About our bath resealing in Mountain Ash
A reseal is a small job that makes a big difference. Fresh joints make the entire room look cleaner, and they keep water out. Whether it’s old sealant that looks dirty and gaps by the taps, we can typically put it right.
The work is covered for a year after we finish. Just call us if there’s a problem and we will sort it.

DIY repairs versus a professional job
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.
A kit can be fine for a tiny mark out of sight. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.
Materials and what they mean for the repair
Baths
Baths are resealed with water in them, so the joint is at its widest.
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
What we do, step by step
The work is clean and fairly quiet. Protection goes down first, then the work takes a couple of hours. Before we leave, we explain how soon it can be used and how to look after it.
- We cut out and remove all of the old sealant.
- We clean the joint and treat any mould.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, including around the taps.
How to prepare
- Clear toiletries, mats and anything else from around the area
- Tell us about any previous repairs or coatings
- Point us to the nearest place to park
How to get a price

Related advice
Mountain Ash: your questions answered
Do you seal over the old sealant?
We always remove the old sealant completely. New silicone will not bond to old.
What information do you need?
Photos of the damage, a picture of the whole bath or shower and your postcode. Then we will agree a date.
Can you repair several things at once?
Yes. Combining jobs on one visit brings the cost down. Send pictures of everything you’d like done.
What if the damage is worse than the photos show?
Your quote covers the damage in the photos. Anything extra is discussed before we begin.
Is there a guarantee?
Yes: twelve months. If anything goes wrong with the repair within the year, we return to fix it.
Do you cover Mountain Ash?
We do. Repair technicians travel to Mountain Ash from across the region, and the price is the same as everywhere else.
What areas do you cover?
All of Rhondda Cynon Taff, and the rest of the UK. There is no extra charge for travel.
Can you repair something that is been repaired before?
Generally, yes. Let us know what was used before.
How we price bath resealing
A fixed quote means you know the cost before booking. We take into account:
- How easy the damage is to reach
- Whether it’s a chip, crack, burn or wear
- The colour and finish to match
- Any earlier repairs that need removing first
What it costs depends on the type and amount of damage, the material and how many items we do on one visit. We give a fixed quote from your pictures, so there are no surprises on the day.
Getting a price from photos
Phone photos are fine, there is no need for anything special. Ensure they show:
- Any earlier repairs or coatings
- One sharp close-up of the damage
- A coin or ruler next to the damage for scale
- Where you are, by postcode
If you are in Mountain Ash and want a price, the easiest route is pictures: a close-up, a wider shot and your postcode. We reply with a fixed quote and our next available dates.
How to care for the repair
A little care keeps the finish looking good. We recommend:
- Ventilate the bathroom well
- Keep bottles off the joints
- Air the room after use
- Wipe the joints dry after use
Leave the sealant to cure for the time we give you, normally about a day.
Mouldy sealant is more than a cosmetic problem. Resealing early keeps water out of the walls and floor.

- Silicone coming away from the tiles
- Leaks at the edges
- Black mould in the sealant

Is resealing worth it?
A professional reseal costs little compared with water damage. It’s a quick job that protects your walls and floors. No two jobs are quite the same, so each one is priced on its own. The size and type of damage, the material and access all make a difference, and doing several things on one visit costs less than separate visits.
