DIY kit or professional repair?
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.

What bath resealing costs
There are no hourly rates or hidden extras. The price depends on:
- How many items we do on one visit
- Whether old repairs or coatings need taking off
- Where the damage is and how we get to it
- The material
Rather than charging by the hour, we price the whole job up front. Damage, material and access decide it, and combining items on one visit brings it down.
Send photos for a quote
Photographing the damage takes a minute, and it saves a visit. Try to send:
- Any details about the material
- Whether it’s been repaired or coated before
- Daylight if possible, and no flash reflection
- Where you are, by postcode
For most jobs, pictures are all we need to give you a price. Tell us what happened and where you are, and we’ll reply with a fixed quote and the earliest dates we have.

Baths are resealed with water in them, so the joint is at its widest.

We put weight on a tray before sealing it, for the same reason.
Your questions about bath resealing in Tynewydd
Why does my sealant keep going mouldy?
Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.
Will there be a smell?
There may be a mild smell during the work.
When can I use the bath after resealing?
We’ll give you the curing time, generally around a day.
Will you leave a mess?
We protect the room with dust sheets and masking first, and tidy up before we leave.
Is the work guaranteed?
All our work carries our one-year guarantee. Ask us what it covers when you get your quote.
Do you come to Tynewydd?

Is there a call-out fee?
We do not add a call-out fee. The fixed price covers the visit and the work.
Can you reseal over the old silicone?
Never over old. It’s removed, cleaned off and the joint dried first.
