When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Leaks coming from the membrane rather than the joint seal
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Concrete or masonry repairs along the arrises

About our expansion joint sealing in Millbank
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors. If you’re dealing with new sealant over old, now failing and rain penetration at brick or block movement joints, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Millbank it comes down to the same thing: the right product in a properly prepared joint.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Common problems we fix in Millbank
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.
Typical triggers for a call:
- Water getting into the wall through a failed joint
- Joints packed with grit and debris
- Joints where the bead has lost adhesion
- Leaks through car park deck joints onto the level below
For an estate such as Gordon Hospital, which lies south of Millbank, the joints in ramps, decks and long building elevations all need attention over time.
What to look for in a quote
- Who will actually carry out the work
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
- Is the sealant right for the movement and the substrate?
Cost factors for movement joints
A fixed quote reflects the actual work. It takes account of:
- Joint width, depth and condition
- The product specified
- Whether old sealant has to be cut out first
- How accessible the joints are
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- How the joints are reached, and at what height
- Where the site is, with the postcode
- The product your specification calls for
- What the building is and how it’s used
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Floors, slabs and movement joints in Millbank
Millbank has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards normally have to keep running, which is why we work a few bays at a time.
For buildings at a park such as Handel Business Centre (1.2 miles south of Millbank), brick and panel movement joints are easy to forget until one leaks. In a school such as Harris Westminster Sixth Form, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Millbank is about 1 mile south-east of City of Westminster, in Greater London. Anywhere in SW1P, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Millbank is one of 764 places we cover in Greater London for movement joints.
We cover the SW1P, W1J and SW1V postcode districts. If your site is on Eaton Lane, Wilton Road and Castle Lane or close by, we can quote for movement joints.

Nearby towns on our patch include Kensington (3 miles west), Shoreditch (3 miles north-east), Walthamstow (8 miles north-east), Hoxton (3 miles north-east), Whitechapel (3 miles north-east) and Hampstead (4 miles north-west).

FAQs: Millbank
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Do you cover business parks and estates near Millbank, such as Handel Business Centre?
Yes, sites like Handel Business Centre are within our area, along with the rest of Millbank. Send details of the unit and the work through our quote form for a quick quote.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Can a joint be sealed if the edges are broken?
The edges have to be sound. If they’re damaged, we’ll say so before any sealing, so the new seal has something to grip.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
After the work
Regular inspection catches problems early. Specifically:
- Put movement joints on the planned maintenance inspection round
- Clear dirt from joint lines during routine cleaning
- Treat a small split as a warning, not a cosmetic issue
- Reopen bays and walkways only after the stated cure time
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Sealing early protects the edges.
How a job runs
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in Millbank can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- 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.
- 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.
Preparing the site
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected
- Make sure the joints can be reached
