Expansion joint sealing for commercial buildings in Lessness Heath
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. We will tell you if the edges need repairing before sealing and phasing can keep areas working. We work on blockwork control joints, brickwork movement joints and cladding panel joints, and the failures we are asked to look at most are weathered movement joint sealant that no longer flexes and expansion joints filled with dirt and stones. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Lessness Heath is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Lessness Heath means thinking about access, loading times and the ULEZ as well as the joints.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after the joints
A few simple habits keep the new joints working:
- Keep traffic off new joints until the cure time is up
- Note which joints were done, when, and with what
- Include every elevation and deck joint in periodic inspections
- Plan racking layouts so feet don’t land on a joint
Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
Our process
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in Lessness Heath 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 start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work

How the job changes by surface
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Do you need expansion joint sealing in Lessness Heath?
Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again, so we check width and movement before quoting.
Things that normally lead to an enquiry:
- Sealant peeling off one face of the joint
- Debris jammed in movement joints
- Spalled or broken joint edges in floors and decks
- Hardened, cracked sealant on exposed facades
Centres like Broadway Shopping Centre (to the south of Lessness Heath) have mall floors and service decks whose joints carry steady traffic.
Before you book anyone
- What level of public liability insurance do they hold?
- How joint depth will be controlled
- The named product and why it was chosen
- Whether primer will be used where the manufacturer specifies it
General trades versus a specialist
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Quoting for work in Lessness Heath
Each job is priced on its own details. The things that drive the figure:
- How accessible the joints are
- Distance, for remote addresses
- The size and state of each joint
- Whether old sealant has to be cut out first
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Clear photographs of the problem areas
- How the joints are reached, and at what height
- The postcode of the building
- What the building is and how it’s used
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email the details over.
