Sand mastic in Appin, 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 swap the silicone for it. Typical jobs include weathered mastic on the most exposed windows and mastic round period door frames that has failed, across tenement windows, brick reveals and period & listed homes.
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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Stone surrounds
The stone is treated with care when the old mastic comes out.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.

What affects the quote in Appin
Every job gets its own quote. These are the things that affect it:
- Any mould that needs treating
- Whether the work is at height
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

FAQs for Appin
Does the coastal weather in Appin affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Is Appin within the area you cover?
Yes. Appin 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.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We’ll explain what to expect before we leave.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
What sealant work can’t fix
It helps to know what we can’t do:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Masonry that needs repairing
- Sashes that need overhauling
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.

Sand mastic in Appin: local notes
Appin is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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 Appin, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. If you live in an older home near Appin Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Appin is in Argyll and Bute. Anywhere in PA38, our applicators can take on sand mastic. Appin is one of 118 towns and villages in Argyll and Bute we cover for sand mastic. There’s also a page for Glasgow, roughly 64 miles from Appin.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The process
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job usually takes a few hours per window, depending on the condition of the joints. Outdoor work around Appin depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Appin, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
