Sand mastic for homes and businesses in Gartcosh
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you are dealing with window mastic to renew ahead of painting and gaps where the frame meets the masonry, we can help, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
You’re covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Frames and glazing around Gartcosh
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, often pointed into the wall with traditional sand mastic.
If you look after a building such as Chryston High School, the mastic around its windows and doors needs looking after like any other building’s.

Common questions in Gartcosh
Is Gartcosh in your area for sand mastic?
Yes. We work across all of Scotland, and Gartcosh is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Will you come out to Gartcosh?
Yes, we do. 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.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.
What we are called out for in Gartcosh
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
The most common problems we see are:
- Old cement repairs round a window that have failed
- A silicone bead on a sash window that spoils the look
- Weathered mastic on the most exposed windows
- Wind and rain getting in round a sash window
Letting a property close to Gartcosh station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
What to look for in a quote
- Is VAT in the price?
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
- What product goes in the joint
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
What affects the cost of sand mastic
You will get a clear quote before any work starts. It takes into account:
- The product the joint needs
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- The size of the job
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
What to tell us when you ask for a quote:
- If someone has resealed it before
- How we’d reach the joints
- Roughly how big the job is
- A few pictures by email, if you can
If you’re in Gartcosh and need sand mastic, email us at info@mrmastic.co.uk. Tell us what the problem is and where, and we’ll agree the price before any work begins.
How it works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. For a place like Gartcosh, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Around Gartcosh, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

Aftercare tips
Looking after new joints is easy:
- Plan mastic work ahead of painting
- Inspect the joints round the windows every year or so
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
Honest limits
We won’t take on work that will not last, so here’s what sealant cannot put right:
