Bathroom & kitchen resealing in South Hornchurch, Greater London
Bath, shower, basin, wet room, worktop and sink resealing for homeowners, landlords and businesses in South Hornchurch. Fully insured, ARBOMaster approved and guaranteed for a year.
- Shrunken sealant along the back of a worktop
- Black spots spreading through the bead
- Water escaping at the shower enclosure
Leave it or put it right?
Bleach and mould sprays may lighten black marks for a while, but mould that has grown into the sealant tends to return. The lasting answer is to remove the bead and start again. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in South Hornchurch, the repair is bigger than a sealant job.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Bathroom resealing in South Hornchurch, done properly
The secret of a lasting bead is the preparation. The old sealant is removed to the last smear, then the joint is cleaned, degreased and treated for mould. New silicone goes on only when the joint is fully dry. If you have failed sealant on the screen profile and shrunken sealant along the back of a worktop, we can help, on wet rooms, kitchen worktops & upstands and basins & vanity units alike.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, 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 Hornchurch are no different.
There’s a 12-month guarantee on every job, whatever its size.

How it works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take around two hours for one bath or shower, longer for a whole bathroom, and we tell you how long to leave it before we go. In a London area like South Hornchurch, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We cover the area around the joints we’re working on.
- We cut away the old sealant and clean off what’s left.
- 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.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
- Mention any sign-in or site rules at work premises

Advice
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Tiles that have come away from the wall
- Cracked or missing grout between tiles (that’s regrouting)
- Leaks from a shower valve, waste or pipework (a plumber’s job)
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

Bathroom resealing in South Hornchurch: local notes
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. 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.
If you live in an older home near St John's Parish Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For site and facilities teams at buildings such as Whybridge Junior School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Questions from South Hornchurch
I let a flat near Rainham (Essex) station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Could a tired shower seal in my South Hornchurch flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Are you fully insured?
Yes. We are fully insured for every job we do.
Is it worth trying 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.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover South Hornchurch and the rest of Greater London, along with the rest of our area.
Does the resealing come with a guarantee?
Yes. All our work comes with a 12-month guarantee, and we’re fully insured.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
What we’re called out for in South Hornchurch
Baths and trays move. Acrylic in particular gives slightly under the weight of water and a person, while a poorly supported tray can shift underfoot. Over time the joint tears or pulls away from the tile.
These are the problems we are asked about most:
- Sealant that has split, shrunk or peeled away
- Leaking joints on a shower screen
- Two layers of silicone, both failing
- Black spots spreading through the bead
If you let a flat or house near Rainham (Essex) station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Stick to a soft cloth and a mild cleaner
- Let new sealant cure fully before it gets wet
- Dry worktop joints after washing up
- Never pick at the silicone with a blade
Do not stand bottles along the bead, as they hold water against it. Squeegeeing the walls and tray after use keeps water from sitting on the joint.
Mould that starts as a few spots spreads through the bead. When it has grown right through, it rarely cleans out, and nearby grout often goes the same way. Replacing the sealant early keeps the job small.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
