How we handle sand mastic in Gordon
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on stone surrounds, tenement windows and brick reveals, and people most often call us about mastic round period door frames that has failed and crumbling sand mastic round a window.
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.
Your job is guaranteed for a year, as with all our work.

Do you need sand mastic in Gordon?
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Look out for these signs:
- Open joints round the window box
- Window mastic to renew ahead of painting
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
In and around Gordon, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What the job involves on each surface
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Why deal with it now?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Related advice
Gordon homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. 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.
If you live in an older home near East Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
