Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Why it’s worth doing now in Langton Green

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open, compared with a full closure. We agree phasing with you before work starts. In a smaller place such as Langton Green, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why appoint us

  • Specification-led, product-correct work
  • Colours chosen to suit frames, cladding or finishes where possible
  • 12-month guarantee on workmanship
  • CHAS accredited

Expansion joint sealing in Langton Green, done properly

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, 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 and the bead bonds to the sides, never the back. If you are dealing with weathered movement joint sealant that no longer flexes and joints packed with grit and debris, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Langton Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Work in a smaller place like Langton Green is typically one building at a time. That way the right materials come on the day and the job is done in one visit where possible.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • A joint that has to be widened or re-detailed before it can work
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly before you book.

Surfaces we seal

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

Slabs, ramps and loading bays in Langton Green

Langton Green has two named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment. Rainfall across the South East, Langton Green included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

For a school such as Langton Green Primary School, playground and building joints can be done in the holidays. Office parks like Speldhurst Business Park, 0.9 miles north of Langton Green, have decks, ramps and clad elevations whose joints take movement every day.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically 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. For a site in Langton Green, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Share the asbestos register for older buildings
  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints

Signs you need expansion joint sealing in Langton Green

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

Common reasons buildings call us in:

  • Spalled or broken joint edges in floors and decks
  • Movement joints with split or torn sealant
  • Sealant peeling off one face of the joint
  • Expansion joints filled with dirt and stones

Campuses like Canterbury Christ Church University - Salomons, 1.8 miles north-east of Langton Green, mix old and new buildings, with movement joints wherever they meet.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Health and safety accreditation such as CHAS

How to choose a sealant contractor

What the job involves on each surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it.
