Sand mastic for sash & case windows in Anderston, Glasgow
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homes and businesses in Anderston and across Glasgow. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
- Gaps round a timber door in stone or brick
Looking after it afterwards
So the new joints stay in good condition:
- Get any rot dealt with first
- Leave the new mastic unpainted
- Look over the window mastic once a year
- Go gently near the mastic when preparing windows
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
About our sand mastic in Anderston
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Common call-outs are for mastic worn away on windows facing the weather and mastic dropping out of the joint, on period & listed homes, sash and case windows and timber door frames.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
Whatever the size of the job, you get the same 12-month guarantee in Anderston and across Glasgow.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Scottish rain finds any gap around a frame or wall joint, and in Anderston, damp can spread through stone and plaster before anyone sees it.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Anderston, tell us the floor, how the door entry system works and where we can park nearby.
- 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.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.

What affects the quote in Anderston
Every job gets its own quote. These are the things that affect it:
- How many areas need sealing
- How much there is to do
- The type of sealant required
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Roughly how big the job is
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
To get a quote, email us at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.
Anderston questions
Can you help a landlord with a rental near Charing Cross (Glasgow) station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
How do repairs to the shared parts of a tenement in Anderston get organised?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
Which products do you use?
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.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
How long does sand mastic take?
It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We will give you a better idea when we quote.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
What information do you need?
A short description and the location. We’ll ask anything else we need to know.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.

Sand mastic in Anderston: local notes
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Historic houses like Tenement House (about 0.1 miles north) are a reminder that the area around Anderston 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’s traditional sand mastic.
