Sand mastic in Townhead
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. Common call-outs are for patchy fillers round a sash window and weathered mastic on the most exposed windows, on period & listed homes, stone surrounds and brick reveals.
Townhead is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, which usually means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Our work is backed for twelve months.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. For a tenement in Townhead, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention any tricky access
- Tell us about any water getting in
- Keep pets and children clear of the area while we work

Signs you need sand mastic in Townhead
Rain on the window surround works into any crack and pushes it out. Exposed elevations normally fail first.
People usually contact us after spotting one of these:
- Window mastic to renew ahead of painting
- Open joints round the window box
- Weathered mastic on the most exposed windows
- Wind and rain getting in round a sash window
Schools such as Allan Glen's School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Townhead questions
Can you help a landlord with a rental near Glasgow Queen Street station?
Yes, rental work is part of what we do. Just email us at 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 Townhead?
Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Where do you work from?
Mr Mastic is based in Crawley. We cover Townhead and the rest of Glasgow.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Different surfaces, different methods
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Why deal with it now?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In a tenement flat in Townhead, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Aftercare tips
So the new joints stay in good condition:
- Don’t paint over the new mastic
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Honest limits
A few problems are outside what sealant work can do:
- Whether work needs listed building consent
- Putty and glazing repairs
- Damaged stone surrounds
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
