Do you need sand mastic in Kelvindale?
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
It’s worth asking for a quote if you see:
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
If you look after a building such as Cleveden Secondary School, the mastic around its windows and doors needs looking after like any other building’s.

Sand mastic in Kelvindale
We work across Kelvindale renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on brick reveals, sash and case windows and timber door frames, and common reasons people get in touch are draughts and rain around sash boxes and mastic round period door frames that has failed.
Kelvindale 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.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Aftercare tips
To keep the joints looking good and working properly:
- Don’t paint over the new mastic
- Don’t run silicone over sand mastic
- Check the mastic when you check the paintwork
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

What happens if it’s left?
Before painting the windows, it pays to renew the mastic. 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.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us
- We leave the area clean and tidy
- Quality sealants from Arbo and Everbuild
- Any old sealant cut out fully, not covered over
- ARBOMaster approved applicator

Kelvindale homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.
For landlords with property near Kelvindale station, older sash windows in a rental need their mastic kept sound to keep the weather out. Homes close to St John's Renfield Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

The process
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Kelvindale, it helps to know the floor, the door entry arrangements and the nearest parking.

What else we do in Kelvindale
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Putty and glazing repairs
- Rotten sashes, sills or window boxes (a joiner’s job)
- Crumbling stone or brickwork round the window
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
Where we work in Kelvindale
- Sash and case windows
- Timber door frames
- Period & listed homes
- Tenement windows
- Stone surrounds
- Brick reveals
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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. All the old material has to come out first.
