How we handle sand mastic in Kelvinbridge
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. Common call-outs are for patchy fillers round a sash window and cracked mastic round a front door frame, across period & listed homes, brick reveals and stone surrounds.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you are in a tenement flat or a house in Kelvinbridge, the joint between frame and wall is what keeps the weather out.
Whatever the size of the job, you get the same one-year guarantee.

Do you need sand mastic in Kelvinbridge?
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
Keep an eye out for these signs:
- Failed mastic on an exposed elevation
- Silicone on a period window that looks wrong
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
Letting a property close to Charing Cross (Glasgow) station? Then any sash windows need sound mastic to keep draughts and rain out.
Questions to ask before booking
- When the joint can take water or movement
- Is the old sealant removed completely?
- How the colour is chosen
- Which sealant they’ll use, and why
Windows and doors in Kelvinbridge
Historic houses like Tenement House (about 0.6 miles south-east) are a reminder that the area around Kelvinbridge has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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 College of Piping, the mastic around its windows and doors needs looking after like any other building’s. Homes close to St Vincent Street Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions from Kelvinbridge
I let a flat near Charing Cross (Glasgow) station. Can you help?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Kelvinbridge?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Can old silicone round a sash window be swapped for sand mastic?
Normally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
How long does the job take?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll tell you how long to expect.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
What does sand mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Should I use sand mastic or silicone?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Kelvinbridge, damp can travel a long way before it shows.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

DIY versus a professional finish
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Kelvinbridge, tell us the floor, how the door entry system works and where we can park nearby.
