Sand mastic for sash & case windows in Shillford, East Renfrewshire
Our applicators work in Shillford 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.
- Mastic worn away on windows facing the weather
- Window mastic to renew ahead of painting
- A silicone bead on a sash window that spoils the look
What happens if it’s left?
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- Anti-fungal sanitary silicone in wet areas
- A 12-month guarantee on all work
- Any old sealant cut out fully, not covered over
- Quality sealants from Arbo and Everbuild

About our sand mastic in Shillford
Across Shillford, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on period & listed homes, stone surrounds and tenement windows, and people most often call us about a silicone bead on a sash window that spoils the look and draughts and rain around sash boxes.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What else we do in Shillford
Sand mastic in Shillford: local notes
Shillford is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. 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.
For an older house near a landmark such as Caldwell Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Can I paint the new mastic?

What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Clear gutters so water doesn’t pour onto the windows
- Ask us before painting near the mastic
- Do not run silicone over sand mastic
- Inspect the joints round the windows every year or so
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Damaged stone surrounds
- Cracked or broken glass
- Timber that has rotted
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
