What sets the cost

To price the job, we consider:

  • The site’s rules and procedures
  • How much there is to seal
  • Travel to remote or island sites
  • Backing rod, priming and other preparation

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • Any dates the work must fit around
  • How the joints are reached, and at what height
  • Clear photos of the problem areas
  • Rough lengths or quantities, or drawings if you have them

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or send details through our quote form.

Floor joint sealing for commercial buildings in Merton

Concrete floors in warehouses and factories are cut into bays by saw-cut joints and construction joints, and each joint line is a weak edge that wheels run over all day. Our job is to put the right filler or sealant into them for the loads and the movement they see so the edges are held up and debris can’t pack in. We work on construction joints, forklift and pallet-truck routes and joints along racking aisles, and the failures we are asked to look at most are old filler gone hard, cracked or loose and unfilled floor joints collecting dirt and grit. Whoever orders the work in Merton, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Halls, schools and small commercial buildings near places like Merton have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

We sign every job 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.

Common problems we fix in Merton

Soft sealant in a heavily trafficked joint gives the edges little support and the edges fail regardless. The opposite mistake happens as well: a rigid fill in a joint that is still opening cracks or debonds.

Most enquiries start with one or more of the following:

  • Grimy joint lines spoiling a showroom floor
  • Open saw cuts full of debris
  • A rough ride across broken joints
  • Joint edges breaking up under truck wheels

Hospitals like Bicester Community Hospital, 2.9 miles to the north of Merton, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Our contractor checklist

Work for main contractors and building owners

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Merton. Several sites can go on one quote, so there’s one set of paperwork to deal with.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Common questions from Merton clients

Is Merton off your patch?

Not at all. Merton 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 will plan the job to need as few trips as possible.

Is a hospital such as Bicester Community Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you phase floor joint work around operations?

In most cases, just the area being treated is coned off. Each zone reopens when the product can take traffic, then we move to the next.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

What happens if the joint edges are damaged?

Edge condition is recorded when we look at the floor. Damaged edges are flagged up front so the filling isn’t wasted.

What about RAMS and site documents?

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

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Start with the dock areas, where joints fail soonest
  • Ask drivers not to drag forks or pallets
  • Keep grit out of unfilled joints in the meantime
  • Keep photographs of joints that look like they’re failing

Walk the main truck routes every few months and look along the joint lines. Look for separation down one side, new chips in the arris and debris gathering, and photograph anything that changes.

Regular inspection catches failing fills before the edges go. A phased plan, worst routes first, spreads the work out so nothing is left to fail.

What the job involves on each surface

Semi-rigid joint fillers

If a joint is still opening, a semi-rigid filler may part from one face. A later top-up normally puts that right, and we will explain it when we quote.

Loading bays and dock areas

Dock areas see tight turns, heavy loads and weather blowing in. Joints here typically fail first so many programmes begin here.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Merton are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open
  • Send your site hours and access windows
