Expansion joint sealing for commercial buildings in Seven Dials
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels. We will tell you if the edges need repairing before sealing. If you are dealing with brittle, chalky sealant on external joints and movement joints with split or torn sealant, we can help. A specialist sealant contractor works differently from a general builder: in Seven Dials, that means joint design, primers and backing rod as standard.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Seven Dials means thinking about access, loading times and the ULEZ as well as the joints.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we will come back to it.

Why it’s worth doing now in Seven Dials
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too and repeated access costs add up. We can price a patch and a full reseal side by side. Getting scaffold, permits or access booked in Seven Dials takes effort, so it makes sense to deal with every failing joint while access is in place.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What you get with us

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Planning a London job such as one in Seven Dials starts with access. Send the building rules and access times with your enquiry.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- For older buildings, check the asbestos register before work
- Have the specification and drawings to hand
- Arrange parking or a loading space

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Do you need expansion joint sealing in Seven Dials?
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.
Common reasons buildings call us in:
- Hardened, cracked sealant on exposed facades
- Joints where the bead has lost adhesion
- Leaks through car park deck joints onto the level below
- Movement joints with split or torn sealant
On industrial estates such as Grand Vitesse Industrial Estate (1.3 miles south-east of Seven Dials), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Honest limits
Honesty saves time and money. New sealant won’t cure:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Joints too narrow for the movement, which need redesigning by the engineer
- Damaged metal nosings or cover plates over a joint
If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think.
What we seal
- Car park decks and ramps

Cost factors for movement joints
What shapes the price:
- How accessible the joints are
- Location, for remote and island sites
- The size and state of each joint
- Specialist products, such as fire-rated or hygienic sealants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- Drawings or a marked-up plan, if available
- Your programme or deadline
- A wide shot and a close-up of the area
- What the building is and how it’s used
For a fixed quote, call 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. Our quote form is another easy route.
Common questions from Seven Dials clients
Can you take on a job at a hospital such as Royal London Hospital for Integrated Medicine?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Do you work in Seven Dials?
Yes. Seven Dials is in our area and the rest of Greater London. For a quote, ring 01277 525 020 or email a schedule or drawings.
Can you seal joints in cold or wet weather?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work, so we plan with the forecast in mind.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact.
