Our bathroom resealing service in CR8

Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water behind a laminate worktop can make it swell. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. We’re often asked to deal with mouldy sealant that has gone black and gaps between the worktop and the wall, across wet rooms, shower trays & enclosures and basins & vanity units.

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a couple of hours for a single bath or shower, depending on the size of the job.

  1. First, each joint is checked for movement and signs of water.
  2. Every trace of the old bead is removed, including the thin smear on the tiles.
  3. The joint is cleaned, degreased and treated for mould.
  4. With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
  5. The bead is tooled smooth and you are told the cure time, usually around 24 hours.

Where we work in CR8

In CR8, bathroom resealing takes in flats, houses, rentals and businesses, from Croydon, Coulsdon and Purley to the quieter places in between. Wherever the job is, all the old material comes out before anything new goes in.

The South East is one of the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across CR8 is planned around the weather.

Purley: If you look after a building such as Christ Church CofE Primary School (Purley), we reseal washrooms and kitchens in schools and businesses as well as homes. Purley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Honest limits

It helps to know what we can’t do too:

  • Cracked or missing grout between tiles (that is regrouting)
  • A cracked shower tray or bath (that needs repair or replacement)
  • A bath or tray that moves because it isn’t properly supported

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

How to look after the new joints

No joint lasts for ever, but care makes a real difference. Our tips:

  • Wait for the cure time we give you
  • Check the joints every few months for splits or lifting
  • Keep the fan on for a while after bathing
  • Keep bottles off the sealant line

Good ventilation does more than any cleaner. Use the fan, or open a window, while you bathe and for a while afterwards, so the silicone gets a chance to dry.

A failed kitchen joint is easy to miss. Water gets behind the upstand and into the edge of a laminate worktop, where it can make the board swell. Resealing before that happens protects the worktop.

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Housing providers, facilities teams and property managers book us too in CR8 and across Greater London. We can quote a run of properties together, and we’re fully insured for the work.

Different surfaces, different methods

Shower trays & enclosures

Water often gets past the wall profile of a shower enclosure. It’s resealed along with the tray joints, sealing the side the enclosure’s instructions call for.

Basins & vanity units

On a basin, neatness shows: so we keep the line tidy and even, in white, clear or a colour to suit.

CR8 questions

Can you just seal over the old silicone?

No. New silicone won’t bond to old silicone, so it lifts and traps water and mould underneath. We always take the old sealant out completely.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.

My sealant has gone black. Can you sort it?

Yes. Once mould has grown into the silicone, it normally cannot be cleaned out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status.
