Fire stopping for Greenwich sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself typically taking anything from one day to a planned run of visits, depending on the number of seals and the access. 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 start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Getting the site ready
- Explain the parking and delivery arrangements
- Have the specification and drawings to hand
- Warn occupants and staff about the work

How we handle fire stopping in Greenwich
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call 01277 525 020 or email us with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on service gaps in risers, pipe penetrations and cable penetrations, and what we are called in for most is fire sealant pulled out of the opening and openings found when ceilings come down for a refit. Facilities teams, main contractors and managing agents in Greenwich tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
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 will hear it from us.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Other services in Greenwich
Surface by surface
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
How the quote is worked out
We price every job individually. The main factors are:
- Distance, for remote addresses
- The product specified
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- What the building is and how it’s used
- When you need the work done
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, ring 01277 525 020 or use the quote form.
Fire stopping in Greenwich: the local picture
There are four care or nursing homes within about 2 miles of Greenwich. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
Wherever services are added at a hospital such as Blackheath Hospital, 1.2 miles south of Greenwich, the compartment line has to be made good with the specified product. On a site such as Greenwich Centre Business Park, 0.7 miles to the west of Greenwich, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
Greenwich is about 4 miles east of London, in Greater London. Any commercial site in Greenwich is covered, for single jobs and planned programmes alike. Greenwich is one of 764 places in Greater London on our list.
Work on service penetrations is covered throughout SE10, SE3 and SE8. We cover commercial and managed buildings on Cade Road, Webb Road and Creek Road and the roads nearby. Greenwich sits on or close to the A2203 and A2211. If your building is just outside Greenwich, we cover Maze Hill (1 mile north-east), Vanbrugh Park Estate (1 mile east), Blackheath (1 mile south-east), Westcombe Park (1 mile east) and Isle of Dogs (1 mile north-west). Nearby towns on our patch include London (4 miles west), City of Westminster (7 miles west), Marylebone (7 miles west), Kensington (9 miles west), St Pancras (6 miles north-west) and Shoreditch (5 miles north-west).
Near you in Greenwich
In Greenwich, that means premises near The Plume of Feathers pub, John Roan School and Royal School of Naval Architecture and Marine Engineering and the streets around them.

A little further out are Greenwich Castle (under half a mile south-west) and Greenwich District Hospital (0.5 miles north-east). For a walk, there’s Tower Hill and Creekside Discovery Centre.
FAQs: Greenwich
Is a hospital such as Blackheath Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work in occupied care homes around Greenwich?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Do you approve fire stopping for building control?
No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the products and details used, and you can tell us what other records you need at quote stage.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
Can you tell us what fire stopping our building needs?
No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or use the quote form. Include photographs or drawings if you have them.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Writing the fire-stopping specification
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Building owners, agents and FMs in Greenwich
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Greenwich. One quote can cover more than one site, which keeps the paperwork simple.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Do you need fire stopping in Greenwich?
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
If one of these sounds familiar, it’s time for a closer look:
- Non-fire-rated filler around services
- Openings left by services added after handover
- Unsealed joints where partitions meet the slab
- Damaged fire seals in risers and voids
For an estates team at a campus like University of Greenwich, less than half a mile to the north-west of Greenwich, summer M&E works are typically followed by a round of penetration sealing.
