Advice
How we handle sand mastic in Duntocher
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We work on brick reveals, tenement windows and timber door frames, and common reasons people get in touch are window mastic to renew ahead of painting and draughts and rain around sash boxes.
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, so the mastic there works hard.
A one-year guarantee comes as standard.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
FAQs for Duntocher
Will you come out to Duntocher?
Yes, Duntocher is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Kilpatrick station?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
How much does sand mastic cost in Duntocher?
It depends on the job, so we quote each one individually. To get one, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply send an email to info@mrmastic.co.uk.
How to look after the new joints
Aftercare is simple:
- Inspect the joints round the windows every year or so
- Do not run silicone over sand mastic
- Ask us before painting near the mastic
- Clear gutters so water does not pour onto the windows
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
What sand mastic looks like in Duntocher
Duntocher is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Duntocher 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.
For site and facilities teams at buildings such as Clydebank High School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Kilpatrick station, older sash windows in a rental need their mastic kept sound to keep the weather out.
