Bath resealing in Essendon without replacing anything
Baths, trays, basins and kitchen worktops all get resealed, with mould-resistant sanitary silicone. A typical reseal takes a couple of hours, plus curing time. If you’re dealing with a messy previous reseal and black mould in the sealant, we can normally put it right.
Every job is backed for twelve months, and the guarantee is the same wherever you live. If something goes wrong with the work, we come back.

Why reseal now?
Putting new silicone over old doesn’t last. It peels within weeks, and traps mould underneath. We remove the old sealant completely. A few things move the price: access, material, the extent of the damage and whether we can do several items together. Photos let us give you a fixed figure.

When a repair is not the answer
A repair is not always the answer, and we’ll tell you before we start. We cannot fix:
- Loose tiles, which need refixing first
- Gaps too big for silicone alone
- Rotten walls or floors behind the bath
Send us pictures and we’ll tell you honestly.
Materials we repair
- Kitchen worktops & sinks
- Baths
- Shower trays & enclosures
- Wet rooms
- Basins & vanity units
DIY kit or professional repair?
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.
The difference between a kit and a professional repair is mostly in the preparation and colour. 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.
Common questions in Essendon
Is there a call-out fee?
Travel is included in the price, with the same prices everywhere we work.
Do you do work for letting agents?
Yes. We carry out repairs for householders, landlords, letting agents, builders and businesses in Essendon.
How long before I can shower?
Typically after around 24 hours. We’ll tell you the exact time.
Is repairing better than replacing?
Typically, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. If replacing would be better, we will say so.
What information do you need?
Send pictures through the quote form or call 0345 017 0787, and we will take it from there.
Can you repair something that’s been repaired before?
Yes, we often do. It can add a little time, which we include in the quote.
Do you seal over the old sealant?
We always remove the old sealant completely. Fresh silicone doesn’t stick to old.
Do I need to be at home?
Yes. The technician needs access to the room for the visit, at a time we agree with you.
Work for landlords and builders
For developers and builders, we fix damage before handover. Several plots can be done in one visit to keep costs down.
If you manage property in Essendon, we can repair and quote for several addresses together. Just send photos for each address and we’ll come back with a combined price.
How to care for the repair
Aftercare is simple:
- Keep the joints dry
- Air the room after use
- Reseal when black spots will not clean off
- Keep bottles off the joints
Avoid scraping the joints, and do not stand bottles on the seal.
Mouldy sealant is more than a cosmetic problem, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.

- Unsealed corners
- Old sealant that looks dirty
- Black spots in the silicone
- Leaks at the edges
