Expansion joint sealing for commercial buildings in Kings Cross
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors. The enquiries we see most involve car park joints leaking onto vehicles below and brittle, chalky sealant on external joints, across blockwork control joints, cladding panel joints and brickwork movement joints. A single leaking joint is often how a building in Kings Cross first comes to us: we look at the rest while we’re there and tell you what we find.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Kings Cross means thinking about access, loading times and the ULEZ as well as the joints.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use, compared with a full closure. Tell us what has to stay open and we’ll plan around it. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

What the job involves on each surface
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.
Building owners, agents and FMs in Kings Cross
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
When something else is needed
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Movement on a scale no sealant is meant to absorb
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Leaks coming from the membrane rather than the joint seal
If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Cladding panel joints
- Precast concrete panel joints
- Car park decks and ramps
- Podiums and floor movement joints
- Brickwork movement joints
- Blockwork control joints
Questions about Kings Cross
Is Roman Way Industrial Estate, near Kings Cross, within your area?
Yes. Our area takes in Kings Cross and its surroundings, with estates and business parks such as Roman Way Industrial Estate included. A few photos and the unit address let us price the work.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Do you use silicone or polyurethane in movement joints?
Movement capability matters most as set out in BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Yes. Sites across Kings Cross are covered.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next.

- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.

Common problems we fix in Kings Cross
Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way unless width and product are reviewed.
Clients usually get in touch after noticing one or more of the following:
- Water dripping through deck or ramp joints
- Previous reseals laid over old sealant
- Chipped joint edges on forklift routes
- Water getting into the wall through a failed joint
University campuses such as University College London (to the south-west of Kings Cross) have car parks, paved walkways and building elevations with movement joints.
