Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Our process

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For a job in Peacehaven, the main thing is a clear picture of the work. A fixed quote follows.

  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.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  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.

Getting the site ready

  • Let building users know which areas are affected
  • Agree which areas must stay open
  • Send your site hours and access windows

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • A joint that has to be widened or re-detailed before it can work
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

  • Blockwork control joints
  • Podiums and floor movement joints
  • Cladding panel joints
  • Brickwork movement joints
  • Car park decks and ramps
  • Precast concrete panel joints

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Keep racking legs and heavy point loads off floor joints
  • Raise snow-clearing blades over deck joints where possible
  • Leave barriers in place until fresh joint sealant has cured
  • Check joints after long freezing spells

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.

Where floor joints take the most wear near Peacehaven

Peacehaven sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. At about 49 miles from central London, Peacehaven is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.

Phasing is what makes joint work possible on busy sites such as Meridian Shopping Centre (under half a mile west of Peacehaven): one bay, aisle or car park row at a time. Warehouse floors on estates like Meridian Industrial Estate, under half a mile south-west of Peacehaven, carry pallet trucks and forklifts over every saw-cut joint.

Peacehaven is about 5 miles west of Seaford, in East Sussex. Commercial clients in Peacehaven can call on us for movement joints, as part of our coverage of East Sussex.

Do you need expansion joint sealing in Peacehaven?

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.

Typical triggers for a call:

  • Layers of sealant in a movement joint
  • Joints where the bead has lost adhesion
  • Joints packed with grit and debris
  • Torn sealant in brick or block movement joints

University campuses such as University of Brighton (2.7 miles east of Peacehaven) have car parks, paved walkways and building elevations with movement joints.

Questions to ask before you book

  • The named product and why it was chosen
  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards
  • How they handle RAMS and site documents

Our contractor checklist

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Some joints are best left to specialists: for example 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.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Working within restricted access windows
  • How much there is to seal
  • Site requirements such as inductions and permits
  • Any access equipment needed

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Drawings or a marked-up plan, if available
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older
  • Where the site is, with the postcode

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email us.

Peacehaven: questions and answers

Will you take on work at estates like Meridian Industrial Estate, close to Peacehaven?

Yes. Our area takes in Peacehaven and its surroundings, with estates and business parks such as Meridian Industrial Estate included. A few photographs and the unit address let us price the work.

Do you take on work at healthcare sites like Chailey Heritage Marine Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Do you cover Peacehaven?

Yes. We take on work across Peacehaven, with one number for every area we cover.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
