Floor joint sealing near Whitstable

What happens if it’s left?

The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Using the wrong one is why many floor joints fail. Around Whitstable, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

Why book with us

  • We never seal over old sealant
  • More than 20 years in sealant work

How we handle floor joint sealing in Whitstable

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out so water and dirt cannot get in. If you’re dealing with caulk that has cracked where the floor moves and rigid edge joints in tiled floors, we can put it right, on concrete floor joints, commercial floors and thresholds alike.

In a town like Whitstable, skirting and floor joints open up as homes settle and floors move with the seasons. Those joints need a flexible sealant, as rigid filler soon cracks out.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints

Joint life depends on how it’s used and looked after. We suggest:

  • Don’t paint over silicone
  • Use furniture pads near skirting
  • Get cracks along tile grout lines looked at early
  • Vacuum floor joints regularly to stop grit building up

Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it while it cures.

Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact.
