About Us

Stewart Allardice was founded in 2012 when Justin Stewart and Paul Allardice merged their extensive experience in the building industry and created Stewart Allardice Construction (Pty) Ltd.

In 2002 Justin Stewart took over the reins from his father Ian Stewart, who had traded in South Africa for over 40 years, bringing with him a fresh approach and modern business acumen.

Paul Allardice contracted locally through Allardice Construction Services over the past 20 years.

After working on a contract together, it made sense to combine their respective skills. They have built up a reputation as a hard working, honest, quality, hands-on contractors. The majority of their work is obtained via referrals from happy customers, builders, engineers and architects alike.

Together, the old school work ethic of integrity, reliability and superior service, as well as quality workmanship, remain one of their fundamental pillars.
