Frames and glazing around Colinton
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you live in an older home near Colinton Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Kingsknowe station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

How we handle sand mastic in Colinton
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on tenement windows, brick reveals and timber door frames, and the jobs we see most are draughty sash windows at the surround and open joints round the window box.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. For a flat in Colinton, access is the first thing to plan.
Your job is guaranteed for a year, as with all our work.

Do you need sand mastic in Colinton?
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint and we normally remove them.
It’s worth asking for a quote if you see:
- Wind and rain getting in round a sash window
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
- Old sand mastic that has cracked, crumbled or fallen out
If you look after a building such as Army School of Bagpipe Music and Highland Drumming, larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- Are they insured?
- How long to leave it before use
- Is the old sealant removed completely?
- Whether you can choose the colour
Keeping the joints in good condition
After the cure time, these simple habits help:
- Ask us before painting near the mastic
- Get any rot dealt with first
- Avoid heavy scraping on the mastic joint
- Inspect the joints round the windows every year or so
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Colinton questions
Is Colinton in your area for sand mastic?
Yes, Colinton is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Can you help a landlord with a rental near Kingsknowe station?
Yes, we work for letting agents and landlords. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We’ll tell you when we quote.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Should I use sand mastic or silicone?
That depends on your windows. Period windows in stone or brick normally suit sand mastic and newer frames normally get a flexible sealant.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.

What happens on the day
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a single window, longer for several for a typical job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Colinton, tell us the floor, how the door entry system works and where we can park nearby.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
