Sand mastic for sash & case windows in Warriston, Edinburgh
Our applicators work in Warriston on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
How we handle sand mastic in Warriston
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on timber door frames, brick reveals and sash and case windows, and the jobs we see most are mastic dropping out of the joint and failed mastic on an exposed elevation.
Mastic can only go onto a dry joint, so outside work in Warriston depends on the weather. Let us know about access to every frame, including any upstairs.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

What sand mastic looks like in Warriston
Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. For listed homes and conservation areas, check with the council before changing how windows or walls look. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Schools such as Currie High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Curriehill station, any sash windows need sound mastic to keep draughts and rain out.

Surface by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to a full day, depending on how many windows. For a place like Warriston, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- 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 is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Crumbling stone or brickwork round the window
- Cracked or broken glass
- Timber that has rotted
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

Warriston questions
I let a flat near Curriehill station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can you do sand mastic in Warriston?
Yes. Our work covers the whole of Scotland, and Warriston is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Landlords, agents and businesses in Warriston
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Signs you need sand mastic in Warriston
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they usually need raking out.
Any of these means the joints need attention:
- Mastic dropping out of the joint
- Draughty sash windows at the surround
- Window mastic to renew ahead of painting
- Cracked mastic round a front door frame
In the older streets around St Mary's Episcopal Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before you book anyone
- Whether they seal over old material or remove it
- How long the guarantee is
- What the quote includes, VAT included or not
- How hidden problems are handled
What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.
