About our expansion joint sealing in Blackfriars
Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. We work on brickwork movement joints, cladding panel joints and blockwork control joints, and the failures we’re asked to look at most are leaks through car park deck joints onto the level below and hardened, cracked sealant on exposed facades. Searching for sealant specialists in Blackfriars? We’ve been sealing commercial buildings since 2005.
Areas such as a loading bay or car park deck in Blackfriars typically have to stay in use. We work through joints a section at a time, closing small areas in turn.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Joints that move: notes for Blackfriars
Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured. Blackfriars has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Retail centres such as Brunswick Centre (1.2 miles north-west of Blackfriars) have floors, service yards and car parks with joints under constant traffic. A campus such as Queen Mary's University West Smithfield Campus, less than half a mile to the north-east of Blackfriars, has long runs of movement joint in its buildings, decks and paving. Sites like St Bartholomew's Hospital (less than half a mile north-east of Blackfriars) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Blackfriars is about 1 mile north-west of London, in City of London. Commercial clients in Blackfriars use us for work on movement joints. Blackfriars is one of 7 places in City of London on our list.
Postcode districts covered here: SE1, EC1M and EC1N for movement joints. Among the streets we cover are Oat Lane, Bear Lane and Shoe Lane, and sites on any of them can send details for a fixed quote. Blackfriars sits on or close to the A4 and A40, which helps when planning parking and deliveries for the job. Sites close to Blackfriars are covered too, including Temple (1 mile west), Temple Bar (1 mile west), Bankside (1 mile south-east), Smithfield (1 mile north) and Clare Market (1 mile west).

Common questions from Blackfriars clients
Does your area include sites such as Grand Vitesse Industrial Estate, near Blackfriars?
Yes, sites like Grand Vitesse Industrial Estate are within our area, along with the rest of Blackfriars. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
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.
Can you quote from photographs?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can staff carry on working while you are here?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
Can you work on car park ramps and decks?
Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed.
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.

Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
How the job changes by surface
Podium joints
Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.
How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Planning a London job such as one in Blackfriars starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Flag any permit to work we will need
- Tell us your opening times and when work is allowed
- Tell staff and tenants when we’ll be in
Ask for a quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
What affects the price in Blackfriars
The price varies from site to site. Expect it to depend on:
- Location, for remote and island sites
- The site’s rules and procedures
- How much there is to seal
- Backing rod, priming and other preparation
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
What we need to price the job
To price the job accurately, we need to understand the site. Useful things to include:
- Your programme or deadline
- The asbestos register, for older buildings
- Whether the building will be occupied during the work
- The postcode of the building
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Keeping the joints sound
After handover, a little attention goes a long way:
- Note which joints were done, when, and with what
- Keep traffic off new joints until the cure time is up
- Treat a small split as a warning, not a cosmetic issue
- Raise snow-clearing blades over deck joints where possible
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers. Sealing early protects the edges.
