For a site near Tunstall, measurements and photos up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

Different surfaces, different methods

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed, and we’ll tell you if any edges need repairing first.

Tunstall: questions and answers

Will you take on work at estates like Kent Science Park, close to Tunstall?

Yes. Estates, retail parks and business parks around Tunstall, Kent Science Park among them, are all within reach. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is Tunstall off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Can a joint be sealed if the edges are broken?

Sound edges are essential. If they’re damaged, we will say so before any sealing, so the new seal has something to grip.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

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 and both need a flexible seal.

What guarantee do you give on joint sealing?

A 12-month guarantee covers our workmanship. Regular sweeping and inspection help the joints last.

Why it’s worth doing now in Tunstall

On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use, compared with a full closure. Tell us what has to stay open and we will plan around it. One visit to deal with every failing joint makes more sense than several trips to a place like Tunstall, rather than one at a time. Photos of every joint help us quote for the whole job.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Keep stones and debris out of open joint lines
  • Look over external and deck joints after a hard winter
  • Raise snow-clearing blades over deck joints where possible
  • Record the sealant used and the date in the O&M file

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.

On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.

Warehouse floors and decks around Tunstall

Central London is about 37 miles from Tunstall. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Tunstall sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

For an estate such as Sittingbourne Memorial Hospital, 1 mile to the north-east of Tunstall, the joints in ramps, decks and long building elevations all need attention over time. In a school such as Tunstall Church of England (Aided) Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Campuses like Canterbury Christ Church University, 4.3 miles to the south-west of Tunstall, mix old and new buildings, with movement joints wherever they meet.

Tunstall is about 1 mile south-west of Sittingbourne, in Kent.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Tunstall, 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 look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000

Cost factors for movement joints

Before we quote, we look at:

  • The product specified
  • How accessible the joints are
  • Travel to remote or island sites
  • Phasing around occupants

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Any specification or named product
  • Whether the building will be occupied during the work
  • The site address and postcode
  • Access details, including height

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email drawings and photos.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
