The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes around two hours for one bath or shower, longer for a whole bathroom. In Coney Hall, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- The joint is cleaned, degreased and treated for mould.
- We let it dry fully and fill the bath with water before sealing.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We tidy up and give you the cure time, normally around 24 hours.
How to prepare
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children

Advice
How we handle bathroom resealing in Coney Hall
The secret of a lasting bead is the preparation. Every bit of old silicone comes out, down to the thin film left on the tiles, then the joint is cleaned, degreased and treated for mould. Only once it’s dry does the new bead go on. If you have leaks into the floor or ceiling below and failed sealant on the screen profile, we can put it right, on kitchen worktops & upstands, basins & vanity units and baths alike.
Hard London water leaves limescale on sealant, grout and taps alike. In Coney Hall, bathroom resealing is as much about a room looking cared for as about keeping water out.

Questions from Coney Hall
Is parking an issue for bathroom resealing in Coney Hall?
Parking in Coney Hall, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Could a tired shower seal in my Coney Hall flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. A proper reseal before the leak starts is the easy fix.
Do you work in Coney Hall?
Yes. We’re based in Crawley and work across South East England, London and Scotland, Coney Hall included.
How long does the new silicone need before I use the shower?
We give you the cure time before we leave, and it’s normally around 24 hours. Using it sooner can damage the bead.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
How long does it take to reseal a bath or shower?
A single bath or shower takes about a couple of hours, old sealant removal included. A full bathroom and kitchen can take most of a day.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Bathrooms and kitchens in Coney Hall
London’s water is hard, so limescale builds up on sealant, grout and fittings. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
Homes close to St Francis of Assisi include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Coney Hall is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Signs you need bathroom resealing in Coney Hall
Not every tube in the shop is meant for a shower. Acrylic caulk and general-purpose sealants are not designed for a joint that’s wet every day, so they crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
Look out for any of the following:
- Water escaping at the shower enclosure
- Black mould in the silicone that will not clean off
- Water getting behind the bath panel
- Lumpy, uneven sealant from a DIY attempt
Rented homes near West Wickham 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.
What your quote should include
- What the cure time is
- How hidden problems are handled
- How much experience the applicator has
- How the surfaces are prepared before sealing
Can I do it myself?
What a professional job adds is preparation and the right 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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What the job involves on each surface
Wet rooms
In a wet room, the joints between floor and walls take standing water. They get anti-fungal sanitary silicone, working on the surface joints, not the tanking or drainage.
Baths
Acrylic baths flex the most, and even steel and cast iron baths settle slightly when full. Loading the bath with water before sealing allows for it.
When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Damage behind the tiles that needs a tiler
- A tray or bath that is cracked through
- Movement from a bath with loose feet or no proper support
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Kitchen worktops & upstands
- Baths
- Wet rooms
- Basins & vanity units
- Shower trays & enclosures
- Sinks & splashbacks
Aftercare tips
A little care helps the new joints last. We recommend:
- Check the joints every few months for splits or lifting
- Clean with a mild bathroom cleaner and a soft cloth
- Squeegee the walls and tray after use
- Open a window or run the fan so the room dries
Do not stand bottles along the bead, as they hold water against it. Squeegeeing the walls and tray after use helps the joint dry.
A split bead lets water through every time the bath or shower is used. Over time that water reaches floors, walls and ceilings. Resealing early stops it.
