Materials and what they mean for the repair
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Baths
Baths are resealed with water in them, to open the joint fully.
Why reseal now?
Sealing over old silicone is a false economy. It soon peels, and traps mould underneath. We remove the old sealant completely. A repair usually costs much less than people expect, especially compared with replacing and refitting. Send photos and we’ll give you the exact figure.

Your questions about bath resealing in Fernhill
Do you seal over the old sealant?
Never over old. The old sealant is cut out and the joint cleaned and dried.
Are there extra charges for Fernhill?
No. Our quotes include travel, and we charge the same wherever you are.
Why does my sealant keep splitting?
Generally because the bath or tray moves. We fill the bath before sealing it.
Is there a guarantee?
Yes: twelve months. If there’s a problem with the work in that time, we come back and put it right.
Do you come to Fernhill?
Yes. We cover the whole UK and travel to Fernhill and the rest of Rhondda Cynon Taff. Send pictures and we will quote, or call 0345 017 0787.
Do you hold any accreditations?
Yes. Our accreditations include CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Why does mould come back so fast?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
Is there any odour?
There can be some smell while we work, which is why we ventilate. It fades as everything cures.
Prices and what affects them
Prices are worked out job by job, from your photos. The main factors are:
- Whether we combine several jobs
- Access to the area
- How much damage there is
- The material
Compared with replacing, a repair is generally a fraction of the price, because there’s no removal, plumbing or making good. The quote lists exactly what you’re paying for.
Quotes from your pictures
Most quotes are done from photos alone. To help us price it:
- A coin beside the damage so we can judge size
- The material, if you know it
- A wider photo showing the whole bath or shower
- The postcode, so we can plan the visit
Pricing is simple: snap the damage close up and then the entire item, send them to us with your postcode, and you’ll get a fixed quote back. There’s no charge for the quote and you’re under no obligation.
What happens on the day
On the day itself, there’s little for you to do. Let us in and show us the room, and we’ll get on with it. The job generally runs to around two hours, tidy-up included.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- The bath is filled with water, or weight put on the tray.
- New mould-resistant silicone is applied and tooled neatly.
Preparing for the visit
- Clear toiletries, mats and anything else from around the area
- Avoid using the area for a few hours before we arrive
- Tell us if there are stairs or a lift

Looking after it afterwards
How the surface is treated afterwards matters:
- Open a window after bathing
- Keep bottles off the joints
- Reseal at the first sign of lifting
- Wipe the joints dry after use
Run the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.

Can I fix it myself?
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. The trouble is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.
If you’re set on a kit, follow its instructions closely, make sure the area is clean and completely dry, and don’t use it until it has fully cured. If it doesn’t work out, we can still repair it properly.
