How we handle bath resealing in Tan-y-Bwlch
A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and resealing puts a stop to that. We work on basins & vanity units, shower trays & enclosures and kitchen worktops & sinks, and the jobs we see most are stained silicone and sealant that’s split or lifting.
We guarantee the work for a year. If there’s a problem with the repair within the year, we return and sort it.

What else we do in Tan-y-Bwlch
DIY kit or professional repair?
What a professional repair adds is preparation, colour matching and finishing. 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.
A kit can be fine for a tiny mark out of sight. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.
The process
On the day, we arrive at the time we have agreed, cover the area with dust sheets and masking, and set to work. The job normally takes a couple of hours. We clean up when we are done and tell you when it’s ready to use.
- We cut out and remove all of the old sealant.
- Next we clean the joint and deal with mould.
- 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, taps included.
Before we arrive
- Open a window if you can
- Mention any parking restrictions or tricky access
- Keep a parking space free if you can

Your questions about bath resealing in Tan-y-Bwlch
Do you come to Tan-y-Bwlch?
Yes. We cover the whole UK and travel to Tan-y-Bwlch and the rest of Gwynedd. Send pictures and we’ll quote, or call 0345 017 0787.
Can new silicone go over old?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
Can you redo someone else’s repair?
Yes, we frequently do. It can add a little time, which we include in the quote.
Can I get a quote without a visit?
Yes, almost always. Clear photos let us give you a fixed price without visiting.
Can landlords book you?
Yes. We work for landlords, agents, builders and businesses as well as homeowners.
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 quickly can you book me in?
We’ll give you dates with your quote. Tell us if you need it done quickly.
Will there be a smell?
There may be a mild smell during the work, which fades afterwards.

Honest limits
We will always be straight with you, so here’s what a repair cannot fix:
- Water damage behind the bath that needs a builder
- Tiles that move, until they’re refixed
- A bath or tray that moves, until its support is fixed
Send us pictures and we will tell you honestly before you book.
Surfaces we repair
- Kitchen worktops & sinks
- Wet rooms
- Shower trays & enclosures
- Basins & vanity units
- Baths
How to look after the repair
Looking after the surface is easy:
- Keep bottles off the joints
- Reseal at the first sign of lifting
- Give the seal a regular clean
- Run the extractor fan during and after showers
Let it cure fully before using the bath or shower, usually around 24 hours.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. It may be more than a reseal, and we will say if you need a builder or plumber.
What your bath or shower is made of matters
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.
Shower trays
We put weight on a tray before sealing it, for the same reason.
Do you need bath resealing in Tan-y-Bwlch?
Sealant does not last forever. Every bath or shower adds moisture and soap residue, which mould loves, and the joint moves slightly every time the bath is filled.
You may need us if you’ve spotted:
- A messy previous reseal
- Mould you cannot clean out
- Unsealed corners
- Sealant that is split or lifting
Before you book anyone
- What aftercare is recommended
- What preparation is included
- Whether they match the colour on site
- How changes to the job are handled
