Our applicators work in South Wimbledon on bath, shower, basin, wet room, worktop and sink resealing. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.

- Lumpy, uneven sealant from a DIY attempt
What the job involves on each surface
Kitchen worktops & upstands
The joint between worktop and wall takes splashes, crumbs and cleaning sprays. The new bead is colour-matched where it shows, so the line does not stand out.
Wet rooms
In a wet room, the joints between floor and walls take standing water. They get anti-fungal sanitary silicone, and our work is on the visible joints only.
How we handle bathroom resealing in South Wimbledon
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across South Wimbledon. We are fully insured ARBOMaster approved applicators, and every job carries our 12-month guarantee. If you’re dealing with shrunken sealant along the back of a worktop and mouldy sealant that has gone black, we can help, whatever the surface.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in South Wimbledon are no different.
All of our work is guaranteed for twelve months, in South Wimbledon and everywhere else we cover.

What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes two to three hours for a typical bath, depending on how much old sealant there is. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in South Wimbledon. A visitor permit or a nearby bay makes the visit run more smoothly.
- We cover the area around the joints we’re working on.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Keep children and pets away from the work area

Related advice
South Wimbledon: your questions answered
Is parking an issue for bathroom resealing in South Wimbledon?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Wimbledon station?
Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I choose the colour of the sealant?
White and clear are the most common choices, and other colours are available to suit tiles, trays and worktops. Tell us what you’d like when you get in touch.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Are you insured?
Yes. We are fully insured.
How we quote for bathroom resealing
We quote each job individually. This is what makes a difference:
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- How much there is to do
- Whether the work is at height
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- The rough size of the job
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Bathroom resealing around South Wimbledon
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. South Wimbledon has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you live in an older home near Holy Trinity, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. South Wimbledon is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Why it’s worth doing now in South Wimbledon
A failed joint gets more costly to put right the longer it’s left. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, turning a small job into a building repair. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in South Wimbledon.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

What we’re called out for in South Wimbledon
Silicone needs a clean, dry surface without any grease to stick to. Soap residue, oils and leftover silicone film all get in the way, so a rushed job can start to lift early.
The most common problems we see are:
- Water getting behind the kitchen upstand
- A bead that has pulled away from the tiles
- A messy, uneven bead from a previous reseal
- Two layers of silicone, both failing
Rented homes near Wimbledon station change hands often, and fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
