Fire stopping in Telegraph Hill
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. The enquiries we see most involve snag lists that include open service penetrations and openings left by services added after handover, across cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, in Telegraph Hill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Gaps in walls that were never built as compartment walls
- Issuing fire ratings or certificates for seals
- Fire doors, dampers or other fire safety equipment
If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think.
Surfaces we seal
- Pipe penetrations
- Linear gaps at wall heads

How the quote is worked out
We price every job individually. The things that drive the figure:
- How accessible the joints are
- How much existing material needs removing
- Backing rod, priming and other preparation
- Working within restricted access windows
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Details that help us quote
However big the job, the same details help:
- The type of building and who uses it
- Whether an asbestos survey exists
- Anything awkward about access or site hours
- The postcode of the building
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Our process
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a job in Telegraph Hill, access comes first. Send the building rules and access times with your enquiry.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.

What else we do in Telegraph Hill
Service penetrations in Telegraph Hill buildings
The 2 miles around Telegraph Hill include two care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
At a healthcare site like University Hospital Lewisham, 1.4 miles to the south-east of Telegraph Hill, new services through compartment walls are a constant, and each needs the specified seal. At a college such as Christ the King: Aquinas Sixth Form College, under half a mile to the north-east of Telegraph Hill, checking penetration seals after summer M&E works is good practice. In a hotel such as Peckham Rooms Hotel, 1 mile north-west of Telegraph Hill, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
Telegraph Hill is about 1 mile south-west of New Cross, in Greater London. If you’re looking for fire stopping in Telegraph Hill, we can help, as we do across Greater London. Across Greater London, 764 places are covered, Telegraph Hill among them.
If you need fire stopping in SE4, SE15 and SE14, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

What’s near Telegraph Hill
Locally, jobs take us to sites close to Fordham Park and The Brockley Barge pub and the streets around them. There’s a railway station in Telegraph Hill itself: Brockley station. Other landmarks nearby include Southwark Adult Education Institute (0.6 miles north-west) and Lewisham Shopping Centre (1.4 miles east). Not far away are St. James's Park Lake and New Cross Gate Cutting.
Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Why it’s worth doing now in Telegraph Hill
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. 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 Telegraph Hill takes effort, so it makes sense to deal with every failing joint while access is in place.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
