Sand mastic in Dunkeld
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you are dealing with old cement repairs round a window that have failed and modern sealant on a period surround, we can put it right, on sash and case windows, stone surrounds and timber door frames alike.
Outdoor sealant needs a dry surface, so window work around Dunkeld is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
A one-year guarantee comes as standard, so you are covered after we have gone.

How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Outdoor work around Dunkeld depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
What we are called out for in Dunkeld
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
These are the problems we are asked about most:
- Gaps round a timber door in stone or brick
- Open joints round the window box
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
For landlords with property near Dunkeld & Birnam station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Is Dunkeld in your area for sand mastic?
Yes, Dunkeld is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
How long will you be here?
A typical job takes anything from a few hours to a full day, depending on how many windows, including the preparation. We’ll confirm how long when we quote.
What information do you need?
Let us know what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Putty and glazing repairs
- Sash cords, weights and draught-proofing of the sashes
- Decisions on consent for listed homes
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.

Windows and doors in Dunkeld

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.

DIY sealant or a professional job?
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. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
