DIY kit or professional repair?
If you’ve already tried a DIY fix, that is fine. We take the old repair out and do it properly, so it will not stop us repairing it. It does add a little time, so tell us about it when you send pictures.
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, then guarantee it for a year.
What we are called out for in Llandderfel
In time, even good sealant discolours. Steam, soap and movement all wear it down.
Typical reasons for a call-out include:
- Black mould in the sealant
- An untidy old seal
- Leaks at the edges
- Sealant that’s split or lifting
What to look for in a quote
- How to look after the finish
- A fixed quote, and whether VAT is included
- How changes to the job are handled
- How the colour is matched

Resealing in Llandderfel: why it matters
Putting new silicone over old doesn’t last. It peels within weeks, and traps mould underneath. A proper reseal removes the old first. Instead of hourly rates, we fix the price before we start. Damage, material and access decide it.

Keeping it looking good
Much of the damage we repair could have been avoided. These habits help:
- Use the extractor fan
- Keep bottles off the joints
- Air the room after use
- Clean the joints with a mild cleaner
Use the extractor fan, wipe the joints dry after use, and give them a regular clean 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.
