Sand mastic in Carrick Knowe, done properly

Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include failed mastic on an exposed elevation and modern sealant on a period surround, across timber door frames, period & listed homes and stone surrounds.

Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. For a flat in Carrick Knowe, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.

Every job comes with a one-year guarantee, wherever you are in Edinburgh.

What we can’t put right

It helps to know what we cannot do too:

  • Cracked or broken glass
  • Masonry that needs repairing
  • Whether work needs listed building consent

If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.

Where we work in Carrick Knowe

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

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Check the mastic when you check the paintwork
  • Leave the new mastic unpainted
  • Sort the mastic before the decorators arrive
  • Go gently near the mastic when preparing windows

Make sure water drains away from the window surround. Constant wetting wears the mastic faster.

Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

DIY versus a professional finish

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Signs you need sand mastic in Carrick Knowe

Timber swells and shrinks with the weather. The movement cracks the mastic over time.

These are the problems we are asked about most:

  • Weathered mastic on the most exposed windows
  • Cement or filler used on old window joints that has cracked
  • Tired mastic found when preparing windows for paint
  • Wind and rain getting in round a sash window

If you live in an older home near St Anne's Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions to ask before you book

  • Whether they seal over old material or remove it
  • How the colour is chosen
  • Is VAT in the price?
  • Which sealant they’ll use, and why

What the job involves on each surface

Brick reveals

An open joint at a brick reveal lets weather in. Renewing the mastic closes it.

Sash and case windows

Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.

How the visit works

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Carrick Knowe, tell us the floor, how the door entry system works and where we can park nearby.

  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. Large voids are packed out first, so the mastic is not too thick.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The finish is dressed so it sits neatly against the stone or brick.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Let us know about earlier repairs to the joints
  • Move anything stored near the joints

Frames and glazing around Carrick Knowe

Carrick Knowe is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Caroline Park (about 3.4 miles north) are a reminder that the area around Carrick Knowe has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

If you look after a building such as Scotus Academy, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near South Gyle station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
