- Old intumescent sealant that has split away
- Builders’ foam or ordinary silicone in compartment walls
- Openings left by services added after handover
In a building such as Church of St Simon and St Jude, any service penetration through a fire-resisting wall should be sealed to the specified detail.

- How they handle RAMS and site documents
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
What happens if it’s left?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. For buildings around smaller places like Milton-under-Wychwood, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
