Dunecht Sand Mastic
We cover Dunecht for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Window mastic to renew ahead of painting
- Open joints round the window box
- Crumbling sand mastic round a window
How we handle sand mastic in Dunecht
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on tenement windows, brick reveals and period & listed homes, and common reasons people get in touch are a silicone bead on a sash window that spoils the look and draughts and rain around sash boxes.
In and around a place like Dunecht, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Every job comes with our 12-month guarantee.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. For a place like Dunecht, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Tell us about any water getting in
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Clear gutters so water doesn’t pour onto the windows
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

What the job involves on each surface
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.

What affects the quote in Dunecht
You’ll get a clear quote before we start. It takes into account:
- Which sealant suits the joint
- Mould in or behind the old joints
- Access and height
- How much there is to do
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
To make quoting easier, let us know:
- Where the property is
- The problem you’ve noticed
- If someone has resealed it before
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved.
Common problems we fix in Dunecht
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
Most people get in touch when they notice something like this:
- Gaps between timber frames and stone or brick
- Tired mastic found when preparing windows for paint
- Draughty sash windows at the surround
- Patchy fillers round a sash window
Around Dunecht, as everywhere, sand mastic is only as good as the preparation behind it.
Questions to ask before you book
- How long to leave it before use
- Whether they’re fully insured
- Whether the sealant suits the joint
- Who turns up on the day
When something else is needed
We will not take on work that will not last, so here’s what sealant can’t put right:
- Planning or listed building consent (your local planning authority decides)
- Sashes that need overhauling
- Crumbling stone or brickwork round the window
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
What we seal

Your questions about sand mastic in Dunecht
Is sand mastic in Dunecht guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Dunecht?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes and newer frames suit modern sealant.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Frames and glazing around Dunecht
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For jobs in and around Dunecht, choosing the right material for each joint is as important as a tidy finish.
