Bathroom resealing in Keston
Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints all take splashes every day, and water behind a laminate worktop can make it swell. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. If you’re dealing with two layers of silicone, both failing and cracked, shrunken or lifting silicone, we can put it right.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Keston, getting the joints right keeps water where it belongs and the room looking clean.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Looking after it afterwards
After the cure time, these simple habits help:
- Dry the bead with a towel now and then
- Wipe up water along the back of the worktop
- Run the extractor fan during and after every shower
- Stick to a soft cloth and a mild cleaner
Good ventilation does more than any cleaner. Run the extractor fan during and after a shower, so the silicone gets a chance to dry.
Watch for the early signs: lifting ends, gaps, dark shadows under the bead or a stain downstairs. Any of these means the joint needs attention.
Leave it or put it right?
Most of the work in a good reseal happens before any silicone goes on: removing all the old sealant, degreasing the joint, treating mould and drying it properly. Skip those steps and even the best silicone fails early. In a flat in Keston, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What else we do in Keston
What we’re called out for in Keston
The wrong product fails fast. Acrylic caulk and general-purpose sealants are not designed for a joint that is wet every day, so they crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
Any of these means the joints need attention:
- Cracked, shrunken or lifting silicone
- Black spots spreading through the bead
- Water getting behind the bath panel
- Gaps where the bath or tray has moved
In the older streets around Keston Parish Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- What happens if they find a problem under the old sealant
- How the colour is chosen
- What guarantee comes with the work
- What product goes in the joint
Keston homes and their sealant
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London’s water is hard, so limescale builds up on sealant, grout and fittings.
If you look after a building such as Keston Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Hayes (Kent) 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.

Different surfaces, different methods
Basins & vanity units
A vanity top has a joint along the wall and sometimes at the sides. Water that gets behind can damage the unit, so the joint is sealed in one unbroken line.
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.
How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes around two hours for one bath or shower, longer for a whole bathroom. In a London area like Keston, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start by protecting the area and stripping out the old bead.
- The joint is cleaned, degreased and treated for mould.
- We let it dry fully and fill the bath with water before sealing.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts

Advice
Questions from Keston
Can you help a landlord with a rental near Hayes (Kent) station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Could a tired shower seal in my Keston flat affect the neighbours below?
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.
Do you reseal kitchen worktops and sinks too?
Yes. The old sealant is cut out and the joint degreased, because cooking grease stops silicone sticking, then we reseal in a colour to suit.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Keston, along with the rest of our area.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
