How we handle sand mastic in Drinisiadar
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on timber door frames, sash and case windows and tenement windows, and common reasons people get in touch are mastic worn away on windows facing the weather and silicone on a period window that looks wrong.
Mastic can only go onto a dry joint, so outside work in Drinisiadar depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
You get a 12-month guarantee, the same in Drinisiadar as everywhere else we work.

Drinisiadar questions
Will you come out to Drinisiadar?
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 Drinisiadar any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is the work guaranteed?
You get our one-year guarantee on every job.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.
Can you replace silicone on a period window with sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

What else we do in Drinisiadar
Drinisiadar homes and the weather
Drinisiadar 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’s hard on the mastic around older windows and doors, especially on the side facing the sea. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
Around Drinisiadar, as everywhere, sand mastic is only as good as the preparation behind it.
Drinisiadar (Gaelic: Drinishader) is in Na h-Eileanan Siar. Drinisiadar gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Drinisiadar is one of 87 places in Na h-Eileanan Siar we cover for sand mastic.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How the job changes by surface
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
How to look after the new joints
After the cure time, these simple habits help:
- Look over the window mastic once a year
- Ask us before painting near the mastic
- Take care around the mastic when scraping paint
- Clear gutters so water doesn’t pour onto the windows
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Honest limits
It helps to know what we cannot do too:
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
- Sash cords, weights and draught-proofing of the sashes
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before you book.

For landlords and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When to call us in Drinisiadar
Water gets into small cracks in the mastic and loosens it further. Exposed elevations usually fail first.
Signs it’s time to call us include:
- Draughts and rain around sash boxes
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
- Weathered mastic on the most exposed windows
Whether the job is in Drinisiadar itself or nearby, the right material for each joint matters as much as a neat finish.
