Can I fix it myself?
The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
If you’ve already tried a DIY fix, that’s fine. We take the old repair out and do it properly, so it won’t stop us repairing it. It does add a little time, so tell us about it when you send photos.
About our bath resealing in Maritime Quarter
A reseal is a small job that makes a big difference. Clean, white joints make a bathroom look cared for, and they keep water out. Whether it’s stained silicone and silicone smeared on tiles, we can help, whatever the material.
We guarantee the work for a year. If there is a problem with the repair within the year, we return and sort it.

What we are called out for in Maritime Quarter
Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning only removes the surface.
Contact us if you’ve noticed:
- Silicone smeared on tiles
- Gaps by the taps
- Sealant that’s split or lifting
- Discoloured, yellow sealant

When a repair is not the answer
We’d rather lose a job than do one that won’t last, so these are the limits:
- Gaps too big for silicone alone
- Hidden water damage
- Hollow or loose tiles
Not sure? Send photos and we will give you a straight answer before you book.

What your bath or shower is made of matters
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Baths
We fill the bath before sealing, to open the joint fully.
Looking after it afterwards
Nothing complicated is needed:
- Clean the sealant gently and regularly
- Keep the joints dry
- Reseal when black spots won’t clean off
- Let steam out after showers
Use the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
Black mould in sealant is not just unsightly; it shows moisture is getting in. An early reseal keeps water where it belongs.
Maritime Quarter questions
My seal keeps tearing. Why?
The bath or tray is probably flexing. Persistent splitting can mean the support needs attention.
Can new silicone go over old?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
