Leave it or put it right?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. In an older home around Balloch, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint usually makes the job bigger, not smaller, 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.

Sand mastic in Balloch
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. We work on tenement windows, brick reveals and sash and case windows, and the jobs we see most are draughty sash windows at the surround and window mastic to renew ahead of painting.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
All of our work is guaranteed for twelve months.

Balloch questions
Is Balloch within the area you cover?
Yes, Balloch is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Balloch for sand mastic?
Yes, Balloch is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours per window, depending on the condition of the joints. Somewhere like Balloch may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Move anything stored near the joints
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

What else we do in Balloch
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Common problems we fix in Balloch
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
It’s worth asking for a quote if you see:
- Draughts and rain around sash boxes
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Old cement repairs round a window that have failed
If you look after a building such as Our Lady's High, its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Make sure water runs off the sill
- Renew mastic before redecorating the windows
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
When something else is needed
We’ll always be straight with you, so here’s what new sealant will not do:
- Sashes that rattle, stick or won’t open
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

Surface by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Frames and glazing around Balloch
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For landlords with property near Croy station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
