Sand mastic in Moorepark
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you are dealing with modern sealant on a period surround and cement or filler used on old window joints that has cracked, we can help.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Moorepark, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
A one-year guarantee comes as standard, so you are covered after we have gone.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
- Do not run silicone over sand mastic
- Go gently near the mastic when preparing windows
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Parking in city streets around Moorepark can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules
- Move anything stored near the joints

Related advice
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Different surfaces, different methods
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.

What sand mastic looks like in Moorepark
Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that will not stain or attack it. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Rented homes near Dumbreck station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
