Floor joint sealing in Hartley Wintney, done properly

It isn’t only heavy industry. Shops, showrooms and trade counters have joints that take trolleys, foot traffic and scrubber-driers, where a gappy, dirty joint looks untidy and snags castors. A neat, flush fill makes the floor easier to clean and look after. If you are dealing with joint fill separating from the concrete and cracked and crumbling joint fill, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hartley Wintney is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Work in a smaller place like Hartley Wintney is usually one building at a time, so we gather photos and measurements first. Getting widths, depths and traffic details up front means one visit, not two.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email drawings and photos and we’ll come back to it.

Why deal with it now?

While the arrises are intact, filling a joint is straightforward. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled, with longer closures to match. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. What matters most for a job in Hartley Wintney is a clear list of what needs doing. A fixed quote follows.

  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. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close
  • Let us know about inductions and permits

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Related advice

How the quote is worked out

These are the things that shape the price:

  • How much there is to seal
  • Whether old sealant has to be cut out first
  • Distance, for remote addresses
  • Access and working height

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Before you send an enquiry

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

  • Any dates the work must fit around
  • What the building is and how it’s used
  • The site address and postcode
  • The asbestos register, for older buildings

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or use the quote form.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

When to call us in Hartley Wintney

Left open, joints fill with grit, wrap and wood fragments. Packed debris acts like a wedge every time a wheel crosses so the arrises break sooner.

Look out for the following:

  • Unfilled floor joints collecting dirt and grit
  • Filler that has parted from one face
  • Chipped and spalling edges along forklift routes
  • Grimy joint lines spoiling a showroom floor

Phasing is what makes joint work possible on busy sites such as Winkworth Business Park (1.3 miles south-west of Hartley Wintney): one bay, aisle or car park row at a time.

What to look for in a quote

  • Can the work be phased to keep areas open?
  • Health and safety accreditation such as CHAS
  • Whether primer will be used where the manufacturer specifies it
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

What the job involves on each surface

Saw-cut induced joints

Induced joints are sawn into a new slab to control where it cracks. They are narrow but open up as the panels shrink so trafficked runs need a filler that holds the arrises.

Construction joints

Some construction joints have steel edge protection, others are plain concrete. If the edges look unsound, we’ll say so before any filling is done.

Your questions answered

Is Brocketts Business Park, near Hartley Wintney, within your area?

Yes. Estates, retail parks and business parks around Hartley Wintney, Brocketts Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

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

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Do you cover Hartley Wintney?

Yes. Hartley Wintney falls within our area, and you can ring 01277 525 020 or use the quote form to get started.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

Why is there a gap next to the joint filler?

Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. A top-up normally puts it right.

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 external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
