Why reseal now?
Putting new silicone over old doesn’t last. It peels within weeks, and traps mould underneath. A proper reseal removes the old first. The price depends on the type and amount of damage, what it’s made of and how many jobs we combine into one visit. You get a fixed quote from your pictures, so you know the cost before you book.

Your questions about bath resealing in Newtown
Do you cover the entire of Caerphilly?
Across the UK, and that includes Newtown. Our prices are the same everywhere.
It’s been repaired before. Can you still fix it?
Yes, regularly. Removing the old work can add time, and that is in the quote.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Just ensure the landlord agrees.
How do I get a price for bath resealing in Newtown?
We give a fixed quote from your photos. Send a close-up of the damage and a wider photo with your NP11 postcode.
Do I need to be at home?
Yes. The technician needs access to the room for the visit, at a time we agree with you.
How long will it take?
Most reseals take about two hours. It then needs time to cure.
Will the price change on the day?
It’s rare, but if it happens we talk to you first. The price only changes if you agree.
Is there any odour?
There may be a mild smell during the work that clears as it cures.

What bath resealing costs
There’s no area surcharge for Newtown. The price reflects:
- Whether old repairs or coatings need taking off
- Doing more than one item at once
- Whether it’s a chip, crack, burn or wear
- The colour and finish to match
The price reflects the work involved, not where you live. You’ll see the full price before booking, with no extras added later.
Quotes from your photos
Good photos mean an accurate price. Here’s what helps:
- Any earlier repairs or coatings
- A coin or ruler next to the damage for scale
- Any details about the material
- Daylight if possible, and no flash reflection
Getting a quote takes a couple of minutes: take one close-up and one wider shot of the bath or shower, include your postcode and send them to us. You will get a fixed quote, not an estimate.
Aftercare tips
Most damage we see is avoidable. A few tips:
- Keep the joints dry
- Let steam out after showers
- Store bottles on a shelf
- Give the seal a regular clean
Use the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
Mouldy sealant is more than a cosmetic problem. Resealing early keeps water out of the walls and floor.
