Bath resealing in Thomastown, done in place
Baths are resealed with water in them, so the joint opens fully, which stops the new seal tearing the first time the bath is used. Our repair technicians work on shower trays & enclosures, baths and basins & vanity units, and the jobs we see most are damp near the bath and gaps in the seal.
Big or small, you get the same one-year guarantee.

Questions from Thomastown
Is it safe with children and pets around?
Yes, as long as they stay out of the room we are working in. We will tell you when the room can be used again.
Can you reseal over the old silicone?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
Why does the silicone keep cracking?
Something is moving. If it keeps happening, the support may need fixing.
What happens after I send pictures?
We review the photos and send a fixed quote with dates.
Can you quote from pictures?
Yes, almost always. Clear photos let us give you a fixed price without visiting.
Can you redo someone else’s repair?
In most cases. The old repair comes out first.
Do you charge for travel?
Travel is included in the price, with the same prices everywhere we work.
Do I need to be at home?
We need someone to let us in. You don’t need to watch us work.
Prices and what affects them
There are no hourly rates or hidden extras. The price depends on:
- Any earlier repairs that need removing first
- How many items we do on one visit
- The colour and finish to match
- Access to the area
The price reflects the work involved, not where you live. The full price is agreed before you book, with nothing added on the day.
Getting a price from photos
Phone pictures are fine, there is no need for anything special. Just ensure we can see:
- A photo taken from further back
- Something in shot to show the size
- Details of any past repairs
- What it’s made of, if you know
Email us a photo of the damage and one of the entire item, with your CF47 postcode, and we will come back with a fixed quote.

When to call us in Thomastown
A bathroom without good ventilation is hard on sealant: moisture sits on the joints longer, and mould grows faster.
People typically call us when they notice one of these:
- Black mould in the sealant
- Stained silicone
- An untidy old seal
- Missing sealant behind the taps
Questions to ask before you book
- How long it needs to cure
- Whether there are any call-out or travel charges
- Whether they match the colour on site
- How to care for the finish
Landlord and trade work in Thomastown
Builders, developers and site managers book us for snagging repairs, putting right damage done during fitting. We’re CHAS, Constructionline and SafeContractor accredited.
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.
DIY kit or professional repair?
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.
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 the old filler has to come out before a proper repair.
