Sand Mastic in Falkirk
We cover Falkirk for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Cement or filler used on old window joints that has cracked
- Open joints round the window box
- A silicone bead on a sash window that spoils the look
The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints. Parking around Falkirk is rarely difficult, though older streets in the centre can be tight. If you’re in a flat with a shared stair or a door entry system, let us know when you book.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- 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.
Preparing for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

Advice
Sand mastic for homes and businesses in Falkirk
Across Falkirk, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on stone surrounds, tenement windows and brick reveals, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and gaps between timber frames and stone or brick.
In a town like Falkirk, stone-built older streets usually sit alongside harled houses and newer estates, and windows range from older sash and case to modern uPVC. The sealant has to suit both the frame and the wall it sits in.
There’s a 12-month guarantee on every job, large or small.

Common questions in Falkirk
Do you cover Falkirk for sand mastic?
Yes. Our work covers the whole of Scotland, and Falkirk is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
What guarantee comes with sand mastic in Falkirk?
All our work, in Falkirk and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can old silicone round a sash window be swapped for sand mastic?
Generally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Sand mastic in Falkirk: local notes
Sash and case windows are common in older Scottish homes, 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 failed outside joints work against that.
For an older house near a landmark such as St. Francis Xavier's Roman Catholic 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 Comely Park School, larger buildings have plenty of frames, and the mastic around each one ages.

- Mastic dropping out of the joint
- Draughty sash windows at the surround
- Tired mastic found when preparing windows for paint
- Open joints round the window box
For landlords with property near Falkirk Grahamston station, any sash windows need sound mastic to keep draughts and rain out.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
