I had a small project of fixing some broken sprinklers, and we were able to tack on some additional work with the landscaping as well as treating some tree disease. We were very happy with each project, and would will call on Rockwatergrass again.

Dave did an outstanding job pruning my trees and went above and beyond by pointing out other areas that needed attention. He provided a clear, line-by-line estimate and worked with me to prioritize the most critical items based on my budget. There was no pressure or hard sell—just genuine advice and a willingness to help. He’s professional, easy to work with, and truly cares about the health of your garden. I'll be hiring him again in the spring!

Thanks so much Susan ! It was a pleasure working for you .
I'll be back for the lawn seeding come Spring and I know we barely discussed it , but I'm still trying to think of a creative way to prop up that Wisteria ''snake'' running through the garden . I'll figure something out by Spring .

Dave was really great ! He came by the first time to review the work. I really appreciated that he told me what would be valuable and what I should hold off on. This is the way to make people like me repeat customers - by focusing on long term trust.
He then came back for the job and did really great work ! He'll be top of my list for future landscaping work at my current home or anywhere I move in the future

Dave gave me a time that he would be coming by to check the sprinkler system and he showed up on time. He immediately went to work and checked all my sprinklers and fixed anything that needed fixed.
Totally great service, and price was good!
He really knows what he’s doing with sprinklers
I have used some text several times now and have had all good people doing the work
Thank you again for being so responsive!

Best.
Great attention to details, listens, executes once overall project is agreed upon from start to finish. Professional designer, very experienced, very knowledgeable in all aspects of landscape design and execution. Takes full ownership for project. Always on-sight, as needed. Amazing follow-up once project is completed. Checks in periodically to be sure completion of project is stable and client is happy. Always available via text, email, & cell and responds quickly before during and after project is completed.
The nature of the job is such that on any day anything can happen and delay or push out an expected visit, delivery, or workday. It’s the nature of the job and all parties involved should be flexible and understanding. But, one thing is constant, Dave will ALWAYS communicate any delays and the reasons why.
Couldn’t be more pleased with how the project was managed. Getting positive feedback from everyone that passes by.
WE ARE very happy with the end result, and the result is even better than we could have imagined. BRAVO!
Highly recommend

T & R , it was a pleasure working with the two of you ! Thanks for letting us re create your front yard ! Eventually , hopefully you'll find that right maintenance crew that serves your area . Sorry we dont service that far south but happy we are still in contact to keep all the plants healthy despite some of the ones that didnt make it . Replacements on the way !

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
We try very hard to work within everyone's budget to bring their projects to fruition . We are competitive , transparent and honest in our pricing , trying to balance both client and employee needs in order to make it all work in a very expensive and challenging Bay Area economic climate .
What is your typical process for working with a new customer?
The initial process always varies , but generally begins with a meeting , a discussion of your wants and desires for the project , an estimate of cost , more meetings , to fine tune what needs to get done and how we're going to accomplish it , designs , more ideas , more discussions and then finalizing numbers , designs and legal guidelines and final contract . That's for the big projects . For the small projects , a quick meeting , some detailed discussions , agreement and work commences . We pride ourselves on not having you wonder what's happening from day to day , we communicate , a lot because not knowing what's happening during the course of your project is not an option for us .
What education and/or training do you have that relates to your work?
Horticulture degree from Cal Poly in San Luis Obispo . Horticulture degree / Foothill college / Large ranch property management in Colorado / Washington / California .45 plus years of horticultural experience and hands on training .
