Your questions about sand mastic in Blochairn
Do you cover Blochairn for sand mastic?
Yes. We work across all of Scotland, and Blochairn is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Blochairn?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you work for landlords and businesses?
Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.
Sand mastic in Blochairn
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We work on timber door frames, sash and case windows and tenement windows, and the jobs we see most are mastic dropping out of the joint and old cement repairs round a window that have failed.
Blochairn is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
Each job carries a 12-month guarantee, large or small.

When it isn’t the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Crumbling stone or brickwork round the window
- Sashes that need overhauling
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before booking.
Joints and surfaces we work on
- Brick reveals
- Sash and case windows
- Tenement windows
- Period & listed homes
- Timber door frames
- Stone surrounds
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Renew mastic before redecorating the windows
- Keep sills and gutters clear so water drains away
- Don’t paint over the new mastic
- Ask a joiner to look at soft timber first
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

When to call us in Blochairn
Water gets into small cracks in the mastic and loosens it further. Exposed elevations normally fail first.
Any of these means the joints need attention:
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
- Mastic that needs renewing before redecorating
- Weathered mastic on the most exposed windows
For landlords with property near Alexandra Parade station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

- How the surfaces are prepared before sealing
- Are they insured?
- Is the old sealant removed completely?
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the amount of work. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Blochairn, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

What sand mastic looks like in Blochairn
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Managing a site like St. Roch's Secondary School? Then the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Our Lady of Good Counsel Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Blochairn is about 2 miles north-east of Glasgow, in Glasgow. Jobs in Blochairn get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Across Glasgow, we cover 183 places, Blochairn among them.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
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 that we can handle for you.
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. 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.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

How the job changes by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
