Sand mastic in Eòlaigearraidh
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 talk through which suits your home. If you have open joints round the window box and weathered mastic on the most exposed windows, we can help, on tenement windows, brick reveals and sash and case windows alike.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All our work comes with our 12-month guarantee, wherever you are in Na h-Eileanan Siar.

Sand mastic in Eòlaigearraidh: local notes
Eòlaigearraidh 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. Island weather, with its wind and salt spray, is tough on the mastic around older windows and doors.
For jobs in and around Eòlaigearraidh, choosing the right material for each joint is as important as a tidy finish.

Your questions about sand mastic in Eòlaigearraidh
Will you come out to Eòlaigearraidh?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Is sand mastic in a coastal place like Eòlaigearraidh any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
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.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How long will you be here?
As a guide, most jobs take a few hours for a single window, longer for several. Bigger jobs take longer, and we will say how long yours will take.
Are you insured?
Yes. We are fully insured.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Check with your local planning authority if your home is listed
- Get any rot dealt with first
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Housing providers, facilities teams and property managers book us too in Eòlaigearraidh and across Na h-Eileanan Siar. We can quote a run of properties together.
Why act early in Eòlaigearraidh
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

What we’re called out for in Eòlaigearraidh
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Signs it’s time to call us include:
- Old cement repairs round a window that have failed
- Gaps round a timber door in stone or brick
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
Around Eòlaigearraidh, as everywhere, sand mastic is only as good as the preparation behind it.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
