Glenlomond Sand Mastic
Window and door surrounds in Glenlomond need attention? We cut out the old, prepare the joints and apply the right sealant.

- Mastic that needs renewing before redecorating
Sand mastic in Glenlomond
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. Typical jobs include gaps round a timber door in stone or brick and open joints round the window box, on timber door frames, sash and case windows and tenement windows.
Mastic can only go onto a dry joint, so outside work in Glenlomond depends on the weather. Let us know about access to every frame, including any upstairs.
Every job is covered by our one-year guarantee, wherever you are in Perth and Kinross.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. Outdoor work around Glenlomond depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit

Related advice
Leave it or put it right?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Signs you need sand mastic in Glenlomond
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
Common reasons people contact us include:
- Wind and rain getting in round a sash window
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
- Open joints round the window box
Homes close to Easter Balgedie church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What to look for in a quote
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
- What the quote includes, VAT included or not
- What happens if they find a problem under the old sealant
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Renew mastic before redecorating the windows
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Glenlomond: your questions answered
Do you cover Glenlomond for sand mastic?
Yes, Glenlomond is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Do you cover smaller places like Glenlomond?
Yes, Glenlomond is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long does sand mastic take to harden?
Not right away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
Frames and glazing around Glenlomond
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
