About Us
Landscapers who genuinely care
Since 1987, All Seasons has designed and built outdoor spaces across Orange County — with honesty, craftsmanship, and a love for the work.
Our Story
The mission behind our landscaping services
Established in 1987 and based in the Newport Beach area, All Seasons Sprinkler & Landscaping specializes in sprinkler repair and installation, low-voltage landscape lighting, drainage, synthetic and natural turf, planting, and complete landscape design.
We serve homeowners and businesses throughout Orange County — with our main areas in Newport Beach, Newport Coast, and Corona del Mar — offering complimentary estimates and online references. Fully licensed, bonded, and insured, we back our work with a one-year warranty because we believe a landscape should be built to last.

David Keane, Lead Landscaper
