Bath resealing in Sarn without replacing anything
We reseal baths with them filled with water, so the joint is at its widest, which stops the new seal tearing the first time the bath is used. If you’re dealing with sealant that’s split or lifting and water getting behind the bath or tray, we can help, whatever the material.
Peace of mind is built in: each job carries a one-year guarantee, and we explain what it covers before you book.

Should I try a DIY kit first?
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.
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
Is resealing worth it?
A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Failed sealant can lead to water damage that is much more expensive. The price reflects the work involved, not your postcode. The full price is agreed before you book, with nothing added on the day.

Honest limits

What affects the price in Sarn
We price every job individually. What matters most is:
- Previous DIY repairs that have to come out
- Doing more than one item at once
- The colour and finish to match
- What kind of damage it is
Instead of hourly rates, we price the entire job up front. It depends on the damage, the material and access, and doing several items at once reduces it.
Getting a price from photos
It only takes a minute to photograph the damage, and it saves a visit. Try to send:
- Daylight if possible, and no flash reflection
- Any earlier repairs or coatings
- A picture taken from further back
- Your postcode, so we can check dates
Upload photos of the damage and a wider shot of the entire item, and tell us you are in Sarn, and we’ll come back with a fixed quote.

Different materials, different repairs
Shower trays
Trays are sealed with weight on them, for the same reason.
Baths
We fill the bath before sealing, to open the joint fully.
Work for landlords and builders
We carry out planned and one-off repairs for housing associations and facilities teams. A repair avoids taking out and refitting, which is easier on the people living there.
We work for landlords, letting agents and housing providers in Sarn as well as homeowners. A repair between tenants keeps the property empty for less time, and it costs much less than replacing.
FAQs for Sarn
Can you price it without visiting?
In nearly every case. We only ask to see it in person if the pictures cannot show what we need.
Why does my sealant keep going mouldy?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
Can I add another job to the visit?
Yes. Combining jobs on one visit brings the cost down. Include photos of each item.
Can tenants book a repair?
Yes. Ask your landlord first, and we can send them the quote if that helps.
How long will it take?
Most reseals take about two hours. Leave it to cure before use.
Will the price change on the day?
Your quote covers the damage in the photos. Anything extra is discussed before we begin.
When can I use the bath after resealing?
You’ll get the curing time from us.
Do you hold any accreditations?
Yes. Our accreditations include CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
What we are called out for in Sarn
Most reseals are because of black mould. It grows into the sealant itself, so cleaning only removes the surface.
Typical reasons for a call-out include:
- Silicone coming away from the tiles
- A messy previous reseal
- Gaps by the taps
- Black spots in the silicone
What your quote should include
- Aftercare advice
- What the guarantee covers, and for how long
- Whether the price covers travel
- How soon you can use it again
