Bath resealing at your home in Dinas Mawddwy
We cut out all of the old sealant, treat any mould, and reseal with new mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. We’re often asked to fix damp near the bath and mould you can’t clean out, in shower trays & enclosures, wet rooms and basins & vanity units.
Every job is backed for twelve months in Dinas Mawddwy and everywhere else. We return to put right any problem with the work.

Can I fix it myself?
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.
A DIY attempt isn’t a disaster. We remove the old filler and start again, so it doesn’t stop a professional repair. It does add a little time, so tell us about it when you send pictures.
What we do, step by step
A typical visit goes like this: we arrive on time, protect everything around the work area, carry out the work and tidy away. Allow a couple of hours. Before leaving, we tell you how long to leave it and what to avoid for the first few days.
- We cut out and remove all of the old sealant.
- We clean the joint and treat any mould.
- We dry the joint thoroughly.
- For a bath, we fill it with water first so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, taps included.
Getting ready for the visit
- Avoid using the area for a few hours before we arrive
- Mention any earlier repairs or resurfacing
- Tell us if there are stairs or a lift

Is resealing worth it?
Resealing is a small job. Leaving split or mouldy sealant can let water reach the walls and floor, and that damage costs much more to fix. We charge the same wherever you are, so there is no premium for Dinas Mawddwy. What changes the price is the job itself: how much damage, what it’s made of and how many items.

What bath resealing costs
Each job gets its own fixed price. These are the things that affect it:
- The material and finish
- Previous DIY repairs that have to come out
- How easy the damage is to reach
- Doing more than one item at once
Most people are surprised how affordable a repair is, especially compared with replacing and refitting. Send pictures and we will give you the exact figure.
Quotes from your photos
It only takes a minute to photograph the damage. Try to send:
- Daylight if possible, and no flash reflection
- Any earlier repairs or coatings
- A close-up of the damage, in focus
- A coin or ruler next to the damage for scale
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’ll come back to you with a fixed figure.
Repairs by material
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Keeping it looking good
A little care keeps the finish looking good. Our advice:
- Do not stand toiletries on the seal
- Dry the seal after bathing
- Clean the joints with a mild cleaner
- Use the extractor fan
Run the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Reseal before water gets in. Gaps or lifting edges mean it needs doing.
FAQs for Dinas Mawddwy
Why does mould come back so fast?
Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.
Why does my sealant keep splitting?
Movement is the usual cause, or it was sealed with the bath empty. We fill the bath before sealing it.
Is the work guaranteed?
Every repair comes with our one-year guarantee. Ask us what it covers when you get your quote.
Can tenants book a repair?
We can work for tenants, landlords or agents. Just make sure the landlord agrees.
Are there extra charges for Dinas Mawddwy?
We don’t add a call-out fee. Your fixed quote includes everything.
Can I add another job to the visit?
Yes. Combining jobs on one visit brings the cost down. Include photos of each item.
How long does silicone take to cure?
Normally about a day later. We’ll tell you the exact time.
How quickly can you book me in?
It depends on the time of year and where you are. Send photos with your postcode and we’ll reply with the earliest dates.
