How we price bath resealing
There is no charge for travel to Trealaw. The price comes down to:
- Where the damage is and how we get to it
- What kind of damage it is
- How hard the colour is to match
- The size and number of damaged areas
It helps to know what pushes a price up or down: access, material, the extent of the damage and whether we can do several items together. Send photos and you’ll get a fixed figure.
Getting a price from photos
The better the photos, the more accurate the price. Here’s what we find most useful:
- Whether it’s been repaired or coated before
- One sharp close-up of the damage
- Any details about the material
- Good light, ideally daylight, without flash glare
No survey visit is needed: we price from photos. Use the quote form, or ring 0345 017 0787 to talk it through, and we will come back with a fixed figure.

What happens on the day
We work cleanly and quietly, so you can stay at home while we are there. Protection goes down first, then the job itself 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.
- We clean the joint and treat any mould.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, taps included.
How to prepare
- Have somewhere for us to park nearby if possible
- Tell us about parking, stairs or access
- Let us know if it has been repaired before
How to get a price
There is no need for us to visit first. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed quote.
Advice
Aftercare tips
Once the work has cured, treat it gently:
- Ventilate the bathroom well
- Clean the sealant gently and regularly
- Reseal when black spots won’t clean off
- Don’t stand toiletries on the seal
Do not scrape the sealant with anything sharp, and keep shampoo bottles off the joints.
Mouldy sealant is more than a cosmetic problem. An early reseal keeps water where it belongs.

Is resealing worth it?
Resealing costs very little, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. We charge the same wherever you are, with no extra for Trealaw. What changes the price is the job itself: the material, the amount of damage and how many items.
Why book with us

Can I fix it myself?
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is normally cheaper.
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.
When we would advise against a repair
In fairness, there are a few things a repair will not fix:
- A flexing bath
- Rotten walls or floors behind the bath
- Tiles that move, until they’re refixed
Send us photos and we’ll tell you honestly.
What we work on
- Baths
- Shower trays & enclosures
- Basins & vanity units
- Wet rooms
- Kitchen worktops & sinks
Landlords, agents and businesses in Trealaw
Letting agents frequently send us photos straight from the inventory. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.
We’re used to working with agents and managing companies. Just send photos, the address and how to get access and we will handle the rest.
Common questions in Trealaw
Which areas do you work in?
All of Rhondda Cynon Taff, and the rest of the UK. Travel is included in the price.
How long does a reseal take?
A bath or shower typically takes a couple of hours. It then needs time to cure.
Is it worth repairing rather than replacing?
Typically, when the rest is in good condition. A repair avoids removal and making good. If replacing would be better, we will say so.
How long does silicone take to cure?
You will get the curing time from us, usually around a day.
How do I stop mould in sealant?
Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.
Do you do work for letting agents?
Yes, often. We quote for multiple addresses and fit around tenancy changeovers.
What if the damage is worse than the photos show?
We stop, show you and agree any change before carrying on. Nothing extra is done without your say-so.
Is the work guaranteed?
Every repair comes with a one-year guarantee. We will explain what it covers when we quote.
Different materials, different repairs
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
