About our bath resealing in Llanberis
We reseal baths with them filled with water, so the joint opens fully, which stops the new seal tearing the first time the bath is used. Our repair technicians work on basins & vanity units, wet rooms and baths, and people most often call us about black spots in the silicone and an untidy old seal.
All our work is covered by our one-year guarantee, wherever you are in Gwynedd.

Keeping it looking good
Good habits make a big difference to how long a repair lasts:
- Don’t stand toiletries on the seal
- Dry the seal after bathing
- Reseal at the first sign of lifting
- Run the extractor fan during and after showers
Use the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. An early reseal keeps water where it belongs.
How we price bath resealing
There are no hourly rates or hidden extras. The price depends on:
- How many items we do on one visit
- The material and finish
- Any earlier repairs that need removing first
- How many areas need work
A repair generally costs much less than people expect, particularly next to the cost of replacement. Photos let us give you the exact figure.
Send photos for a quote
You can take the photos on your phone, there’s no need for anything special. Make sure they show:
- Any details about the material
- A picture taken from further back
- Natural light rather than flash
- The postcode, so we can plan the visit
We price from photos so you do not have to wait in for a survey. Use the quote form, or ring 0345 017 0787 to talk it through, and we’ll come back with a fixed figure.

Should I try a DIY kit first?
DIY kits are sold for most surfaces, and they can make a small mark look better. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it doesn’t stop a professional repair. Just mention it when you send photos, as it can add time.
Why it’s worth resealing in Llanberis
A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. 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. Send photos and you will get a fixed figure.

Common questions in Llanberis
Do I need to be at home?
Yes. The technician needs access to the room for the visit, at a time we agree with you.
How do I book?
Just photos, your postcode and a contact number. On the day, access to the room.
Do you work in Llanberis?
Yes. We cover the whole UK and come to Llanberis. Send photos and we’ll quote, or call 0345 017 0787.
How long will it take?
Around two hours for a bath, then it needs to cure.
Is my repair covered?
All our work carries our one-year guarantee. We will explain what it covers when we quote.
Is a repair better than a new one?
Generally, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. If replacing would be better, we’ll say so.
Is it OK to have pets in the house?
We ask you to keep children and pets out of the room while we work and until it has cured. The rest of the house is unaffected.
Can you repair something that’s been repaired before?
Most of the time. Tell us what was done before and we will plan for it.
