How we handle sand mastic in Blairdardie
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. Common call-outs are for wind and rain getting in round a sash window and gaps between timber frames and stone or brick, on brick reveals, stone surrounds and tenement windows.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. For a flat in Blairdardie, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
Big or small, you get the same 12-month guarantee.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sand mastic in Blairdardie: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. Windows normally belong to the flat, but the title deeds have the final say.
For an older house near a landmark such as St David's Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Knightswood Secondary School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Drumchapel station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

What affects the quote in Blairdardie
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- Mould in or behind the old joints
- The amount of work
- Which sealant suits the joint
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
To make quoting easier, please include:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
Want a quote for sand mastic? Please send an email to info@mrmastic.co.uk with a few details. We’ll explain what we’d do and give you a clear quote before we start.
Why it’s worth doing now in Blairdardie
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Blairdardie, damp can travel a long way before it shows.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

What we cannot put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Sashes that need overhauling
- Crumbling stone or brickwork round the window
- Whether work needs listed building consent
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Brick reveals
- Tenement windows
- Timber door frames
- Stone surrounds
- Sash and case windows
- Period & listed homes
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several and we leave things clean and tidy. Inside a flat in Blairdardie, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
Ask for a quote
Every job is quoted individually, so the first step is telling us about yours. Just drop us a line at info@mrmastic.co.uk with the details and send pictures if you have them.

Looking after it afterwards
So the new joints stay in good condition:
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
- Don’t run silicone over sand mastic
- Find out about consent before window work on a listed home
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
