Bath resealing in High Wych without replacing anything
Resealing is quick, but it transforms the look. Clean, white joints make a bathroom look cared for, and they keep water out. We work on shower trays & enclosures, baths and wet rooms, and people most often call us about missing sealant behind the taps and silicone smeared on tiles.

Materials and what they mean for the repair
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
Common problems we fix in High Wych
Black mould is the most common reason people reseal. It grows into the silicone, so cleaning cannot get it all out.
The things clients usually mention when they call are:
- Damp near the bath
- Missing sealant behind the taps
- An untidy old seal
- Silicone coming away from the tiles
Before booking anyone
- Whether cleaning and preparation are in the price
- Whether the price covers travel
- What happens if they find more damage
- How long it needs to cure
Can I fix it myself?
What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
A kit can be fine for a tiny mark out of sight. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.
Aftercare tips
Once the work has cured, treat it gently:
- Store bottles on a shelf
- Open a window after bathing
- Wipe the joints dry after use
- Reseal at the first sign of lifting
Keep the room well ventilated, and wipe the joints after use.
Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.
Common questions in High Wych
What does bath resealing cost?
Because every job differs, we price from photos. You will get a fixed figure before you book.
Why does the silicone keep cracking?
The bath or tray is probably flexing. If it keeps happening, the support may need fixing.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Are there extra charges for High Wych?
There’s no separate call-out charge. The fixed price covers the visit and the work.
Are you accredited?
We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Do you do work for letting agents?
We do, regularly. We quote for multiple addresses and fit around tenancy changeovers.
What happens once I’ve sent pictures?
You get a fixed quote and available dates. If we need another angle, we’ll ask.
How long does silicone take to cure?
We will give you the curing time, normally around a day.
Why reseal now?
Resealing costs very little and protects the walls and floor. Failed sealant can lead to water damage that is much more expensive. No two jobs are quite the same, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and combining jobs on one visit brings the cost down.
