    I have used sonoma landworks on multiple projects for septic installs and repairs, grading and excavation. It is always a pleasure to work with pat who is very professional, honest and cares about his work. As a custom, home builder in sonoma county, i appreciate the quality of work, this company produces.

    Can't say enough about Pat and Sonoma Landworks. I called them for septic work and needed my distribution pipes and boxes replaced. Pat came to look at the job and provided me with a price, which was very reasonable in a timely manner. He gave me a date by which the work could be done. A few days before, he called to let me know he would be there. He completed the work and left the sight better than he found it. Overall, I was very impressed with the company's professionalism and communication. Not the norm in the construction world.

    Taking time to leave a review because I am so pleased with my experience from beginning to end. Disclaimer: I am new gardener. I visited the store and spoke with two young employees that were friendly, knowledgable, and really helpful. I coordinated delivery for dirt a few days later and the delivery guy was prompt, friendly, and efficient. For something that could have been an intimidating experience, it actually was enjoyable and confidence building. I will continue to give my business where I can, and will absolutely refer others here for services. Thanks, team!
