Advice
Sand mastic for homes and businesses in Old Balornock
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. If you have mastic that needs renewing before redecorating and cement or filler used on old window joints that has cracked, we can help, whatever the surface.
Old Balornock is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

FAQs for Old Balornock
Is Old Balornock in your area for sand mastic?
Yes, Old Balornock is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Can you help a landlord with a rental near Barnhill station?
Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours for a single window, longer for several. We will tell you when we quote.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
What we are called out for in Old Balornock
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Keep an eye out for these signs:
- Mastic that needs renewing before redecorating
- Draughts and rain around sash boxes
- Mastic worn away on windows facing the weather
- Gaps where the frame meets the masonry
Letting a property close to Barnhill station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.
What to look for in a quote
- Whether you can choose the colour
- How much experience the applicator has
- Whether all the old sealant comes out first
- When the joint can take water or movement
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Why deal with it now?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. In a tenement flat in Old Balornock, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Frames and glazing around Old Balornock
Old Balornock 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 failed outside joints work against that.
If you look after a building such as St. Roch's Secondary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Our Lady of Good Counsel Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check with your local planning authority if your home is listed
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
- Inspect the joints round the windows every year or so
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
