About our new build mastic in Wineham

Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. We work on skirting & floors, bathrooms & en suites and kitchens, and people most often call us about messy sealant that spoils new finishes and joints pulling apart as timber shrinks.

For a small place like Wineham, the journey and access are planned in advance, and the work itself is the same as on any site.

A one-year guarantee comes with the work, just as it does everywhere we cover.

When it is not the sealant

Some problems need a builder, plumber or other trade rather than us:

  • Your warranty claim itself, which is between you and the builder
  • A tray or bath that is not properly supported, until it’s fixed
  • Damaged fittings that need replacing

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

Surfaces we seal

  • Windows & doors
  • Show homes
  • Bathrooms & en suites
  • Kitchens

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Wineham: your questions answered

Do you cover Wineham for new build mastic?

Yes. Our work covers London and the South East, and Wineham is part of that. Just phone 0345 464 0079 or email us with a few details of the job.

Is there a guarantee on new build mastic in Wineham?

Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

How long does the job take?

A typical job takes anything from a few hours to several days, depending on the number of plots. Your quote will say how long we expect yours to take.

What colour sealant will you use?

The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.

What do you need from me for a quote?

Let us know what needs doing and where, plus pictures if you have them. If we need more, we will ask.

Where is Mr Mastic based?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Are you fully insured?

Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.

When to call us in Wineham

If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry first.

Keep an eye out for these signs:

  • Kitchen sealant that has pulled off the wall
  • Smeared, uneven beads picked up at snagging
  • Gaps between new skirting and floors
  • Sealant that never bonded to the surface

Whether the job is in Wineham itself or nearby, the right material for each joint matters as much as a neat finish.

Our hiring checklist

Looking after it afterwards

A little care helps the new joints last. We recommend:

  • Clean sealant with mild detergent, not abrasives
  • Use the extractor fan every time you shower
  • Look at the sealant regularly in the first couple of years
  • Put sealant faults on your snagging list early

Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.

Different surfaces, different methods

Show homes

In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.

Windows and doors

A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.

Landlords, agents and businesses in Wineham

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

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

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

The process

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere like Wineham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. We cut out every bit of the failed or messy sealant.
  3. Surfaces are cleaned of building dust and primed where needed.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. We check every joint and tell you how long each needs to cure.

Preparing for the visit

  • Tell us about any water getting in
  • Plan for the work area to be out of bounds to pets and children
  • Clear the area around the work
