Sand mastic for sash & case windows in Inverarity, Angus
We cover Inverarity for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
- Cement or filler used on old window joints that has cracked
Sand mastic in Inverarity, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you’re dealing with old cement repairs round a window that have failed and mastic that needs renewing before redecorating, we can put it right, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
There’s a 12-month guarantee on every job, whatever its size.

Common questions in Inverarity
Is there a guarantee on sand mastic in Inverarity?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to Inverarity?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
When to call us in Inverarity
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint and we normally remove them.
It’s worth asking for a quote if you see:
- Silicone on a period window that looks wrong
- Draughty sash windows at the surround
- Window mastic to renew ahead of painting
- Mastic dropping out of the joint
If you live in an older home near Inverarity Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What sand mastic looks like in Inverarity
With historic houses such as Glamis Castle (about 4.6 miles north-west) nearby, there’s older building stock in the area around Inverarity as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In and around Inverarity, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Renew mastic before redecorating the windows
- Get any rot dealt with first
- Clear gutters so water does not pour onto the windows
- Look over the window mastic once a year
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
