Bath resealing in Cog, done in place
All of the old sealant is cut out, 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 silicone coming away from the tiles and gaps by the taps, on kitchen worktops & sinks, baths and basins & vanity units.
The work is covered for a year after we finish. Just call us if there’s a problem and we will sort it.

Cog questions
Do you cover the whole of the Vale of Glamorgan?
Everywhere in the UK, Cog included. There’s no extra charge for travel.
Can you repair something that’s been repaired before?
Generally, yes. We remove the old repair before doing a new one.
What happens once I’ve sent photos?
We look at the photos and reply with a fixed price and some dates. If we need another angle, we will ask.
How much does bath resealing cost in Cog?
Every job gets a fixed price from your pictures. Send a close-up of the damage and a wider photo and your postcode.
Are there extra charges for Cog?
There’s no separate call-out charge. Your fixed quote includes everything.
Can new silicone go over old?
All the old sealant comes out. New silicone will not bond to old.
Why does my sealant keep going mouldy?
Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.
Will there be a smell?
Expect a mild smell while we are working, which fades afterwards.
Why it’s worth resealing in Cog
Sealing over old silicone is a false economy. It peels within weeks, and traps mould underneath. A proper reseal removes the old first. A few things move the price: 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.

Common problems we fix in Cog

- Sealant that’s split or lifting

Aftercare tips
To keep it looking its best:
- Give the seal a regular clean
- Run the extractor fan during and after showers
- Do not stand toiletries on the seal
- Wipe the joints dry after use
Keep the room well ventilated, and dry the joints after bathing.
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.
DIY kit or professional repair?
If you are set on a kit, follow its instructions closely, and don’t use it until it has fully cured. If it fails, we can still put it right.
For a hairline mark somewhere you will 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.
