Sand mastic in Annathill
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you have mastic dropping out of the joint and mastic worn away on windows facing the weather, we can help, on timber door frames, stone surrounds 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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In a place like Annathill, 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. You’ll know the price before we begin.

What affects the quote in Annathill
Every job gets its own quote. These are the things that affect it:
- Access and height
- Mould in or behind the old joints
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- The rough size of the job
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.
What we do, step by step
The work is kept neat and contained to the area we are working on. The job normally takes a few hours per window, depending on the condition of the joints, and we explain the cure time before we leave. Outside jobs in Annathill need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
Getting a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Related advice
Sand mastic in Annathill: local notes
Annathill is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Greenfaulds High School, its window and door frames need their mastic kept sound, just like a home’s.

What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
- Sashes that need overhauling
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
Joints and surfaces we work on
- Stone surrounds
- Period & listed homes
- Brick reveals
- Tenement windows
- Sash and case windows
- Timber door frames
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Check the mastic when you check the paintwork
- Don’t paint over the new mastic
- Find out about consent before window work on a listed home
- Make sure water runs off the sill
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
