About our sand mastic in Fountainhall
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on timber door frames, period & listed homes and sash and case windows, and the jobs we see most are patchy fillers round a sash window and tired mastic found when preparing windows for paint.
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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Questions from Fountainhall
I let a flat near Stow station. Can you help?

Is Fountainhall in your area for sand mastic?
Yes, Fountainhall is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Where do you work from?

What does sand mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk and tell us what needs doing and where.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
How long does sand mastic take to harden?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Looking after it afterwards
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Avoid patching sand mastic with silicone
- Have rotten timber repaired before new mastic goes in
- Check with your local planning authority if your home is listed
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Why deal with it now?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

When to call us in Fountainhall
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber and we normally remove them.
Look out for these signs:
- Modern sealant on a period surround
- Mastic dropping out of the joint
- Gaps between timber frames and stone or brick
- Mastic round period door frames that has failed
If you let a flat or house near Stow station, older sash windows in a rental need their mastic kept sound to keep the weather out.

- Which colour the sealant will be
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
What we do, step by step
Before we leave, we go over the finished joints with you. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the amount of work. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work

Frames and glazing around Fountainhall
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, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In and around Fountainhall, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
