Bath resealing in Hanwell, done in place
All of the old sealant is cut out, treat any mould, and apply fresh mould-resistant silicone. We reseal baths, showers, sinks and worktops, and that includes the awkward spots behind the taps. Our technicians work on basins & vanity units, kitchen worktops & sinks and wet rooms, and people most often call us about a messy previous reseal and missing sealant behind the taps.
You are covered after we leave: our one-year guarantee applies to every job, and we explain what it covers before booking.

What else we do in Hanwell
Can I fix it myself?
You can buy a DIY kit for most repairs, and they can make a small mark look better. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and give it the full curing time. If it doesn’t work out, we can still repair it properly.
When a repair is not the answer
Before booking, it’s worth knowing the limits:
- A flexing bath
- Very wide gaps that need a trim
- Rotten walls or floors behind the bath
Send us photos and we’ll tell you honestly.
Materials we repair
- Wet rooms
- Shower trays & enclosures
- Kitchen worktops & sinks
- Baths
- Basins & vanity units
Keeping it looking good
To keep it looking its best:
- Wipe the joints dry after use
- Air the room after use
- Run the extractor fan during and after showers
- Reseal when black spots won’t clean off
Good ventilation is the best protection, and wipe the joints after use to keep mould away.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, and we’ll say if you need a builder or plumber.
What happens on the day
We turn up at the time we agreed with you and checks the damage against your photos first. The floor and nearby surfaces are covered before any work starts. Most visits take a couple of hours, and the room is left clean and tidy.
- We cut out and remove all of the old sealant.
- The joint is cleaned and any mould treated.
- The joint is dried thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, including around the taps.
Preparing for the visit
- Mention any parking restrictions or tricky access
- Tell us about any previous repairs or coatings
- Make sure the area is dry
