Fire stopping in Covent Garden: the local picture

With tenants changing and fit-outs following, London buildings see service routes altered again and again. We install fire-rated sealant where it is specified and work within the building manager’s permit system. Fire stopping of openings and penetrations in England falls under Approved Document B. 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.

Workshops and IT rooms at colleges like Kensington College of Business, under half a mile to the north-east of Covent Garden, are re-serviced often, leaving penetrations to seal. Large healthcare estates like Royal London Hospital for Integrated Medicine, 0.6 miles to the north of Covent Garden, change their services often, so penetration seals are worth checking after M&E work.

Covent Garden is about 1 mile east of City of Westminster, in Greater London. Commercial clients in Covent Garden can call on us for service penetrations. Across Greater London, 764 places are covered, Covent Garden among them.

Anyone looking for fire stopping in W1F, W1D and W1T gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Among the streets we cover are Duck Lane, Drury Lane and New Square. You will find Covent Garden on or near the A301 and A400, so getting applicators and materials to site is simple. Nearby places we also cover include Seven Dials (1 mile west), Aldwych (1 mile east), Adelphi (1 mile south), St Giles (1 mile north-west) and Clare Market (1 mile north-east). Bigger towns within reach include Kensington (4 miles west), Walthamstow (7 miles north-east), Hampstead (4 miles north-west), Ruislip (13 miles west), Stockwell (3 miles south) and Orpington (13 miles south-east).

Fire stopping in Covent Garden

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, often unnoticed. Those on your schedule are closed with the specified product. We work on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the failures we’re asked to look at most are unsealed joints where partitions meet the slab and fire-rated sealant that has cracked or shrunk back. A single leaking joint is often how a building in Covent Garden first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.

Our workmanship is guaranteed for 12 months, in Covent Garden as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after the joints

A few simple habits keep the new joints working:

  • Check risers and ceiling voids after each round of works
  • Arrange inspection before areas are covered up
  • Leave fire sealant to cure fully before covering it
  • Brief every trade that openings they make must be sealed

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

FAQs: Covent Garden

Do you cover business parks and estates near Covent Garden, such as Grand Vitesse Industrial Estate?

Yes. We cover Covent Garden and the area around it, including industrial estates, business parks and retail parks such as Grand Vitesse Industrial Estate. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Will you plan work around the academic year at somewhere like King's College London?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact.

Are you members of a third-party fire-stopping installer scheme?

No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Do you work in Covent Garden?

Yes. We take on work across Covent Garden.

What do you charge?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

Honest limits

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

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.

Where we work in Covent Garden

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

Signs you need fire stopping in Covent Garden

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Look out for the following:

  • Fire seals cut back for extra cables and never reinstated
  • Service penetrations left open after M&E works
  • Head-of-wall gaps with no fire seal
  • Non-fire-rated filler around services

In a retail centre such as Brunswick Centre, 0.8 miles to the north of Covent Garden, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

How to choose a sealant contractor

Our process

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Covent Garden can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Tell staff and tenants when we will be in
  • Arrange parking or a loading space
  • Let us know about inductions and permits

Advice

When to bring in a specialist

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.

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.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
