About our fire stopping in Finsbury
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or email drawings and photos with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve damaged fire seals in risers and voids and snag lists that include open service penetrations, on pipe penetrations, cable penetrations and small duct penetrations where the tested detail allows. For commercial sealant work in Finsbury, you deal with one contact from quote to sign-off, whether it’s one building or several.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. 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.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Fire stopping in Finsbury: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. 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 an estates team at a campus like The University of Law (under half a mile east of Finsbury), summer M&E works are normally followed by a round of penetration sealing. Workshops and IT rooms at colleges like London College of Fashion, 0.6 miles east of Finsbury, are re-serviced often, leaving penetrations to seal. For a building at a site such as Southwark Bridge Business Centre (1.3 miles south of Finsbury), a check of penetration seals after each fit-out is good practice.
Finsbury is about 2 miles north of London, in Greater London. We send applicators to Finsbury for service penetrations, handled exactly as we handle every other area. Finsbury is one of 764 places in Greater London on our list for service penetrations.
We cover the EC1V, N1 and EC2A postcode districts for service penetrations. Among the streets we cover are Oat Lane, Long Lane and Love Lane, and sites on any of them can send details for a fixed quote. Access to Finsbury is via the A1 and A501. Close to Finsbury, our area also takes in St Luke's (1 mile north), Barbican Estate (1 mile south), City of London (1 mile south), Bishopsgate (1 mile south-east) and Shoreditch (1 mile east). A short drive away, we cover City of Westminster (3 miles west), Kensington (5 miles west), Walthamstow (5 miles north-east), Hampstead (4 miles north-west), Ruislip (14 miles west) and Brompton (4 miles south-west).
What’s near Finsbury
Around Finsbury, our work takes us to commercial buildings near Artillery Ground, Barts Health Archives and Charterhouse Square School and the streets around them. Other local landmarks include The Jugged Hare pub (less than half a mile south), St Mary-at-Hill (0.9 miles south-east) and Central Foundation Boys' School (under half a mile north-east).

Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Finsbury. Several sites can go on one quote, which keeps the paperwork simple.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Why it’s worth doing now in Finsbury
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 and avoids a much larger catch-up later. Getting scaffold, permits or access booked in Finsbury takes effort, so it makes sense to deal with every failing joint while access is in place.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Your questions answered
Can you work on a hospital site such as Moorfields Eye Hospital (City Road campus)?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is Southwark Bridge Business Centre, near Finsbury, within your area?
Yes. We cover Finsbury and the area around it, including industrial estates, business parks and retail parks such as Southwark Bridge Business Centre. A few photographs and the unit address let us price the work.
Do you seal openings left by new services?
Yes, where there is a specification for those walls and floors. New services after M&E works often breach existing seals.
Is Finsbury in your area?
Yes. Finsbury falls within our area, and the simplest way to start is to call 01277 525 020 or email a schedule or drawings.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Will fire-rated sealant work on every penetration?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we flag those rather than improvise.

What sets the cost
Each job is priced on its own details. The main factors are:
- Backing rod, priming and other preparation
- Distance, for remote addresses
- Any access equipment needed
- The product specified
Pricing service penetrations depends on quantities, condition and access. Call for a quote.
Details that help us quote
However big the job, these details speed things up:
- What the building is and how it’s used
- Asbestos survey details if the building is older
- Any dates the work must fit around
- The product your specification calls for
To get a fixed quote, speak to us on 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we go through the drawings, schedule or specification for the seals.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Let building users know which areas are affected
- Share the asbestos register for older buildings
- Let us know about inductions and permits

Advice
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Keep general-purpose fillers away from compartment walls
- Get seals inspected before ceilings and boxing close
- Brief every trade that openings they make must be sealed
- Treat an open penetration as a priority repair
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
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.
