Remedial sealant for homes and businesses in Upstreet
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. If you are dealing with black mould underneath the bead and a shower that leaks however often it’s resealed, we can help, on leaking tray & enclosure joints, shrunken worktop sealant and mouldy bath & shower sealant alike.
In a village or hamlet like Upstreet, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
All our work is covered by our 12-month guarantee.

Why act early in Upstreet
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours for a typical bath or shower, longer where several layers have been applied. It’s far less disruption than resealing the same joint again and again. Around Upstreet, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Keep an eye on the ceiling below the bathroom
- Do not add new sealant on top of old
- Keep bleach and abrasives off the bead
- Report a tray that rocks or a worktop that lifts
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
What we can’t put right
We’ll always be straight with you, so here’s what sealant cannot fix:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Tiles that have come away from the wall
- Sealant in an older building that needs testing for asbestos first
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

Remedial sealant around Upstreet
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you live in an older home near Church of St Mary the Virgin, walls and floors in older homes can move, and sealant and grout show it first. Schools such as Chislet Church of England Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Sturry station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
