Frames and glazing around Forgandenny
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In the older streets around Forgandenny Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear gutters so water doesn’t pour onto the windows
- Inspect the joints round the windows every year or so
- Avoid patching sand mastic with silicone
- Don’t paint over the new mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Honest limits
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
- Sashes that rattle, stick or will not open
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.

When to call us in Forgandenny
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Crumbling sand mastic round a window
- Draughty sash windows at the surround
- Open joints round the window box
- Window mastic to renew ahead of painting
If you let a flat or house near Perth station, any sash windows need sound mastic to keep draughts and rain out.
