About our sand mastic in Birchburn
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we’ll talk through which suits your home. If you are dealing with open joints round the window box and crumbling sand mastic round a window, we can help.
Outdoor sealant needs a dry surface, so window work around Birchburn is planned around the weather. Let us know about access to every frame, including any upstairs.
There’s a 12-month guarantee on every job.

Birchburn homes and the weather
Birchburn is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For an older house near a landmark such as St Molios Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several. Outside jobs in Birchburn need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Keep children and pets away from the work area
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

When to call us in Birchburn
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
If you can see any of these, it’s time to have the joints looked at:
- Wind and rain getting in round a sash window
- Mastic dropping out of the joint
- Patchy fillers round a sash window
- Modern sealant on a period surround
Around Birchburn, as everywhere, sand mastic is only as good as the preparation behind it.
What your quote should include
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- Whether they seal over old material or remove it
- What product goes in the joint
Aftercare tips
So the new joints stay in good condition:
- Don’t paint over the new mastic
- Clear gutters so water does not pour onto the windows
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

Your questions about sand mastic in Birchburn
Does living near the coast affect sand mastic in Birchburn?
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.
Do you cover smaller places like Birchburn?
Yes. Birchburn is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Different surfaces, different methods
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
