Questions about Leybourne

Will you take on work at estates like New Hythe Business Park, close to Leybourne?

Yes. Our area takes in Leybourne and its surroundings, with estates and business parks such as New Hythe Business Park included. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is Leybourne too small for you to travel to?

Not at all. Leybourne is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

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.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

About our expansion joint sealing in Leybourne

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in. If you are dealing with previous reseals laid over old sealant and car park joints leaking onto vehicles below, we can help, whatever the surface. Searching for sealant specialists in Leybourne? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For a site near Leybourne, measurements and photos up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Leybourne, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  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. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Share the asbestos register for older buildings
  • Let us know about inductions and permits
  • Make sure the joints can be reached

Related advice

When to call us in Leybourne

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.

Most enquiries start with something like this:

  • Sealant peeling off one face of the joint
  • Joints packed with grit and debris
  • Brittle, chalky sealant on external joints
  • Rain penetration at brick or block movement joints

Hospitals like Maidstone Hospital, 3.1 miles south-east of Leybourne, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Before you book anyone

  • How they handle RAMS and site documents
  • How the existing material will be dealt with
  • Whether primer will be used where the manufacturer specifies it
  • Is the sealant right for the movement and the substrate?

Questions to ask before you appoint anyone

Should maintenance staff do it?

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. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

On a site such as New Hythe Business Park, 1.4 miles to the north-east of Leybourne, the movement joints are in car park slabs, paving and building elevations. In a school such as Lunsford Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What the job involves on each surface

Cladding panel joints

We confirm what access is in place before pricing. Close-up photos help us judge the joints.

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, with primer where specified.

What sets the cost

To price the job, we consider:

  • Joint width, depth and condition
  • Access and working height
  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements

Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
