If you have kitchen joints letting water behind the worktop and products that weren’t meant for the joint, we can put it right, whatever the surface.

Remedial sealant around John's Cross
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

If you look after a building such as Vinehall School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

What sealant work can’t fix
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Older mastics that may need an asbestos check before removal
- Cracks in the fitting rather than the joint
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.
What we seal
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Failed movement joints
- Botched or over-sealed joints
- Expansion joints
- Mouldy bath & shower sealant
Surface by surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed.
When to call us in John's Cross
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
The most common problems we see are:
- Kitchen joints letting water behind the worktop
- Beads that never stuck properly
- Over-sealed joints coming away
- Smears and lumps from a botched reseal
Rented homes near Robertsbridge station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why act early in John's Cross

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Report a tray that rocks or a worktop that lifts
- Clean sealant with mild products only
- Ask why a joint failed before redoing it
- Don’t wait for a small gap to become a leak
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
