What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Changing the joint layout or spacing of a structure
- Leaks coming from the membrane rather than the joint seal
- Damaged metal nosings or cover plates over a 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.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Other services in North Greenwich
General trades versus a specialist
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.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What the job involves on each surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.
Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Keep product details with the building records for the next reseal
- Put movement joints on the planned maintenance inspection round
- Keep stones and debris out of open joint lines
- Keep scrapers and ploughs from dragging across joint sealant
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. A routine sweep is the simplest protection.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.
From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and we clear our waste as we work. For a job in North Greenwich, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Getting the site ready
- Send any specification or drawings in advance
- Point out any areas we must not close
- Flag any permit to work we’ll need

Common questions from North Greenwich clients
Is hospital work, at somewhere like Blackheath Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you take on jobs in North Greenwich where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
What causes movement joint sealant to fail?
It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
What do you charge?
