Fire stopping for businesses in Eynsham

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What happens if it’s left?

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why us?

  • Public liability insurance in place
  • CHAS accredited contractor
  • Our applicators hold CSCS cards
  • Old sealant cut out, never sealed over

About our fire stopping in Eynsham

No fire sealant works on its own: 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. If you’re dealing with seals that don’t match their tested detail and service penetrations left open after M&E works, we can help, on small duct penetrations where the tested detail allows, service gaps in risers and joints between fire-resisting walls and floors alike. For commercial sealant work in Eynsham, you deal with one contact from quote to sign-off, whether it’s one building or several.

In places the size of Eynsham, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Maintenance after handover

For the best life from the joints:

  • Look above ceilings when tiles are lifted for other jobs
  • Agree the fire-stopping specification before services go in
  • Foam or ordinary sealant is never a fire-seal repair
  • Put resealing into every M&E and fit-out package

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.

Fire-rated sealing for Eynsham buildings

For England, the fire stopping of penetrations is dealt with in 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. Our part stays the same: the specified product, installed to its tested detail. Central London is about 58 miles from Eynsham. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

For a hospital such as Radcliffe Infirmary (5.1 miles east of Eynsham), penetration sealing is normally phased ward by ward, with infection-control rules agreed first. For an estates team at a campus like Azad University in Oxford, which lies south-east of Eynsham, summer M&E works are typically followed by a round of penetration sealing. Older community buildings such as Church of St Leonard that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Eynsham is about 5 miles east of Witney, in Oxfordshire. We send applicators to Eynsham for service penetrations. Our Oxfordshire coverage takes in 423 places. Our Oxford page has more on work in that area (7 miles or so).

Work on service penetrations is covered throughout OX29, whatever the building. If your site is on High Street, Station Road and Back Lane or close by, we can quote for service penetrations. Nearby places we also cover include Swinford (1 mile south-east), Cassington (2 miles north-east), Farmoor (2 miles south-east), Sutton (2 miles south-west) and Filchampstead (3 miles south-east) for service penetrations. Further afield, our area takes in Oxford (7 miles east), Didcot (13 miles south-east), Bicester (13 miles north-east), Abingdon-on-Thames (8 miles south-east), Witney (5 miles west) and Carterton (9 miles west).

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. If neighbouring businesses or buildings around Eynsham need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What we can’t put right

Being straight saves everyone time. Fresh joints won’t solve:

  • Signing off or certifying a building’s fire stopping
  • Gaps in walls that were never built as compartment walls
  • Plastic pipes whose detail calls for a collar or wrap

Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly.

Where we work in Eynsham

  • Small duct penetrations where the tested detail allows
  • Linear gaps at wall heads
  • Joints between fire-resisting walls and floors
  • Service gaps in risers
  • Cable penetrations
  • Pipe penetrations

Questions about Eynsham

Do you take on work at healthcare sites like Radcliffe Infirmary?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work at a site such as Oasis Business Park, by Eynsham?

Yes. Estates, retail parks and business parks around Eynsham, Oasis Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Will fire-rated sealant work on every penetration?

No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed, specified by your designer.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Is the BS 476 change in 2029 relevant to fire stopping?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. Scotland follows its own Technical Handbook.

Is fire stopping in Scotland covered by different guidance?

Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Either way, we install the specified sealant to its tested detail.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months on every job.

Different surfaces, different methods

Metal pipes

Heat travels along metal pipework. We follow whatever the detail requires and flag anything we can’t match.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.
