Sand mastic in Newmachar
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Typical jobs include cracked mastic round a front door frame and old sand mastic that has cracked, crumbled or fallen out, on tenement windows, timber door frames and brick reveals.
Outdoor sealant needs a dry surface, so window work around Newmachar is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
There’s a 12-month guarantee on every job, whatever its size.

What the job involves on each surface
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we will confirm what’s needed.
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Keeping the joints in good condition
So the new joints stay in good condition:
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
- Keep sills and gutters clear so water drains away
- Check the mastic when you check the paintwork
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
Newmachar: your questions answered
Do you cover smaller places like Newmachar?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Newmachar for sand mastic?
Yes. Our work covers the whole of Scotland, and Newmachar is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.
How long does sand mastic take?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll say how long yours will take.
Is it possible to take out silicone and use sand mastic instead?
Normally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you guarantee sand mastic work?
You get our one-year guarantee to all our work.
How the visit works
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area

Advice
Leave it or put it right?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. Around Newmachar, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

When to call us in Newmachar
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
The problems people generally mention when they call include:
- Crumbling sand mastic round a window
- Cracked mastic round a front door frame
- Weathered mastic on the most exposed windows
- Draughts and rain around sash boxes
If you look after a building such as New Machar Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- What happens if they find a problem under the old sealant
- How long to leave it before use
- What product goes in the joint
- How long the guarantee is
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
- Putty and glazing repairs
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

Newmachar homes and the weather
Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In the older streets around Newmachar Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Dyce station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
