What our customers say
Pulled from real reviews left by San Diego homeowners.
"Ethan did an amazing job installing sod to my much needed front yard. He worked hard, meticulously tilling and prepping the dirt. Six months later the grass is still thriving. Hardworking, knowledgeable, and professional."
"Collier Landscaping is the BEST in San Diego County! We redid our entire backyard — design, irrigation, new sod, and decomposed granite. Prompt, professional, and kept us updated the whole way."
"We hired Ethan to fix a drip irrigation system that hadn't run in 6 years. He finished in under a day — every leak addressed, junctions replaced, lines re-staked. Better than I expected. 5 stars and 2 thumbs up!"
