How we handle floor joint sealing in Twelve Oaks

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. Common call-outs are for cracked grout where a tiled floor needs a movement joint and gaps opening between the floor and skirting, on wet room & bathroom floors, commercial floors and skirting boards.

For a small place like Twelve Oaks, the journey and access are planned in advance, and the work itself is the same as on any site.

There’s a 12-month guarantee on every job, large or small.

Floor joint sealing around Twelve Oaks

Across East Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

If you let a flat or house near Robertsbridge station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. For buildings such as The Parish Church of St Thomas A Becket, floor and skirting joints in halls and kitchens wear like any others.

Why act early in Twelve Oaks

Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. It’s a quick job to seal them now for most homes. Around Twelve Oaks, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Why book with us

  • White, clear, grey or coloured to suit, where the product allows
  • Sealant colour chosen to suit
  • Full insurance on every job
  • Tidy, careful work

How to look after the new joints

To keep the joints looking good and working properly:

  • Keep caulk for dry, still joints only
  • Ask before painting over a sealed joint
  • Use a well-wrung mop rather than flooding the floor
  • Act on grout cracks that run in a straight line

Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead before it has fully cured.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What we do, step by step

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for most rooms, longer for large commercial floors. Somewhere as small as Twelve Oaks, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. The room is cleared along the joints so we can reach them.
  2. We take out the cracked caulk, grout or old sealant.
  3. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied and smooth it.
  5. Finally, we check the work and talk you through aftercare.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Mention any tricky access
  • Clear the area around the work

When it is not the sealant

We will not take on work that will not last, so here’s what sealant can’t put right:

  • Damaged concrete that needs breaking out and repairing
  • Structural movement or subsidence
  • Bouncy or failing floorboards

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

Surfaces we seal

  • Thresholds
  • Commercial floors
  • Concrete floor joints
  • Wet room & bathroom floors

  • Skirting boards

What affects the cost of floor joint sealing

Every job gets its own quote. These are the things that affect it:

  • When we can work, for business premises
  • How many rooms, windows or areas are involved
  • How much old sealant there is and how hard it is to remove
  • The number and length of the joints

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

What we need to know

To make quoting easier, please include:

  • Pictures of the joints, sent by email
  • Whether it’s a home or a business
  • Whether it has been sealed before
  • Where the job is, and your postcode

For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.

Different surfaces, different methods

Thresholds

Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product and tool it flush.

Concrete floor joints

Hard wheels break down the edges of open joints. Sealing them supports the edges and stops debris collecting.
