About our bath resealing in Risca
A good reseal is all about preparation: every bit of old silicone out, mould treated, the joint clean and dry. Only then does the new sealant go on, as one neat, continuous bead. If you’re dealing with gaps in the seal and stained silicone, we can help, on kitchen worktops & sinks, baths and wet rooms alike.
Every repair is covered by our one-year guarantee, wherever you are in Caerphilly.

When we would advise against a repair
A few problems are outside what a surface repair can do:
- Hollow or loose tiles
- Hidden water damage
- A bath or tray that moves, until its support is fixed
Send us pictures and we will tell you honestly.

- Baths
- Basins & vanity units
- Kitchen worktops & sinks
- Shower trays & enclosures

How the visit works
On the day itself, there is little for you to do. Let us in and show us the room, and we’ll get on with it. The job generally runs to a couple of hours, including clearing up.
- We cut out all of the old sealant.
- Residue is removed and the joint cleaned.
- Any mould is treated and the joint dried.
- The bath is filled with water, or weight put on the tray.
- New mould-resistant silicone is applied and tooled neatly.
Preparing for the visit
- Point us to the nearest place to park
- Make sure the room can be ventilated
- Keep pets and children out of the room while we work
How to get a price

- Accredited with CHAS, Constructionline and SafeContractor
- We will tell you if it’s not worth repairing
- One visit for most repairs

What your bath or shower is made of matters
Baths
We fill the bath before sealing, to open the joint fully.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
DIY repairs versus a professional job
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. The trouble is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.
Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is normally cheaper.
Prices and what affects them
We price every job individually, from your photos. What matters most is:
- Any earlier repairs that need removing first
- What kind of damage it is
- How many items we do on one visit
- How hard the colour is to match
The price reflects the work involved, not where you live. You will see the full price before booking.
Getting a price from pictures
Almost every job we do is priced from pictures. This is what we need:
- A coin or ruler next to the damage for scale
- The material, if you know it
- Natural light rather than flash
- A close-up of the damage, in focus
The quickest way to a price is to send a couple of photos through our quote form or ring us. We will say immediately if a repair is the right fix.
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 hold CHAS, Constructionline and SafeContractor accreditations.
We carry out planned and one-off repairs for housing associations and facilities teams in Caerphilly and across the UK. Repairing in place avoids the disruption of a replacement, which is easier on the people living there.
