Sand mastic for homes and businesses in Hillhead
Across Hillhead, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have wind and rain getting in round a sash window and silicone on a period window that looks wrong, we can help, on tenement windows, sash and case windows and brick reveals alike.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. Access is the first thing to plan for a job in Hillhead, and in a tenement the outside of the building may be a shared repair.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Your questions about sand mastic in Hillhead
Can you help a landlord with a rental near Partick station?
Yes, landlords and agents are among the people we work for. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
How is work on the outside of a tenement in Hillhead generally arranged?
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.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
How long does the job take?
As a guide, most jobs take a few hours for a single window, longer for several. Bigger jobs take longer, and we will say how long yours will take.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
How long does sand mastic take to harden?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Do you offer different sealant colours?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.
What happens if it’s left?
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Honest limits
In fairness, some problems need a different trade:
- Crumbling stone or brickwork round the window
- Sash cords, weights and draught-proofing of the sashes
- Whether work needs listed building consent
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.
Surfaces we seal
- Tenement windows
- Sash and case windows
- Timber door frames
- Period & listed homes
- Brick reveals
- Stone surrounds
Can I do it myself?
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 a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not run silicone over sand mastic
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
- Ask the planning authority about consent for listed or conservation-area homes
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
What sand mastic looks like in Hillhead
Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that will not stain or attack it. With historic houses such as Tenement House (about 0.9 miles south-east) nearby, there’s older building stock in the area around Hillhead as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Hillhead High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Wellington Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we’re called out for in Hillhead
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between timber frames and stone or brick
- Gaps round a timber door in stone or brick
- Draughty sash windows at the surround
- Old cement repairs round a window that have failed
Letting a property close to Partick station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per window, depending on the condition of the joints. In a city area like Hillhead, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
