"Went above and beyond"

Ethan did an amazing job on installing sod to my much needed front yard landscaping.  The yard was neglected for years with weeds and unwanted growth.  Ethan worked hard non stop and meticulously tilling the dirt and prepping it for sod installation to ensure the grass will sustain and grow healthily.  
Ethan went and beyond in updating me his progress, what he's doing, the purpose of the steps and what he'll do next.
The front yard turned out beautifully.  They were laid correctly and evenly.  I'm reviewing Ethan's work after 6 months since the sod installation and the grass is still thriving.  Additionally, Ethan gave great advice for the sprinkling system and how to care for the grass post installation.  Hardworking, knowledgable and professional.   Highly recommend Ethan for sod installation.

Collier Landscaping is the BEST in San Diego County! We redid our entire backyard and Ethan and his team did a wonderful job. They covered everything from the design, irrigation, new sod install, and decomposed granite too! He was prompt, professional, and kept us updated on the progress constantly. Work with Collier if you want a great deal and great service.

"2 thumbs up!"

I had an existing drip line irrigation system in place, but it hadn't been used for over 6 years. I knew there were several leaks and breaks in the lines.  Plus, since most of the drip line was on a canyon, the lines had shifted around a lot.  We hired Ethan to get everything up and running correctly and optimizing the line placements.  

Ethan completed the project in less than a full day.  All leaks addressed, multiple junction connections replaced, lines laid out properly and staked.  We are completely satisfied.  This turned out better than I expected.  

Ethan is polite, very positive, he communicates clearly and is both confident and highly proficient in his skills.  He's just a darn nice young man, and he knows what he's doing.  I give him 5 stars and 2 thumbs up!  We plan on using him for future landscaping projects.
