We travel to Penhelyg for bath, shower and sink resealing with new mould-resistant silicone. Nothing is taken out, and the work is guaranteed.

- Silicone smeared on tiles
Bath resealing in Penhelyg without replacing anything
A proper reseal starts with removing every trace of the old silicone. New silicone won’t bond to old, which is why many DIY jobs peel. If you’re dealing with gaps by the taps and water getting behind the bath or tray, we can generally put it right.
All our work comes with a one-year guarantee.

What else we do in Penhelyg
Materials and what they mean for the repair
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
Shower trays
We put weight on a tray before sealing it, for the same reason.
Can I fix it myself?
A DIY attempt is not a disaster. We remove the old filler and start again, so it doesn’t stop a professional repair. Just mention it when you send pictures, as it can add time.
The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
Why reseal now?
Resealing is routine maintenance. Leaving split or mouldy sealant lets water get behind the bath or tray, and that damage costs much more to fix. Every job is a little different, so we price each one individually. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.

How we price bath resealing
A fixed quote means you know the cost before you book. We take into account:
- What kind of damage it is
- How easy the damage is to reach
- Previous DIY repairs that have to come out
- The material
A repair normally costs much less than people expect, especially compared with replacing and refitting. Send pictures and we will give you the exact figure.
Send photos for a quote
Good photos mean an accurate price. Here’s what we find most useful:
- A wider photo showing the whole bath or shower
- Any earlier repairs or coatings
- Good light, ideally daylight, without flash glare
- A coin or ruler next to the damage for scale
Send us a photo of the damage and a wider shot of the entire item, and tell us you’re in Penhelyg, and we’ll come back with a fixed quote.
How it works
There’s not much you need to do on the day. Show us the job, point us to the room, and we’ll take it from there. Most visits take around two hours, tidy-up included.
- We protect the area and mask the joint lines.
- We remove the old sealant and every trace of residue.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- We smooth the bead, remove the tape and leave it to cure.
How to prepare
- Plan for the room to be out of bounds to pets and children
- Mention any earlier repairs or resurfacing

Advice
Penhelyg questions
How do I book?
Use the quote form or ring 0345 017 0787.
Do you do work for letting agents?
Yes, often. We can quote for several properties together and work between tenancies.
What areas do you cover?
Everywhere in the UK, Penhelyg included. Travel is included in the price.
What does bath resealing cost?
Every job gets a fixed quote from your photos. Send a close-up and a photo of the whole item and your postcode.
How long does a reseal take?
Around two hours for a bath, plus curing time.
Why does my sealant keep going mouldy?
Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.
It’s been repaired before. Can you still fix it?
Yes, we often do. It can add a little time, which we include in the quote.
Why does the silicone keep cracking?
Normally because the bath or tray moves. We seal baths full of water.
Aftercare tips
After the repair has cured, a few habits help it last:
- Air the room after use
- Wipe the joints dry after use
- Run the extractor fan during and after showers
- Store bottles on a shelf
Use the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
Damp below or loose tiles need checking quickly. It may be more than a reseal, and we will say if you need a builder or plumber.
