Materials and what they mean for the repair
Shower trays
We put weight on a tray before sealing it, for the same reason.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Keeping it looking good
After the repair has cured, a few habits help it last:
- Clean the sealant gently and regularly
- Let steam out after showers
- Wipe the joints dry after use
- Reseal at the first sign of lifting
Good ventilation is the best protection, and wipe the joints after use.
Reseal before water gets in. Gaps or lifting edges mean it needs doing.

Your questions about bath resealing in Llansadwrn
Is it OK to have pets in the house?
Yes, as long as they stay out of the room we’re working in. We will let you know when it’s safe to use again.
Will there be a smell?
Some materials have a smell while they’re applied, which is why we ventilate. It fades as everything cures.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
What happens next?
You’ll get a fixed quote back. There’s no obligation to book.
Why does my sealant keep splitting?
Generally because the bath or tray moves, or it was sealed with the bath empty. We seal baths full of water.
Can new silicone go over old?
We always remove the old sealant completely. Fresh silicone doesn’t stick to old.
Can you repair something that is been repaired before?
Most of the time. Tell us what was done before and we’ll plan for it.
When can you do it?
It depends on the time of year and where you are. We’ll offer you dates when we send your quote.
Honest limits
We would rather lose a job than do one that won’t last, so these are the limits:
- A flexing bath
- Hidden water damage
- Gaps so wide they need filling or trims before sealing
If in doubt, send photos and we’ll say what we think before booking.

Advice
Should I try a DIY kit first?
Kits are cheap and easy to find, but the repairs we redo most often are DIY ones that have discoloured or lifted. Getting it right first time is typically cheaper.
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and give it the full curing time. If it doesn’t work out, we can still repair it properly.
Is resealing worth it?
Sealing over old silicone is a false economy. It soon peels, and mould stays trapped behind it. We remove the old sealant completely. Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send pictures and we will give you the exact figure.
