Bath Resealing in Pontprennau
Fixed-price bath resealing in Pontprennau and the surrounding area, usually in one visit and guaranteed for a year.
- Discoloured, yellow sealant
- Water getting behind the bath or tray
- An untidy old seal
Looking after it afterwards
To keep it looking its best:
- Run the extractor fan during and after showers
- Reseal when black spots will not clean off
- Don’t stand toiletries on the seal
- Give the seal a regular clean
Keep the room well ventilated, and dry the joints after bathing to keep mould away.
Black mould in sealant isn’t just unsightly; it shows moisture is getting in. An early reseal keeps water where it belongs.
About our bath resealing in Pontprennau
A proper reseal starts with removing every trace of the old silicone. New silicone will not bond to old, which is why many DIY jobs peel. We are often asked to fix mould you can’t clean out and stained silicone, across kitchen worktops & sinks, wet rooms and basins & vanity units.
Your repair is guaranteed for a year, as with every job we do.

What else we do in Pontprennau
Different materials, different repairs
Baths
We fill the bath before sealing, to open the joint fully.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
Landlord and trade work in Pontprennau
Housing associations and facilities teams use us for planned and reactive repairs in Cardiff and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.
We regularly price jobs from inventory or check-out pictures. You can have a price before you arrange access, and we liaise with tenants about access if you’d like us to.
Honest limits
Not everything can be repaired, and we’ll tell you before we start. Repairs won’t solve:
- Loose tiles, which need refixing first
- Hidden water damage
- Movement in the bath or tray

Can I fix it myself?
Kits are cheap and easy to find, but the repairs we redo most often are DIY ones that have discoloured or lifted. Getting it right first time is normally cheaper.
If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.
FAQs for Pontprennau
It’s been repaired before. Can you still fix it?
Generally, yes. The old repair comes out first.
Do you charge for travel?
No. Our quotes include travel, and we charge the same wherever you are.
What happens after I send photos?
You get a fixed quote and available dates. If anything’s unclear, we’ll ask for another photo.
How quickly can you book me in?
It depends on the time of year and where you are. Send photos with your postcode and we will reply with the earliest dates.
Will the price change on the day?
It’s rare, but if it happens we talk to you first. You decide whether to go ahead.
Is it messy?
Very little mess: we sheet and mask everything nearby, and we leave the room clean.
How much does bath resealing cost in Pontprennau?
The exact price depends on the damage, so we quote from pictures. You will get a fixed figure before booking.
Can pets and children be at home?
We ask you to keep children and pets out of the room while we work and until it has cured. Everywhere else in the home is fine.
Is resealing worth it?
Resealing is routine maintenance. Leaving split or mouldy sealant can let water reach the walls and floor, and that damage costs much more to fix. Instead of hourly rates, we fix the price before we start. Damage, material and access decide it, and combining items on one visit brings it down.

Prices and what affects them
We do not charge extra for travel to Pontprennau. The price depends on:
- Where the damage is and how we get to it
- What kind of damage it is
- What the surface is made of
- Any earlier repairs that need removing first
No two jobs are quite the same, so we price each one individually. What’s damaged, how badly and how easy it is to reach all make a difference, and doing several things on one visit costs less than separate visits.
Send pictures for a quote
We price nearly every job from pictures. This is what to send:
- One sharp close-up of the damage
- What it’s made of, if you know
- Good light, ideally daylight, without flash glare
- Where you are, by postcode
The quickest way to a price is to send two or three pictures through our quote form or call us. We’ll tell you honestly if a repair is the right fix.
