What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a couple of hours for a single bath or shower. In a small place like Knockholt Pound, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you’re told the cure time, usually around 24 hours.
Before we arrive
- Move anything stored near the joints
- Mention any parking rules near the property
- Keep children and pets away from the work area

About our bathroom resealing in Knockholt Pound
It isn’t only bathrooms. Worktop upstands, sink edges and splashback joints all take splashes every day, and water that gets into the back edge of a worktop can swell the board. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. We’re often asked to deal with new sealant laid over old sealant that is now lifting and a bead that has pulled away from the tiles, on baths, wet rooms and kitchen worktops & upstands.
In a village or hamlet like Knockholt Pound, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Every job comes with a one-year guarantee, wherever you are in Kent.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Common questions in Knockholt Pound
Do you work for landlords with property near Knockholt station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Knockholt Pound?
Yes. Knockholt Pound is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can you reseal around my kitchen sink and worktop?
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 the new silicone need before I use the shower?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Keep water off it for around 24 hours, or as long as we advise for that product.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Aftercare tips
A little care helps the new joints last. We recommend:
- Squeegee the walls and tray after use
- Never pick at the silicone with a blade
- Wait for the cure time we give you
- Do not let bottles sit on the bead
Check the sealant now and then. A small split or a corner lifting is easy to spot, so if something doesn’t look right, just ring 0345 464 0079 or email us.
Each shower pushes a little more water through a failed joint. Over time that water reaches floors, walls and ceilings. Early resealing closes the gap before damage is done.
When something else is needed
It helps to know what we cannot do:
- A bath or tray that moves because it is not properly supported
- Cracked or missing grout between tiles (that’s regrouting)
- Water coming from the plumbing rather than the joint
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

When to call us in Knockholt Pound
Sealing over old silicone is one of the commonest mistakes we find. New silicone will not bond to old silicone, so it lifts, lets water in and traps mould underneath.
Common reasons people contact us are:
- Mouldy sealant that has gone black
- A reseal done over the top of the old bead
- Sealant that has split, shrunk or peeled away
- Leaking joints on a shower screen
Homes close to St Katharine's Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Surface by surface
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.
Basins & vanity units
On a basin, neatness shows: the bead is right in front of you, so it’s tooled cleanly and evenly, finished in a colour that suits the basin.
Bathroom resealing around Knockholt Pound
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
If you let a flat or house near Knockholt station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. Schools such as Halstead Community Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
