Sand mastic in Troqueer
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 explain which is best for yours. If you have gaps between timber frames and stone or brick and mastic round period door frames that has failed, we can put it right.
Mastic can only go onto a dry joint, so outside work in Troqueer depends on the weather. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Where is Mr Mastic based?
We work from Crawley. Our applicators cover Troqueer, along with the rest of our area.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in.
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.
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. Somewhere like Troqueer may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
Getting a quote

Windows and doors in Troqueer
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional 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.
In the older streets around Troqueer Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Dumfries station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Aftercare tips
To keep the joints looking good and working properly:
- Inspect the joints round the windows every year or so
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
- Have rotten timber repaired before new mastic goes in
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
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 we are called out for in Troqueer
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
Keep an eye out for any of the following:
- Silicone on a period window that looks wrong
- Cracked mastic round a front door frame
- Failed mastic on an exposed elevation
- Open joints round the window box
Schools such as Dumfries Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
