Bathroom resealing for homes and businesses in St Johns
Resealing is a small job that makes a big difference. Black, patchy sealant makes clean tiles look tired, and a neat new joint puts that right in a short visit. It also seals the gaps that let water behind the bath. We are often asked to deal with a reseal done over the top of the old bead and splits where the tray meets the wall, across wet rooms, baths and shower trays & enclosures.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in St Johns, getting the joints right keeps water where it belongs and the room looking clean.
Whatever the size of the job, it’s backed by our one-year guarantee in St Johns and across Greater London.

FAQs for St Johns
Can worn sealant in a flat in St Johns cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Is parking an issue for bathroom resealing in St Johns?
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 I choose the colour of the sealant?
You’re not limited to white: clear, white and colours chosen to suit the room. We will talk it through when we quote.
How long does it take to reseal a bath or shower?
Allow two to three hours for a typical bath, depending on how much old sealant there is. You will know how long to expect before any work starts.
How long does the new silicone need before I use the shower?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Keep water off it for around 24 hours, or follow the cure time we give you.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Do you do kitchens as well as bathrooms?
Yes. We reseal worktop upstands, sinks and splashbacks, with a sealant suited to kitchens, colour-matched where it shows.
Should I try DIY first?
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.
Honest limits
We will always be straight with you, so here’s what sealant can’t fix:
- Failed grout lines across the wall
- Cracks in the tray itself rather than the joint
- A leaking waste, trap or valve
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Kitchen worktops & upstands
- Shower trays & enclosures
- Sinks & splashbacks
- Wet rooms
- Baths
- Basins & vanity units
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What else we do in St Johns
Landlord and commercial work in St Johns
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
What happens if it’s left?
A quick bead over the top of the old one might look better for a while, but it won’t bond. It lifts, traps water and grows mould behind it, so the next person has twice as much to remove. In a flat in St Johns, 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.
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 will explain the quote if you ask.

Bathrooms and kitchens in St Johns
London has hard water, 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, which is why it’s worth fixing early.
For an older house near a landmark such as Church of St John, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. St Johns is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Rented homes near St Johns 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
Sinks & splashbacks
Around the sink, we use a product suited to kitchens, and a food-safe product where it’s needed. The joint is laid neatly so it’s easy to wipe.
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.
