Bath resealing in Greenhill, done in place
Preparation is everything in a reseal: every bit of old silicone out, mould treated, the joint clean and dry. Only then does the new sealant go on, in a neat, continuous bead. Typical jobs include black mould in the sealant and gaps in the seal, on shower trays & enclosures, kitchen worktops & sinks and wet rooms.
Whatever the size of the job, you get the same one-year guarantee in Greenhill and across Swansea.

Questions from Greenhill
Will the price change on the day?
We stop, show you and agree any change before carrying on. You will not be charged for anything you haven’t agreed.
What information do you need?
Just photos, your postcode and a contact number. On the day, we only need access to the room.
Are you a vetted contractor?
We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Is there any odour?
Some materials have a smell while they’re applied. It fades as everything cures.
Do you work in Greenhill?
We do. We send a technician to Greenhill for every job, with no extra charge for travel.
Is it worth repairing rather than replacing?
Generally, yes. A repair skips the removal, fitting and redecorating. We’ll be honest if it’s not worth it.
What happens next?
We check the damage, the material and your postcode, then reply with a quote.
Can landlords book you?
Yes, often. We can quote for several properties together and work between tenancies.
Different materials, different repairs
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
When a repair is not the answer
Not everything can be repaired, and we will tell you before we start. We cannot fix:
- Very wide gaps that need a trim
- Hidden water damage
- A bath or tray that moves, until its support is fixed
If in doubt, send pictures and we will say what we think before booking.
Surfaces we repair
- Shower trays & enclosures
- Kitchen worktops & sinks
- Baths
- Wet rooms
- Basins & vanity units
DIY repairs versus a professional job
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and do not use it until it has fully cured. If it doesn’t work out, we can still repair it properly.
If you’ve already tried a DIY fix, that is fine. We take the old repair out and do it properly, so it does not stop a professional repair. It does add a little time, so tell us about it when you send photos.
The process
A typical visit goes like this: we arrive on time, protect everything around the work area, carry out the work and tidy away. Allow around two hours from start to finish. Before leaving, we tell you when it can be used and what to avoid for the first few days.
- We protect the area and mask the joint lines.
- Old sealant and residue are removed.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- The bead is smoothed, the tape removed and the seal left to cure.
How to prepare
- Move bottles, mats and clutter away from the area
- Let us know which floor the room is on
- Point us to the nearest place to park
Getting a price
Pricing is simple: snap the damage close up and then the whole item, send them to us with your postcode, and you will get a fixed quote back. Quotes are free and you are under no obligation.

Signs you need bath resealing in Greenhill
In time, even good sealant discolours, especially in a busy family bathroom. Steam, soap and movement all take their toll.
You may need us if you’ve spotted:
- Water getting behind the bath or tray
- Gaps in the seal
- Silicone smeared on tiles
- Black mould in the sealant

Why it’s worth resealing in Greenhill
Putting new silicone over old doesn’t last. It soon peels, and mould stays trapped behind it. A proper reseal removes the old first. The price reflects the work involved, not where you live. You’ll see the full price before you book, with no extras added later.

How to care for the repair
So the finish stays in good condition for years:
- Give the seal a regular clean
- Open a window after bathing
- Do not stand toiletries on the seal
- Replace the seal when mould sets in
Leave the sealant to cure for the time we give you, normally about a day.
Damp below or loose tiles need checking quickly. It may be more than a reseal, so we’ll tell you if it needs a builder or plumber.
