Hear From Our Happy Customers

“Helene caused a mud slide in my side yard that came dangerously close to the foundation of my house. Greenspan Landscaping has built a very large retaining wall and put in french drains to stabilize the bank and drain water coming off the mountain into the creek.
Adam Greenspan and his crew, Dakota, Noah, Isaac, Josh and Kolten were very professional and did an excellent job. I greatly appreciated Adam and Kevin keeping me informed on every step of the construction with regular texts.”
— Lynn G., Google Review
“Kevin did a great job repairing and replacing the downspout extension. He also took out 3 small trees and removed all debris. He helped with recommendations. His price was fair for all the work that was done in a timely and courteous manner.
