Bath & shower resealing (mastic) in Gwaelod-y-garth, Cardiff
Bath resealing in Gwaelod-y-garth without the cost of replacing. Send us photos for a fixed price, then book a visit.
- Old sealant that looks dirty
- Missing sealant behind the taps
- Silicone coming away from the tiles
How to care for the repair
Once the work has cured, treat it gently:
- Keep the joints dry
- Let steam out after showers
- Ventilate the bathroom well
- Store bottles on a shelf
Good ventilation is the best protection, and dry the joints after bathing to keep mould away.
Mouldy sealant is more than a cosmetic problem. An early reseal keeps water where it belongs.
Bath resealing at your home in Gwaelod-y-garth
The key to a good reseal is getting all of the old silicone out. Fresh sealant doesn’t stick to old, which is why many DIY jobs peel. We work on basins & vanity units, kitchen worktops & sinks and shower trays & enclosures, and people most often call us about sealant that’s split or lifting and black spots in the silicone.
Whatever the size of the job, it’s backed by a one-year guarantee in Gwaelod-y-garth and across Cardiff.

Gwaelod-y-garth questions
Are there extra charges for Gwaelod-y-garth?
We don’t add a call-out fee. Your fixed price includes everything.
My seal keeps tearing. Why?
Movement is the usual cause. We fill the bath before sealing it.
Is it messy?
We protect the room with dust sheets and masking first, and tidy up before we leave.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are frequently glad to have it sorted.
Can I get a quote without a visit?
Normally, yes. Clear photos let us give you a fixed price without visiting.
How do I get a price for bath resealing in Gwaelod-y-garth?
The exact price depends on the damage, so we quote from pictures. You will get a fixed figure before you book.
It’s been repaired before. Can you still fix it?
Yes, regularly. Removing the old work can add time, and that’s in the quote.
How quickly can you book me in?
We’ll give you dates with your quote. If it’s urgent, say so and we will do what we can.
DIY repairs versus a professional job
You can buy a DIY kit for most repairs, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
What we do, step by step
There’s not much you need to do on the day. Show us the job, point us to the room, and we’ll take it from there. The job generally runs to about two hours for a bath, including clearing up.
- All the old sealant is cut out and removed.
- We clean the joint and treat any mould.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
Before we arrive
- Tell us about any previous repairs or coatings
- Clear toiletries, mats and anything else from around the area
- Keep children and pets away from the room on the day
