Bathroom resealing in Mill Hill
A reseal only lasts if the joint is properly prepared. Every bit of old silicone comes out, down to the thin film left on the tiles, then the joint is cleaned, degreased and treated for mould. Only once it’s dry does the new bead go on. Typical jobs include splits where the tray meets the wall and mouldy sealant that has gone black, on sinks & splashbacks, kitchen worktops & upstands and basins & vanity units.
Hard London water leaves limescale on sealant, grout and taps alike. In Mill Hill, bathroom resealing is as much about a room looking cared for as about keeping water out.
There’s a 12-month guarantee on every job.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Run the extractor fan during and after every shower
- Wipe up water along the back of the worktop
- Check the joints every few months for splits or lifting
- Wait for the cure time we give you
Clean the silicone with care: warm soapy water and a soft cloth do the job. Scourers and blades can nick the surface, and a nicked bead lets mould in sooner.
Don’t wait for a refit to deal with failed sealant. Like paintwork, sealant needs renewing from time to time, and renewing it as soon as it fails protects everything around it.
Different surfaces, different methods
Shower trays & enclosures
A tray that rocks will split any sealant. Movement is checked before anything is resealed, and tell you if it needs re-bedding first.
Baths
A bath shifts slightly every time it’s filled, so it’s filled with water before the bead goes on. The joint is then laid with the bath at its lowest point.
Leave it or put it right?
Running new silicone over the old joint can look tidy for a few weeks, but it can’t stick to what’s underneath. It lifts, traps water and grows mould behind it, so the next person has twice as much to remove. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Mill Hill, the repair is bigger than a sealant job.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What bathroom resealing looks like in Mill Hill
London’s water is hard, which leaves limescale on sealant, grout and taps. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
In the older streets around St Paul's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. As a London address, Mill Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Rented homes near Mill Hill Broadway station change hands often, and fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you reseal around my kitchen sink and worktop?
Yes. We reseal worktop upstands, sinks and splashbacks, in a kitchen-suitable sealant, matched to the worktop where it’s on show.
My sealant has gone black. Can you sort it?
