About our bath resealing in Rhostrehwfa
Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, as one neat, continuous bead. We work on baths, basins & vanity units and kitchen worktops & sinks, and the jobs we see most are black spots in the silicone and sealant that’s split or lifting.

DIY repairs versus a professional job
Kits are cheap and easy to find, but the repairs we redo most often are DIY ones that have discoloured or lifted. Doing it properly first is generally the cheaper route.
DIY kits are sold for most surfaces, and they can make a small mark look better. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.

Different materials, different repairs
Shower trays
Trays are sealed with weight on them, for the same reason.
Baths
Baths are resealed with water in them, to open the joint fully.
Aftercare tips
Once the work has cured, treat it gently:
- Use the extractor fan
- Keep bottles off the joints
- Clean the joints with a mild cleaner
- Open a window after bathing
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.
For landlords and businesses
Rental properties take more wear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.
Housing associations and facilities teams use us for planned and reactive repairs in Isle of Anglesey and across the UK. A repair avoids taking out and refitting, which is easier on the people living there.
FAQs for Rhostrehwfa
Do the materials smell?
There can be some smell while we work. It clears as the materials cure.

In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.
How quickly can you book me in?
We’ll give you dates with your quote. Tell us if you need it done quickly.
Do you come to Rhostrehwfa?
Yes. We work across the UK and come to Rhostrehwfa and the rest of Isle of Anglesey. Send photos and we’ll quote, or call 0345 017 0787.

There is no separate call-out charge. Your fixed price includes everything.
It’s been repaired before. Can you still fix it?
Most of the time. Let us know what was used before.
How long does a reseal take?
Around two hours for a bath, then it needs to cure.
Why does my sealant keep splitting?
Movement is the usual cause, or it was sealed with the bath empty. We fill the bath before sealing it.
