Bath resealing in Graig Penllyn, done in place
Resealing is one of the simplest ways to protect your bathroom. Old, split or mouldy sealant lets water get behind the bath or tray, and resealing puts a stop to that. If you are dealing with gaps by the taps and silicone coming away from the tiles, we can typically put it right.
Every repair comes with our one-year guarantee, wherever you are in the Vale of Glamorgan.

Work for landlords and builders
We regularly work with letting and managing agents. Just send pictures, the address and how to get access and we’ll arrange it.
Landlords, letting agents and housing providers in Graig Penllyn use us as well as householders. A repair between tenants keeps the property empty for less time, and it costs much less than replacing.
The process
We work cleanly and quietly, so you can stay at home while we are there. We protect the area first, then the work takes a couple of hours. Before we leave, we explain the curing time and the aftercare.
- First we strip out every bit of the old mastic.
- Next we clean the joint and deal with mould.
- The joint is dried thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, including around the taps.
Preparing for the visit
- Have somewhere for us to park nearby if possible
- Make sure the room can be ventilated
- Tell us about any previous repairs or coatings

Advice
Is resealing worth it?
A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. The price reflects the work involved, not where you live. The full price is agreed before you book, with nothing added on the day.

Take a look at our pricing.
What bath resealing costs
You will know the full cost before you book. We look at:
- Previous DIY repairs that have to come out
- What the surface is made of
- How much damage there is
- The type of damage
Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Photos let us give you the exact figure.
Send pictures for a quote
When you take your photos, these tips help us give you a firm price:
- A wider photo showing the whole bath or shower
- Details of any past repairs
- Daylight if possible, and no flash reflection
- A clear, close picture of the problem area
Ring 0345 017 0787, or send us photos through the quote form. With one close-up and one wider picture, we can give you a fixed quote.
Aftercare tips
How the surface is treated afterwards matters:
- Let steam out after showers
- Do not stand toiletries on the seal
- Use the extractor fan
- Clean the joints with a mild cleaner
Avoid scraping the joints, and don’t stand bottles on the seal.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
Your questions about bath resealing in Graig Penllyn
Is it worth repairing rather than replacing?
Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.
How long will it take?
Typically a couple of hours, plus curing time.
Why does my sealant keep splitting?
Normally because the bath or tray moves, or it was sealed with the bath empty. We fill the bath before sealing it.
Do you come to Graig Penllyn?
Yes, we do. Technicians travel to Graig Penllyn from across the region, with no extra charge for travel.
Can new silicone go over old?
Never over old. The old sealant is cut out and the joint cleaned and dried.
What information do you need?
Photos of the damage, a picture of the whole bath or shower and your postcode. After that, we just agree a date.
Which areas do you work in?
The entire UK, including all of the Vale of Glamorgan. Just include your postcode and we’ll offer you dates.
Can you do more than one item on the same visit?
Yes. Combining jobs on one visit brings the cost down. Include pictures of each item.
DIY repairs versus a professional job
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair will not last.
If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and do not use it until it has fully cured. If it does not work out, we can still repair it properly.
Do you need bath resealing in Graig Penllyn?
Most reseals are because of black mould. It grows into the silicone, so cleaning cannot get it all out.
Customers normally contact us about:
- Missing sealant behind the taps
- Silicone smeared on tiles
- Water getting behind the bath or tray
- Gaps in the seal
