Trusted floor joint sealing in Southbourne

The process

We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job normally takes a morning or an afternoon for most homes. In a smaller place like Southbourne, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  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. We apply a flexible sealant suited to the floor.
  5. Finally, we check the work and talk you through aftercare.

Getting ready for the visit

  • Mention any parking rules near the property
  • Let us know if you’ve seen damp or leaks
  • Plan for the work area to be out of bounds to pets and children

Floor joint sealing in Southbourne, done properly

A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors so the joint stays neat. If you have rigid edge joints in tiled floors and worn sealant at door thresholds, we can put it right, on tiled floors, wet room & bathroom floors and skirting boards alike.

In and around Southbourne, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.

The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Looking after it afterwards

Looking after new joints is easy:

  • Sweep along the edges of the floor
  • Keep heavy wheels off new concrete joints until cured
  • Act on grout cracks that run in a straight line
  • Keep floor cleaning water to a minimum at the edges

Do not paint over silicone. If you plan to paint, we will use a paintable product.

Small gaps are quick to seal. Ignored, they fill with dirt and open further and are harder to clean out.

Floor joint sealing in Southbourne: local notes

Floors around West Sussex run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

If you look after a building such as Southbourne Junior School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Rented homes near Southbourne station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies.

Different surfaces, different methods

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking in a colour to suit.

Concrete floor joints

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

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Southbourne questions

Do you cover Southbourne for floor joint sealing?

Yes. We work across London and the South East, and Southbourne is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

Do you work for landlords with property near Southbourne station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.

How long does floor joint sealing take?

Most jobs take a morning or an afternoon for most homes. Your quote will say how long we expect yours to take.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.

Can grout be replaced with sealant on a tiled floor?

In many cases, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.

Is it OK to seal over old sealant?

No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

Signs you need floor joint sealing in Southbourne

A floor laid tight to the walls has no room to move. It pushes against the walls and skirting as it expands, and the sealant or grout breaks.

The problems people usually mention when they call are:

  • Worn sealant at door thresholds
  • Skirting caulk that keeps splitting
  • Perimeter joints in tiled floors filled with grout
  • Gaps opening between the floor and skirting

If you look after a church, hall or community building such as St. John's, joints in its floors, skirtings and thresholds need resealing as they wear.

What your quote should include

  • What happens if they find a problem under the old sealant
  • What product goes in the joint
  • Whether you can choose the colour
  • How the surfaces are prepared before sealing

10 questions to ask before you book

What affects the cost of floor joint sealing

For a quick quote, just ask. What matters most is:

  • How much there is to do
  • Whether old sealant or filler has to be cut out
  • The type of sealant required
  • Whether there’s mould to deal with

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

What to tell us for a quote

To make quoting easier, please include:

  • Where the property is
  • The rough size of the job
  • How we’d reach the joints
  • What the problem is, such as mould, gaps, leaks or cracking

Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

When it isn’t the sealant

Some problems need a builder, plumber or other trade rather than us:

  • Bouncy or failing floorboards
  • Damaged concrete that needs breaking out and repairing
  • Leaks from a failed tanking system

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.
