What we do, step by step

- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- The bath is filled with water, or weight put on the tray.
- We apply fresh mould-resistant silicone and tool a neat bead.

Common problems we fix in Blackwater
Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning only removes the surface.
These are the problems we are asked about most:
- Water getting behind the bath or tray
- Black mould in the sealant
- Silicone smeared on tiles
- Sealant that’s split or lifting

Repairs by material
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Shower trays
Trays are sealed with weight on them, for the same reason.
Looking after it afterwards
How the surface is treated afterwards matters. Here’s what we suggest:
- Let steam out after showers
- Wipe the joints dry after use
- Replace the seal when mould sets in
- Store bottles on a shelf
Use the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
Damp below or loose tiles need checking quickly. There may be more going on, and we’ll say if you need a builder or plumber.

Work for landlords and builders

Questions from Blackwater
How long will it take?
A bath or shower normally takes a couple of hours. It then needs time to cure.
Can pets and children be at home?
Just keep them out of the work area. We will tell you when the room can be used again.
Are there extra charges for Blackwater?
There’s no separate call-out charge. Your fixed quote includes everything.
What information do you need?
Some pictures, your postcode and how to reach you. On the day, access to the room.
Is there any odour?
A little, depending on the job. Open windows and an extractor fan help.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What happens after I send pictures?
We review the pictures and send a fixed quote and the next dates we have.
Why does mould come back so fast?
Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.
DIY kit or professional repair?
If you are set on a kit, follow its instructions closely, make sure the area is clean and completely dry, and give it the full curing time. If it does not work out, we can still repair it properly.
What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.
What affects the price in Blackwater
We do not charge extra for travel to Blackwater. The price depends on:
- Unusual colours or finishes
- The size and number of damaged areas
- How easy the damage is to reach
- Any earlier repairs that need removing first
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 will get a fixed figure.
