Bath & shower resealing (mastic) in Trallwn, Swansea
Local bath resealing for Trallwn: a fixed quote from photos, a tidy visit and a one-year guarantee.
- Black mould in the sealant
- A messy previous reseal
- Sealant that is split or lifting
Should I try a DIY kit first?
It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
A DIY attempt is not a disaster. We remove the old filler and start again, so it doesn’t stop a professional repair. Just mention it when you send pictures, as it can add time.
Bath resealing in Trallwn without replacing anything
Baths are resealed with water in them, so the joint opens fully, which stops the new seal tearing the first time the bath is used. We are often asked to fix sealant that’s split or lifting and discoloured, yellow sealant, across shower trays & enclosures, kitchen worktops & sinks and baths.
Your repair is guaranteed for a year, as with every job we do.

When to call us in Trallwn
Sealant does not last forever. Every bath or shower adds moisture and soap residue, which mould feeds on, and the joint moves slightly every time the bath is filled.
People normally call us when they notice something like this:
- An untidy old seal
- Stained silicone
- Damp near the bath
- Silicone coming away from the tiles
What to look for in a quote
- Whether they match the colour on site
- How your room will be protected
- Whether the price is fixed and includes VAT
- How soon you can use it again
What bath resealing costs
There’s no area surcharge for Trallwn. The price reflects:
- How many items we do on one visit
- Any earlier repairs that need removing first
- What kind of damage it is
- The material
Every job is a little different, so each one is priced on its own. The size and type of damage, the material and access all make a difference, and doing several things on one visit costs less than separate visits.
How to get a fixed price
Almost every job we do is priced from pictures. This is what to send:
- Daylight if possible, and no flash reflection
- A clear, close picture of the problem area
- A photo taken from further back
- The postcode, so we can plan the visit
You do not need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we will come back to you with a fixed figure.
What we do, step by step
Here’s how a visit generally runs: we arrive on time, sheet and mask the area around the job, do the job and clear up. Allow about two hours for a bath. Before we go, we will explain when it can be used and what to avoid for the first few days.
- The surrounding area is protected and the joints masked.
- We remove the old sealant and every trace of residue.
- The joint is cleaned, treated and dried.
- We run a continuous bead of new silicone.
- We smooth the bead, remove the tape and leave it to cure.
How to prepare
- Keep children and pets away from the room on the day
- Tell us about any previous repairs or coatings
- Let us know about parking or access
How to get a price
Pricing is simple: snap the damage close up and then the entire item, send them to us with your postcode, and you’ll get a fixed price back. There is no charge for the quote and you are under no obligation.

Aftercare tips
How the surface is treated afterwards matters:
- Let steam out after showers
- Clean the sealant gently and regularly
- Ventilate the bathroom well
- Reseal when black spots will not clean off
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 will tell you if it needs a builder or plumber.
Repairs by material
Baths
We fill the bath before sealing, so the joint is at its widest.

Questions from Trallwn
Do you come to Trallwn?
Yes, we do. We send a technician to Trallwn for every job, and the price is the same as everywhere else.
Why does the silicone keep cracking?
Something is moving. Persistent splitting can mean the support needs attention.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is it OK to have pets in the house?
Please keep children and pets out of the room during the visit and until it has cured. Everywhere else in the home is fine.
Can I add another job to the visit?
Yes. Doing several items on one visit normally costs less than separate visits. Include pictures of each item.
What if the damage is worse than the pictures show?
Your quote covers the damage in the pictures. If there’s more, we’ll tell you before starting.
How do I book?
Photos of the damage, a photo of the entire bath or shower and your postcode. After that, we just agree a date.
Can you reseal over the old silicone?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
