About our remedial sealant in Redhill
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you have sealant applied over old sealant that has lifted and thick, messy sealant smeared over tiles, we can put it right, whatever the surface.
Around Redhill, it’s mostly busy family bathrooms and kitchens, where sealant and grout take a lot of daily wear. The usual signs are mould in the bead, gaps by the sink and grout that is cracked or stained.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

When to call us in Redhill
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Signs it’s time to call us include:
- Kitchen joints letting water behind the worktop
- Caulk or the wrong sealant used in a wet area
- A second bead peeling off the first
- Beads that never stuck properly
Rented homes near Redhill station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

What remedial sealant looks like in Redhill
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For site and facilities teams at buildings such as St Joseph's Catholic Primary 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. For an older house near a landmark such as Saint Matthew's Church, walls and floors in older homes can move, and sealant and grout show it first.

Surface by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. We’ll reseal and tell you if extraction looks to be the issue.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and point out any existing damage.
Why it’s worth doing now in Redhill
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. In Redhill, as anywhere, most leaks start as a small gap in a joint, and early is when they’re cheapest and quickest to sort.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.
