Bathroom resealing for homes and businesses in Great Thorness

The bead of silicone around a bath, tray or worktop is what keeps water out of the gaps. Once it cracks or goes mouldy, water starts to find its way through into walls, panels and floors. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. If you are dealing with leaking joints on a shower screen and black mould in the silicone that won’t clean off, we can help, on sinks & splashbacks, basins & vanity units and wet rooms alike.

Being in a small place like Great Thorness makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.

There’s a 12-month guarantee on every job, large or small.

Questions from Great Thorness

What guarantee comes with bathroom resealing in Great Thorness?

All our work, in Great Thorness and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Do you cover smaller places like Great Thorness?

Yes, Great Thorness is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

I’m a tenant. Can you help?

Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.

Can landlords and businesses book you?

Yes. We work for householders, landlords, letting agents, businesses and hotels across the Isle of Wight.

Are you insured?

Yes. Mr Mastic is fully insured.

Are you an approved applicator?

Yes. We’re approved under the ARBOMaster scheme.

Where are you based?

We are a Crawley-based firm. We work across South East England, London and Scotland.

My sealant has gone black. Can you sort it?

Yes. Mould inside the bead rarely cleans out for good, so we cut it out, treat the joint and reseal with anti-fungal silicone.

How it works

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes two to three hours for a typical bath, depending on how much old sealant there is in most cases. For a village or hamlet like Great Thorness, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First the area is protected and every bit of old sealant removed.
  2. We clean and degrease the joint and treat any mould.
  3. Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
  4. We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
  5. Finally we tidy up and explain the cure time before we leave.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • On commercial sites, let us know about site rules
  • Tell us about any previous sealing or DIY attempts

Signs you need bathroom resealing in Great Thorness

Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, and a joint that looked fine soon begins to come away.

If you can see any of these, it’s time to have the joints looked at:

  • Black spots spreading through the bead
  • Leaking joints on a shower screen
  • Shrunken sealant along the back of a worktop
  • New sealant laid over old sealant that is now lifting

Around Great Thorness, as everywhere, bathroom resealing is only as good as the preparation behind it.

Our hiring checklist

What we can’t put right

New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:

  • A leaking waste, trap or valve
  • Failed grout lines across the wall
  • A tray that rocks until it’s re-bedded

If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

Joints and surfaces we work on

  • Wet rooms
  • Shower trays & enclosures
  • Baths
  • Kitchen worktops & upstands
  • Basins & vanity units
  • Sinks & splashbacks

Work for landlords, hotels and businesses

We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.

Aftercare tips

Aftercare is simple, and it makes a real difference:

  • Do not leave water standing on kitchen joints
  • Clean with a mild bathroom cleaner and a soft cloth
  • Keep the fan on for a while after bathing
  • Look for lifting corners and small gaps now and then

Mould needs damp, so keep the room aired. Run the extractor fan during and after a shower, so the silicone gets a chance to dry.

There’s no need to wait for a full refurbishment. Like paintwork, sealant needs renewing from time to time, and replacing it when it fails protects the rest of the room.

What bathroom resealing looks like in Great Thorness

Great Thorness is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

For jobs in and around Great Thorness, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Different surfaces, different methods

Wet rooms

Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.

Baths

Baths move more than any other fitting, so it’s filled with water before the bead goes on. The joint is then laid with the bath at its lowest point and is not stretched when it’s used.
