Bath resealing in Cwmcarnhywel, done in place
We cut out all of the old sealant, deal with any mould, and reseal with new mould-resistant silicone. We do this for baths, showers, sinks and worktops, and that includes the awkward spots behind the taps. Our repair technicians work on shower trays & enclosures, wet rooms and basins & vanity units, and the jobs we see most are black mould in the sealant and water getting behind the bath or tray.
Big or small, you get the same one-year guarantee in Cwmcarnhywel and across Carmarthenshire.

What affects the price in Cwmcarnhywel
A fixed quote means you know the cost before you book. We look at:
- Any earlier repairs that need removing first
- How much damage there is
- How easy the damage is to reach
- Unusual colours or finishes
What it costs depends on the type and amount of damage, the material and how many jobs we combine into one visit. You get a fixed price from your pictures, so you know the cost before booking.
Getting a price from photos
A couple of clear pictures is all it takes. It helps if you send:
- One picture of the entire bath or shower
- Good light, ideally daylight, without flash glare
- A coin beside the damage so we can judge size
- Your postcode, so we can check dates
You do not need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed price.

Aftercare tips
Much of the damage we repair could have been avoided. These habits help:
- Use the extractor fan
- Keep bottles off the joints
- Let steam out after showers
- Give the seal a regular clean
Use the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
Black mould in sealant is not just unsightly; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.
FAQs for Cwmcarnhywel
Can landlords book you?
Yes. We work for landlords, agents, builders and businesses as well as householders across Carmarthenshire.
What if the damage is worse than the pictures show?
If we find something the photos didn’t show, we explain it first. The price only changes if you agree.
Are you a vetted contractor?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
Do you cover the entire of Carmarthenshire?

Can you reseal over the old silicone?
We always remove the old sealant completely. Fresh silicone doesn’t stick to old.
It’s been repaired before. Can you still fix it?
In most cases. The old repair comes out first, so mention it when you send pictures.
How soon can you come?
That depends on our diary for your area. Send photos with your postcode and we’ll reply with the earliest dates.
Is it safe with children and pets around?
Just keep them out of the work area. We will tell you when the room can be used again.

Can I fix it myself?
It’s tempting to reach for a kit, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Doing it properly first is typically the cheaper route.
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it does not stop a professional repair. It does add a little time, so tell us about it when you send photos.
Different materials, different repairs
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
Trays are sealed with weight on them, for the same reason.
