Common questions from Newington Green clients
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Newington Green?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
How do you choose the sealant?
A specification, where there is one, decides it. 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 in Newington Green, done properly
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. We work on linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are seals that don’t match their tested detail and damaged fire seals in risers and voids. A specialist sealant contractor works differently from a general builder: in Newington Green, that means joint design, primers and backing rod as standard.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we’ll arrange a return visit.

Honest limits
Honesty saves time and money. Fresh joints won’t solve:
- Large openings beyond what any sealant detail covers
- Fire risk assessments, a job for a competent assessor
- Gaps in walls that were never built as compartment walls
If you’re not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer before you book.
What we seal
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Pipe penetrations
Why act early in Newington Green
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Failed sealant in a building in Newington Green can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Service penetrations in Newington Green buildings

Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Hospital estates such as Moorfields Eye Hospital (City Road campus), 1.7 miles to the south of Newington Green, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- The type of building and who uses it
- Clear photographs of the problem areas
- When you need the work done
- The product your specification calls for
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. In Newington Green, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Point out any areas we must not close

Signs you need fire stopping in Newington Green
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it and has to be removed.
These are often picked up first by site or facilities staff:
- Fire stopping installed outside its tested range
- Service penetrations left open after M&E works
- Fire-stopping items raised at inspection or handover
- Old intumescent sealant that has split away
At a college such as City & Islington College, 1.2 miles to the north-west of Newington Green, checking penetration seals after summer M&E works is good practice.
What your quote should include
- How they handle RAMS and site documents
- Are they CHAS accredited or on Constructionline?
- How they’ll work around occupants
- Proof of insurance
Different surfaces, different methods
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.
