Bath resealing in Knollbury without replacing anything
Resealing is quick, but it transforms the look. Fresh joints make the entire room look cleaner, and they protect the walls and floor. Our repair technicians work on kitchen worktops & sinks, shower trays & enclosures and basins & vanity units, and common reasons people contact us are a messy previous reseal and mould you can’t clean out.
Big or small, you get the same one-year guarantee.

Prices and what affects them
A fixed quote means you know the cost before booking. We look at:
- Any earlier repairs that need removing first
- Unusual colours or finishes
- Access to the area
- How many areas need work
Set against the cost of replacement, repairing typically costs far less, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.
How to get a fixed price
Good pictures mean an accurate price. Here’s what helps:
- The postcode, so we can plan the visit
- A clear, close picture of the problem area
- Whether it’s been repaired or coated before
- One picture of the whole bath or shower
For most jobs, pictures are all we need to give you a price. Add a line about what happened and your postcode, and we will send back a fixed quote and some dates.

FAQs for Knollbury
Can you reseal over the old silicone?
No, we never seal over old silicone. The old sealant is cut out and the joint cleaned and dried.
Why does my sealant keep going mouldy?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
Is my repair covered?
Yes, for a year. If there is a problem with the work in that time, we come back and put it right.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
Do the materials smell?
A little, depending on the job. Ventilation keeps it to a minimum, and it soon fades.
How long will it take?
A bath or shower normally takes a couple of hours. It then needs time to cure.
How quickly can you book me in?
That depends on our diary for your area. Send photos with your postcode and we’ll reply with the earliest dates.
Is repairing better than replacing?
In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.
When a repair isn’t the answer
We’d rather lose a job than do one that will not last, so these are the limits:
- Hidden water damage
- Tiles that move, until they’re refixed
- Very wide gaps that need a trim
Send us pictures and we will tell you honestly before booking.
Materials we repair
- Basins & vanity units
- Shower trays & enclosures
- Wet rooms
- Kitchen worktops & sinks
- Baths
Keeping it looking good
Nothing complicated is needed, just a few sensible habits:
- Run the extractor fan during and after showers
- Dry the seal after bathing
- Reseal when black spots won’t clean off
- Let steam out after showers
Keep the room well ventilated, and dry the joints after bathing so mould struggles to take hold.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
Common problems we fix in Knollbury
Most reseals are because of black mould. It grows into the sealant itself, so cleaning cannot get it all out.
If you can see any of these, send us a picture:
- Mould you can’t clean out
- Gaps in the seal
- Damp near the bath
- Missing sealant behind the taps

What your bath or shower is made of matters
Shower trays
Trays are sealed with weight on them, for the same reason.
Baths
We fill the bath before sealing, so the joint is at its widest.

Should I try a DIY kit first?
For a hairline mark somewhere you’ll never see, a kit may be enough. 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.
A DIY attempt is not a disaster. We remove the old filler and start again, so it doesn’t stop a professional repair. It does add a little time, so tell us about it when you send photos.
