About our sand mastic in Ardheisker

Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We work on sash and case windows, stone surrounds and timber door frames, and common reasons people get in touch are patchy fillers round a sash window and mastic worn away on windows facing the weather.

Outdoor sealant needs a dry surface, so window work around Ardheisker is planned around the weather. Let us know about access to every frame, including any upstairs.

Your job is guaranteed for a year, as with all our work.

Why it’s worth doing now in Ardheisker

New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.

Doing several joints on one visit is normally more efficient than separate visits. We will send you a clear quote for the lot.

The process

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several, and the area is left clean. Outdoor work around Ardheisker depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Getting ready for the visit

  • Mention any parking rules near the property
  • Keep pets and children clear of the area while we work
  • Where the joints are inside, avoid wetting them before we arrive

What sand mastic looks like in Ardheisker

Ardheisker is within about 1 mile of 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

In and around Ardheisker, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. For jobs in and around Ardheisker, choosing the right material for each joint is as important as a tidy finish.

Ardheisker is in Na h-Eileanan Siar. Whether you are in the middle of Ardheisker or further out, sand mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Ardheisker is one of 87 towns and villages in Na h-Eileanan Siar where we work for sand mastic.

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Ask a joiner to look at soft timber first
  • Don’t run silicone over sand mastic
  • Plan mastic work ahead of painting
  • Ask the planning authority about consent for listed or conservation-area homes

Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

Different surfaces, different methods

Sash and case windows

The mastic round a sash window is on show so we finish it carefully.

Stone surrounds

The stone is treated with care when the old mastic comes out.
