Bath resealing in Trenoweth, done in place
A proper reseal starts with removing every trace of the old silicone. New silicone won’t bond to old, which is why so many DIY reseals peel. Our technicians work on basins & vanity units, baths and kitchen worktops & sinks, and common reasons people get in touch are silicone coming away from the tiles and silicone smeared on tiles.
Big or small, you get the same one-year guarantee.

How the visit works
Once we are through the door, we keep the work contained to the one room. We mask off everything nearby, the work takes a couple of hours, and we finish with a tidy-up and a look at the finished work together.
- We cut out all of the old sealant.
- Residue is removed and the joint cleaned.
- Any mould is treated and the joint dried.
- The bath is filled with water, or weight put on the tray.
- New mould-resistant silicone is applied and tooled neatly.
Getting ready for the visit
- Keep children and pets away from the room on the day
- Tell us if there are stairs or a lift
- Mention any earlier repairs or resurfacing

Advice
Resealing in Trenoweth: why it matters

Read our prices page.
Prices and what affects them
You will not pay by the hour. The price is based on:
- The size and number of damaged areas
- Where the damage is and how we get to it
- How hard the colour is to match
- Whether we combine several jobs
We charge the same wherever you are, so there’s no premium for Trenoweth. The job itself decides the price: how much damage, what it’s made of and how many items.
Getting a price from pictures
It only takes a minute to photograph the damage, and it saves a visit. Try to send:
- Your postcode, so we can check dates
- A close-up of the damage, in focus
- A wider photo showing the entire bath or shower
- What it’s made of, if you know
For most jobs, photos are all we need to give you a price. Add a line about what happened and your postcode, and we’ll reply with a fixed quote and the earliest dates we have.

Send us photos and we will tell you honestly before booking.

Repairs by material
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
Trays are sealed with weight on them, for the same reason.
DIY repairs versus a professional job
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it does not stop a professional repair. It does add a little time, so tell us about it when you send photos.
If you’re set on a kit, follow its instructions closely, and don’t use it until it has fully cured. If it fails, we can still put it right.
Common problems we fix in Trenoweth
Sealant does not last forever. Each shower leaves moisture and soap behind, which mould loves, and the joint moves slightly every time the bath is filled.
Keep an eye out for any of the following:
- Leaks at the edges
- Silicone coming away from the tiles
- Gaps by the taps
- Black spots in the silicone
What to look for in a quote
- What protection goes down before work starts
- Whether they match the colour on site
- The length of the guarantee and what it covers
- Aftercare advice
Aftercare tips
Nothing complicated is needed, just a few sensible habits:
- Give the seal a regular clean
- Don’t stand toiletries on the seal
- Let steam out after showers
- Keep the joints dry
Good ventilation is the best protection, and dry the joints after bathing so mould struggles to take hold.
Black mould in sealant is not just unsightly; it shows moisture is getting in. An early reseal keeps water where it belongs.
What else we do in Trenoweth
Your questions about bath resealing in Trenoweth
It’s been repaired before. Can you still fix it?
Most of the time. Tell us what was done before.
Do I have to be there?
Yes. We need access to the room while we work, at a time we agree with you.
Is it messy?
Very little mess: we sheet and mask everything nearby, and we leave the room clean.
What happens if you find more damage?
If we find something the pictures didn’t show, we explain it first. The price only changes if you agree.
Are you a vetted contractor?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
Can you repair several things at once?
Yes, and it’s often cheaper. Send pictures of everything together and we’ll quote them together.
Why does my sealant keep going mouldy?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
What happens after I send photos?
We come back with a fixed quote, plus dates. There is no obligation to book.
