Artistic Landscapes
Artistic Landscapes
No yearly contracts required for maintenance customers, month to month billing available. OLCB License #9292. Owner and Landscape Contractor: Robert Kinsey. Designer and Office Manager: Sarah Kinsey. Additional email - [email protected]. Award Winning .
"Robert and the team at Artistic Landscapes were so amazing to work with. After my spouse and I fell ill over the summer, we had to let the yard go, and it took us a long time to recover so we never had enough energy to catch up. By the time we called Robert, we felt embarrassed of our yard and anxious to get it resolved. We have struggled in the past getting landscapers to follow through with giving us bids so we were nervous about starting that process again. Other crews that we hired wouldn't complete the job as described and made us feel like we were being difficult for asking questions or speaking up. This was NOT the case with Robert and his team. They were kind, communicative, affordable, flexible and the end product was gorgeous. They promised 100% and gave us 200%. We kept the crew on for monthly maintenance which will ensure that we have a gorgeous yard for years to come. Thanks to Robert, Salvador, Eduardo, Sarah and all of the folks who worked on our project in some way. We are eternally grateful, and feel like proud homeowners again."
