    “Very professional. Needed to do grading and excavation, they gave me a good price and did a very good job. They also took down a garage for me, and it was very quick and well done. Everything passed inspection on the first try and they were very knowledgeable about the process. I am definitely going to use them again in the future.”

    “Amazing work from these guys! They showed up to my house on time, if not a bit early, and levelled a bit of land for me, and excavated a pool. Additionally, they helped me repair a fence at no extra cost. Amazing work from them, and I recommend them to everyone.”

    “Quality work by really nice guys. I don't normally write reviews, but JHA really worked hard for me. We needed some old tree stumps removed and trenches dug for a project and Jonah and his crew were great. They did exactly what we needed. They even told me how I could save some money and time by changing around a few things, but left the decision up to me so I never felt pushed either way. So glad I hired them and not the gardeners I looked at!”

    “I recently used JHA to redo my landscape. We had to remove a lot of dirt which was previously creating a large hill, and pushed it back so that there was only a small hill towards the back. JHA was extremely professional and quick, and they were very good on the machines. Within 2 days we had the entire hill moved back, 3 trees and the stumps removed, and the third day they removed all of the existing back driveway so that we could turn it into a side yard. They also took down an entire shed that we had in one day, and cleaned up the area very well. They also did an excellent job preparing for the artificial grass that we wanted, and the drainage is very good. Great experience and I would definitely use them again.”
