Trevaughan: your questions answered
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 information do you need?
Just photos, your postcode and a contact number. On the day, access to the room.
Can I add another job to the visit?
Of course, and it usually saves money. Just add the extra items to your pictures and we’ll quote them together.
What does bath resealing cost?
Because every job differs, we price from photos. You will get a fixed figure before booking.
Do you work in Trevaughan?
We do. Technicians travel to Trevaughan from across the region, and the price is the same as everywhere else.
Can new silicone go over old?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
Can pets and children be at home?
We ask you to keep children and pets out of the room while we work. The rest of the house is unaffected.
Is the work guaranteed?
Yes, for a year. If there’s a problem with the work in that time, we come back and put it right.
Bath resealing in Trevaughan without replacing anything
All of the old sealant is cut out, treat any mould, and reseal with new mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. Our technicians work on baths, wet rooms and basins & vanity units, and people most often call us about leaks at the edges and unsealed corners.
You’re covered after we leave: each job carries a one-year guarantee, and we explain what it covers before booking.

Keeping it looking good
Simple care helps the repair last. We recommend:
- Don’t stand toiletries on the seal
- Let steam out after showers
- Give the seal a regular clean
- Ventilate the bathroom well
Keep the room well ventilated, and wipe the joints after use so mould struggles to take hold.
Don’t wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
What happens on the day
Expect a friendly, tidy visit. We agree the arrival time in advance, cover and mask the work area, and get on with the job, which typically takes around two hours. If we find something your photos didn’t show, we’ll explain it before carrying on.
- We cut out all of the old sealant.
- Residue is removed and the joint cleaned.
- Any mould is treated and the joint dried.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
Before we arrive
- Clear toiletries, mats and anything else from around the area
- Open a window if you can
- Tell us if there are stairs or a lift
Getting a price
The quickest way to a price is to send a couple of photos through our quote form or call us. We’ll say right away if a repair is the right fix.

When we’d advise against a repair
In fairness, some problems need a different fix:
- Rotten walls or floors behind the bath
- Very wide gaps that need a trim
- A flexing bath
Send us pictures and we’ll tell you honestly before booking.
Materials we repair
- Basins & vanity units
- Baths
- Shower trays & enclosures
- Wet rooms
- Kitchen worktops & sinks
Different materials, different repairs
Baths
We fill the bath before sealing, to open the joint fully.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Why reseal now?
Sealing over old silicone is a false economy. It peels within weeks, and traps mould underneath. We remove the old sealant completely. We don’t add extras on the day. What we quote from your pictures is what you pay, and if the damage turns out to be different, we discuss it before starting.
