Where services cross fire walls in Hackney Marshes
The 2 miles around Hackney Marshes include 28 care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. A 2-mile radius around Hackney Marshes 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.
Hospital estates such as Homerton University Hospital (to the south-west of Hackney Marshes) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Colleges such as International College of Musical Theatre (0.9 miles south of Hackney Marshes) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Hackney Marshes is about 1 mile north-east of Homerton, in Greater London. Anywhere in E5, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places.

How we handle fire stopping in Hackney Marshes
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. We work on joints between fire-resisting walls and floors, cable penetrations and service gaps in risers, and the failures we are asked to look at most are fire-rated sealant that has cracked or shrunk back and seals that don’t match their tested detail. A single leaking joint is often how a building in Hackney Marshes 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.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Signs you need fire stopping in Hackney Marshes
Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.
Look out for the following:
- Service penetrations left open after M&E works
- Penetration schedules that need working through
- Improvised or mixed-product fire seals
- Seals disturbed by maintenance and left open
Tenant changes at centres like Leyton Mills Retail Park (to the east of Hackney Marshes) often mean new services through walls between units.
What to look for in a quote
- How they’ll work around occupants
- The terms of the workmanship guarantee
- The named product and why it was chosen
- Will failed sealant be removed rather than covered?
Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Reviewing a building’s overall fire safety
- Deciding what a wall or floor needs, which belongs to the designer
- Openings that need collars, wraps, batts or boards rather than sealant
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.
What we seal
- Cable penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Why act early in Hackney Marshes
Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. For a job in Hackney Marshes, access comes first. Give us the hours we can be on site and we will schedule to suit.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Arrange parking or a loading space
- Tell us your opening times and when work is allowed

FAQs: Hackney Marshes
Can work in a care setting near Hackney Marshes go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
How does the move away from BS 476 affect penetration seals in Hackney Marshes?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How much does the work cost?
Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or send photos by email with a description of the work.
Is Hackney Marshes in your area?
Yes. Hackney Marshes is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or email a schedule or drawings.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
How the job changes by surface
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter.
