Materials and what they mean for the repair
Shower trays
We put weight on a tray before sealing it, for the same reason.
Baths
We fill the bath before sealing, to open the joint fully.
Looking after it afterwards
Looking after the surface is easy:
- Let steam out after showers
- Clean the sealant gently and regularly
- Use the extractor fan
- Reseal at the first sign of lifting
Use the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
Work for landlords and builders
Rented homes see more wear and tear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.
We also carry out snagging repairs for builders and developers, fixing chips and scratches before handover. We are CHAS, Constructionline and SafeContractor accredited.

DIY kit or professional repair?
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it doesn’t stop a professional repair. Just mention it when you send pictures, as it can add time.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is typically cheaper.
Is resealing worth it?
A professional reseal costs little compared with water damage. It’s a quick job that protects your walls and floors. It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

What bath resealing costs
We price every job individually, from your pictures. What matters most is:
- The material
- The size and number of damaged areas
- What kind of damage it is
- The colour and finish to match
Compared with replacing, a repair is normally a fraction of the price, because there is no removal, plumbing or making good. The quote lists exactly what you’re paying for.
How to get a fixed price
We price nearly every job from pictures. This is what to send:
- A clear, close picture of the problem area
- A coin beside the damage so we can judge size
- Whether it’s been repaired or coated before
- A picture taken from further back
We price from photos so you don’t have to wait in for a survey. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through.
What we can’t put right
We’d rather lose a job than do one that won’t last, so these are the limits:
- Movement in the bath or tray
- Tiles that move, until they’re refixed
- Water damage behind the bath that needs a builder
If in doubt, send pictures and we’ll say what we think before you book.
Materials we work on in Flash
- Baths
- Basins & vanity units
- Kitchen worktops & sinks
- Shower trays & enclosures

The process
Once we’re through the door, the aim is to do the job without disturbing the rest of your home. Surfaces nearby are masked off, the work takes about two hours for a bath, depending on what we find, and we finish by cleaning up and talking you through the result.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
Preparing for the visit
- Clear the area around the damage
- Let us know if it has been repaired before
- Ensure the area is dry
