How we handle bathroom resealing in Alperton

Sealant that’s mouldy, cracked or peeling is worth sorting before it lets water through. A photo of the joints helps when you ring 0345 464 0079 or drop us an email, and you’ll get a clear quote for bathroom resealing in Alperton. If you have damp behind the bath or under the tray and gaps between the worktop and the wall, we can put it right, whatever the surface.

London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Alperton, bathroom resealing is as much about a room looking cared for as about keeping water out.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How the job changes by surface

Wet rooms

Wet room floors move slightly as they’re used, so the corners need a flexible seal, not grout. Where grout in a corner has cracked, we can replace it with sealant.

Basins & vanity units

A vanity top has a joint along the wall and sometimes at the sides. If water gets in, the cabinet underneath can swell, so the joint is sealed in one unbroken line.

What affects the cost of bathroom resealing

We quote each job individually. These are the things that affect it:

  • How easy the joints are to reach
  • When we can work, for business premises
  • The size of the job
  • How much old sealant there is and how hard it is to remove

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

What we need to know

Before you ask for a quote, have a think about:

  • Where the property is
  • What the problem is, such as mould, gaps, leaks or cracking
  • If someone has resealed it before
  • The rough size of the job

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work and give you a clear quote.

How the visit works

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen for a typical job. For a job in Alperton, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. We look at every joint first and check for movement or leaks.
  2. The old silicone is cut out completely, along with the film it leaves on the tiles.
  3. Joints are degreased and any mould is treated.
  4. When the joint is dry, and a bath has been filled with water, the new silicone goes on.
  5. We tool the bead to a neat finish and give you the cure time, generally around 24 hours.

Preparing for the visit

  • Move anything stored near the joints
  • Let us know if you’ve seen damp or leaks
  • Let us know about parking restrictions

Why it’s worth doing now in Alperton

Dealing with sealant early is a short job: it takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Wait for a leak and you may be looking at panels off, drying out and redecorating too. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Alperton.

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

Why choose Mr Mastic in Alperton

  • 12-month guarantee on every job
  • Old sealant always removed completely
  • Sanitary silicone with an anti-fungal additive in wet areas
  • ARBOMaster approved applicator

Alperton questions

I let a flat near Wembley Central station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.

Can parking be tricky for a visit in Alperton?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status.

Are you fully insured?

Yes, we’re fully insured.

Can you quote for more than one area?

Yes. Just list everything you need and we’ll quote it together.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints.

Can you just seal over the old silicone?

No. Sealing over the top looks fine for a few weeks, then lifts. We remove the old bead completely before resealing.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.

Bathrooms and kitchens in Alperton

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.

Homes close to St James Church Alperton include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as Alperton Community 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.

When something else is needed

A few problems are outside what sealant work can do:

  • Damage behind the tiles that needs a tiler
  • Leaks from a shower valve, waste or pipework (a plumber’s job)
  • A bath or tray that moves because it isn’t properly supported

Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Joints and surfaces we work on

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

Do you need bathroom resealing in Alperton?

Plenty of failed sealant has been laid over the top of older sealant. New silicone will not bond to old silicone, so it lifts, lets water in and traps mould underneath.

These are the problems we are asked about most:

  • New sealant laid over old sealant that is now lifting
  • Smears of silicone across the tiles
  • Gaps between the worktop and the wall
  • Leaks into the floor or ceiling below

Alperton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How to choose a mastic man

DIY versus a professional finish

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
