Sand mastic for homes and businesses in Boat of Garten
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with patchy fillers round a sash window and wind and rain getting in round a sash window, we can help, on sash and case windows, brick reveals and period & listed homes alike.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Each job carries a 12-month guarantee, large or small.

Landlord and commercial work in Boat of Garten
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
How much does sand mastic cost in Boat of Garten?

How we quote for sand mastic
We do not publish a price list. What we look at:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove

- The size of the job
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it’s a home or a business
- Where the property is
- What’s wrong with the joints now
- Whether it has been sealed before
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
- Don’t paint over the new mastic
- Avoid patching sand mastic with silicone
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.

What sand mastic looks like in Boat of Garten
Many older homes in Scotland have sash and case windows, 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.
Around Boat of Garten, as everywhere, sand mastic is only as good as the preparation behind it. For landlords with property near Carrbridge station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
