Floor joint sealing in Dargate

How we handle floor joint sealing in Dargate

Tiled floors can crack along the grout when there’s no room for movement. We can turn a line of grout into a movement joint by replacing it with flexible sealant coloured to suit the grout. We work on concrete floor joints, wet room & bathroom floors and thresholds, and the jobs we see most are floor edges that trap water and grime and gaps between floors and kitchen plinths.

Work in a small place like Dargate just needs the journey and access planning, and once on site, the job is the same as anywhere.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What the job involves on each surface

Concrete floor joints

Old filler, dust and debris are cleaned out of the joint, vacuuming them clean. We fit backing where needed.

Skirting boards

Gaps between skirting and floor open as timber and floors move. A flexible sealant closes the gap without cracking painted or coloured to match.

What happens on the day

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most rooms, longer for large commercial floors. Somewhere as small as Dargate, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. We take out the cracked caulk, grout or old sealant.
  3. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied and smooth it.
  5. We check the joints and explain the aftercare.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • For business premises, tell us about site rules or sign-in
  • Let us know if you’ve seen damp or leaks

Advice

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

How we quote for floor joint sealing

We don’t publish a price list, because no two jobs are the same. What we look at:

  • The number and length of the joints
  • Any mould that needs treating
  • Access and height
  • The type of sealant required

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What we need to know

Before you ask for a quote, have a think about:

  • Roughly how big the job is
  • How we’d reach the joints
  • What’s wrong with the joints now
  • Where the job is, and your postcode

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or send us an email.

Do you need floor joint sealing in Dargate?

Some floors were never given a perimeter gap or movement joint. It pushes against the walls and skirting as it expands.

Signs it’s time to call us include:

  • Chipped and open joints in warehouse floors
  • Worn sealant at door thresholds
  • Skirting that has pulled away from the floor
  • Grout cracking in a straight line across a floor

If you look after a building such as Hernhill Church of England Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Before you book anyone

  • What happens if they find a problem under the old sealant
  • Whether they seal over old material or remove it
  • Which sealant they’ll use, and why
  • Is VAT in the price?

Dargate questions

Is Dargate in your area for floor joint sealing?

Yes, Dargate is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.

Is Dargate within the area you cover?

Yes. Dargate is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you add a movement joint to a tiled floor?

Often, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. Loose or cracked tiles need a tiler first.

How long does floor joint sealing take?

A typical job takes a few hours for most rooms, longer for large commercial floors, including the preparation. We’ll confirm how long when we quote.

Do you remove the old sealant?

Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Floor joint sealing around Dargate

Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.

For buildings such as Church of St Michael, joints in its floors, skirtings and thresholds need resealing as they wear. Rented homes near Selling station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Sweep along the edges of the floor
  • Mark off resealed joints in warehouses
  • Keep caulk for dry, still joints only
  • Look at floor joints each spring

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed.

Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges.
