Sand mastic in Ardminish, done properly
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you’re dealing with crumbling sand mastic round a window and failed mastic on an exposed elevation, we can help, whatever the surface.
In and around a place like Ardminish, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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 fails, we can still redo it.
How it works
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a single window, longer for several, depending on the amount of work. Somewhere like Ardminish may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

What sand mastic looks like in Ardminish
Ardminish is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Homes close to Gigha Parish Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Signs you need sand mastic in Ardminish
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Keep an eye out for these signs:
- Open joints round the window box
- Gaps round a timber door in stone or brick
- A silicone bead on a sash window that spoils the look
- Weathered mastic on the most exposed windows
Around Ardminish, as everywhere, sand mastic is only as good as the preparation behind it.
What your quote should include
- How long the guarantee is
- When the joint can take water or movement
- Which sealant they’ll use, and why
- Who turns up on the day
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In an older home around Ardminish, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Is Ardminish within the area you cover?
Yes, Ardminish is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
How we quote for sand mastic
The price is agreed before any work begins. It takes into account:
- How many areas need sealing
- Working hours on commercial sites
- How easy the joints are to reach
- Whether there’s mould to deal with

Helping us quote
You do not need to know the technical terms. Just tell us:
- The problem you’ve noticed
- The rough size of the job
- Where the property is
- A few pictures by email, if you can
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, send an email to info@mrmastic.co.uk.
Keeping the joints in good condition
So the new joints stay in good condition:
- Clear gutters so water doesn’t pour onto the windows
- Avoid patching sand mastic with silicone
- Sort the mastic before the decorators arrive
- Avoid heavy scraping on the mastic joint
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
