About our sand mastic in Balloch
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you have patchy fillers round a sash window and silicone on a period window that looks wrong, we can put it right, on stone surrounds, sash and case windows and tenement windows alike.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Big or small, it’s backed by our one-year guarantee.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints. Outside jobs in Balloch need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed

Why deal with it now?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What sand mastic looks like in Balloch
Balloch is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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 failed outside joints work against that.
If you let a flat or house near Inverness Airport station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Barn Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Balloch is about 1 mile north-east of Cradlehall, in Highland.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Questions from Balloch
Do you work for landlords with property near Inverness Airport station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Is sand mastic in a coastal place like Balloch any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Check the mastic when you check the paintwork
- Don’t run silicone over sand mastic
- Leave the new mastic unpainted
- Check with your local planning authority if your home is listed
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
When to call us in Balloch
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Signs it’s time to call us include:
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
Managing a site like Culloden Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

- Stone surrounds

How the job changes by surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
