Fire stopping in Shoreditch
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Shoreditch. Most enquiries involve expanding foam used as fire stopping and fire-stopping items raised at inspection or handover, on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations. Most enquiries from Shoreditch 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.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Compartments and services around Shoreditch
There are plenty of hotels within about 2 miles of Shoreditch. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
Shop fits on retail sites such as Anchor Retail Park, 1.2 miles to the east of Shoreditch, can bring new services through fire-resisting walls between units, to be sealed with the specified product. For a hospital such as Mildmay Mission Hospital (less than half a mile north-east of Shoreditch), penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

Questions about Shoreditch
How does the move away from BS 476 affect penetration seals in Shoreditch?
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.
Could you schedule work at a campus like Northumbria University London Campus for the vacation?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Can you work while the building is occupied?
In most cases, yes. We phase the work so most of the building stays in use.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Leave it or put it right?
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. Getting scaffold, permits or access booked in Shoreditch takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

When to call us in Shoreditch
Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.
Site and facilities staff are often the first to spot these:
- Expanding foam used as fire stopping
- Penetration schedules that need working through
- Service penetrations left open after M&E works
- Fire seals cut back for extra cables and never reinstated
For a hotel such as Courthouse Hotel Shoreditch, which lies north-west of Shoreditch, penetration seals are worth checking after any refit or services upgrade.
What your quote should include
- Their approach to joint depth and backing
- Whether old or failed sealant will be cut out, not overlaid
- Will RAMS and insurance details be available?
- Do they follow the manufacturer’s priming guidance?
Different surfaces, different methods
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.
On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Flag any permit to work we’ll need
- Have the specification and drawings to hand
- Send your site hours and access windows
Getting a fixed quote
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Advice
When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Signing off or certifying a building’s fire stopping
- Reviewing a building’s overall fire safety
- Walls or floors that aren’t fire-resisting to begin with
If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer.
Surfaces we seal
- Service gaps in risers
- Linear gaps at wall heads
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
