How the job changes by surface
Joints between different materials
Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement.
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.
Expansion joint sealing in Southwick, done properly
We have been sealing expansion and movement joints for over 20 years. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. Site teams most often ask us about hardened, cracked sealant on exposed facades and sealant pulling off the joint face, across cladding panel joints, car park decks and ramps and precast concrete panel joints. Facilities teams, main contractors and managing agents in Southwick tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Smaller community and commercial buildings around Southwick have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
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.

Where floor joints take the most wear near Southwick
The sea is no more than about 2 miles from Southwick. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. Southwick is about 62 miles from central London. The roads out of London are lined with trade parks and distribution sheds.
Hospital campuses such as Queen Alexandra Hospital, 2.5 miles to the south-east of Southwick, grow in stages, leaving movement joints wherever new blocks meet old. Estates like Castle Trading Estate (2.1 miles south of Southwick) combine warehouse slabs, yards and loading bays, all with joints under wheels.

- Backing rod, priming and other preparation
- Access and working height
- Working within restricted access windows
- Location, for remote and island sites
Pricing movement joints depends on quantities, condition and access. Ask us for a fixed quote.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Access details, including height
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

What we’re called out for in Southwick
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.
If one of these sounds familiar, it’s time for a closer look:
- Joints where the bead has lost adhesion
- Expansion joints split through the centre of the bead
- Water dripping through deck or ramp joints
- Joints packed with grit and debris
Schools such as King Richard School have movement joints in their walls and floors that are easy to overlook.
What to look for in a quote
- Whether old or failed sealant will be cut out, not overlaid
- What level of public liability insurance do they hold?
- How they’ll work around occupants
- How long is the guarantee, and what does it include?
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Southwick can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- 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.
Getting the site ready
- Let us know about inductions and permits
- Clear stock, furniture or equipment away from the joints
- Confirm the product named in the specification
Getting a fixed quote

Your questions answered
Is Castle Trading Estate, near Southwick, within your area?
Yes. We cover Southwick and the area around it, including industrial estates, business parks and retail parks such as Castle Trading Estate. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Do you take on work at healthcare sites like Queen Alexandra Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. Older rural buildings around Southwick move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
