Bath resealing in St David's, done in place
A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and resealing puts a stop to that. Typical jobs include discoloured, yellow sealant and sealant that’s split or lifting, across wet rooms, basins & vanity units and kitchen worktops & sinks.
Your repair is guaranteed for a year, as with every job we do.

St David's questions
Is there any odour?
There may be a mild smell during the work that clears as it cures.
Why does the silicone keep cracking?
Movement is the usual cause, or it was sealed with the bath empty. We fill the bath before sealing it.
How long before I can shower?
Usually after around 24 hours. We will tell you the exact time.
What happens if you find more damage?
We will show you and explain before doing anything extra. You will not be charged for anything you haven’t agreed.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Is it safe with children and pets around?
Please keep children and pets out of the room during the visit. Everywhere else in the home is fine.
Do I have to be there?
Yes. We need access to the room while we work, at a time we agree with you.
Can landlords book you?
Yes, often. We can quote for several properties together and work between tenancies.
Keeping it looking good
After the repair has cured, a few habits help it last:
- Wipe the joints dry after use
- Reseal when black spots won’t clean off
- Run the extractor fan during and after showers
- Air the room after use
Keep the room well ventilated, and dry the joints after bathing.
Black mould in sealant isn’t just unsightly. An early reseal keeps water where it belongs.
Should I try a DIY kit 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 frequently lifts.
A DIY attempt isn’t a disaster. We remove the old filler and start again, so it does not stop a professional repair. It does add a little time, so tell us about it when you send pictures.
What we do, step by step
A typical visit goes like this: we arrive at the agreed slot, protect everything around the work area, do the job and clear up. Allow about two hours for a bath. Before we go, we’ll explain how long to leave it and what to avoid for the first few days.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- We smooth the bead, remove the tape and leave it to cure.
Preparing for the visit
- Avoid using the area for a few hours before we arrive
- Have a window or extractor fan available
- Have somewhere for us to park nearby if possible

Letting agents frequently send us pictures straight from the inventory. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.
We are used to working with agents and managing companies. Send the address, pictures and access details and we’ll arrange it.

Different materials, different repairs
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Do you need bath resealing in St David's?
A bathroom without good ventilation is hard on sealant: damp hangs around, and mould takes hold.
You may need us if you’ve spotted any of these:
- Unsealed corners
- A messy previous reseal
- Gaps in the seal
- Black spots in the silicone
