Signs you need remedial sealant in Otterbourne
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Any of these means the joints need attention:
- Wide, uneven beads that look worse than the old ones
- Sealant applied over old sealant that has lifted
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
Homes close to Church of St Matthew include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Your questions about remedial sealant in Otterbourne
Can you help a landlord with a rental near Shawford station?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Do you cover smaller places like Otterbourne?
Yes, Otterbourne is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What if the leak is not the sealant?
You will hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we will not pretend it will.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
How long before the joint can be used?
Cure times vary by product. Before we leave, we will tell you the cure time.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you guarantee remedial jobs?
Yes. Our 12-month guarantee covers the work, and we are ARBOMaster approved.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How the job changes by surface
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal.
When it is not the sealant
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant will not put right:
- Sealant in an older building that needs testing for asbestos first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A bath, tray or worktop that moves until it’s properly fixed
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Where we work in Otterbourne
- Expansion joints
- Shrunken worktop sealant
- Failed movement joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
What happens if it’s left?
Ripping out a bathroom is not normally needed. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you will hear it from us. Where a wall is exposed, as many are in small places like Otterbourne, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
