Bath resealing at your home in Mynydd-Bach
The key to a good reseal is getting all of the old silicone out. New silicone will not bond to old, which is why many DIY jobs peel. We regularly repair basins & vanity units, baths and wet rooms, and the jobs we see most are black mould in the sealant and discoloured, yellow sealant.
Your repair is guaranteed for a year, as with every job we do.

Can I fix it myself?
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. The trouble is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair won’t last.
If you’re set on a kit, follow its instructions closely and work on a clean, dry surface, and give it the full curing time. If it does not work out, we can still repair it properly.

A professional reseal costs little compared with water damage. It’s quick, tidy and protects your home. We don’t add extras on the day. The price we quote from your pictures is the price you pay, unless the damage turns out to be different, in which case we talk to you first.

Aftercare tips
Nothing complicated is needed, just a few sensible habits:
- Air the room after use
- Keep bottles off the joints
- Reseal at the first sign of lifting
- Use the extractor fan
Good ventilation is the best protection, and wipe the joints after use so mould struggles to take hold.
Do not wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.
Prices and what affects them
Each job gets its own fixed price. These are the things that affect it:
- Any earlier repairs that need removing first
- The material and finish
- The type of damage
- The colour and finish to match
A few things move the price: access, material, the extent of the damage and whether we can do several items together. Photos let us give you a fixed figure.
How to get a fixed price
Photographing the damage takes a minute. Please include:
- What it’s made of, if you know
- A wider photo showing the entire bath or shower
- Something in shot to show the size
- One sharp close-up of the damage
Call 0345 017 0787 or use the quote form. With a clear picture of the damage and one of the whole bath or shower, we can give you a fixed price.
FAQs for Mynydd-Bach
Is it safe with children and pets around?
Please keep children and pets out of the room during the visit. The rest of the house is unaffected.
Why does my sealant keep going mouldy?
Usually poor ventilation and moisture sitting on the joint. We use mould-resistant silicone, and ventilation helps it last.

How it works
We turn up at the time we agreed with you, introduces themselves and checks the damage against your pictures first. Dust sheets and masking tape go down before we open a single tin. The work itself takes about two hours for a bath, and the room is left clean and tidy.
- All the old sealant is cut out and removed.
- Next we clean the joint and deal with mould.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, including around the taps.
How to prepare
- Make sure the area is dry
- Have somewhere for us to park nearby if possible
- Have a window or extractor fan available
