Sand mastic in Caldercruix, done properly

On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. We work on period & listed homes, stone surrounds and sash and case windows, and common reasons people get in touch are cracked mastic round a front door frame and draughts and rain around sash boxes.

Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

What affects the cost of sand mastic

We do not publish a price list, because no two jobs are the same. What we look at:

  • The type of sealant required
  • How much old sealant there is and how hard it is to remove
  • Any mould that needs treating
  • When we can work, for business premises

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Helping us quote

To make quoting easier, please include:

  • Pictures of the joints, sent by email
  • Access, such as stairs, a lift or height
  • Whether it has been sealed before
  • What’s wrong with the joints now

Every job is quoted individually, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details.

What sealant work cannot fix

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

  • Crumbling stone or brickwork round the window
  • Whether work needs listed building consent
  • Rotten sashes, sills or window boxes (a joiner’s job)

If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.

What we seal

  • Stone surrounds
  • Period & listed homes
  • Timber door frames
  • Tenement windows
  • Brick reveals
  • Sash and case windows

Leave it or put it right?

Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Caldercruix, water from a failed joint in an older stone home can soak into timber and plaster.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Keeping the joints in good condition

Simple care keeps the joints in good condition. Our advice:

  • Check the mastic when you check the paintwork
  • Find out about consent before window work on a listed home
  • Keep modern sealant off the mastic
  • Clear gutters so water does not pour onto the windows

When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.

It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

Windows and doors in Caldercruix

Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

For an older house near a landmark such as Longriggend And Meadowfield Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Caldercruix station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Should I try it myself first?

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.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
