Questions from Wierton

Can you do sand mastic in Wierton?

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

Is Wierton within the area you cover?

Yes, Wierton is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Is it possible to paint over sand mastic?

Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.

How long does sand mastic take to harden?

Not straight away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.

How long does sand mastic take?

Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.

Sand mastic in Wierton, done properly

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We work on sash and case windows, stone surrounds and brick reveals, and people most often call us about a silicone bead on a sash window that spoils the look and draughty sash windows at the surround.

Mastic can only go onto a dry, clean joint, so window work in Wierton is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

Whatever the size of the job, it’s backed by our 12-month guarantee in Wierton and across Kent.

How the visit works

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours for a single window, longer for several. In a small place like Wierton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check the window surrounds and agree which joints need renewing.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. We pack any deep gaps so the mastic sits at the right depth.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. The finish is dressed so it sits neatly against the stone or brick.

Before we arrive

  • Clear the area around the work
  • For business premises, tell us about site rules or sign-in
  • Mention any tricky access

Wierton homes and the weather

With historic houses such as Stoneacre (about 2.5 miles north-east) nearby, there’s older building stock in the area around Wierton as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.

Letting a property close to Staplehurst station? Then any sash windows need sound mastic to keep draughts and rain out. In the older streets around Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Looking after it afterwards

Looking after new joints is easy:

  • Avoid patching sand mastic with silicone
  • Ask a joiner to look at soft timber first
  • Make sure water runs off the sill
  • Find out about consent before window work on a listed home

Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.

Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

When to call us in Wierton

Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.

Most people get in touch after spotting something like this:

  • Old cement repairs round a window that have failed
  • Mastic that needs renewing before redecorating
  • A silicone bead on a sash window that spoils the look
  • Weathered mastic on the most exposed windows

Schools such as Boughton Monchelsea Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Why deal with it now?

Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Around Wierton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What you pay reflects the work, not guesswork. That is why we ask about the job first.
