Bath & shower resealing (mastic) in Gibraltar, Buckinghamshire
Our technicians come to Gibraltar for bath, shower and sink resealing with new mould-resistant silicone. Everything is done in place, with a one-year guarantee.
- Unsealed corners
- Black spots in the silicone
- Water getting behind the bath or tray

What bath resealing costs
We do not charge extra for travel to Gibraltar. The price comes down to:
- The colour and finish to match
- How many items we do on one visit
- The material and finish
- Where the damage is and how we get to it
A repair is priced on what needs doing, not where you live. You’ll see the full price before booking, with no extras added later.
How to get a fixed price
You can usually get a fixed quote without us visiting. To help us price it:
- A wider photo showing the entire bath or shower
- Any earlier repairs or coatings
- One sharp close-up of the damage
- Good light, ideally daylight, without flash glare
Getting a quote takes a couple of minutes: 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.
Bath resealing at your home in Gibraltar
We reseal baths with them filled with water, so the joint is at its widest, which stops the new seal tearing the first time the bath is used. If you are dealing with gaps by the taps and sealant that’s split or lifting, we can help.
A one-year guarantee comes as standard, so you are not left on your own once we have gone.

Common questions in Gibraltar
When can you do it?
Your quote comes with available dates. Tell us if you need it done quickly.
What happens if you find more damage?
We stop, show you and agree any change before carrying on. You will not be charged for anything you haven’t agreed.
Are you a vetted contractor?
Yes. Our accreditations include CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Is there a call-out fee?
We do not add a call-out fee. The fixed quote covers the visit and the work.
Does someone need to be in?
Yes. The technician needs access to the room for the visit, at a time we agree with you.
What do you need from me?
A close-up, a wider photo and your postcode. After that, we just agree a date.
Do you seal over the old sealant?
All the old sealant comes out. Fresh silicone does not stick to old.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
What your bath or shower is made of matters
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Baths
We fill the bath before sealing, to open the joint fully.
Landlords, agents and businesses in Gibraltar
Hotels, guest houses and holiday lets need rooms back in use quickly, so we keep visits short and tidy. We will fit around changeovers where we can.
For anyone letting property in or around Gibraltar, we’ll quote for several properties at once. Just send pictures for each address and we’ll come back with a combined price.
Common problems we fix in Gibraltar
Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning only removes the surface.
You may need us if you’ve spotted:
- An untidy old seal
- Gaps in the seal
- Gaps by the taps
- Stained silicone
Before you book anyone
- How long the guarantee is and what it covers
- How the room is protected while they work
- What aftercare is recommended
- Who will actually do the work
Resealing in Gibraltar: why it matters
Sealing over old silicone is a false economy. It soon peels, and traps mould underneath. We remove the old sealant completely. A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

DIY repairs versus a professional job
Kits are cheap and easy to find, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Doing it properly first is usually the cheaper route.
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
What we do, step by step
We work cleanly and quietly, so you can stay at home while we are there. Protection goes down first, then the job itself takes a couple of hours. At the end we talk you through the curing time and the aftercare.
- We cut out and remove all of the old sealant.
- We clean the joint and treat any mould.
- We dry the joint thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, taps included.
How to prepare
- Clear toiletries, mats and anything else from around the area
- Tell us about any previous repairs or coatings
- Have somewhere for us to park nearby if possible
