What we do, step by step
Once we are through the door, the aim is to do the job without disturbing the rest of your home. We mask off everything nearby, the work takes around two hours, depending on what we find, and we finish with a tidy-up and a look at the finished work together.
- All the old sealant is cut out and removed.
- The joint is cleaned and any mould treated.
- We dry the joint thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, taps included.
How to prepare
- Let us know about parking or access
- Mention if the room is upstairs or in a flat
- Have somewhere for us to park nearby if possible

Materials and what they mean for the repair
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
DIY kit or professional repair?
For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair will not last.
Resealing in Gwyddelwern: why it matters
Resealing is routine maintenance. Leaving split or mouldy sealant lets water get behind the bath or tray, which costs far more to put right. It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

Aftercare tips
Looking after the surface is easy, and it makes a real difference:
- Clean the sealant gently and regularly
- Run the extractor fan during and after showers
- Let steam out after showers
- Store bottles on a shelf
Let it cure fully before using the bath or shower, generally around 24 hours.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, so we’ll tell you if it needs a builder or plumber.
How we price bath resealing
Quotes are free and the price is fixed. What we take into account:
- The material
- How hard the colour is to match
- How many items we do on one visit
- How easy the damage is to reach
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 you know the cost before you book.
Quotes from your photos
Phone photos are fine. Just make sure we can see:
- A wider photo showing the entire bath or shower
- A coin beside the damage so we can judge size
- Whether it’s been repaired or coated before
- The postcode, so we can plan the visit
We price from pictures so you don’t have to wait in for a survey. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and we’ll come back with a fixed figure.
