Professional Grounds, Inc. Reviews

“This is one of the very best contracting experiences my husband and I have had. Our Project Manager and Landscape Designer showed a true passion for their work.”

Ann T.

“Marta, the landscape architect assigned to our project by Professional Grounds, was an absolute delight to work with. She modified the initial design to work within our budget yet retain the effect we wanted in the backyard. The installation team was efficient, polite, and left everything in tip top shape when they were done. We love the results and would definitely use Professional Grounds again for future landscape work.”

Jane M.

“Professional Grounds exceeded all our expectations in every way. They are, as in their name, professional, from the project manager, to the crew who did the work and everyone else involved in the project. In this rather involved project we believe we have received good value for our investment, as exemplified by the fact we really enjoy looking at the front of our home, both during the day and at night with the new night lighting.”

James Z.

“I had one meeting with my landscape designer who immediately understood the look I was going for when replacing a very old and broken slate walkway from our back gate down to our pool area with a new one. She suggested a border that very nicely complimented our natural back yard setting. They did an outstanding job and were excellent with clean up. I would definitely use them again.”
