Sand mastic in Earlston
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. If you have window mastic to renew ahead of painting and cracked mastic round a front door frame, we can put it right.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Big or small, it’s backed by our one-year guarantee.

Looking after it afterwards
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. Outdoor work around Earlston depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Tell us about any water getting in
- Mention any parking rules near the property

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, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Your questions about sand mastic in Earlston
Is Earlston in your area for sand mastic?
Yes, Earlston is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
I let a flat near Tweedbank station. Can you help?

Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Earlston homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Homes close to Earlston Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Tweedbank station, any sash windows need sound mastic to keep draughts and rain out. Managing a site like Earlston High School? Then the mastic around its windows and doors needs looking after like any other building’s.
