How we handle bathroom resealing in Kennington
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Kennington. We’re ARBOMaster approved and fully insured, and every job carries our one-year guarantee. If you have a messy, uneven bead from a previous reseal and damp behind the bath or under the tray, we can help, on sinks & splashbacks, kitchen worktops & upstands and basins & vanity units alike.
Hard London water leaves limescale on sealant, grout and taps alike. In Kennington, bathroom resealing is as much about a room looking cared for as about keeping water out.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a morning or an afternoon for most single baths and showers. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- 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.
- Joints are degreased and any mould is treated.
- 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, generally around 24 hours.
Preparing for the visit
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

Your questions about bathroom resealing in Kennington
I let a flat near Vauxhall station. Can you help?
Yes. We work for landlords and letting agents as well as householders. 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.
Can worn sealant in a flat in Kennington cause a leak downstairs?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you come to Kennington?
Yes. We work in Kennington and the rest of Greater London. For a quote, phone 0345 464 0079 or send us an email.
Do you reseal kitchen worktops and sinks too?
Yes. We reseal worktop upstands, sinks and splashbacks, with a sealant suited to kitchens, colour-matched where it shows.
Bathroom resealing in Kennington: local notes
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London’s water is hard, so limescale builds up on sealant, grout and fittings.
Managing a site like St Stephen's Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Calvary Church of God in Christ include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Why deal with it now?
Fresh sealant smartens a bathroom or kitchen with very little disruption, which helps when a home is being let or put on the market. Lumpy sealant with smears on the tiles has the opposite effect. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

- Experience in homes, commercial sites and hotels
- Fully insured

Surface by surface
Basins & vanity units
Vanity units have long, worktop-style joints against the wall. If water gets in, the cabinet underneath can swell, so the joint is sealed in one unbroken line.
Baths
Acrylic baths give a little under load, while steel and cast iron baths move less but still settle when full. Filling the bath first allows for that movement.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep the fan on for a while after bathing
- Wipe the sealant dry after showering
- Wait for the cure time we give you
- Move toiletries away from the joint
Wipe up standing water along the worktop joint and keep hot pans off the bead. A dry joint lasts longer.
Mould that starts as a few spots spreads through the bead. Once it’s deep in the silicone, cleaning generally will not remove it. Catching it early keeps it a simple reseal.
How we quote for bathroom resealing
We do not publish a price list, because jobs vary so much. The quote depends on:
- How many areas need sealing
- Any working-time requirements on site
- Access and height
- Which sealant suits the joint
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before any work starts.
Asking for a quote
What to tell us when you ask for a quote:
- The rough size of the job
- Photos by email, if that is easy
- How we’d reach the joints
- The address or postcode of the job
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
Signs you need bathroom resealing in Kennington
The wrong product fails fast. Acrylic caulk and general-purpose sealants aren’t designed for a joint that is wet every day, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
The problems people normally mention when they call include:
- Failed sealant on the screen profile
- Black spots spreading through the bead
- Gaps between the worktop and the wall
- Sealant that has split, shrunk or peeled away
As a London address, Kennington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
