How we price bath resealing
We give every job a fixed price from photos. These are the things that affect it:
- What the surface is made of
- How hard the colour is to match
- How much damage there is
- Where the damage is and how we get to it
Rather than charging by the hour, we fix the price before we start. It depends on the damage, the material and access, and combining items on one visit brings it down.
Send pictures for a quote
Most quotes are done from pictures alone. To help us price it:
- A photo taken from further back
- Any details about the material
- Natural light rather than flash
- The postcode, so we can plan the visit
To get a price, send a couple of photos using our quote form or call us. We’ll say immediately if a repair is the right fix.
How we handle bath resealing in Llanerfyl
A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. Our technicians work on baths, wet rooms and basins & vanity units, and the jobs we see most are gaps by the taps and silicone smeared on tiles.
You’re covered after we leave: each job carries a one-year guarantee, and we explain what it covers before you book.

Looking after it afterwards
Aftercare is simple:
- Run the extractor fan during and after showers
- Wipe the joints dry after use
- Give the seal a regular clean
- Do not stand toiletries on the seal
Good ventilation is the best protection, and dry the joints after bathing.
Reseal before water gets in. Gaps or lifting edges mean it needs doing.
Common questions in Llanerfyl
What does bath resealing cost?
We give a fixed price based on pictures of the damage. Send a close-up of the damage and a wider photo and your postcode.
Do you come to Llanerfyl?
Yes, we do. We send a technician to Llanerfyl for every job, and the price is the same as everywhere else.
What happens after I send pictures?
We come back with a fixed quote. You are under no obligation.
Is it messy?
We protect the room with dust sheets and masking first, and tidy up before we leave.
How long will it take?
Most reseals take about two hours. It then needs time to cure.
Why does mould come back so fast?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
What do you need from me?
A close-up, a wider photo and your postcode. Then we’ll agree a date.
Do you charge for travel?
Travel is included in the price, and we charge the same wherever you are.
Common problems we fix in Llanerfyl
Sealant does not last forever. Every bath or shower adds moisture and soap residue, which mould loves, and the joint flexes each time the bath fills.
Get in touch if you’ve noticed:
- Damp near the bath
- Stained silicone
- A messy previous reseal
- Missing sealant behind the taps

- The joint is cleaned and any mould treated.
- We ensure the joint is completely dry.
- We fill a bath with water before sealing so the gap is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, including around the taps.

When we’d advise against a repair
Honesty matters more than a booking, so here’s what a repair cannot fix:
- Very wide gaps that need a trim
- Tiles that move, until they’re refixed
- Movement in the bath or tray
If in doubt, send photos and we’ll say what we think before booking.
What we work on
- Wet rooms
- Baths
- Shower trays & enclosures
- Basins & vanity units
- Kitchen worktops & sinks
For landlords and businesses
We regularly price jobs from inventory or check-out pictures. That means we can quote before you even visit the property, and we liaise with tenants about access if you’d like us to.
Housing associations and facilities teams use us for planned and reactive repairs in Powys and across the UK. A repair avoids taking out and refitting, which matters when someone is living in the home.
What your bath or shower is made of matters
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
