Sand mastic in Sanndabhaig
We work across Sanndabhaig renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you are dealing with silicone on a period window that looks wrong and cracked mastic round a front door frame, we can help.
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.
There’s a 12-month guarantee on every job, large or small.

The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints, and the area is left clean. Somewhere like Sanndabhaig may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit

What we are called out for in Sanndabhaig
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they normally need raking out.
Most people get in touch when they notice one of these:
- Mastic worn away on windows facing the weather
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
- Mastic round period door frames that has failed
Whether the job is in Sanndabhaig itself or nearby, the right material for each joint matters as much as a neat finish.

Frames and glazing around Sanndabhaig
Sanndabhaig 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. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Island weather, with its wind and salt spray, is tough on the mastic around older windows and doors.
In and around Sanndabhaig, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
