Sand mastic for homes and businesses in An Tairbeart
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on tenement windows, sash and case windows and timber door frames, and common reasons people get in touch are old cement repairs round a window that have failed and gaps where the frame meets the masonry.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Every job comes with our 12-month guarantee, wherever you are in Argyll and Bute.

Sand mastic in An Tairbeart: local notes
An Tairbeart is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
In and around An Tairbeart, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

FAQs for An Tairbeart
Is An Tairbeart within the area you cover?
Yes. An Tairbeart is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do sand mastic in An Tairbeart?

What do you need from me for a quote?
Let us know what needs doing and where. If we need more, we will ask.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Can you match the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before we start.
Which is right for my windows, sand mastic or modern sealant?
We will help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk.

Can I do it myself?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How the job changes by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. Outdoor work around An Tairbeart depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
