We work cleanly and quietly, so you can carry on at home. We protect the area first, then the work takes about two hours for a bath. At the end we talk you through how soon it can be used and how to care for it.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- We fill the bath, or weight the tray, to open the joint.
- We apply fresh mould-resistant silicone and tool a neat bead.

Advice
Bath resealing at your home in Treharris
The key to a good reseal is getting all of the old silicone out. Fresh sealant does not stick to old, which is why so many DIY reseals peel. We are often asked to fix an untidy old seal and black mould in the sealant, across basins & vanity units, kitchen worktops & sinks and shower trays & enclosures.
Big or small, you get the same one-year guarantee.

Honest limits
Some problems need a builder, plumber or fitter rather than us:
- A bath or tray that moves, until its support is fixed
- Water damage behind the bath that needs a builder
- Tiles that move, until they’re refixed

DIY kit or professional repair?
You can buy a DIY kit for most repairs, and they can make a small mark look better. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is usually cheaper.
Different materials, different repairs
Baths
We fill the bath before sealing, to open the joint fully.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.

What affects the price in Treharris
We give every job a fixed price from photos. This is what makes a difference:
- Where the damage is and how we get to it
- Whether it’s a chip, crack, burn or wear
- Previous DIY repairs that have to come out
- Doing more than one item at once
Set against the cost of replacement, a repair is generally a fraction of the price, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.
Getting a price from photos
Almost every job we do is priced from pictures. This is what to send:
- Where you are, by postcode
- A photo taken from further back
- Any details about the material
- A coin beside the damage so we can judge size
Call 0345 017 0787 or use the quote form. With one close-up and one wider picture, we can price the job without visiting.
How to look after the repair
It’s all simple stuff:
- Clean the joints with a mild cleaner
- Keep the joints dry
- Replace the seal when mould sets in
- Open a window after bathing
Avoid scraping the joints, and do not stand bottles on the seal.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
Common problems we fix in Treharris
Poor ventilation speeds things up: moisture sits on the joints longer, and mould takes hold.
Customers generally contact us about:
- Silicone coming away from the tiles
- Black mould in the sealant
- Damp near the bath
- Silicone smeared on tiles
Questions to ask before booking
- If travel is included in the price
- How long it needs to cure
