How we handle expansion joint sealing in Claygate

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. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. If you are dealing with water getting into the wall through a failed joint and hardened, cracked sealant on exposed facades, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Claygate, preparation and product choice get the time they need.

In and around smaller places like Claygate, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Different surfaces, different methods

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing and flag any joint that seems undersized.

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints or a site visit fills the gaps.

Warehouse floors and decks around Claygate

Claygate is about 33 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors. Rainfall across the South East, Claygate included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

In and around Claygate, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Claygate is about 7 miles south-west of Maidstone, in Kent.

Why act early in Claygate

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Converted and older buildings near places like Claygate tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why appoint us

  • Specification-led, product-correct work
  • A range of standard colours, depending on the product
  • Fixed quotes based on photos, drawings or a visit
  • 12-month guarantee on workmanship

Our process

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a building around Claygate, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  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 tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Ask for a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or send photos by email.

Advice

Common problems we fix in Claygate

Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks.

Site and facilities staff are often the first to spot these:

  • Chipped joint edges on forklift routes
  • Water dripping through deck or ramp joints
  • New sealant over old, now failing
  • Brittle, chalky sealant on external joints

Business parks such as Forstal Business Park (to the north-west of Claygate) have car parks, paved areas and long brick and panel elevations, all with movement joints.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • What level of public liability insurance do they hold?
  • How they handle RAMS and site documents
  • How they’ll work around occupants

Choosing a commercial sealant contractor

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Reopen bays and walkways only after the stated cure time
  • Keep stones and debris out of open joint lines
  • Act on the first tear or lifting edge rather than waiting
  • Keep racking legs and heavy point loads off floor joints

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Claygate: questions and answers

Will you take on work at estates like Forstal Business Park, close to Claygate?

Yes. Estates, retail parks and business parks around Claygate, Forstal Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is Claygate too far out for you?

Not at all. Claygate is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.

Why has the sealant in our expansion joints split?

The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
