Sand mastic in Granton
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include a silicone bead on a sash window that spoils the look and gaps between timber frames and stone or brick, on tenement windows, sash and case windows and stone surrounds.
Granton 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 won’t mark or attack it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours per window, depending on the condition of the joints from start to finish. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Granton, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

What else we do in Granton
Your questions about sand mastic in Granton
Does living near the coast affect sand mastic in Granton?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
How do repairs to the shared parts of a tenement in Granton get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Do you cover Granton?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Landlord and commercial work in Granton
For anyone letting property in or around Granton, several properties can be quoted together. Just tell us the addresses and what each one needs.
Letting agents and landlords in Granton can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
Why it’s worth doing now in Granton
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. Wind-driven rain gets into any failed joint on the outside of a city building, and in Granton, damp can spread through stone and plaster before anyone sees it.

When it isn’t the sealant
To be straight with you, some problems need a different trade:

- Cracked or broken glass
- Crumbling stone or brickwork round the window

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How to look after the new joints
So the new joints stay in good condition:
- Make sure water runs off the sill
- Get any rot dealt with first
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
What sand mastic looks like in Granton
Granton 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. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Windows normally belong to the flat, but the title deeds have the final say.
Managing a site like Ainslie Park High School? Then larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Granton Congregational Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Haymarket station, any sash windows need sound mastic to keep draughts and rain out.
