About our sand mastic in Barrowfield
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with cement or filler used on old window joints that has cracked and tired mastic found when preparing windows for paint, across period & listed homes, timber door frames and tenement windows.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. In Barrowfield, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
Our work is backed for twelve months, in Barrowfield and everywhere else we cover.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Clear gutters so water doesn’t pour onto the windows
- Inspect the joints round the windows every year or so
- Go gently near the mastic when preparing windows
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
The process
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for a single window, longer for several in most cases. In a city area like Barrowfield, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Common questions in Barrowfield
Who arranges sealant work on the shared parts of a tenement in Barrowfield?
It normally 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.
Can you help a landlord with a rental near Duke Street station?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Do you come to Barrowfield?
Yes. We work in Barrowfield. To book, drop us a line at info@mrmastic.co.uk.
Is it possible to take out silicone and use sand mastic instead?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
How long will you be here?
Most jobs take a few hours for a single window, longer for several. Your quote will say how long we expect yours to take.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
What does sand mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
Windows and doors in Barrowfield
Glasgow’s tenements are largely red and blond sandstone, and porous sandstone needs a sealant that won’t mark it. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Who owns the windows depends on the title deeds.
If you let a flat or house near Duke Street station, any sash windows need sound mastic to keep draughts and rain out. Schools such as St Mungo's Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Historic houses such as Provand's Lordship, about 1.2 miles north-west, show how far back building around Barrowfield goes.
