Sand mastic in Niddrie Mains
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. We are often asked to deal with old sand mastic that has cracked, crumbled or fallen out and mastic round period door frames that has failed, across tenement windows, timber door frames and sash and case windows.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Niddrie Mains, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
Whatever the size of the job, you get the same one-year guarantee.

What we are called out for in Niddrie Mains
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Any of these means the joints need attention:
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
- Old sand mastic that has cracked, crumbled or fallen out
If you let a flat or house near Brunstane station, any sash windows need sound mastic to keep draughts and rain out.
Before booking anyone

- Is the old sealant removed completely?
- When the joint can take water or movement
- Which colour the sealant will be
Sand mastic in Niddrie Mains: local notes
Niddrie Mains is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Castlebrae Community High School, its window and door frames need their mastic kept sound, just like a home’s. Whitefoord House, about 2.4 miles north-west, is one of the historic houses in the wider area around Niddrie Mains, and older homes nearby need a sealant that suits their walls.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Niddrie Mains: your questions answered
Does living near the coast affect sand mastic in Niddrie Mains?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
How is work on the outside of a tenement in Niddrie Mains normally arranged?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. 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.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Why deal with it now?
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Private landlords in Niddrie Mains must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Look over the window mastic once a year
- Ask a joiner to look at soft timber first
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
