How we handle sand mastic in Kemnay
We work across Kemnay renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you are dealing with silicone on a period window that looks wrong and draughty sash windows at the surround, we can put it right, whatever the surface.
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.
There’s a 12-month guarantee on every job, whatever its size.

Questions from Kemnay
Can you help a landlord with a rental near Kintore station?
Yes. We work for landlords and agents as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Is Kemnay within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you have insurance?
Yes, we are fully insured for every job we do.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
How long does sand mastic take?
It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We will tell you when we quote.

Surface by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we’ll confirm what’s needed.
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
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.

Looking after it afterwards
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
- Make sure water runs off the sill
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Honest limits
A few problems are outside what sealant work can do:
- Decayed frames that need repair
- Cracked or broken glass
- Sashes that rattle, stick or will not open
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Windows and doors in Kemnay
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. 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.
Homes close to Kemnay Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Kintore station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

When to call us in Kemnay
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint and we normally remove them.
Look out for these signs:
- Open joints round the window box
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
- Mastic worn away on windows facing the weather
Schools such as Kemnay Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
