Questions about Silvertown
Is Greenshields Industrial Estate, near Silvertown, within your area?
Yes. Our area takes in Silvertown and its surroundings, with estates and business parks such as Greenshields Industrial Estate included. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Silvertown?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Fire stopping in Silvertown
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. Most enquiries involve fire sealant pulled out of the opening and damaged fire seals in risers and voids, across cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations. One point of contact handles commercial sealant work in Silvertown from the first photos to the final walk-round, whether it’s one building or several.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Common problems we fix in Silvertown
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position.
Look out for the following:
- Expanding foam used as fire stopping
- Penetration schedules that need working through
- Unsealed openings around new pipes and cables
- Openings found when ceilings come down for a refit
Workshops and IT rooms at colleges like New City College, 2.1 miles west of Silvertown, are re-serviced often, leaving penetrations to seal.
What to look for in a quote
- How joint depth will be controlled
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint
- Are they CHAS accredited or on Constructionline?
Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Walls or floors that aren’t fire-resisting to begin with
- Deciding what a wall or floor needs, which belongs to the designer
- Approving the work on behalf of building control
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. In Silvertown, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- 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.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Tell staff and tenants when we will be in
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand

Quoting for work in Silvertown
Quotes vary with the job. It mainly depends on:
- Distance, for remote addresses
- How accessible the joints are
- How much existing material needs removing
- Induction, permit and paperwork requirements
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
To price the job accurately, we need to understand the site. Send us:
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
- The postcode of the building
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Fire stopping in Silvertown: the local picture
Silvertown has five care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. A good number of hotels sit less than 2 miles from Silvertown. 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.
Industrial units on estates such as Greenshields Industrial Estate, less than half a mile to the west of Silvertown, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. At a university such as Ravensbourne University London (1.1 miles west of Silvertown), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
