What happens if it’s left?

Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant moves with the floor and keeps the joint sealed. Where a wall is exposed, as many are in small places like Hertford Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What you get with us

Floor joint sealing in Hertford Heath

Across Hertford Heath, we seal floor and skirting joints in homes and businesses. Each job starts with looking at the floor and the gap, since that decides which sealant suits. We work on wet room & bathroom floors, thresholds and tiled floors, and common reasons people get in touch are cracked grout where a tiled floor needs a movement joint and grout used at the floor edge instead of sealant.

For a small place like Hertford Heath, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

A 12-month guarantee comes as standard, so you are covered after we have gone.

Signs you need floor joint sealing in Hertford Heath

Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away until the joint widens.

The most common problems we see are:

  • Gaps opening between the floor and skirting
  • Failed seals where bathroom floors meet baths and panels
  • Failed joint filler in concrete floors
  • Skirting caulk that keeps splitting

For site and facilities teams at buildings such as Hertford Heath Primary and Nursery School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Aftercare tips

Looking after new joints is easy, and it makes a real difference:

  • Do not slide heavy items over sealed joints
  • Don’t paint over silicone
  • Avoid sloshing water against skirting
  • Keep heavy wheels off new concrete joints until cured

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it while it cures.

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

Can I do it myself?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Do I need to be at home?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

My floor grout keeps cracking in a line. Can you help?

Often, yes, at the edges and along suitable lines. The grout is raked out and replaced with a flexible sealant in a colour to suit, giving the floor room to move.

Do you guarantee your work?

Yes, always. There’s a 12-month guarantee on every job.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Why does the gap under my skirting keep coming back?

Floors shrink and settle, especially in the first year or two and through the heating season. Caulk tends to crack; a flexible sealant doesn’t.
