Bath resealing at your home in Neath
The key to a good reseal is getting all of the old silicone out. Fresh sealant does not stick to old, which is why many DIY jobs peel. Typical jobs include old sealant that looks dirty and unsealed corners, on basins & vanity units, kitchen worktops & sinks and shower trays & enclosures.
The work is guaranteed for twelve months. If there is a problem with the repair within the year, we return and sort it.

Why it’s worth resealing in Neath
Putting new silicone over old does not last. It peels within weeks, and mould stays trapped behind it. A proper reseal removes the old first. Rather than charging by the hour, we price the entire job up front. It depends on the damage, the material and access, and combining items on one visit brings it down.

The process
Your technician turns up when we said we would, introduces themselves and checks the damage against your pictures first. Dust sheets and masking tape go down before we open a single tin. Most visits take about two hours for a bath, and the room is left clean and tidy.
- All the old sealant is cut out and removed.
- The joint is cleaned and any mould treated.
- We ensure the joint is completely dry.
- For a bath, we fill it with water first so the joint is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, taps included.
Before we arrive
- Tell us if there are stairs or a lift
- Ensure the area is dry
- Mention any parking restrictions or tricky access

DIY kit or professional repair?
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
If you are 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.
When a repair isn’t the answer
A repair is not right for every job, including:
- Gaps so wide they need filling or trims before sealing
- Tiles that move, until they’re refixed
- A bath or tray that moves, until its support is fixed
Not sure? Send pictures and we’ll give you a straight answer before you book.
What we work on
- Kitchen worktops & sinks
- Shower trays & enclosures
- Baths
- Basins & vanity units
- Wet rooms
Different materials, different repairs
Shower trays
We put weight on a tray before sealing it, for the same reason.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Work for landlords and builders
For developers and builders, we fix damage before handover, saving last-minute replacements. Several plots can be done in one visit.
Landlords, letting agents and housing providers in Neath use us as well as homeowners. Repairing between tenancies keeps void periods short, and it normally costs far less than a refit.

How to care for the repair
It’s all simple stuff:
- Let steam out after showers
- Ventilate the bathroom well
- Give the seal a regular clean
- Replace the seal when mould sets in
Good ventilation is the best protection, and wipe the joints after use so mould struggles to take hold.
Reseal before water gets in. Gaps or lifting edges mean it needs doing.
