How we handle bath resealing in St Martin
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 kitchen worktops & sinks, shower trays & enclosures and basins & vanity units, and common reasons people contact us are black spots in the silicone and stained silicone.
You’re covered after we leave: our one-year guarantee applies to every job, and we’ll explain exactly what it covers when we quote.

Your questions about bath resealing in St Martin
Can you redo someone else’s repair?
Yes, regularly. It can add a little time, which we include in the quote.
Do I have to be there?
Yes. The technician needs access to the room for the visit, at a time we agree with you.
Can you do more than one item on the same visit?
Of course, and it typically saves money. Just add the extra items to your photos and you’ll get one combined price.
Can tenants book a repair?
Yes, but check with your landlord or agent first. Landlords are often glad to have it sorted.
Can I get a quote without a visit?
Nearly always. If photos do not show enough, we will ask for another angle.
Why does mould come back so fast?
Damp is the cause. Ventilation and drying keep it clean longer.
What happens once I’ve sent photos?
We come back with a fixed price. You are under no obligation.
Can pets and children be at home?
On the day, the room should be kept clear of pets and children, so the repair isn’t disturbed while it cures.
For landlords and businesses
We also carry out snagging repairs for builders and developers, fixing chips and scratches before handover so nothing needs replacing. We’re CHAS, Constructionline and SafeContractor accredited.
If you manage property in St Martin, we will quote for several properties at once. Just send pictures for each address and we will come back with a combined price.

How it works
Expect a friendly, tidy visit. We agree the arrival time in advance, cover and mask the work area, and get on with the job, which normally takes a couple of hours. If anything looks different from your pictures, we will talk to you before going ahead.
- We cut out and remove all of the old sealant.
- Next we clean the joint and deal with mould.
- We make sure the joint is completely dry.
- For a bath, we fill it with water first so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
Preparing for the visit
- Plan for the room to be out of bounds to pets and children
- Move bottles, mats and clutter away from the area
- Let us know about parking or access
How to get a price
A quote takes minutes to ask for: photograph the damage, then the entire bath or shower, add your postcode and send them to us. What comes back is a fixed price, not a guess.
Advice
DIY repairs versus a professional job
What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.
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 normally cheaper.
What bath resealing costs
We give every job a fixed price from pictures. This is what makes a difference:
- Doing more than one item at once
- The material and finish
- Whether old repairs or coatings need taking off
- Access to the area
We charge the same wherever you are, so there’s no premium for St Martin. What changes the price is the job itself: how much damage, what it’s made of and how many items.
How to get a fixed quote
It only takes a minute to photograph the damage, and it saves a visit. Please include:
- The material, if you know it
- A clear, close picture of the problem area
- The postcode, so we can plan the visit
- Something in shot to show the size
Send us photos of the damage and one of the entire item, with your TR12 postcode, and we’ll come back with a fixed quote.
Keeping it looking good
Simple care helps the repair last. Our advice:
- Clean the joints with a mild cleaner
- Let steam out after showers
- Reseal when black spots won’t clean off
- Run the extractor fan during and after showers
Run the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
Mouldy sealant is more than a cosmetic problem. An early reseal keeps water where it belongs.
Why it’s worth resealing in St Martin
Sealing over old silicone is a false economy. It soon peels, and traps mould underneath. We remove the old sealant completely. The price reflects the work involved, not where you live. You’ll see the full price before booking.

- Sealant that is split or lifting
- Discoloured, yellow sealant
- A messy previous reseal
- Gaps by the taps
What your quote should include
- How to look after the finish
