When it isn’t the sealant

To be straight with you, there are a few things sealant won’t fix:

  • Sashes that rattle, stick or won’t open
  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Putty and glazing repairs

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

How we handle sand mastic in Painter's Forstal

Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Typical jobs include mastic round period door frames that has failed and failed mastic on an exposed elevation, across timber door frames, stone surrounds and tenement windows.

Homes in small places like Painter's Forstal often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

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

Keeping the joints in good condition

So the new joints stay in good condition:

  • Sort the mastic before the decorators arrive
  • Check with your local planning authority if your home is listed
  • Have rotten timber repaired before new mastic goes in
  • Ask us before painting near the mastic

Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.

Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

What we’re called out for in Painter's Forstal

Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.

Most people get in touch after spotting one of these:

  • Draughty sash windows at the surround
  • Weathered mastic on the most exposed windows
  • Old sand mastic that has cracked, crumbled or fallen out
  • Gaps where the frame meets the masonry

If you let a flat or house near Faversham station, any sash windows need sound mastic to keep draughts and rain out.

Windows and doors in Painter's Forstal

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Belmont House and Gardens (about 1.8 miles south) nearby, there’s older building stock in the area around Painter's Forstal as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

If you live in an older home near Church of St Peter and St Paul, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Ospringe Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?

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. All the old material has to come out first.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What affects the cost of sand mastic

Your quote is based on your job. We look at:
