Bathroom resealing in Earl's Court
Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water behind a laminate worktop can make it swell. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. We work on sinks & splashbacks, baths and basins & vanity units, and the jobs we see most are a joint torn by a bath that flexes and a bead that has pulled away from the tiles.
Hard London water leaves limescale on sealant, grout and taps alike. In Earl's Court, bathroom resealing is as much about a room looking cared for as about keeping water out.
Each job carries a 12-month guarantee.

Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Aftercare tips
Aftercare is simple:
- Clean with a mild bathroom cleaner and a soft cloth
- Check the joints every few months for splits or lifting
- Dry the bead with a towel now and then
- Open a window or run the fan so the room dries
Treat the new bead gently when you clean: a mild bathroom cleaner and a soft cloth is enough. Scourers and blades can nick the surface, because a damaged bead gives mould a foothold.
Watch for the early signs: a corner lifting, a gap behind the bead, a dark line under the silicone or a damp patch on the ceiling below. If you spot one, it’s time to reseal.

What else we do in Earl's Court
What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes two to three hours for a typical bath, depending on how much old sealant there is. For a job in Earl's Court, parking and access are the things to plan: 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, including the film left on the tiles.
- We clean and degrease the joint and treat any mould.
- We let it dry fully and fill the bath with water before sealing.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We clear away and tell you when it can get wet, usually after around 24 hours.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Why act early in Earl's Court
Running new silicone over the old joint can look tidy for a few weeks, but it cannot stick to what’s underneath. It lifts, traps water and grows mould behind it, so the next person has twice as much to remove. 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.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

FAQs for Earl's Court
Can worn sealant in a flat in Earl's Court cause a leak downstairs?
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 on hotel work around Earl's Court?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Earl's Court.
Are you fully insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
How long does a bath or shower reseal take?
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.
Do you need bathroom resealing in Earl's Court?
The wrong product fails fast. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
If you can see any of these, it’s time to have the joints looked at:
- Cracked, shrunken or lifting silicone
- Water getting behind the kitchen upstand
- Splits where the tray meets the wall
- Damp behind the bath or under the tray
As a London address, Earl's Court can be tricky for parking: let us know about parking bays, permits or a driveway.

Bathroom resealing in Earl's Court: local notes
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
If you live in an older home near St Cuthbert's, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as St Cuthbert with St Matthias CofE Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

How the job changes by surface
Basins & vanity units
The back of a basin gets wet every time someone washes. Old sealant there often goes black at the corners, so it’s cut out and renewed just like a bath joint.
Baths
Most bath leaks begin along the long edge, especially under a shower. We finish it with a single, even bead of anti-fungal silicone.
