Fire stopping for Shepherd's Bush sites

How we handle fire stopping in Shepherd's Bush

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. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers, and what we’re called in for most is unsealed openings around new pipes and cables and damaged fire seals in risers and voids. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Shepherd's Bush, that means joint design, primers and backing rod as standard.

London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.

We sign every job 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.

Quoting for work in Shepherd's Bush

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Any access equipment needed
  • Which sealant the job calls for
  • The size and state of each joint
  • Site requirements such as inductions and permits

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • Your programme or deadline
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, phone 01277 525 020 or email a schedule or drawings.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

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

Fire-rated sealing for Shepherd's Bush buildings

A 2-mile radius around Shepherd's Bush takes in plenty of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. In England, Approved Document B covers fire stopping of 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. What we install is set by the specification, and it goes in to the tested detail.

Campus buildings at universities such as BPP University, less than half a mile north-west of Shepherd's Bush, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Workshops and IT rooms at colleges like St Charles Catholic Sixth Form College, 1.1 miles to the north of Shepherd's Bush, are re-serviced often, leaving penetrations to seal. Hospital estates such as Queen Charlotte's & Chelsea Hospital (1.1 miles north-west of Shepherd's Bush) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Shepherd's Bush is about 1 mile west of Kensington, in Greater London. Commercial clients in Shepherd's Bush can call on us for service penetrations. Our Greater London coverage takes in 764 places.

Work on service penetrations is covered throughout W12, W11 and W14, for business premises of every kind. If your site is on Bard Road, Stowe Road and Wells Road or close by, we can quote for service penetrations. Shepherd's Bush sits on or close to the A402, which helps when planning parking and deliveries for the job. Close to Shepherd's Bush, our area also takes in White City (1 mile north), Holland Park (1 mile east), Notting Hill (1 mile north-east), Kensington (1 mile east) and Notting Dale (1 mile north-east). Bigger towns within reach include London (5 miles east), City of Westminster (3 miles east), Marylebone (3 miles east), St Pancras (5 miles east), Shoreditch (6 miles east) and Walthamstow (10 miles north-east).

Around Shepherd's Bush

A little further out are West 12 Shepherds Bush (less than half a mile east) and Culture House (less than half a mile west). Not far away are WWT London Wetland Centre and The Long Water.

Questions we’re asked in Shepherd's Bush

Can you work around term dates at a campus such as BPP University?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work on a hospital site such as Queen Charlotte's & Chelsea 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.

Do you approve fire stopping for building control?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.

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

It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance.

Do you work in Shepherd's Bush?

Yes. Sites across Shepherd's Bush are covered.

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.

What site paperwork can you supply?

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

Leave it or put it right?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Getting scaffold, permits or access booked in Shepherd's Bush takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why clients in Shepherd's Bush choose us

What sealant work can’t fix

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Large openings beyond what any sealant detail covers
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Approving the work on behalf of building control

If you are not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a job in Shepherd's Bush, access comes first. Send the building rules and access times with your enquiry.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Agree which areas must stay open
  • Confirm the product named in the specification
  • Share your working hours and any access restrictions

Related advice

What the job involves on each surface

Drylining partitions

Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers first.

Metal pipes

Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.
