Aluminium windows and doors you can stop worrying about.
Since 2008, homeowners, builders, architects and businesses across the Western Cape have trusted us to measure, supply and install the windows and doors their buildings depend on.
From frames you fight with, to ones you forget about.
The problems people bring to us are surprisingly similar. So is what happens after we have been.
What people tell us
- Doors that stick, rattle or let the wind in
- Standard sizes forced into openings that don’t match
- Quotes that don’t say what you are paying for
- Installers who are hard to reach once they have left
With Greenline
- Frames that slide, close and lock smoothly
- Every item made to the exact size of your opening
- A written quote listing products, finishes and glass
- One team that measures, installs and comes back
Proudly Western Cape since 2008.
We supply and install standard aluminium products for homes, large companies and industrial sites across the Western Cape, and take on custom products for special jobs. Everything is built to measure by professional aluminium suppliers we trust, and installed by our own team.
We work for homeowners as well as for more than 30 architects and builders. Our experience lets us take on work of any size, from a single shower to a wedding venue, with the same care.
To bring style, security and sophistication to every building we work on, with aluminium that fits first time and a team that is still there years later.
