- Very wide gaps that need a trim
- Hidden water damage
If in doubt, send photos and we will say what we think before you book.

Bath resealing in Penberth, done in place
We cut out all of the old sealant, deal with any mould, and apply fresh mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. If you’re dealing with gaps in the seal and mould you can’t clean out, we can normally put it right, whatever the material.
We stand behind the work with a one-year guarantee, so you’re covered after the visit.

What bath resealing costs
We don’t charge extra for travel to Penberth. The price comes down to:
- How easy the damage is to reach
- What kind of damage it is
- How many items we do on one visit
- Previous DIY repairs that have to come out
What it costs depends on how much damage there is and what kind, the material and how many jobs we combine into one visit. We give a fixed price from your pictures, so you know the cost before booking.
How to get a fixed price
Almost every job we do is priced from pictures. This is what we need:
- One sharp close-up of the damage
- What it’s made of, if you know
- The postcode, so we can plan the visit
- A picture taken from further back
Most clients in Penberth get their price from pictures. Tell us what happened and where you are, and we’ll reply with a fixed quote and the earliest dates we have.
What your bath or shower is made of matters
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
Baths
We fill the bath before sealing, so the joint is at its widest.
DIY kit or professional repair?
If you’ve already tried a DIY fix, that is fine. We take the old repair out and do it properly, so it won’t stop us repairing it. It does add a little time, so tell us about it when you send photos.
What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
Why reseal now?
Compared with repairing water damage, resealing is cheap. It’s a quick job that protects your walls and floors. The price reflects the work involved, not your postcode. The full price is agreed before you book, with nothing added on the day.

How it works
Here’s how a visit normally runs: we arrive at the agreed slot, sheet and mask the area around the job, carry out the work and tidy away. Plan for about two hours for a bath from start to finish. Before we go, we will explain when it can be used and how to look after it.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- The joint is cleaned, treated and dried.
- We run a continuous bead of new silicone.
- The bead is smoothed, the tape removed and the seal left to cure.
Before we arrive
- Keep children and pets away from the room on the day
- Let us know if it has been repaired before
- Keep a parking space free if you can
How to get a price
There’s no need for us to visit first. Photos are enough for us to price nearly every job: send a close-up, a wider shot and your postcode, and we will reply with a fixed quote.

Signs you need bath resealing in Penberth
Sealant doesn’t last forever. Each shower leaves moisture and soap behind, which mould feeds on, and the joint moves slightly every time the bath is filled.
These are the problems we’re asked about most:
- Black spots in the silicone
- Silicone smeared on tiles
- Leaks at the edges
- Gaps in the seal
What your quote should include
- Aftercare advice
- How long the guarantee is and what it covers
- How soon you can use it again
- Is the price fixed, and does it include VAT?
For landlords and businesses
For developers and builders, we fix damage before handover. Several plots can be done in one visit.
Housing associations and facilities teams use us for planned and reactive repairs. A repair avoids taking out and refitting, which is easier on the people living there.
