About our expansion joint sealing in South Street
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you are dealing with layers of sealant in a movement joint and water dripping through deck or ramp joints, we can put it right, on blockwork control joints, cladding panel joints and car park decks and ramps alike. A specialist sealant contractor works differently from a general builder: in South Street, that means joint design, primers and backing rod as standard.
Areas such as a loading bay or car park deck in South Street normally have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Signs you need expansion joint sealing in South Street
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens.
Common reasons buildings call us in:
- New sealant over old, now failing
- Expansion joints split through the centre of the bead
- Water getting into the wall through a failed joint
- Joints packed with grit and debris
Schools like Charles Darwin School often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- How the joint faces will be prepared and primed
- How they handle RAMS and site documents
- Their public liability cover
- Will CSCS-carded applicators be on site?
On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- 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.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000
- Tell us which areas need to stay in use

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint usually costs more than getting it right at the outset, 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.
Why deal with it now?
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex and soon lets go. Full removal and preparation is in every quote. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Damaged metal nosings or cover plates over a joint
- Movement on a scale no sealant is meant to absorb
- Leaks coming from the membrane rather than the joint seal
