Why it’s worth resealing in Lisvane
Resealing costs very little and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. What it costs depends on how much damage there is and what kind, what it’s made of and how many items we do on one visit. You get a fixed quote from your pictures, so there are no surprises on the day.

Advice
What we are called out for in Lisvane
Most reseals are because of black mould. It grows into the silicone, so cleaning cannot get it all out.
The most common problems we’re called about are:
- Silicone smeared on tiles
- Black spots in the silicone
- Sealant that’s split or lifting
- Unsealed corners

What affects the price in Lisvane
A fixed quote means you know the cost before booking. We take into account:
- The material
- The type of damage
- How many areas need work
- How hard the colour is to match
Most people are surprised how affordable a repair is, especially compared with replacing and refitting. Photos let us give you the exact figure.
Quotes from your photos
The better the photos, the more accurate the price. Here’s what we find most useful:
- Where you are, by postcode
- A wider photo showing the whole bath or shower
- Something in shot to show the size
- Daylight if possible, and no flash reflection
For a price in Lisvane, the easiest route is pictures: a close-up, a wider shot and your postcode. We reply with a fixed quote and our next available dates.
Keeping it looking good
Looking after the surface is easy:
- Run the extractor fan during and after showers
- Do not stand toiletries on the seal
- Wipe the joints dry after use
- Clean the joints with a mild cleaner
Do not scrape the sealant with anything sharp, and keep shampoo bottles off the joints.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, so we’ll tell you if it needs a builder or plumber.
Can I fix it myself?
A DIY attempt is not a disaster. We take the old repair out and do it properly, so it does not stop a professional repair. It does add a little time, so tell us about it when you send photos.
Kits are cheap and easy to find, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Getting it right first time is generally cheaper.

What we cannot put right
A repair is not always the answer, and we’ll tell you before we start. Repairs won’t solve:
- Gaps too big for silicone alone
- A flexing bath
- Loose tiles, which need refixing first
Send us pictures and we’ll tell you honestly before booking.

Your questions about bath resealing in Lisvane
Why does my sealant keep going mouldy?
Normally poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.
Are you a vetted contractor?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Do you work in Lisvane?
Yes, we do. Repair technicians travel to Lisvane from across the region, with no extra charge for travel.
Can you repair several things at once?
Yes. Doing several items on one visit usually costs less than separate visits. Include pictures of each item.
Why does the silicone keep cracking?
Movement is the usual cause, or it was sealed with the bath empty. We fill the bath before sealing it.
What areas do you cover?
We cover the entire UK, including Lisvane and the rest of Cardiff. Send your postcode with your photos and we’ll confirm dates.
Can landlords book you?
We do, regularly. We quote for multiple addresses and fit around tenancy changeovers.
How long does resealing take?
Around two hours for a bath, plus curing time.
