Bathroom resealing in Netherne on-the-Hill
Showers work their sealant harder than baths. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. Each gets a bead of anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. If you’re dealing with a bead that has pulled away from the tiles and leaks into the floor or ceiling below, we can help, on sinks & splashbacks, shower trays & enclosures and kitchen worktops & upstands alike.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Netherne on-the-Hill, getting the joints right keeps water where it belongs and the room looking clean.
All of our work is guaranteed for twelve months, in Netherne on-the-Hill and everywhere else we cover.

How the job changes by surface
Shower trays & enclosures
There are usually two jobs in a shower: the tray-to-wall joint and the enclosure joints. Both get soaked every time the shower runs, so both are resealed with anti-fungal sanitary silicone.
Baths
Acrylic baths give a little under load, and even steel and cast iron baths settle slightly when full. Filling the bath first allows for that movement.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a morning or an afternoon for most single baths and showers. In Netherne on-the-Hill, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- 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.
- The joint is left to dry, and baths are filled with water first.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We tidy up and give you the cure time, usually around 24 hours.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

Advice
How to look after the new joints
So the new joints stay in good condition:
- Dry the bead with a towel now and then
- Stick to a soft cloth and a mild cleaner
- Move toiletries away from the joint
- Open a window or run the fan so the room dries
Check the sealant now and then. Small splits and lifting ends are easy to catch early, and if anything looks wrong, just ring 0345 464 0079 or send us an email.
A failed kitchen joint is easy to miss. Water gets behind the upstand and into the edge of a laminate worktop, and the board underneath can swell. Resealing before that happens protects the worktop.
Netherne on-the-Hill: your questions answered
Is parking an issue for bathroom resealing in Netherne on-the-Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can worn sealant in a flat in Netherne on-the-Hill cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you do kitchens as well as bathrooms?
Yes, often alongside a bathroom. Where it’s needed by the sink, we use a food-safe sealant.
What colours of sealant can you use?
You are not limited to white: white, clear and colours to suit tiles and worktops. We can help you pick when we quote.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
For anyone letting property in or around Netherne on-the-Hill, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
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.
Bathroom resealing around Netherne on-the-Hill
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.

Schools such as Coulsdon Sixth Form College are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. For an older house near a landmark such as Church of St Margaret, walls and floors in older homes can move, and sealant and grout show it first.
