Bathroom resealing in Kings Cross: local notes
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. London’s water is hard, which leaves limescale on sealant, grout and taps.
For an older house near a landmark such as Holy Cross Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. As a London address, Kings Cross can be tricky for parking: let us know about parking bays, permits or a driveway.

About our bathroom resealing in Kings Cross
Showers work their sealant harder than baths. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. Each gets a bead of anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. If you have leaking joints on a shower screen and water getting behind the bath panel, we can help.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Kings Cross, getting the joints right keeps water where it belongs and the room looking clean.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

What affects the cost of bathroom resealing
The quote reflects the job in front of us. We take into account:
- Whether old sealant or filler has to be cut out
- The amount of work
- How easy the joints are to reach
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before we start.
Helping us quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- If someone has resealed it before
- Roughly how big the job is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
Common problems we fix in Kings Cross
The wrong product fails fast. Decorators’ caulk and all-purpose sealants are not made for constant wetting, so they crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
Keep an eye out for any of the following:
- Splits where the tray meets the wall
- Smears of silicone across the tiles
- Gaps between the worktop and the wall
- Two layers of silicone, both failing
For landlords with property near London Kings Cross station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

What happens if it’s left?
Mould removers can fade the surface of a stained bead, but where mould is inside the silicone it usually comes back. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. In a flat in Kings Cross, 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 we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’re 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 does not work out, we can still put it right.
What the job involves on each surface
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, since cooking leaves a film that stops silicone sticking. The extra cleaning is what makes the bead last.
Shower trays & enclosures
Shower trays are sealed to the wall, and enclosures are sealed to the tray and tiles. Both get soaked every time the shower runs, so both are resealed with anti-fungal sanitary silicone.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Kings Cross. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- The joint is left to dry, and baths are filled with water first.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We clear away and tell you when it can get wet, normally after around 24 hours.
How to prepare
- Mention if the joints have been sealed before
- Clear the area around the work
- Keep pets and children clear of the area while we work

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Dry the bead with a towel now and then
- Check the joints every few months for splits or lifting
- Keep the fan on for a while after bathing
- Keep scourers and sharp tools away from the bead
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. Catching it early keeps it a simple reseal.
Kings Cross: your questions answered
Is parking a problem for a job in Kings Cross?
Parking in Kings Cross, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work in hotels near Kings Cross?
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.

I rent my home. Can I book you?

Can mouldy silicone be sorted out?
Yes. We strip the bead, treat the joint and lay new anti-fungal silicone.
When can I use the bath or shower again?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Leave it around 24 hours before it gets wet, or follow the cure time we give you.

Are you ARBOMaster approved?
