Fire stopping for commercial buildings in North Oxford
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. We work on service gaps in risers, linear gaps at wall heads and cable penetrations, and the usual reasons a site gets in touch are fire-rated sealant that has cracked or shrunk back and expanding foam used as fire stopping. Whoever orders the work in North Oxford, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Around North Oxford, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Penetration seals near North Oxford
North Oxford is about 54 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For an estates team at a campus like University of Oxford, 1.4 miles south of North Oxford, summer M&E works are typically followed by a round of penetration sealing. Workshops and IT rooms at colleges like Oxford Sixth Form College, 1.6 miles south of North Oxford, are re-serviced often, leaving penetrations to seal.

How the job changes by surface
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 first.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, with backing added if the detail requires it.
How the quote is worked out
To price the job, we consider:
- How accessible the joints are
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
- Travel to remote or island sites
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
- Specification clauses that apply
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email us with what you know.
Doing it in-house
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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. For a job in North Oxford, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work
- Confirm the product named in the specification

Your questions answered
Can you work at a site such as Jordan Hill Business Park, by North Oxford?
Yes. We cover North Oxford and the area around it, including industrial estates, business parks and retail parks such as Jordan Hill Business Park. Photos and a short description are enough for a first look.
Can you work on a hospital site such as John Radcliffe Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months on every job.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details for a fixed quote. We can follow the services contractor floor by floor keeping pace with the programme.
What do BS EN 1366-3 and BS EN 13501-2 mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.
Common problems we fix in North Oxford
Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access usually bring them to light.
Site and facilities staff are often the first to spot these:
- Expanding foam used as fire stopping
- Fire stopping installed outside its tested range
- Damaged fire seals in risers and voids
- Open linear gaps along the top of fire-resisting walls
Tenant changes at parks like Jordan Hill Business Park (1.4 miles north of North Oxford) bring new data and services, and openings through fire-resisting walls need the specified seal.
What your quote should include
- What site paperwork they can supply
- How the joint faces will be prepared and primed
- Their approach to joint depth and backing
- How the existing material will be dealt with
Why deal with it now?
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. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
