Need floor joint sealing in Chatham Green?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Honest limits

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Unstable slabs moving under traffic
  • Wide or random cracking that suggests a structural issue
  • Level or flatness problems across the floor

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think.

Where we work in Chatham Green

  • Forklift and pallet-truck routes
  • Retail and showroom floors
  • Construction joints
  • Loading bays
  • Joints along racking aisles
  • Saw-cut induced joints

Looking after the joints

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

  • Start with the dock areas, where joints fail soonest
  • Respect the cure time before traffic returns
  • Keep photos of joints that look like they’re failing
  • Walk the main routes and inspect joint lines on a regular cycle

Young concrete carries on shrinking, so some fillers part slightly from one face. That is common and is typically dealt with by topping up once the slab has settled down.

Regular inspection catches failing fills before the edges go. A phased plan, worst routes first, spreads the work out and keeps on top of the rest.

Doing it in-house

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Common questions from Chatham Green clients

Would you work within a site like Broomfield Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Chatham Green too far out for you?

No. Places such as Chatham Green are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Do you offer coloured sealant?

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

Which is better for warehouse joints, filler or sealant?

There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is typically right, and movement joints or perimeters need something flexible. The quote sets out what goes where.

How soon can traffic go back on the floor?

Each product has its own cure time and cooler floors take longer. We plan the phasing so that waiting time fits your operation.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

How do we get a quote for floor joints?

Send details through our quote form or by email and tell us what runs on the floor. A fixed quote follows with the product and phasing set out.

Common problems we fix in Chatham Green

Joints near dock doors see colder air, rain blown in and water off vehicles on top of the heaviest turning movements. That is usually where joint failure starts.

Most enquiries start with one or more of the following:

  • Chipped and spalling edges along forklift routes
  • Grimy joint lines spoiling a showroom floor
  • Sealant pulled out along a truck route
  • Dock area joints that have failed first

Phasing is what makes joint work possible on busy sites such as Regiment Business Park (2.8 miles south of Chatham Green): one bay, aisle or car park row at a time.

Before you book anyone

  • Their pre-qualification and accreditations
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will RAMS and insurance details be available?
  • What the guarantee covers, and for how long

Choosing a commercial sealant contractor

Owners, agents and contractors

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

From enquiry to sign-off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Smaller jobs around Chatham Green can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  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. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Preparing the site

  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open
