Sealant Repair (Sanitary)
Sanitary sealant repair restores the waterproof silicone bead around baths, showers and basins. Replacing split, loose or mouldy sealant helps prevent water ingress that can lead to damp, staining and damage behind tiles or units, while leaving a clean, neat finish.
More information
What sanitary sealant repair covers
Sanitary sealant repair focuses on renewing the silicone bead where water regularly sits or splashes, so the area seals properly again.
- Removal of failed or contaminated silicone
- Careful preparation of edges for good adhesion
- Application of sanitary-grade silicone for a smooth, watertight bead
- Resealing around baths, shower trays, enclosure frames and basins
- Visual checks to confirm coverage and a tidy finish
When this service is the right fit
This service is most useful when you want a reliable seal, without guesswork, and you need the area back in use with minimal disruption.
Common reasons to book include:
- Cracked, lifting or missing sealant
- Persistent black mould that returns after cleaning
- Water escaping onto floors or into gaps at the bath edge
- Sealant that feels soft, sticky, or has shrunk away
- Pre-tenancy or changeover refresh for rental bathrooms and washrooms
What to expect on the day
The area is assessed first to confirm whether the issue is limited to sealant or if there is a wider leak or movement problem.
Typical steps include:
- Protecting nearby surfaces and removing the old silicone fully
- Cleaning and drying the joint to help the new seal bond properly
- Applying fresh sanitary silicone and tooling it for a consistent finish
- Final checks and clear advice on curing time before getting the area wet
Aftercare and ongoing value
Good aftercare helps the new seal last longer.
You will be advised on:
- How long to leave the sealant to cure before using the bath or shower
- Simple cleaning habits that reduce mould build-up
- What warning signs to watch for if movement or an underlying leak returns
