DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Remedial sealant in Warnham
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we will tell you rather than reseal something that will not fix it. We work on shrunken worktop sealant, leaking tray & enclosure joints and mouldy bath & shower sealant, and the jobs we see most are a second bead peeling off the first and a shower that leaks however often it’s resealed.
For a small place like Warnham, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Big or small, you get the same one-year guarantee.

What remedial sealant looks like in Warnham
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Warnham station, botched sealant from a previous quick fix is easier to strip out between tenants. If you look after a building such as Warnham CofE 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.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Deal with small splits early
- Find out why the sealant failed first
- Clean sealant with mild products only
- Look for stains below bathrooms now and then
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
When to call us in Warnham
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
Common reasons people contact us are:
- Dark patches showing through the sealant
- Worktop sealant that has shrunk and split
- Floor or wall movement joints that have failed
- Wide, uneven beads that look worse than the old ones
In the older streets around The Parish Church of St Margaret, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Leave it or put it right?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out. Around Warnham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.
