How we handle sand mastic in Westrigg
Burnt sand mastic is a traditional material 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 period & listed homes, sash and case windows and brick reveals, and people most often call us about crumbling sand mastic round a window and modern sealant on a period surround.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Our work is backed for twelve months.

DIY versus a professional finish
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.
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 sand mastic looks like in Westrigg
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.
Letting a property close to Blackridge station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Crumbling stone or brickwork round the window
- Whether work needs listed building consent
- Timber that has rotted
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Sash and case windows
- Stone surrounds
- Brick reveals
- Tenement windows
- Timber door frames
- Period & listed homes
Why deal with it now?
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. In a place like Westrigg, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- We leave the area clean and tidy
- Fully insured
- Old sealant always removed completely
- Domestic, commercial and hotel work

How we quote for sand mastic
For a quick quote, just ask. The main things that affect it are:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- The size of the job
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Where the property is
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- The type of property
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
Common questions in Westrigg
Will you come out to Westrigg?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.

Do you have insurance?
Yes, we are fully insured for every job we do.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Common problems we fix in Westrigg
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
It’s worth asking for a quote if you see:
- Mastic round period door frames that has failed
- Mastic worn away on windows facing the weather
- Gaps between timber frames and stone or brick
- Old sand mastic that has cracked, crumbled or fallen out
For site and facilities teams at buildings such as Armadale Academy, the mastic around its windows and doors needs looking after like any other building’s.
