Sand mastic in Kingarth

Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. We’re often asked to deal with old sand mastic that has cracked, crumbled or fallen out and patchy fillers round a sash window, across stone surrounds, sash and case windows and timber door frames.

Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What we do, step by step

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. Somewhere like Kingarth may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

Preparing for the visit

  • Keep children and pets away from the work area
  • Let us know if you’ve seen damp or leaks
  • For indoor joints, keep the area dry beforehand if you can

  • Gaps between timber frames and stone or brick
  • Draughty sash windows at the surround

10 questions to ask before booking

Frames and glazing around Kingarth

Kingarth is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Mount Stuart House (about 2.1 miles north) are a reminder that the area around Kingarth has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Historic houses such as Mount Stuart House, about 2.1 miles north, show how far back building around Kingarth goes, and older homes nearby need a sealant that suits their walls.

Leave it or put it right?

Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Landlords, agents and businesses in Kingarth

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Should I try it myself first?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Looking after it afterwards

So the new joints stay in good condition:

  • Find out about consent before window work on a listed home
  • Plan mastic work ahead of painting
  • Don’t run silicone over sand mastic
  • Look over the window mastic once a year

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

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
