Sand Mastic in Dunvegan
Our applicators work in Dunvegan on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

- Gaps between timber frames and stone or brick
How we handle sand mastic in Dunvegan
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. If you’re dealing with silicone on a period window that looks wrong and old cement repairs round a window that have failed, we can put it right, on stone surrounds, period & listed homes and tenement windows alike.
Outdoor sealant needs a dry surface, so window work around Dunvegan is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep modern sealant off the mastic
- Avoid heavy scraping on the mastic joint
- Ask a joiner to look at soft timber first
- Leave the new mastic unpainted
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

What the job involves on each surface

Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.

Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Around Dunvegan, 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.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Questions from Dunvegan
Is sand mastic in a coastal place like Dunvegan any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is Dunvegan within the area you cover?
Yes. Dunvegan is within the area we cover, which takes in towns, villages and rural addresses. We work across all 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?
Normally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
How long does sand mastic take?
Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we’ll tell you how long to expect.
How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It usually takes a few hours per window, depending on the condition of the joints.

Advice
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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 doesn’t work out, we can still put it right.
Windows and doors in Dunvegan
Dunvegan is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Dunvegan, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
