Bath Resealing for Efailnewydd homes
Bath, shower and sink resealing with new mould-resistant silicone at your home in Efailnewydd, with a one-year guarantee on every repair.
- Water getting behind the bath or tray
- A messy previous reseal
- Mould you can’t clean out
Keeping it looking good
To keep it looking its best:
- Replace the seal when mould sets in
- Clean the joints with a mild cleaner
- Store bottles on a shelf
- Dry the seal after bathing
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Do not wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.
How we handle bath resealing in Efailnewydd
A proper reseal starts with removing every trace of the old silicone. New silicone will not bond to old, which is why so many DIY reseals peel. We regularly repair wet rooms, shower trays & enclosures and kitchen worktops & sinks, and the jobs we see most are discoloured, yellow sealant and gaps by the taps.
The work is guaranteed for twelve months. If there’s a problem with the repair within the year, we return and sort it.

Repairs by material
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
We put weight on a tray before sealing it, for the same reason.
Common questions in Efailnewydd
How long will it take?
Normally a couple of hours, then it needs to cure.
How do I stop mould in sealant?
Normally poor ventilation and moisture sitting on the joint. We use mould-resistant silicone, and ventilation helps it last.
How long before I can shower?
Normally about a day later. We confirm before we leave.
Can you repair something that is been repaired before?
Yes, regularly. Removing the old work can add time, and that is in the quote.
When can you do it?
That depends on our diary for your area. We will offer you dates when we send your quote.
What if the damage is worse than the pictures show?
We stop, show you and agree any change before carrying on. Nothing extra is done without your say-so.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Why does the silicone keep cracking?
Generally because the bath or tray moves, or it was sealed with the bath empty. We fill the bath before sealing it.
When to call us in Efailnewydd
A bathroom without good ventilation is hard on sealant: moisture sits on the joints longer, and mould grows faster.
These are the problems we’re asked about most:
- Gaps by the taps
- Damp near the bath
- Sealant that is split or lifting
- A messy previous reseal
What your quote should include
- What the guarantee covers, and for how long
- A fixed quote, and whether VAT is included
- Who will actually do the work
- Whether there are any call-out or travel charges
What we cannot put right
We won’t take on work that will not last, so here’s what a repair can’t put right:
- Loose tiles, which need refixing first
- Gaps so wide they need filling or trims before sealing
- A bath or tray that moves, until its support is fixed
Send us photos and we will tell you honestly.
What we work on
- Wet rooms
- Baths
- Basins & vanity units
- Shower trays & enclosures
- Kitchen worktops & sinks

Can I fix it myself?
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.
Prices and what affects them
We do not charge extra for travel to Efailnewydd. The price depends on:
- How much damage there is
- What the surface is made of
- The colour and finish to match
- Any earlier repairs that need removing first
We charge the same wherever you are, so there is no premium for Efailnewydd. What changes the price is the job itself: how much damage, what it’s made of and how many items.
Getting a price from pictures
A couple of clear pictures is all it takes. Try to include:
- Good light, ideally daylight, without flash glare
- A picture taken from further back
- One sharp close-up of the damage
- Your postcode, so we can check dates
A quote takes minutes to ask for: photograph the damage, then the entire bath or shower, include your postcode and send them to us. What comes back is a fixed price, not a guess.
