Fire stopping for Islington sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
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. All of Greater London is in the ULEZ, and kerbside space in Islington can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Tell us which areas need to stay in use
- Confirm the product named in the specification
Getting a fixed quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Fire stopping for commercial buildings in Islington
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. We work on cable penetrations, service gaps in risers and pipe penetrations, and the failures we’re asked to look at most are builders’ foam or ordinary silicone in compartment walls and open linear gaps along the top of fire-resisting walls. A single leaking joint is often how a building in Islington first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. Our part is installing the specified fire-rated sealant; tell us what records you need and we’ll confirm with the quote.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

FAQs: Islington
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Can you work at a site such as Roman Way Industrial Estate, by Islington?
Yes, sites like Roman Way Industrial Estate are within our area, along with the rest of Islington. Photos and a short description are enough for a first look.
Is the BS 476 change in 2029 relevant to fire stopping?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. The European route, BS EN 13501-2, then applies. Your designer will choose products with the right evidence.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Do you seal openings left by new services?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see.
How do we ask for a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email the details over. Include photos or drawings if you have them.
Do you design or specify fire stopping?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Where services cross fire walls in Islington
The 2 miles around Islington include four care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. 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 Islington. 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.
Shop fits in centres such as Brunswick Centre (to the south-west of Islington) can bring new services through fire-resisting walls between units, which then need the specified seal. For an estates team at a campus like Paris Dauphine University - London Campus, 0.5 miles south of Islington, summer M&E works are normally followed by a round of penetration sealing. For a site team at a college like City and Islington College, 0.6 miles to the south of Islington, fire-rated sealing is best scheduled after the summer works.
Islington is about 3 miles north-east of City of Westminster, in Greater London. Across the N1 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Islington is one of 764 places we cover in Greater London.

Why it’s worth doing now in Islington
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. In Islington, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What sets the cost
The price varies from site to site. It mainly depends on:
- Distance, for remote addresses
- Phasing around occupants
- Whether old sealant has to be cut out first
- Joint width, depth and condition
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
What we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
- Where the site is, with the postcode
- Access details, including height
For a fixed quote, call 01277 525 020 or send photos by email. You can also send details through our quote form.
When to bring in a specialist
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. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
How the job changes by surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness first.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Put resealing into every M&E and fit-out package
- Keep general-purpose fillers away from compartment walls
- Report damaged or disturbed seals as soon as they’re spotted
- Arrange inspection before areas are covered up
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
