About our sand mastic in Warriston
Across Warriston, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have old sand mastic that has cracked, crumbled or fallen out and gaps between timber frames and stone or brick, we can help, on timber door frames, stone surrounds and sash and case windows alike.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Warriston.
A one-year guarantee comes as standard.

What sand mastic looks like in Warriston
Warriston 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. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. For listed homes and conservation areas, check with the council before changing how windows or walls look.
Letting a property close to Edinburgh Waverley station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Drummond Community High School, its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Warriston questions
Does living near the coast affect sand mastic in Warriston?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Who arranges sealant work on the shared parts of a tenement in Warriston?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Are you fully insured?
Yes. We are fully insured for domestic and commercial work.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What affects the cost of sand mastic

- The number of rooms or windows
- Any mould that needs treating

- When we can work, for business premises
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Whether it’s a home or a business
- The address or postcode of the job
- Whether it has been sealed before
- How we’d reach the joints

What we’re called out for in Warriston
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
People normally contact us when they notice something like this:
- Open joints round the window box
- Weathered mastic on the most exposed windows
- Draughty sash windows at the surround
- Crumbling sand mastic round a window
In the older streets around St Serf's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Whether they’re fully insured
- How hidden problems are handled
- What guarantee comes with the work
- Who does the work, and how experienced they are
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Warriston, 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.
- The surface is finished to suit the stone or brick.
