Why it’s worth resealing in Hirwaun
Resealing costs very little and protects the walls and floor. Failed sealant can lead to water damage that is much more expensive. Compared with replacing, a repair is generally a fraction of the price, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.

Keeping it looking good
Once the work has cured, treat it gently:
- Reseal at the first sign of lifting
- Dry the seal after bathing
- Clean the sealant gently and regularly
- Use the extractor fan
Good ventilation is the best protection, and wipe the joints after use to keep mould away.
Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.

- How much damage there is
- The material
- Previous DIY repairs that have to come out

How to get a fixed quote

Common problems we fix in Hirwaun
Most reseals are because of black mould. It grows into the silicone, so cleaning can’t get it all out.
Look out for any of the following:
- Stained silicone
- Gaps by the taps
- Gaps in the seal
- Water getting behind the bath or tray
Before booking anyone
- How the room is protected while they work
- How soon you can use it again
- Who turns up on the day
- What aftercare is recommended
What happens on the day
Expect a friendly, tidy visit. We agree the arrival time in advance, cover and mask the work area, then carry out the work, which usually takes around two hours. If anything looks different from your photos, we will talk to you before going ahead.
- 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.
- We apply fresh mould-resistant silicone and tool a neat bead.
Getting ready for the visit

Related advice
DIY kit or professional repair?
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.
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.
When we’d advise against a repair
A few problems are outside what a surface repair can do:
- Movement in the bath or tray
- Gaps too big for silicone alone
- Loose tiles, which need refixing first
Send us photos and we will tell you honestly.
Surfaces we repair
- Wet rooms
- Shower trays & enclosures
- Kitchen worktops & sinks
- Baths
- Basins & vanity units
Common questions in Hirwaun
Are you a vetted contractor?
Yes. Our accreditations include CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.
Will it make a mess?
Very little mess: we sheet and mask everything nearby, and we leave the room clean.
Does someone need to be in?
Yes. We need access to the room while we work, at a time that suits you.
Can new silicone go over old?
We always remove the old sealant completely. New silicone will not bond to old.
Is a repair better than a new one?
Generally, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. If replacing would be better, we will say so.
What do you need from me?
A close-up, a wider photo and your postcode. Then we’ll agree a date.
Do the materials smell?
Expect a mild smell while we are working that clears as it cures.
My seal keeps tearing. Why?
Movement is the usual cause, or it was sealed with the bath empty. We fill the bath before sealing it.
