Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Walls or floors that aren’t fire-resisting to begin with
- Reviewing a building’s overall fire safety
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
Joints and surfaces we work on
- Cable penetrations
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Service gaps in risers
About our fire stopping in Barbican Estate
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Most enquiries involve openings left by services added after handover and hidden openings found during inspections, across service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads. Searching for sealant specialists in Barbican Estate? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
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.
A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email us and we will arrange a return visit.

How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. For a job in Barbican Estate, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Move anything stored against the joints
- Let building users know which areas are affected
- Let us know about inductions and permits

Your questions answered
Can work in a care setting near Barbican Estate go ahead while residents are there?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Does your area include sites such as Southwark Bridge Business Centre, near Barbican Estate?
Yes. We cover Barbican Estate and the area around it, including industrial estates, business parks and retail parks such as Southwark Bridge Business Centre. Send details of the unit and the work through our quote form for a quick quote.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Will you write the fire-stopping specification?
No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Look above ceilings when tiles are lifted for other jobs
- File the specified details where the next contractor can find them
- Foam or ordinary sealant is never a fire-seal repair
- Leave fire sealant to cure fully before covering it
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
Quoting for work in Barbican Estate
What shapes the price:
- Any access equipment needed
- Backing rod, priming and other preparation
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
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
There’s no need for a formal survey. These details are enough to start:
- Access details, including height
- The type of building and who uses it
- Clear photographs of the problem areas
- When you need the work done
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Common problems we fix in Barbican Estate
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.
It’s worth sending us details if you spot any of the following:
- Fire stopping installed outside its tested range
- Fire-stopping items raised at inspection or handover
- Damaged fire seals in risers and voids
- Openings found when ceilings come down for a refit
For a site team at a college like London College of Fashion, which lies north-east of Barbican Estate, fire-rated sealing is best scheduled after the summer works.

Compartment walls and floors in Barbican Estate
Barbican Estate has plenty of hotels close by, all within 2 miles. 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. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.
For an estates team at a campus like The University of Law (under half a mile north-east of Barbican Estate), summer M&E works are normally followed by a round of penetration sealing. At a healthcare site like St Bartholomew's Hospital, under half a mile south-west of Barbican Estate, new services through compartment walls are a constant, and each needs the specified seal.
