Bathroom resealing in Harrow on the Hill, done properly
Showers work their sealant harder than baths. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. Each gets a bead of anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. We are often asked to deal with two layers of silicone, both failing and leaks into the floor or ceiling below, across baths, basins & vanity units and shower trays & enclosures.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Harrow on the Hill, bathroom resealing is as much about a room looking cared for as about keeping water out.
Each job carries a 12-month guarantee, whatever its size.

Signs you need bathroom resealing in Harrow on the Hill
Baths and trays move. Acrylic in particular gives slightly under the weight of water and a person, and a tray that isn’t fully bedded can rock. Over time the joint tears or pulls away from the tile.
If you can see any of these, it’s time to have the joints looked at:
- Shrunken sealant along the back of a worktop
- Smears of silicone across the tiles
- New sealant laid over old sealant that is now lifting
- Leaking joints on a shower screen
Managing a site like St George’s Primary Catholic Voluntary Academy? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
What to look for in a quote
- Whether they’re fully insured
- When the joint can take water or movement
- Which sealant they’ll use, and why
- Is VAT in the price?
Keeping the joints in good condition
So the new joints stay in good condition:
- Let new sealant cure fully before it gets wet
- Do not let bottles sit on the bead
- Look for lifting corners and small gaps now and then
- Use gentle cleaners on the silicone
Keep water off the new bead until it has cured, following the cure time we give you. After that, a quick wipe after showering helps keep it clean.
A failed kitchen joint is easy to miss. Splashes run behind the back edge and soak into the worktop, where it can make the board swell. Resealing before that happens protects the worktop.
The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. In Harrow on the Hill, 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.
- We cover the area around the joints we’re working on.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in

Landlord and commercial work in Harrow on the Hill
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What the job involves on each surface
Baths
A bath shifts slightly every time it’s filled, so we fill it with water before sealing. The joint is then laid with the bath at its lowest point and isn’t stretched when it’s used.
Sinks & splashbacks
Where a splashback meets the worktop, there’s a joint that catches every splash. We renew it in clear, white or a matched colour.
