About our bath resealing in Dinas
We cut out all of the old sealant, treat any mould, and apply fresh mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. We are frequently asked to fix gaps by the taps and black spots in the silicone, across kitchen worktops & sinks, shower trays & enclosures and wet rooms.
Peace of mind is built in: each job carries a one-year guarantee, and we explain what it covers before you book.

What affects the price in Dinas
We price every job individually, from your pictures. The main factors are:
- How easy the damage is to reach
- Doing more than one item at once
- How hard the colour is to match
- The size and number of damaged areas
Our prices are the same across the UK, so there is no premium for Dinas. What changes the price is the job itself: the material, the amount of damage and how many items.
Getting a price from pictures
You can take the pictures on your phone, there is no need for anything special. Make sure they show:
- The material, if you know it
- The postcode, so we can plan the visit
- Details of any past repairs
- A coin beside the damage so we can judge size
Ring 0345 017 0787, or send us photos through the quote form. With one close-up and one wider picture, we can price the job the same day in most cases.

How the visit works
From the moment we arrive, the aim is to do the job without disturbing the rest of your home. Surfaces nearby are masked off, the job takes about two hours for a bath, depending on what we find, and we finish with a tidy-up and a look at the finished work together.
- We cut out and remove all of the old sealant.
- We clean the joint and treat any mould.
- We make sure the joint is completely dry.
- 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.
Getting ready for the visit

- Keep pets and children out of the room while we work
- Ensure the room can be ventilated

Aftercare tips
After the repair has cured, a few habits help it last:
- Open a window after bathing
- Ventilate the bathroom well
- Reseal at the first sign of lifting
- Give the seal a regular clean
Let it cure fully before using the bath or shower, generally around 24 hours.
Damp below or loose tiles need checking quickly. There may be more going on, and we will say if you need a builder or plumber.
DIY kit or professional repair?
If you’re set on a kit, follow its instructions closely and work on a clean, dry surface, and give it the full curing time. If it does not work out, we can still repair it properly.
What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
Signs you need bath resealing in Dinas
No sealant lasts for ever. Every bath or shower adds moisture and soap residue, which mould feeds on, and the joint moves slightly every time the bath is filled.
Keep an eye out for these signs:
- Mould you can’t clean out
- Gaps by the taps
- Stained silicone
- Gaps in the seal
Before you book anyone
- What happens if the damage is worse than the pictures show
- Whether a trained technician does the job
- Whether cleaning and preparation are in the price
- How your room will be protected

Dinas questions
How long does resealing take?
A bath or shower generally takes a couple of hours. It then needs time to cure.
Can you do more than one item on the same visit?
Yes. Doing several items on one visit generally costs less than separate visits. Send photos of everything you’d like done.
Is my repair covered?
Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.
Do the materials smell?
Some materials have a smell while they’re applied. It fades as everything cures.
Is it OK to have pets in the house?
On the day, the room should be kept clear of pets and children, mainly so nothing gets touched before it has cured.
What happens next?
You get a fixed quote and available dates. If we need another angle, we will ask.
Do you charge for travel?
Travel is included in the price, with the same prices everywhere we work.
My seal keeps tearing. Why?
The bath or tray is probably flexing. If it keeps happening, the support may need fixing.
Why it’s worth resealing in Dinas
Sealing over old silicone is a false economy. It soon peels, and traps mould underneath. We remove the old sealant completely. Instead of hourly rates, we price the entire job up front. It depends on the damage, the material and access, and doing several items at once reduces it.

Landlord and trade work in Dinas
Builders use us to fix snagging damage before handover, so there is no need to replace a damaged item at the last minute. Several plots can be done in one visit to keep costs down.
Rental properties take more wear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.
Materials and what they mean for the repair
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.
