About our sand mastic in Achiltibuie
We work across Achiltibuie renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on timber door frames, period & listed homes and tenement windows, and common reasons people get in touch are cracked mastic round a front door frame and gaps where the frame meets the masonry.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
There’s a 12-month guarantee on every job, large or small.

Why deal with it now?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around Achiltibuie, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

Questions from Achiltibuie
Does living near the coast affect sand mastic in Achiltibuie?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover Achiltibuie for sand mastic?
Yes. Our work covers the whole of Scotland, and Achiltibuie is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
What sand mastic looks like in Achiltibuie
Achiltibuie 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Achiltibuie, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. For jobs in and around Achiltibuie, choosing the right material for each joint is as important as a tidy finish.
Achiltibuie is in Highland. Anywhere in IV26, we can carry out sand mastic at your property. Achiltibuie is one of 253 towns and villages in Highland where we work.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep modern sealant off the mastic
- Plan mastic work ahead of painting
- Look over the window mastic once a year
- Go gently near the mastic when preparing windows
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
What the job involves on each surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Putty and glazing repairs
- Timber that has rotted
- Whether work needs listed building consent
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before booking.
Joints and surfaces we work on
- Stone surrounds
- Tenement windows
- Brick reveals
- Sash and case windows
- Period & listed homes
- Timber door frames
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes anything from a few hours to a full day, depending on how many windows, depending on how much there is to do. Outside jobs in Achiltibuie 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. Work indoors isn’t affected.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work

Related advice
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
