Floor joint sealing across Broadstone

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What we’re called out for in Broadstone

Concrete slabs shrink as they dry out, and the saw cuts are there so it cracks in straight, controlled lines. Each panel pulls back as it shrinks and the joints open up so a filler put in early may separate along one side.

Common reasons buildings call us in:

  • Loading bay joints breaking down
  • Flexible sealant torn out by wheels
  • Scruffy, dirty joint lines on a shop or showroom floor
  • Broken arrises where pallet trucks cross

At places like Barradale Farm Industrial Estate (2.9 miles south-west of Broadstone), joints are sealed a section at a time so operations carry on.

Before you book anyone

  • What the guarantee covers, and for how long
  • Their approach to joint depth and backing
  • Whether old or failed sealant will be cut out, not overlaid
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

How we handle floor joint sealing in Broadstone

Few warehouses can shut a whole floor while joints are done, so we phase the work aisle by aisle or bay by bay. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. Most enquiries involve broken arrises where pallet trucks cross and grimy joint lines spoiling a showroom floor, across saw-cut induced joints, joints along racking aisles and loading bays. Whether you call it commercial sealant work, mastic application or joint sealing, in Broadstone it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller community and commercial buildings around Broadstone have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Maintenance after handover

After handover, a little attention goes a long way:

  • Let us know what the floor is cleaned with
  • Treat loading bay joints first if they’re failing
  • Expect fillers on young slabs to need a top-up
  • Record damaged joints with a photo and a location

Problems inside the 12-month guarantee period are ours to put right. Beyond that, an inspection once or twice a year catches failing joints early.

Edges tend to break slowly at first, then quickly. Each chip makes the drop deeper and the next impact harder so early treatment saves a lot of trouble.

Cost factors for floor joints

Before we quote, we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Phasing around occupants
  • Distance, for remote addresses

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Any specification or named product
  • Whether the building will be occupied during the work
  • The site address and postcode
  • When you need the work done

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, speak to us on 01277 525 020 or use the quote form.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a building around Broadstone, 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. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. We tell you when each zone can carry trucks again and move on to the next.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints
  • Flag any permit to work we will need

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

What the job involves on each surface

Saw-cut induced joints

Open saw cuts collect grit and break at the arris. Filled in good time, they stay narrow and neat.

Semi-rigid joint fillers

For trafficked warehouse joints, semi-rigid fillers are common. We place them to depth and trim them level with the slab.

Your questions answered

Can you work at a site such as Roebuck Business Park, by Broadstone?

Yes. Estates, retail parks and business parks around Broadstone, Roebuck Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Is Broadstone too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Do you guarantee industrial floor joints?

There is a 12-month guarantee on our workmanship and the work is covered by public liability insurance.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

How long does a typical visit take?

It depends on the scope, but the work typically takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need. For bigger or phased jobs, we’ll set out a timescale with the quote.
