Aftercare tips
Looking after new joints is easy:
- Do not add new sealant on top of old
- Don’t point over movement joints
- Have loose fittings fixed before resealing
- Keep bleach and abrasives off the bead
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.

Why it’s worth doing now in Knockholt Pound
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Knockholt Pound can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What we are called out for in Knockholt Pound
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Most people get in touch after spotting one of these:
- Mould trapped under a layer of silicone
- Sealant that came away because the surface wasn’t prepared
- Sealant applied over old sealant that has lifted
- Smears and lumps from a botched reseal
Homes close to St Katharine's Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
