Kosta & Sons Excavation

The finished result exceeded our expectations. Our project was challenging, with a steep driveway and a curved retaining wall, but the team did an excellent job. The quality of the work was of a very high standard, and communication was great throughout the project. As someone with no construction background, I appreciated how clearly everything was explained. The team was professional, well organised and a pleasure to deal with from start to finish. They kept the site tidy, cleaned up after themselves each day, delivered exactly what was promised, completed the project on time, and offered excellent value for money. I’d definitely use them again for any future retaining wall or concreting work.

Subbied drainage an retaining work out to kosta recently. Completed the work on time, neat an tidy.

I had rick and pat construct a retaining wall for me. His communication was great and the wall came out perfect, i done alot of researching and within minutes I knew rick was the man for the job, thanks again guys.

Exellent piece of work at my site. It was a tuff job but they done very professionally. Well done Rick and team👍👍👍

We are absolutely thrilled with the work Kosta and Sons did on our property. They completely transformed our driveway and front garden—it looks 110% better! Their team is professional, reliable, and truly experts in excavation and exposed aggregate. They didn't just do the work; they provided brilliant solutions to our site’s specific drainage issues. The finished product is high quality, and their attention to detail during the excavation and pouring process was superb. If you need a reliable contractor for concrete and excavation , look no further!"

I engaged Ricky to build my retaining wall and site cut my property in Greenvale, absolute legend to deal with, easy going, job came up perfect, would 100% use again. Thanks again Rick and team.

I called Rick to my Greenvale property, he introduced himself very professional, with a big smile and bubbly personality. His passion for his work just radiated. Easy to talk to and listened as I explained the drainage/concrete issues I was having and a design project I wanted done. He was back with Pat/team they went above and beyond to fix the issues, and saw my vision of the design to my garden with attention to detail and lot's of patients with me 🙃 always with a smile they delivered 110% I'm very happy with Rick and his team worth every cent. I totally recommend them. Great job!!☺️
