Sand mastic in Stoneywood
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 and built up by hand. On older homes, it suits the building far better than silicone. We work on period & listed homes, timber door frames and tenement windows, and people most often call us about patchy fillers round a sash window and open joints round the window box.
In and around a place like Stoneywood, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
Your job is guaranteed for a year, as with all our work.

Frames and glazing around Stoneywood
Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you live in an older home near Church Of Scotland, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Bucksburn Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single window, longer for several. Outside jobs in Stoneywood need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Tell us about any water getting in
- Mention any tricky access

Advice
How to look after the new joints
Looking after new joints is easy:
- Have rotten timber repaired before new mastic goes in
- Plan mastic work ahead of painting
- Go gently near the mastic when preparing windows
- Make sure water runs off the sill
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
FAQs for Stoneywood
Can you do sand mastic in Stoneywood?
Yes, Stoneywood is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Can you help a landlord with a rental near Dyce station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
How long does sand mastic take to harden?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Should I use sand mastic or silicone?
We will talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
When to call us in Stoneywood
Water gets into small cracks in the mastic and loosens it further. Exposed elevations generally fail first.
Any of these means the joints need attention:
- Cracked mastic round a front door frame
- Crumbling sand mastic round a window
- Modern sealant on a period surround
- Gaps between timber frames and stone or brick
Letting a property close to Dyce station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before booking
- Who turns up on the day

What else we do in Stoneywood
Why deal with it now?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. In an older home around Stoneywood, damp from a failed joint can get into timber and plaster.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why us?
- An ARBOMaster approved applicator
- We are fully insured
- Anti-fungal sanitary silicone in wet areas
- Experience in homes, commercial sites and hotels
