FAQs for North Kelvinside
Who arranges sealant work on the shared parts of a tenement in North Kelvinside?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Do you cover North Kelvinside for sand mastic?
Yes. Our work covers the whole of Scotland, and North Kelvinside is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages to suit the site.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
About our sand mastic in North Kelvinside
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on brick reveals, tenement windows and sash and case windows, and the jobs we see most are gaps round a timber door in stone or brick and mastic dropping out of the joint.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. Whether you are in a tenement flat or a house in North Kelvinside, the joint between frame and wall is what keeps the weather out.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Take care around the mastic when scraping paint
- Do not run silicone over sand mastic
- Find out about consent before window work on a listed home
- Have rotten timber repaired before new mastic goes in
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.

What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes anything from a few hours to a full day, depending on how many windows. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In North Kelvinside, it helps to know the floor, the door entry arrangements and the nearest parking.

- Old, loose mastic is raked out and the joint cleaned.

Windows and doors in North Kelvinside
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. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Windows generally belong to the flat, but the title deeds have the final say.
Managing a site like College of Piping? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Possilpark & Parkhouse station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Historic houses such as Tenement House, about 0.9 miles south-east, show how far back building around North Kelvinside goes, and older homes nearby need a sealant that suits their walls.

What the job involves on each surface
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
