About our bath resealing in Llanfedw
Preparation is everything in a reseal: every bit of old silicone out, mould treated, the joint clean and dry. Then the fresh sealant goes on, as one neat, continuous bead. We regularly repair baths, shower trays & enclosures and basins & vanity units, and people most frequently call us about silicone coming away from the tiles and a messy previous reseal.
You’re covered for a year from the day of the repair. Just call us if there is a problem and we will come back.

Send us photos and we’ll tell you honestly.

Prices and what affects them
There is no area surcharge for Llanfedw. What changes the price is:
- What the surface is made of
- How hard the colour is to match
- What kind of damage it is
- Any earlier repairs that need removing first
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. We give a fixed quote from your pictures, so there are no surprises on the day.
Send pictures for a quote
Before you send photos, these tips help us give you a firm price:
- Details of any past repairs

What your bath or shower is made of matters
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Looking after it afterwards
It’s all simple stuff:
- Reseal at the first sign of lifting
- Ventilate the bathroom well
- Let steam out after showers
- Keep the joints dry
Leave the sealant to cure for the time we give you, normally about a day.
Mouldy sealant is more than a cosmetic problem. An early reseal keeps water where it belongs.
Common problems we fix in Llanfedw
No sealant lasts for ever. Every bath or shower adds moisture and soap residue, which mould loves, and the joint flexes each time the bath fills.
Customers usually contact us about:
- Black mould in the sealant
- Sealant that is split or lifting
- An untidy old seal
- Old sealant that looks dirty
Before booking anyone
- How soon you can use it again
- How long the guarantee is and what it covers
- Whether a trained technician does the job
- If travel is included in the price
Can I fix it myself?
We understand the appeal of fixing it yourself. The trouble is that kit repairs frequently look fine at first and then fail, and then the old filler has to be removed first.
What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
