About our sand mastic in Greenbank
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on period & listed homes, tenement windows and timber door frames, and the jobs we see most are tired mastic found when preparing windows for paint and cement or filler used on old window joints that has cracked.
Greenbank is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Big or small, it’s backed by our one-year guarantee in Greenbank and across Edinburgh.

Can you do sand mastic in Greenbank?

Can I do it myself?

Can you match the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before any work starts.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Common problems we fix in Greenbank

Most people get in touch after spotting something like this:
- Draughty sash windows at the surround
- Open joints round the window box
- A silicone bead on a sash window that spoils the look
- Mastic round period door frames that has failed
If you let a flat or house near Slateford station, any sash windows need sound mastic to keep draughts and rain out.

Greenbank homes and the weather
With historic houses such as Whitefoord House (about 3 miles north-east) nearby, there’s older building stock in the area around Greenbank as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Whitefoord House, about 3 miles north-east, is one of the historic houses in the wider area around Greenbank. For site and facilities teams at buildings such as Firrhill High School, its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
Timber door frames
Round a period front door, sand mastic gives the right look.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Can I do it myself?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The process
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job normally takes a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. In a city area like Greenbank, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- We look at the surrounds with you and agree the joints to renew.
