How we handle bathroom resealing in Kidbrooke
Sealant is the soft line between a bath, shower or worktop and the wall. Once it cracks or goes mouldy, water starts to find its way through. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. Typical jobs include a bead that has pulled away from the tiles and water getting behind the kitchen upstand, across shower trays & enclosures, sinks & splashbacks and basins & vanity units.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Kidbrooke, getting the joints right keeps water where it belongs and the room looking clean.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

What happens if it’s left?
Running new silicone over the old joint can look tidy for a few weeks, but it can’t stick to what’s underneath. Water creeps under it and mould follows, and the next reseal means two layers to cut out. In a flat in Kidbrooke, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

How the job changes by surface
Baths
Acrylic baths flex the most, and even steel and cast iron baths settle slightly when full. Filling the bath first allows for that movement.
Wet rooms
Wet rooms rely on sound joints at floor and wall junctions. They get anti-fungal sanitary silicone, working on the surface joints, not the tanking or drainage.
Bathroom resealing around Kidbrooke
Kidbrooke has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. 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.
As a London address, Kidbrooke can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St Barnabas, walls and floors in older homes can move, and sealant and grout show it first. If you look after a building such as Henwick Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Kidbrooke questions
Can you help a landlord with a rental near Kidbrooke station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can parking be tricky for a visit in Kidbrooke?
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 you get rid of the black mould in my sealant?
Yes. The old sealant comes out, the mould is treated, and we reseal with anti-fungal sanitary silicone.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can new silicone go straight over the old?
No. A bead laid over old silicone soon starts to come away, because silicone does not bond to silicone. We remove the old bead completely before resealing.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes around two hours for one bath or shower, longer for a whole bathroom, including the tidy-up. In a London area like Kidbrooke, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We cover the area around the joints we are working on.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions

Honest limits
It helps to know what we cannot do:
- Loose or hollow tiles, or failed tanking behind them
- A tray that rocks until it’s re-bedded
- A leaking waste, trap or valve
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on
- Kitchen worktops & upstands
- Sinks & splashbacks
- Wet rooms
- Baths
- Basins & vanity units
- Shower trays & enclosures
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
