Baths, trays, basins and kitchen worktops all get resealed using mould-resistant silicone. A typical reseal takes a couple of hours, plus curing time. We are frequently asked to fix silicone smeared on tiles and old sealant that looks dirty, across shower trays & enclosures, baths and kitchen worktops & sinks.
The work is guaranteed for twelve months. If there is a problem with the repair within the year, we return and sort it.

Signs you need bath resealing in Threewaters
Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning only removes the surface.
Most people get in touch when they notice one of these:
- Water getting behind the bath or tray
- Unsealed corners
- Black spots in the silicone
- Sealant that is split or lifting
Questions to ask before you book
- Whether the colour is mixed to match
- Whether a trained technician does the job
- Aftercare advice
- If travel is included in the price
Should I try a DIY kit first?
You can buy a DIY kit for most repairs, and they can make a small mark look better. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair won’t last.
If you’ve already tried a DIY fix, that’s fine. We take the old repair out and do it properly, so it does not stop a professional repair. It does add a little time, so tell us about it when you send photos.
Materials and what they mean for the repair
Baths
Baths are resealed with water in them, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
For landlords and businesses
Builders use us to fix snagging damage before handover. Several plots can be done in one visit.
Builders, developers and site managers book us for snagging repairs, fixing chips and scratches before handover. We’re CHAS, Constructionline and SafeContractor accredited.

What else we do in Threewaters
When a repair isn’t the answer
We will not take on work that won’t last, so here’s what a repair cannot put right:
- Loose tiles, which need refixing first

Threewaters: your questions answered
How do I stop mould in sealant?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
Are there extra charges for Threewaters?
There’s no separate call-out charge. Your fixed quote includes everything.
Will it make a mess?
Dust sheets and masking go down before we start, and tidy up before we leave.
Is a repair better than a new one?
Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.
What areas do you cover?
The entire UK, including all of Cornwall. Send your postcode with your photos and we’ll confirm dates.
What happens after I send photos?
You will get a fixed quote back. There’s no obligation to book.
Why does my sealant keep splitting?
Normally because the bath or tray moves. We seal baths full of water.
Do the materials smell?
It depends on the job, but often a little. Ventilation keeps it to a minimum.
What affects the price in Threewaters
We charge the same across the UK, including Threewaters. The price reflects:
- Unusual colours or finishes
- The material
- Whether it’s a chip, crack, burn or wear
- Access to the area
A repair generally costs much less than people expect, particularly next to the cost of replacement. Send photos and we’ll give you the exact figure.
Send photos for a quote
You can take the pictures on your phone. Just make sure we can see:
- Any details about the material
- A picture taken from further back
- Daylight if possible, and no flash reflection
- Something in shot to show the size
There is no need for us to visit first. Nearly every job can be priced from photos: send a close-up, a wider shot and your postcode, and we’ll reply with a fixed quote.
How to care for the repair
Aftercare is simple, and it makes a real difference:
- Use the extractor fan
- Air the room after use
- Keep the joints dry
- Replace the seal when mould sets in
Leave the sealant to cure for the time we give you, normally about a day.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. It may be more than a reseal, so we will tell you if it needs a builder or plumber.
