Bathroom Resealing in St John's Wood
Baths, showers and worktops in St John's Wood need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Gaps where the bath or tray has moved
- Two layers of silicone, both failing
- Sealant that has split, shrunk or peeled away
Bathroom resealing in St John's Wood, done properly
A fresh bead of silicone changes how a bathroom looks more than most people expect. Black, patchy sealant makes clean tiles look tired, and a neat new joint puts that right in a short visit. Just as important, it closes the gaps water would otherwise get through. If you’re dealing with smears of silicone across the tiles and a bead that has pulled away from the tiles, we can put it right, on sinks & splashbacks, basins & vanity units and baths alike.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in St John's Wood more than a cosmetic job.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

St John's Wood homes and their sealant
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
For landlords with property near South Hampstead station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. In the older streets around Church of All Souls, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

St John's Wood: your questions answered
Do you take on hotel work around St John's Wood?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Can parking be tricky for a visit in St John's Wood?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
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 new silicone go straight over the old?
No. A bead laid over old silicone soon starts to come away. We remove the old bead completely before resealing.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
How long will the resealing take?
That depends on the number of joints and the state of the old sealant. Allow a couple of hours for a typical bath or shower.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you guarantee your resealing?
Yes. Our one-year guarantee covers every job, and we’re fully insured.
What affects the quote in St John's Wood
Call for a quick quote. What matters most is:
- Access and height
- How many areas need sealing
- The size of the job
- The type of sealant required
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Looking after it afterwards
To keep the joints looking good and working properly:
- Clean with a mild bathroom cleaner and a soft cloth
- Dry the bead with a towel now and then
- Avoid abrasive pads on the sealant
- Keep the fan on for a while after bathing
Clean the silicone with care: a mild bathroom cleaner and a soft cloth is enough. Avoid scouring pads and anything sharp, and a nicked bead lets mould in sooner.
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.
Different surfaces, different methods
Sinks & splashbacks
Around the sink, we use a product suited to kitchens, including a food-safe sealant where that’s needed. The joint is laid neatly so it’s easy to wipe.
Basins & vanity units
Basins take less water than showers, but the joint behind them is splashed every day. Old sealant there often goes black at the corners, and we treat it exactly as we would a bath.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Water coming from the plumbing rather than the joint
- A tray or bath that is cracked through
- Water getting in through the grout rather than the sealant
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

Common problems we fix in St John's Wood
Baths and trays move. An acrylic bath flexes under load, while a poorly supported tray can shift underfoot. That movement works at the bead until it splits or peels away.
Common reasons people contact us include:
- Gaps where the bath or tray has moved
- Water getting behind the bath panel
- Failed sealant on the screen profile
- Gaps between the worktop and the wall

Questions to ask before booking
- How long to leave it before use
- Whether all the old sealant comes out first
- The length of the guarantee
- How the colour is chosen
What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take half a day or less for one room, longer when the kitchen is included. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in St John's Wood. A visitor permit or a nearby bay makes the visit run more smoothly.
- We protect the area and cut out all of the old sealant, including the film left on the tiles.
- The joint is cleaned, degreased and treated for 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.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Tell us about any water getting in
