We work in Napa, Sonoma, Marin, Solano, & Contra Costa County

This is a very hard question to answer, but our projects typically range in the $20,000 to $1,000,000 range. We are fully transparent about our pricing, so if you are curious about pricing and would like to know more, just give us a call.

Our estimators are trained to help guide you through the process. We also work directly with several landscape designers, architects and engineers for projects that involve more attention to detail.

Yes! Our license number is 1078372. Feel free to visit www.cslb.ca.gov and search for our business using our license number.

We perform almost all of our projects in-house. There are a few exceptions to that, such as gas lines, high-voltage electrical work and a few others things but, generally speaking, you will have Keystone employees on your project from start to finish.

We have several crews. When our crews start a project, it is the only project they are working on. They do not have other clients or places to be. They will be on your project, and your project only, every day until completion. Each crew has a dedicated foreman who is in charge of the project and will be able to meet with you as often as you would like to answer questions, talk about changes, etc.

This is a hard question to answer and can change throughout the year, but generally speaking you can expect your project to start within 6-8 weeks of signing a contract, but this is dependent on many factors like weather, material availability, etc.

We work on both residential and commercial properties, including office parks, wineries, businesses, vineyards, public use locations, and more.

We specialize in a variety of landscaping styles, from contemporary and modern designs to traditional and Mediterranean-inspired landscapes. Our team works closely with clients to understand their preferences and create a design that aligns with their vision.

We do not offer landscape maintenance services, but if you need a lawn maintenance contractor, let us know and we will connect you with one.

The safety and security of your property are paramount to us. We take all necessary precautions, use state-of-the-art equipment, and follow industry best practices to ensure minimal disruption and maximum safety during the project.
