About our bath resealing in Pen-yr-heol
We reseal baths with them filled with water, so the joint is at its widest, so the seal doesn’t tear when the bath is first used. Whether it’s a messy previous reseal and gaps in the seal, we can help, whatever the material.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What bath resealing costs
Prices are worked out job by job. What matters most is:
- How many items we do on one visit
- Any earlier repairs that need removing first
- What the surface is made of
- The size and number of damaged areas
There are no surprise extras on the day. What we quote from your pictures is what you pay, and if the damage turns out to be different, we discuss it before starting.
Quotes from your photos
Photographing the damage takes a minute, and it saves a visit. Please include:
- The material, if you know it
- One picture of the entire bath or shower
- A clear, close picture of the problem area
- Something in shot to show the size
Getting a price is easy: snap the damage close up and then the whole item, send them to us with your postcode, and we’ll reply with a fixed price. Quotes are free and you’re under no obligation.
DIY kit or professional repair?
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
If you are set on a kit, follow its instructions closely, and do not use it until it has fully cured. If it fails, we can still put it right.
When we’d advise against a repair
Some jobs aren’t right for a repair, for example:
- A flexing bath
- Tiles that move, until they’re refixed
- Gaps so wide they need filling or trims before sealing
Not sure? Send photos and we’ll give you a straight answer before you book.
What we work on
- Shower trays & enclosures
- Wet rooms
- Basins & vanity units
- Kitchen worktops & sinks
- Baths
Keeping it looking good
Much of the damage we repair could have been avoided. These habits help:
- Give the seal a regular clean
- Open a window after bathing
- Wipe the joints dry after use
- Ventilate the bathroom well
Leave the sealant to cure for the time we give you, normally about a day.
Don’t wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.

Landlords, agents and businesses in Pen-yr-heol
Builders use us to fix snagging damage before handover. We can visit several plots in one trip to keep costs down.
Rented homes see more wear and tear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.
Materials and what they mean for the repair
Baths
We fill the bath before sealing, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
The process
Nothing needs to be moved out of the room. Everything we use comes in the van with us, put protection down and get going once we have agreed what we’re doing. Most jobs take about two hours for a bath, and you can get on with other things while we are there.
- 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
- Keep pets and children out of the room while we work
- Avoid using the area for a few hours before we arrive
- Clear toiletries, mats and anything else from around the area
Getting a price
Send us pictures of the damage and a wider shot of the entire item, with your CF47 postcode, and we’ll come back with a fixed quote.
