How we handle fire stopping in Kirtlington

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are seals that don’t match their tested detail and unsealed penetrations discovered above suspended ceilings. Most enquiries from Kirtlington start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural conversions around Kirtlington can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Questions about Kirtlington

How does the move away from BS 476 affect penetration seals in Kirtlington?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is a hospital such as Bicester Community Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Do you work in Kirtlington?

Yes. Kirtlington is in our area and the rest of Oxfordshire, within our coverage of Greater London, South East England and Scotland. For a quote, call the office on 01277 525 020 or email us.

Can the building stay open while you work?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Fire doors, dampers or other fire safety equipment
  • Writing the fire-stopping specification
  • Signing off or certifying a building’s fire stopping

If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Where we work in Kirtlington

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

Fire-rated sealing for Kirtlington buildings

At about 57 miles from central London, Kirtlington is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Holiday works at schools like Kirtlington Church of England Primary School often leave service openings to seal before pupils return. Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. On a site such as Business Park, which lies south-east of Kirtlington, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Kirtlington is about 6 miles west of Bicester, in Oxfordshire.

Why deal with it now?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. 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. For buildings around smaller places like Kirtlington, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. 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.

What you get with us

  • Fixed quotes based on photos, drawings or a visit
  • Constructionline member
  • Commercial sealant work since 2005
  • CHAS accredited contractor

See our cost guide or our accreditations.

After the work

Once the work is signed off, a little attention goes a long way:

  • Check risers and ceiling voids after each round of works
  • Don’t let anyone top up a fire seal with the wrong product
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • File the specified details where the next contractor can find them

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Smaller jobs around Kirtlington can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Send your site hours and access windows
  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
