Bath resealing in Llanharan, done in place
Resealing is one of the simplest ways to protect your bathroom. Old, split or mouldy sealant lets water get behind the bath or tray, and resealing puts a stop to that. Whether it’s silicone smeared on tiles and mould you can’t clean out, we can help.
Peace of mind is built in: our one-year guarantee applies to every job, and we explain what it covers before booking.

Llanharan questions
Is it safe with children and pets around?
On the day, the room should be kept clear of pets and children, so the repair isn’t disturbed while it cures.
Will you leave a mess?
No. The work area is masked and covered, and we take our waste away with us.
What happens after I send pictures?
We come back with a fixed price. You are under no obligation.
Is there a call-out fee?
There’s no separate call-out charge. Your fixed price includes everything.
Is the work guaranteed?
Every repair comes with our one-year guarantee. We’ll explain what it covers when we quote.
Can I add another job to the visit?
Yes. Combining jobs on one visit brings the cost down. Send photos of everything you’d like done.
Do you cover the entire of Rhondda Cynon Taff?
We work UK-wide. Prices don’t change with location.
Why does the silicone keep cracking?
Typically because the bath or tray moves, or it was sealed with the bath empty. We fill the bath before sealing it.

The process
Your technician turns up when we said we would, introduces themselves and checks the damage against your pictures first. The floor and nearby surfaces are covered before any work starts. Most visits take about two hours for a bath, and we leave the room as we found it.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
Getting ready for the visit
- Have a window or extractor fan available
- Mention any parking restrictions or tricky access
- Mention if the room is upstairs or in a flat
Getting a price
Getting a quote takes a couple of minutes: take one close-up and one wider shot of the bath or shower, include your postcode and send them over. What comes back is a fixed price, not a guess.

Should I try a DIY kit first?
For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.
It’s natural to want to try a repair 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.
What we’re called out for in Llanharan
Even good sealant eventually discolours. Steam, soap and movement all take their toll.
The things customers typically mention when they call include:
- Silicone smeared on tiles
- Gaps by the taps
- Black spots in the silicone
- Leaks at the edges
Before you book anyone
- How changes to the job are handled
- What aftercare is recommended
- Whether cleaning and preparation are in the price
- Who turns up on the day
Looking after it afterwards
Simple care helps the repair last. We recommend:
- Replace the seal when mould sets in
- Wipe the joints dry after use
- Ventilate the bathroom well
- Don’t stand toiletries on the seal
Keep the room well ventilated, and wipe the joints after use to keep mould away.
Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.
Resealing in Llanharan: why it matters
Sealing over old silicone is a false economy. It soon peels, and mould stays trapped behind it. We remove the old sealant completely. We charge the same wherever you are, so there’s no premium for Llanharan. The job itself decides the price: how much damage, what it’s made of and how many items.

What bath resealing costs
There are no hourly rates or hidden extras. The price is based on:
- Whether it’s a chip, crack, burn or wear
- The size and number of damaged areas
- What the surface is made of
- How easy the damage is to reach
Every job is a little different, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.
How to get a fixed price
Almost every job we do is priced from pictures. This is what to send:
- Details of any past repairs
- The postcode, so we can plan the visit
- A picture taken from further back
- A coin beside the damage so we can judge size
Upload a photo of the damage and a wider shot of the whole item, with your CF72 postcode, and we’ll reply with a fixed price.
Materials and what they mean for the repair
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
When a repair is not the answer
We won’t take on work that will not last, so here’s what a repair cannot put right:
- A bath or tray that moves, until its support is fixed
- Hollow or loose tiles
- Rotten walls or floors behind the bath
If in doubt, send pictures and we’ll say what we think.
