Bath Resealing in Old St Mellons
Local bath resealing for Old St Mellons: photo quotes, tidy work and a year’s guarantee.
- Mould you cannot clean out
- Silicone coming away from the tiles
- An untidy old seal
Why reseal now?
A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.
Why book with us
- Work done at your home or business
- One-year guarantee on every repair
- Honest advice, even when it means no job
- We leave the room as we found it

How we handle bath resealing in Old St Mellons
The key to a good reseal is getting all of the old silicone out. New silicone will not bond to old, which is why many DIY jobs peel. Whether it’s silicone smeared on tiles and unsealed corners, we can help, whatever the material.
A one-year guarantee comes as standard, so you’re not left on your own once we have gone.

Prices and what affects them
Prices are worked out job by job, from your pictures. The main factors are:
- The colour and finish to match
- What the surface is made of
- Access to the area
- Doing more than one item at once
Every job is a little different, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all make a difference, and doing several things on one visit costs less than separate visits.
How to get a fixed quote
Most quotes are done from photos alone. To make it quick:
- Your postcode, so we can check dates
- One picture of the whole bath or shower
- Any details about the material
- Natural light rather than flash
A quote takes minutes to ask for: photograph the damage, then the entire bath or shower, add your postcode and send them to us. What comes back is a fixed price, not a guess.
Old St Mellons questions
Do the materials smell?
There may be a mild smell during the work, which fades afterwards.
It’s been repaired before. Can you still fix it?
Generally, yes. The old repair comes out first, so let us know about it.
How do I stop mould in sealant?
Mould needs moisture. Ventilation and drying keep it clean longer.

We are accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Do you charge for travel?
There is no separate call-out charge. The fixed quote covers the visit and the work.
How long before I can shower?
You’ll get the curing time from us, typically around a day.
How quickly can you book me in?
That depends on our diary for your area. Send photos with your postcode and we’ll reply with the earliest dates.
Do you cover the entire of Cardiff?
All of Cardiff, and the rest of the UK. There is no extra charge for travel.
Common problems we fix in Old St Mellons

Related advice
DIY kit or professional repair?
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, then guarantee it for a year.
For a hairline mark somewhere you’ll never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
Aftercare tips
Once the work has cured, treat it gently:
- Use the extractor fan
- Reseal when black spots will not clean off
- Keep the joints dry
- Clean the joints with a mild cleaner
Use the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
Mouldy sealant is more than a cosmetic problem, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.
Materials and what they mean for the repair
Shower trays
Trays are sealed with weight on them, for the same reason.
Baths
We fill the bath before sealing, so the joint is at its widest.
What a repair cannot fix
We will not take on work that will not last, so these are the limits:
- Loose tiles, which need refixing first
- A bath or tray that moves, until its support is fixed
- Hidden water damage
Send us photos and we will tell you honestly before you book.
Surfaces we repair
- Wet rooms
- Shower trays & enclosures
- Baths
- Basins & vanity units
- Kitchen worktops & sinks
