Sand mastic in Little Dunkeld, done properly
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on sash and case windows, period & listed homes and brick reveals, and the jobs we see most are modern sealant on a period surround and weathered mastic on the most exposed windows.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Each job carries a 12-month guarantee, large or small.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Sashes that rattle, stick or will not open

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Do not run silicone over sand mastic
- Sort the mastic before the decorators arrive
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Signs you need sand mastic in Little Dunkeld
Rain on the window surround works into any crack and loosens it further. Exposed elevations generally fail first.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic on the most exposed windows
- Window mastic to renew ahead of painting
- Cracked mastic round a front door frame
- Open joints round the window box
If you live in an older home near Little Dunkeld Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why act early in Little Dunkeld
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In an older home around Little Dunkeld, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
