Sand mastic in Achintee, done properly
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on timber door frames, sash and case windows and brick reveals, and common reasons people get in touch are a silicone bead on a sash window that spoils the look and gaps between timber frames and stone or brick.
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.
We stand behind the work with a one-year guarantee.

What else we do in Achintee
What happens if it’s left?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Around Achintee, water from a failed joint in an older stone home can soak into timber and plaster.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- The number of rooms or windows
- Access and height
- When we can work, for business premises
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- Photos by email, if that’s easy
- Where the property is
- If someone has resealed it before
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Achintee: your questions answered
Do you cover smaller places like Achintee?
Yes, Achintee is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Does living near the coast affect sand mastic in Achintee?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Can you replace silicone on a period window with sand mastic?
Normally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available.
How long will you be here?
Most jobs take a few hours for a single window, longer for several. Your quote will say how long we expect yours to take.
How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. Outside jobs in Achintee need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- 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.
How to prepare
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Move anything stored near the joints

Achintee homes and the weather
Achintee is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Strathcarron station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Achintee is in Highland. Homes, rented property, offices and hotels in Achintee is covered for sand mastic. Every job comes with our one-year guarantee. Achintee is one of 253 towns and villages in Highland where we work for sand mastic.

Signs you need sand mastic in Achintee
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
Most people get in touch after spotting something like this:
- Old cement repairs round a window that have failed
- Tired mastic found when preparing windows for paint
- Draughty sash windows at the surround
- Failed mastic on an exposed elevation
If you look after a building such as Kirkton in Meikle Strath School, its window and door frames need their mastic kept sound, just like a home’s.
