How we handle bathroom resealing in Cannon Hill
Resealing is a small job that makes a big difference. Mouldy silicone makes even a new bathroom look neglected, and a clean white or clear joint fixes it quickly. It also seals the gaps that let water behind the bath. Common call-outs are for leaking joints on a shower screen and shrunken sealant along the back of a worktop, on basins & vanity units, shower trays & enclosures and wet rooms.
Hard London water leaves limescale on sealant, grout and taps alike. In Cannon Hill, bathroom resealing is as much about a room looking cared for as about keeping water out.
Each job carries a 12-month guarantee.

Different surfaces, different methods
Kitchen worktops & upstands
Laminate worktops swell if water gets into the core. A sound joint along the back edge stops that.
Baths
Acrylic baths give a little under load, and even steel and cast iron baths settle slightly when full. Loading the bath with water before sealing allows for it.

Bathrooms and kitchens in Cannon Hill
London’s water is hard, so limescale builds up on sealant, grout and fittings. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
Homes close to St James Merton include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. For site and facilities teams at buildings such as Hillcross Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Cannon Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Questions from Cannon Hill
Is parking a problem for a job in Cannon Hill?
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 worn sealant in a flat in Cannon Hill cause a leak downstairs?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
How long will the resealing take?
Allow half a day or less for one room, longer when the kitchen is included. You will know how long to expect before work begins.
Is it OK to put new sealant on top of the old bead?
No, and it’s one of the main reasons reseals fail. We cut out all of the old sealant, clean the joint and start again.
Is it worth trying it myself?
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.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Keeping the joints in good condition
Aftercare is simple:
- Dry worktop joints after washing up
- Never pick at the silicone with a blade
- Use gentle cleaners on the silicone
- Run the extractor fan during and after every shower
Don’t stand bottles along the bead, because they trap water against the silicone. Squeegeeing the walls and tray after use helps the joint dry.
A few black dots in the silicone soon become a black line. Once it’s deep in the silicone, cleaning normally won’t remove it. Catching it early keeps it a simple reseal.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning or an afternoon for most single baths and showers, and the area is left clean. In Cannon Hill, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- Joints are degreased and any mould is treated.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, usually around 24 hours.
How to prepare
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

What happens if it’s left?
A failed joint gets more costly to put right the longer it’s left. Water that gets behind a bath soaks into the floor, the panel and sometimes the ceiling below, turning a small job into a building repair. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Cannon Hill, the repair is bigger than the sealant job would have been.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we’ll talk you through it.
