Sand mastic in Great Wakering, done properly

Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. If you have cracked mastic round a front door frame and crumbling sand mastic round a window, we can help, on timber door frames, sash and case windows and brick reveals alike.

In smaller places like Great Wakering, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.

Big or small, you get the same one-year guarantee.

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.

How to look after the new joints

After the cure time, these simple habits help:

  • Ask us before painting near the mastic
  • Take care around the mastic when scraping paint
  • Renew mastic before redecorating the windows
  • Don’t run silicone over sand mastic

Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.

Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

Why deal with it now?

Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Great Wakering, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. A visit to Great Wakering is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We look at the surrounds with you and agree the joints to renew.
  2. Old mastic and any loose material are raked out.
  3. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

Before we arrive

  • Clear items away from the joints we are working on
  • Mention any parking rules near the property
  • Try not to wet indoor joints just before the visit

Advice

What we’re called out for in Great Wakering

Water gets into small cracks in the mastic and pushes it out. Exposed elevations generally fail first.

Most people get in touch after spotting something like this:

  • Mastic worn away on windows facing the weather
  • Draughty sash windows at the surround
  • Patchy fillers round a sash window
  • Mastic round period door frames that has failed

For site and facilities teams at buildings such as Great Wakering Primary Academy, the mastic around its windows and doors needs looking after like any other building’s.

Frames and glazing around Great Wakering

Great Wakering is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For landlords with property near Shoeburyness station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
