Sand mastic in Bowden, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We’re often asked to deal with gaps where the frame meets the masonry and a silicone bead on a sash window that spoils the look, across sash and case windows, stone surrounds and period & listed homes.
Outdoor sealant needs a dry surface, so window work around Bowden is planned around the weather. Let us know about access to every frame, including any upstairs.
Big or small, it’s backed by our 12-month guarantee in Bowden and across the Scottish Borders.

Your questions about sand mastic in Bowden
Do you cover smaller places like Bowden?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Tweedbank station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Is it worth trying it myself?
Sometimes. 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.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you need sand mastic in Bowden?
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
The problems people usually mention when they call are:
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
- Gaps round a timber door in stone or brick
- Old cement repairs round a window that have failed
Rented homes near Tweedbank station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- Who does the work, and how experienced they are
- What guarantee comes with the work
- What product goes in the joint
- What happens if the job turns out different
Windows and doors in Bowden
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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In the older streets around Bowden Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
When something else is needed
A few problems are outside what sealant work can do:
- Crumbling stone or brickwork round the window
- Putty and glazing repairs
- Sashes that need overhauling
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
Surfaces we seal
- Stone surrounds
- Timber door frames
- Brick reveals
- Sash and case windows
- Tenement windows
- Period & listed homes
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around Bowden, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
