How we handle fire stopping in North Greenwich
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in North Greenwich and nearby. The enquiries we see most involve open linear gaps along the top of fire-resisting walls and fire-stopping items raised at inspection or handover, across joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and cable penetrations. Facilities teams, main contractors and managing agents in North Greenwich tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In a London area such as North Greenwich, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

General trades versus a specialist
Redoing a failed joint usually 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.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Openings that need collars, wraps, batts or boards rather than sealant
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Fire risk assessments, a job for a competent assessor
If you’re not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Service gaps in risers
How the job changes by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.
What affects the price in North Greenwich
These are the things that shape the price:
- Specialist products, such as fire-rated or hygienic sealants
- Quantities, in metres or numbers
- Phasing around occupants
- How much existing material needs removing
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
What to include in your enquiry
A few photos plus some basic facts will normally do. It helps to include:
- A wide shot and a close-up of the area
- The site address and postcode
- Anything awkward about access or site hours
- Specification clauses that apply
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Diagnose, treat, sign off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Planning a London job such as one in North Greenwich starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Confirm the product named in the specification
- Arrange parking or a loading space
- Send asbestos survey details if the building is pre-2000

Advice
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Foam or ordinary sealant is never a fire-seal repair
- Treat an open penetration as a priority repair
- Ask the designer to confirm details early on refits
- Keep product data and details in the fire safety file
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.
North Greenwich: questions and answers
Can you work at a site such as Brookmarsh Industrial Estate, by North Greenwich?
Yes. Our area takes in North Greenwich and its surroundings, with estates and business parks such as Brookmarsh Industrial Estate included. A few photographs and the unit address let us price the work.
Can you work around term dates at a campus such as University of Greenwich - Greenwich Campus?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you cover North Greenwich?
Yes. North Greenwich falls within our area, and the simplest way to start is to phone 01277 525 020 or send photos by email.
What changes on 2 September 2029?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, subject to transitional arrangements. Scotland follows its own Technical Handbook.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Fire stopping around North Greenwich: what changes locally
Plenty of hotels sit less than 2 miles from North Greenwich. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
For a hospital such as Blackheath Hospital, which lies south-east of North Greenwich, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. For an estates team at a campus like University of Greenwich - Greenwich Campus, 0.7 miles south-east of North Greenwich, summer M&E works are usually followed by a round of penetration sealing. Where a unit on an estate such as Brookmarsh Industrial Estate, 0.7 miles to the south of North Greenwich, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
North Greenwich is about 1 mile north-west of Greenwich, in Greater London. Across the E14 postcode area, 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, from busy centres to rural villages.
