Sand mastic for sash & case windows in Midstocket, Aberdeen
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for Midstocket, backed by a one-year guarantee. Call for a quick quote.
- Gaps where the frame meets the masonry
- Wind and rain getting in round a sash window
- Window mastic to renew ahead of painting
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask the planning authority about consent for listed or conservation-area homes
- Do not run silicone over sand mastic
- Avoid heavy scraping on the mastic joint
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
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 we handle sand mastic in Midstocket
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. If you are dealing with crumbling sand mastic round a window and cement or filler used on old window joints that has cracked, we can put it right.
In and around a place like Midstocket, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What sand mastic looks like in Midstocket
Midstocket is close to 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. Aberdeen’s nickname, the Granite City, comes from its stone buildings, and sealing against granite needs clean, sound edges and a sealant that suits stone.
Letting a property close to Aberdeen station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as St Ninian's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
Midstocket is about 1 mile south-west of Aberdeen, in Aberdeen. Midstocket gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Midstocket is one of 63 places in Aberdeen we cover for sand mastic.
