Knockholt: your questions answered
Can you do bathroom resealing in Knockholt?
Yes, Knockholt is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Knockholt station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you do kitchens as well as bathrooms?
Yes. Worktops, sinks and splashbacks are all part of the job, in a kitchen-suitable sealant, matched to the worktop where it’s on show.
How long does it take to reseal a bath or shower?
A single bath or shower takes about a couple of hours, including cutting out the old sealant. A full bathroom and kitchen can take most of a day.
Is the work guaranteed?
Yes. All our work comes with a 12-month guarantee.
Can mouldy silicone be sorted out?
Yes. Once mould has grown into the silicone, it normally cannot be cleaned out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.
Can new silicone go straight over the old?
No. New silicone will not bond to old silicone, so it peels away and hides mould and water. All the old sealant comes out first.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

What else we do in Knockholt
Different surfaces, different methods
Basins & vanity units
Vanity units have long, worktop-style joints against the wall. Water that gets behind can damage the unit, so the joint is sealed in one unbroken line.
Sinks & splashbacks
Water getting under the rim of an inset sink can soak the worktop. We reseal the visible edge of the sink where it has failed.
How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes half a day or less for one room, longer when the kitchen is included. Somewhere as small as Knockholt, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint first and check for movement or leaks.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, normally around 24 hours.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
- Mention any tricky access

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Common problems we fix in Knockholt
Mould is the reason many people want their sealant replaced. Bathrooms without good ventilation give mould all the damp it needs, and once it has grown into the bead, cleaning rarely gets it out.
The most common problems we see are:
- Splits where the tray meets the wall
- A bead that has pulled away from the tiles
- New sealant laid over old sealant that is now lifting
- Damp behind the bath or under the tray
If you let a flat or house near Knockholt station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Quotes for bathroom resealing in Knockholt
We do not publish a price list, because jobs vary so much. The quote depends on:
- The size of the job
- Whether old sealant or filler has to be cut out
- The product the joint needs
- How easy the joints are to reach
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Helping us quote
To make quoting easier, let us know:

We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or email us with the details, and pictures are welcome.
Knockholt homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as St Katharine's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
