- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.

Advice
Sand mastic for homes and businesses in Insch
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. We work on stone surrounds, period & listed homes and timber door frames, and the jobs we see most are draughty sash windows at the surround and gaps between timber frames and stone or brick.
Mastic can only go onto a dry joint, so outside work in Insch depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Insch homes and the weather
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. 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.
Rented homes near Insch station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

What else we do in Insch
Why act early in Insch
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. 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.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Your questions about sand mastic in Insch
Do you work for landlords with property near Insch station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Insch?
Yes. Insch is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply drop us a line at info@mrmastic.co.uk.
Can you replace silicone on a period window with sand mastic?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
How much does sand mastic cost in Insch?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk with a short description of the job.
How long does sand mastic take?
It depends on the size of the job, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We’ll tell you when we quote.
Looking after it afterwards
After the cure time, these simple habits help:
- Do not paint over the new mastic
- Do not run silicone over sand mastic
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
Should I try it myself first?
If you do try it yourself, take your time over the 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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Different surfaces, different methods
