Bathroom & kitchen resealing in Willesden Green, Greater London
We cover Willesden Green for bath, shower, basin, wet room, worktop and sink resealing. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Leaks into the floor or ceiling below
- Water getting behind the kitchen upstand
- Black mould in the silicone that won’t clean off
Why deal with it now?
Fresh sealant smartens a bathroom or kitchen with very little disruption, which helps when a home is being let or put on the market. A smeared, uneven DIY bead does the opposite. 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.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

About our bathroom resealing in Willesden Green
A shower joint gets soaked every day. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. They’re resealed with anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. Typical jobs include sealant that has split, shrunk or peeled away and water getting behind the kitchen upstand, on sinks & splashbacks, shower trays & enclosures and basins & vanity units.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
Big or small, you get the same 12-month guarantee.

What we’re called out for in Willesden Green
The wrong product fails fast. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they crack, discolour or grow mould quickly. Wet areas call for a sanitary silicone with an anti-fungal additive.
Look out for these signs:
- Shrunken sealant along the back of a worktop
- A bead that has pulled away from the tiles
- Leaks into the floor or ceiling below
- Gaps where the bath or tray has moved
For site and facilities teams at buildings such as Donnington Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Honest limits
To be straight with you, there are a few things sealant will not fix:
- A leaking waste, trap or valve
- A tray or bath that is cracked through
- A bath or tray that moves because it isn’t properly supported
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Joints and surfaces we work on
- Basins & vanity units
- Shower trays & enclosures
- Wet rooms
- Baths
- Sinks & splashbacks
- Kitchen worktops & upstands
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Squeegee the walls and tray after use
- Keep the fan on for a while after bathing
- Use gentle cleaners on the silicone
- Don’t leave water standing on kitchen joints
Keep bottles and razors off the sealant line, because they trap water against the silicone. A quick squeegee after showering keeps water from sitting on the joint.
Mould that starts as a few spots spreads through the bead. Once it’s deep in the silicone, cleaning normally will not remove it. Replacing the sealant early keeps the job small.
Willesden Green: your questions answered
Do you work in hotels near Willesden Green?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Could a tired shower seal in my Willesden Green flat affect the neighbours below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
How long does a bath or shower reseal take?
Allow two to three hours for a typical bath, depending on how much old sealant there is. We will confirm how long your job needs when we quote.
Can I choose the colour of the sealant?
Most people choose white or clear, but other colours can be used to suit tiles and worktops. Let us know your preference when you ask for a quote.
Can you reseal around my kitchen sink and worktop?
Yes. The old sealant is cut out and the joint degreased, because cooking grease stops silicone sticking, then a colour-matched bead is laid.
When can I use the bath or shower again?
Silicone is touch-dry quite quickly, but it takes longer to cure. Leave it around 24 hours before it gets wet, or as long as we advise for that product.
Do you have insurance?
Yes, we are fully insured for every job we do.
Can new silicone go straight over the old?
No, never. Sealing over the top looks fine for a few weeks, then lifts. Every trace of the old bead is removed first.
The process
Before we leave, we go over the finished joints with you. The visit itself normally takes half a day or less for one room, longer when the kitchen is included, depending on the size of the job. In Willesden Green, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
