Expansion joint sealing for commercial buildings in Shoreham-by-Sea
Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in. Site teams most often ask us about expansion joints split through the centre of the bead and expansion joints filled with dirt and stones, across cladding panel joints, blockwork control joints and podiums and floor movement joints. Looking for mastic applicators who cover Shoreham-by-Sea? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Joints in town car parks and service yards take tyres, de-icing salt and standing water. Catching a joint before its edges break is the simpler route.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Crumbling edges that would give a new bead nothing sound to grip
- Damaged metal nosings or cover plates over a joint
- Leaks coming from the membrane rather than the joint seal
If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer.

General trades versus a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What the job involves on each surface
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, typically low-modulus, with backing rod setting the depth.
On site: what to expect
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. In a town such as Shoreham-by-Sea, most jobs are single buildings. Your photos, drawings or a site visit come first, followed by a fixed quote.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- 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
- Agree which areas must stay open
- Tell staff and tenants when we will be in
- Arrange parking or a loading space

Advice
Common problems we fix in Shoreham-by-Sea
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.
It’s worth sending us details if you spot any of the following:
- Joints where the bead has lost adhesion
- Hardened, cracked sealant on exposed facades
- Expansion joints filled with dirt and stones
- Layers of sealant in a movement joint
Estates like Dolphin Industrial Estate, 0.6 miles to the east of Shoreham-by-Sea, combine warehouse slabs, yards and loading bays, all with joints under wheels.
What your quote should include
- Will CSCS-carded applicators be on site?
- Whether old or failed sealant will be cut out, not overlaid
- How joint depth will be controlled
- Their pre-qualification and accreditations
