Bath & shower resealing (mastic) in Carmarthenshire
Bath, shower and sink resealing with new mould-resistant silicone in Carmarthenshire, carried out at your home and guaranteed for a year.
- An untidy old seal
- Mould you cannot clean out
- Discoloured, yellow sealant
Can I fix it myself?
It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair won’t last.
How we handle bath resealing in Carmarthenshire
Baths are resealed with water in them, so the joint is at its widest, which stops the new seal tearing the first time the bath is used. Our technicians work on basins & vanity units, kitchen worktops & sinks and shower trays & enclosures, and the jobs we see most are leaks at the edges and gaps by the taps.
All our work comes with our one-year guarantee, wherever you are in Carmarthenshire.

Prices and what affects them
Each job gets its own fixed price. These are the things that affect it:
- How much damage there is
- Any earlier repairs that need removing first
- The type of damage
- Access to the area
The price reflects the work involved, not your postcode. The full price is agreed before booking, with no extras added later.
Getting a price from pictures
You can take the pictures on your phone. Just ensure we can see:
- The material, if you know it
- Your postcode, so we can check dates
- One sharp close-up of the damage
- Any earlier repairs or coatings
Getting a quote takes a couple of minutes: photograph the damage, then the whole bath or shower, include your postcode and send them over. What comes back is a fixed quote, not a guess.
What we can’t put right
Some problems need a builder, plumber or fitter rather than us:
- Hidden water damage
- Gaps so wide they need filling or trims before sealing
- A bath or tray that moves, until its support is fixed
Not sure? Send pictures and we’ll give you a straight answer before booking.

Carmarthenshire: your questions answered
How quickly can you book me in?
Your quote comes with available dates. If it’s urgent, say so and we will do what we can.
Are there extra charges for Carmarthenshire?
We do not add a call-out fee. The fixed quote covers the visit and the work.
Will it make a mess?
Very little mess: we sheet and mask everything nearby, and we take our waste away with us.
Does someone need to be in?
Yes. The technician needs access to the room for the visit, at a time that suits you.
Will the price change on the day?
The price is fixed for what the photos show. Anything extra is discussed before we begin.
What do you need from me?
A close-up, a wider photo and your postcode. Then we’ll agree a date.
Are you accredited?
Yes. Our accreditations include CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.
Can I add another job to the visit?
Of course, and it usually saves money. Send pictures of everything together and we will quote them together.
Aftercare tips
A little care keeps the finish looking good. Our advice:
- Keep bottles off the joints
- Reseal at the first sign of lifting
- Air the room after use
- Run the extractor fan during and after showers
Keep the room well ventilated, and wipe the joints after use so mould struggles to take hold.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, and we’ll say if you need a builder or plumber.
What happens on the day
Once we are through the door, we keep the work contained to the one room. Surfaces nearby are masked off, the work takes about two hours for a bath, depending on what we find, and we finish by cleaning up and talking you through the result.
- We cut out all of the old sealant.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- The bath is filled with water, or weight put on the tray.
- We apply fresh mould-resistant silicone and tool a neat bead.
How to prepare
- Point us to the nearest place to park
- Mention if the room is upstairs or in a flat
- Let the surface dry out before the visit
