Questions we are asked in Barbican Estate
Is hospital work, at somewhere like St Bartholomew's Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Could you schedule work at a campus like The University of Law for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you work to our specification?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Can you work while the building is occupied?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
Construction mastic for commercial buildings in Barbican Estate
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you have bath and shower joints scraped during the final clean and perimeter gaps outside the sealant’s range, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Barbican Estate, that means joint design, primers and backing rod as standard.
Every London site, Barbican Estate included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
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.

From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Drawings, the sealant specification and your programme come to us for pricing.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Let us know about inductions and permits
- Share the asbestos register for older buildings

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Sites and facades in and around Barbican Estate
A 2-mile radius around Barbican Estate takes in a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The ULEZ covers the whole of Greater London, Barbican Estate included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
For contractors refurbishing units at places like Southwark Bridge Business Centre (1.1 miles south of Barbican Estate), the mastic covers cladding panels, roller-door and window perimeters. For a contractor working at a hospital such as St Bartholomew's Hospital, which lies south-west of Barbican Estate, perimeter and facade sealing is planned around patients and deliveries. Further education sites such as London College of Fashion, 0.8 miles to the north-east of Barbican Estate, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Barbican Estate is about 1 mile north of London, in City of London. Barbican Estate sits inside our coverage and the rest of City of London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across City of London, 7 places are covered, including Barbican Estate.

What sets the cost
To price the job, we consider:
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- The total length or number of joints
- Backing rod, priming and other preparation
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- How the joints are reached, and at what height
- When you need the work done
- Asbestos survey details if the building is older
- The type of building and who uses it
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Why act early in Barbican Estate
A quick bead over a damaged joint can get an area past inspection, but it won’t last. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Why appoint us
- Clear, fixed quotes
- Products installed to the manufacturer’s instructions
- 12-month guarantee on workmanship
- Constructionline member

What else we do in Barbican Estate
What the job involves on each surface
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent, plot by plot or floor by floor.
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Damage to finishes by other trades after we’ve sealed
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Joint design decisions that belong to the architect or engineer
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
Surfaces we seal
- Brick and block movement joints
- Sanitary and kitchen joints
- Cladding and panel joints
- Internal decorators’ caulk
- Floor and skirting junctions
- Window and door perimeters
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Share drawings and the specification as soon as possible
- Record the products used in the O&M file
- Ask installers to correct oversized gaps first
- Bring the mastic contractor in after the last trades are through
Expect some settlement in the first months. The right product in each joint copes with that while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out and keeps handover on track.
