Sand mastic for homes and businesses in Hill of Keir
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We’re often asked to deal with cracked mastic round a front door frame and a silicone bead on a sash window that spoils the look, on period & listed homes, timber door frames and sash and case windows.
In and around a place like Hill of Keir, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Signs you need sand mastic in Hill of Keir
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
People normally contact us when they notice something like this:
- Weathered mastic on the most exposed windows
- Cement or filler used on old window joints that has cracked
- Mastic dropping out of the joint
- Draughty sash windows at the surround
For an older house near a landmark such as Belhelvie North Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Before you book anyone
- When the joint can take water or movement
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- What product goes in the joint
How it works
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Around Hill of Keir, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- 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
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Hill of Keir questions
Does the coastal weather in Hill of Keir affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you cover Hill of Keir for sand mastic?
Yes. Our work covers the whole of Scotland, and Hill of Keir is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic generally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.
Can you replace silicone on a period window with sand mastic?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
What the job involves on each surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Windows and doors in Hill of Keir
Hill of Keir is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Hill of Keir, as everywhere, sand mastic is only as good as the preparation behind it.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
