How we handle expansion joint sealing in Southwick
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. Most enquiries involve movement joints with split or torn sealant and debris jammed in movement joints, across podiums and floor movement joints, blockwork control joints and car park decks and ramps. A specialist sealant contractor works differently from a general builder: on jobs in Southwick, preparation and product choice get the time they need.
In a smaller place such as Southwick, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Damaged metal nosings or cover plates over a joint
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Joints too narrow for the movement, which need redesigning by the engineer
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.

How a job runs
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically 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 our waste is bagged and taken away as we go. For a job in Southwick, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.

Why deal with it now?
Doing joint resealing alongside other planned works can save on access. But joints already letting water in shouldn’t wait for a programme. We can split the scope into urgent and planned. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
A quote for movement joints depends on quantities, condition and access. Call for a quote.

Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Report split or peeling joint sealant early
- Raise snow-clearing blades over deck joints where possible
- Avoid parking heavy plant or pallets on joint lines
- Note which joints were done, when, and with what
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Phasing around occupants
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
Before you send an enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Clear photos of the problem areas
- Anything awkward about access or site hours
- Whether the building will be occupied during the work
- Where the site is, with the postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
Southwick: questions and answers
Does the sea air around Southwick change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Do you take on work at healthcare sites like Southlands Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you use silicone or polyurethane in movement joints?
The specification comes first, then the joint’s movement and exposure. We name the proposed product in the quote so there are no surprises.
How much does the work cost?
Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or email the details over with a description of the work.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Slabs, ramps and loading bays in Southwick
Southwick lies within about 1 mile of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. At about 46 miles from central London, Southwick is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
Phasing is what makes joint work possible on busy sites such as Dolphin Industrial Estate (1 mile west of Southwick): one bay, aisle or car park row at a time. Retail centres such as Goldstone Retail Park, 2.7 miles to the east of Southwick, have floors, service yards and car parks with joints under constant traffic. For an occupier at a site such as Grange Industrial Estate (0.5 miles south-west of Southwick), the joints at loading doors and dock levellers normally see the hardest wear.
