We had a wonderful experience with Koch & Associates. We hired them to completely redo our backyard and now we have a beautiful Trex deck, a lovely fire pit with seating and a swimming pool with a substantial swim deck. We couldn’t be happier with the result. I wholeheartedly recommend them to anyone looking for top-quality, conscientious landscape design and construction.

I have used Koch and Associates for big jobs and smaller jobs with the firm handling all aspects of the work, from design, permits and installation. Very high-quality professional workmanship. I highly recommend them to all my friends for landscaping needs.

We are super pleased with the work, communications, design and professionalism of everyone at Koch & Associates. We did a complete redesign and remodel of our front and back yard. All of the stone work is fabulous. They put in a new irrigation and lighting systems. Plants and trees fit our yard perfectly. if you are looking to get your yard done, give them a call!

Koch & Associates did a great job for us. They were very helpful during the design process and created the attractive and low maintenance yard that we wanted. They started on the day that they said they would start, and finished on the day they said they would finish. I would highly recommend their work to anyone.

We cannot begin to tell you how great of a job these guys did. Very professional, did exactly what they said they would do, and they are very detailed oriented. 40 plus years of experience really showed while engaged with this company. A class act organization that I would not hesitate to recommend to anyone. Do yourself a favor and choose this contractor.

I renovated my entire yard, softscape and hardscape, with Koch & Associates Landscape Company.  Their landscape designer is extremely knowledgeable and designed the perfect yard for me.  The demo work was quick and clean.  The new irrigation and lighting systems are energy efficient. The plantings are drought tolerant and low maintenance.  The yard is absolutely beautiful!

Tina C

We used Koch & Associates to redo our back and front yards. They did a great job listening to and understanding our needs.  They came up with the design and execution plan and estimate within our budget. The one thing I liked about them is that once the work started, they didn’t get sidetracked to do other jobs. They even worked on a Saturday and finished the project slightly ahead of time!
