Reviews
Trusted by Builders & Developers Across Sydney
Based on 28 reviews
Alliance Civil Group demolished our old warehouse and had the site cleared in under a week. Every disposal receipt was handed over without us even asking. Made our council sign-off completely stress-free.
David Nguyen
Site Manager
We had a fire-damaged property that needed asbestos removal before we could even start rebuilding. Most contractors wouldn’t touch it. Alliance was licensed, sorted the paperwork, and had it handled within days.
Sarah Mitchell
Homeowner
Been using Alliance for excavation work across three of our developments now. Their machinery handles the bigger jobs easily, and they’ve never missed a deadline. Easily the most reliable crew we’ve worked with in Western Sydney.
