Expansion joint sealing for Lower Dicker sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How the job changes by surface

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces priming where the maker calls for it.

How we handle expansion joint sealing in Lower Dicker

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Lower Dicker. We work on cladding panel joints, brickwork movement joints and blockwork control joints, and the usual reasons a site gets in touch are movement joints with split or torn sealant and damp inside where a wall movement joint has failed. Searching for sealant specialists in Lower Dicker? We’ve been sealing commercial buildings since 2005.

Halls, schools and small commercial buildings near places like Lower Dicker have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Traffic, movement and joints around Lower Dicker

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in. At about 45 miles from central London, Lower Dicker is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

For a school such as Hellingly Community Primary School, playground and building joints can be done in the holidays. Across sites such as Swallow Business Park (under half a mile west of Lower Dicker), floor and movement joints can be sealed in phases so units keep working.

Lower Dicker is about 2 miles north-west of Hailsham, in East Sussex. Across the BN27 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our East Sussex coverage takes in 308 places. Brighton is covered too, around 16 miles from Lower Dicker.

If you need expansion joint sealing in BN27, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Quoting for work in Lower Dicker

Before we quote, we look at:

  • Any access equipment needed
  • Joint width, depth and condition
  • Location, for remote and island sites
  • The site’s rules and procedures

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Asbestos survey details if the building is older
  • The site address and postcode
  • A wide shot and a close-up of the area
  • When you need the work done

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. If you have questions first, speak to us on 01277 525 020 or email drawings and photos.

When to bring in a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Your questions answered

Will you take on work at estates like Hackhurst Lane Industrial Estate, close to Lower Dicker?

Yes. We cover Lower Dicker and the area around it, including industrial estates, business parks and retail parks such as Hackhurst Lane Industrial Estate. Photos and a short description are enough for a first look.

Is a hospital such as Amberstone Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can staff carry on working while you are here?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

What’s the difference between an expansion joint and a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and we clear our waste as we work. Smaller jobs around Lower Dicker can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we’ll be in
  • Point out any areas we must not close

Related advice

Do you need expansion joint sealing in Lower Dicker?

Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises. The product has to be suited to the traffic.

Any of the following is a good reason to get the joints checked over:

  • Movement joints with split or torn sealant
  • Sealant peeling off one face of the joint
  • New sealant over old, now failing
  • Water dripping through deck or ramp joints

On industrial estates such as Hackhurst Lane Industrial Estate, less than half a mile to the west of Lower Dicker, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • Is the sealant right for the movement and the substrate?
  • Will failed sealant be removed rather than covered?
  • Proof of insurance
