Bath resealing at your home in Cardiff
We seal baths while they’re full of water, so the joint doesn’t tear when the bath is next used. All the old mastic comes out first, since new sealant won’t stick to old silicone. Our technicians work on baths, basins & vanity units and shower trays & enclosures, and people most often call us about black mould in the sealant and messy, uneven old sealant.
Every repair comes with our one-year guarantee. Run the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
What a repair can’t fix
A repair isn’t always the answer, and we’ll tell you before we start. We can’t fix:
- Water damage behind the bath that needs a builder
- Gaps so wide they need filling or trims before sealing
- Loose tiles, which need refixing first
Send us photos and we’ll tell you honestly before you book.

FAQs for Cardiff
Do I need to be at home?
Yes, usually. We need access to the room while we work, and we’ll agree a time with you.
How do I get a price for bath resealing in Cardiff?
Every job gets a fixed price from your photos. Send a close-up and a photo of the whole item and your postcode, and we’ll come back to you with a quote.
When can I use the bath?
Usually around 24 hours, depending on the product. We’ll confirm on the day.
Can new sealant go over the old?
No. New sealant won’t stick to old silicone, and any mould underneath carries on growing, so we remove it all first.
Will you leave a mess?
We protect the room with dust sheets and masking first, and clean up when we finish.
Is it worth repairing rather than replacing?
Usually, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. We’ll tell you honestly if replacement makes more sense.
How soon can I use it again?
Usually the same day or the next, depending on the job. We’ll tell you the curing time before we leave.
Resealing in Cardiff: why it matters
Resealing is routine maintenance. Leaving split or mouldy sealant can let water reach the walls and floor, and that damage costs much more to fix. What it costs depends on how much damage there is and what kind, what it’s made of and how many items we do on one visit. You get a fixed price from your photos, so you know the cost before you book.

How it works
On the day, the technician arrives at the agreed time, protects the room with dust sheets and masking and gets started. The job usually takes around two hours. We tidy up before we leave and tell you when it’s ready to use.
- First we strip out every bit of the old mastic.
- The joint is cleaned and any mould treated.
- We dry the joint thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
How to prepare
- Tell us about parking, stairs or access
- Keep pets and children out of the room while we work
- Mention any earlier repairs or resurfacing
Getting a price
The quickest way to a price is to send a couple of pictures using our quote form or call us. We’ll say straight away whether it can be repaired.
Advice
Do you need bath resealing in Cardiff?
No sealant lasts for ever. Every bath or shower adds moisture and soap residue, which mould loves, and the joint moves slightly every time the bath is filled. Over time it splits, peels or turns black.
Signs it’s time to call us include:
- Black mould in the sealant
- Sealant that has split or peeled
- Gaps letting water behind the bath
- Messy, uneven old sealant
What to look for in a quote
- What aftercare is recommended
- How the room is protected while we work
- How soon you can use it again
- Whether the price is fixed and includes VAT
