Floor joint sealing near Whitesmith

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How the job changes by surface

Isolation joints at walls and columns

We plan column and wall joints around racking and fixed plant.

Retail and showroom floors

In retail, joints take trolleys, castors and cleaning machines rather than forklifts. The product is chosen for that traffic and the appearance is part of the brief.

How we handle floor joint sealing in Whitesmith

Forklifts and pallet trucks are hard on open joints. Each crossing knocks the unsupported edge until a crisp saw cut becomes a wide, broken groove. Filling the joint properly gives the edges back their support, which is kinder to trucks, loads and operators. If you are dealing with joint edges breaking up under truck wheels and untidy open joints in a retail unit, we can help, whatever the surface. Whoever orders the work in Whitesmith, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Whitesmith, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

How the quote is worked out

What shapes the price:

  • Working within restricted access windows
  • Backing rod, priming and other preparation
  • How much there is to seal
  • Removal of failed or old sealant

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • Any specification or named product
  • Whether the building will be occupied during the work
  • Clear photographs of the problem areas
  • When you need the work done

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email drawings and photos with what you know.

Keeping the joints sound

For the best life from the joints:

  • Remind operators to lift rather than drag
  • Tell us about strong cleaning chemicals before we quote
  • Plan for a top-up on newer floors
  • Photograph any joint that starts to chip

Young concrete carries on shrinking, so some fillers part slightly from one face. It is a known trait of new floors and a later top-up deals with it in most cases.

A broken joint on a main route is crossed by every truck on that route. Sorting it early looks after your equipment as well as the slab.

Slabs, ramps and loading bays in Whitesmith

At about 43 miles from central London, Whitesmith is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors. Rainfall across the South East, Whitesmith included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.

Business parks such as Stone Cross Business Centre, 1.2 miles south-west of Whitesmith, have car parks, paved areas and long brick and panel elevations, all with movement joints. In a school such as Chiddingly Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Large sites such as Hellingly Hospital Railway, 4 miles east of Whitesmith, have car parks, service roads and long elevations with movement joints in brick and panels.

Whitesmith is about 5 miles north-west of Hailsham, in East Sussex. Commercial clients in Whitesmith can call on us for floor joints, as part of our coverage of East Sussex.

Questions about Whitesmith

Is Whitesmith too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you take on a job at a hospital such as Hellingly Hospital Railway?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

When can forklifts run over new joint filler?

The wait is set by the product’s cure time, and cold floors slow it down. We plan the phasing so that waiting time fits your operation.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

How do we get a quote for floor joints?

Approximate metres of joint, photos of typical and worst areas, and a floor plan are normally enough for a quick quote. For larger floors, a site visit is often best so call 01277 525 020 or email us to set one up.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Whitesmith, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. The area is handed back once it has cured enough to take traffic.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits
  • Agree which areas must stay open

Request a quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Advice

Building owners, agents and FMs in Whitesmith

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Redoing a failed joint normally 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.
