Sand mastic in Auchnagatt, done properly
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you’re dealing with gaps where the frame meets the masonry and crumbling sand mastic round a window, we can put it right.
Mastic can only go onto a dry joint, so outside work in Auchnagatt depends on the weather. Tell us about access to all the windows and doors, upstairs included.
All our work comes with our one-year guarantee, wherever you are in Aberdeenshire.

Common questions in Auchnagatt
Can you do sand mastic in Auchnagatt?
Yes, Auchnagatt is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Is there a guarantee on sand mastic in Auchnagatt?
All our work, in Auchnagatt and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Where are you based?
We work from Crawley. Our applicators cover Auchnagatt.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Auchnagatt.
Looking after it afterwards
To keep the joints looking good and working properly:
- Sort the mastic before the decorators arrive
- Clear gutters so water doesn’t pour onto the windows
- Leave the new mastic unpainted
- Avoid patching sand mastic with silicone
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Landlord and commercial work in Auchnagatt
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Sand mastic in Auchnagatt: local notes
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 Savoch Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Around Auchnagatt, as everywhere, sand mastic is only as good as the preparation behind it.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. 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.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know about parking restrictions
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Leave it or put it right?
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
