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: they come in a handful of shades, and if the surface is not prepared the repair won’t last.
If you’ve already tried a DIY fix, that’s fine. We take the old repair out and do it properly, so it does not stop a professional repair. It does add a little time, so tell us about it when you send photos.

FAQs for Kelshall
How do I book?
Some pictures, your postcode and how to reach you. On the day, access to the room.
Is the work guaranteed?
Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.
What happens after I send pictures?
You get a fixed quote and available dates. If anything’s unclear, we’ll ask for another photo.
How do I stop mould in sealant?
Damp is the cause. Ventilation and drying keep it clean longer.
Do you come to Kelshall?
Yes. We cover the entire UK and come to Kelshall and the rest of Cambridgeshire. Send us photos for a fixed quote, or call 0345 017 0787.
Will it make a mess?
No. The work area is masked and covered, and we take our waste away with us.
What areas do you cover?
We work UK-wide, and that includes Kelshall. Prices don’t change with location.
Do you do work for letting agents?
Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses across Cambridgeshire.
Signs you need bath resealing in Kelshall
Most reseals are because of black mould. It grows into the sealant itself, so cleaning can’t get it all out.
Signs it’s time to call us include:
- Stained silicone
- A messy previous reseal
- Gaps by the taps
- Black spots in the silicone
Comparing quotes
- What happens if the damage is worse than the pictures show
- Who will actually do the work
- Whether the price covers travel
- A fixed quote, and whether VAT is included
Aftercare tips
Nothing complicated is needed:
- Reseal when black spots won’t clean off
- Run the extractor fan during and after showers
- Keep the joints dry
- Clean the sealant gently and regularly
Use the extractor fan, dry the joints after bathing, and give them a regular clean with a mild cleaner to slow mould growth.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. It may be more than a reseal, and we’ll say if you need a builder or plumber.

Compared with repairing water damage, resealing is cheap. It’s a quick job that protects your walls and floors. We charge the same wherever you are, with no extra for Kelshall. What changes the price is the job itself: the material, the amount of damage and how many items.
