Fire stopping in Haggerston
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. 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, joints between fire-resisting walls and floors and pipe penetrations, and what we are called in for most is old intumescent sealant that has split away and seals that don’t match their tested detail. Most enquiries from Haggerston start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the job changes by surface
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We follow your schedule area by area and tell you about openings outside the list.

Cost factors for service penetrations
Your fixed quote is built from the real scope. It allows for:
- Working within restricted access windows
- The total length or number of joints
- Backing rod, priming and other preparation
- Access and working height
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Where the site is, with the postcode
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
- The product your specification calls for

Fire-rated sealing for Haggerston buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. The area within 2 miles of Haggerston holds a good number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
On a hospital site such as Mildmay Mission Hospital (0.5 miles south of Haggerston), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Industrial units on estates such as Bayford Street Industrial Centre, 0.9 miles to the north-east of Haggerston, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
Haggerston is about 1 mile east of Hoxton, in Greater London. Any commercial site in Haggerston is covered, for single jobs and planned programmes alike. Haggerston is one of 764 places in Greater London on our list for service penetrations.
If you need fire stopping in N1, E2 and E8, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Streets here include Hyde Road, Glebe Road and Ufton Road. Access to Haggerston is via the A1208. We also cover Hoxton (1 mile west), Shoreditch (1 mile south), De Beauvoir Town (1 mile north), Kingsland (1 mile north) and Bethnal Green (1 mile south-east) for service penetrations. A short drive away, we cover London (3 miles south), City of Westminster (4 miles south-west), Marylebone (3 miles west), Kensington (6 miles south-west), Walthamstow (4 miles north-east) and Hampstead (5 miles west).
Landmarks near Haggerston
Around Haggerston, our work takes us to commercial buildings near The Prince's School of Traditional Arts, Haggerston Park and Stag's Head pub. Nearby too are Bishopsgate Institute Special Collections and Archives (1.1 miles south) and The Bridge Academy (less than half a mile north-east). Haggerston has its own railway station: Hoxton station. Well-known places in the area include Museum of the Home (under half a mile south) and Montfichet's Tower (1.8 miles south-west). Green spaces nearby include St. James's Park Lake and Barnsbury Wood.
Leave it or put it right?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Your questions answered
Do you cover business parks and estates near Haggerston, such as Bayford Street Industrial Centre?
Yes. Estates, retail parks and business parks around Haggerston, Bayford Street Industrial Centre among them, are all within reach. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you work on a hospital site such as Mildmay Mission Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is BS 476 being phased out?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, with transitional arrangements set by the Government. After that, the European classification under BS EN 13501-2 is the route. Your designer will choose products with the right evidence.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you cover Haggerston?
Yes. Sites across Haggerston are covered, and the same phone number covers every area.
Do you need fire stopping in Haggerston?
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access normally bring them to light.
If one of these sounds familiar, it’s time for a closer look:
- Fire-rated sealant that has cracked or shrunk back
- Penetration schedules that need working through
- Hidden openings found during inspections
- Expanding foam used as fire stopping
At a college such as New City College, which lies south of Haggerston, checking penetration seals after summer M&E works is good practice.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- How the joint faces will be prepared and primed
Our process
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 the job ends with a walk round and sign-off. In Haggerston, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- 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
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
- Tell staff and tenants when we will be in
