Sand mastic for sash & case windows in St Madoes, Perth and Kinross
Sand mastic for St Madoes, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
- Gaps between timber frames and stone or brick
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Ask a joiner to look at soft timber first
- Check with your local planning authority if your home is listed
- Plan mastic work ahead of painting
- Inspect the joints round the windows every year or so
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
How we handle sand mastic in St Madoes
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on brick reveals, tenement windows and timber door frames, and common reasons people get in touch are gaps between timber frames and stone or brick and old cement repairs round a window that have failed.
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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job generally takes a few hours for a single window, longer for several, and we explain the cure time before we leave. For a place like St Madoes, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Let us know about parking restrictions
- Mention any tricky access
- Clear items away from the joints we are working on

St Madoes homes and the weather
St Madoes 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 sound outside sealant is part of that.
In the older streets around St Madoes Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
