Different materials, different repairs
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
We put weight on a tray before sealing it, for the same reason.
DIY kit or professional repair?
For a hairline mark somewhere you will never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair will not last.
What we can’t put right
A few problems are outside what a surface repair can do:
- Hidden water damage
- Tiles that move, until they’re refixed
- A flexing bath

What we do, step by step

- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- The bath is filled with water, or weight put on the tray.
- New mould-resistant silicone is applied and tooled neatly.

Do you need bath resealing in Knapp?
In time, even good sealant discolours, especially in a busy family bathroom. Steam, soap and movement all wear it down.
Common reasons people in Knapp contact us include:
- A messy previous reseal
- Stained silicone
- Sealant that is split or lifting
- Gaps by the taps
What your quote should include
- What happens if the damage is worse than the pictures show
- If travel is included in the price
- Whether they match the colour on site
- What the guarantee covers, and for how long
What bath resealing costs
A fixed quote means you know the cost before booking. We take into account:
- Previous DIY repairs that have to come out
- Unusual colours or finishes
- How many areas need work
- The type of damage
Every job is a little different, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all make a difference, and doing several things on one visit costs less than separate visits.
Quotes from your photos
It only takes a minute to photograph the damage, and it saves a visit. Try to send:
- Good light, ideally daylight, without flash glare
- A picture taken from further back
- Something in shot to show the size
- The material, if you know it
A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, include your postcode and send them to us. What comes back is a fixed quote, not a guess.

Keeping it looking good
Looking after the surface is easy:
- Run the extractor fan during and after showers
- Give the seal a regular clean
- Keep the joints dry
- Let steam out after showers
Keep the room well ventilated, and dry the joints after bathing to keep mould away.
Don’t wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
Common questions in Knapp
Why does mould come back so fast?
Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.
Do you seal over the old sealant?
Never over old. It’s removed, cleaned off and the joint dried first.
How quickly can you book me in?
It depends on the time of year and where you are. We’ll offer you dates when we send your quote.
It’s been repaired before. Can you still fix it?
Usually, yes. We remove the old repair before doing a new one, so mention it when you send pictures.
What does bath resealing cost?
Every job gets a fixed price from your pictures. Send a close-up of the damage and a wider photo and your postcode.
Can you repair several things at once?
Of course, and it normally saves money. Just add the extra items to your pictures and we will quote them together.
Why does the silicone keep cracking?
Something is moving. If it keeps happening, the support may need fixing.
Can tenants book a repair?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
