HomeAdvisor lists us as an Approved Pro with a 4.7‑star rating from 72 reviews, and highlights that we offer emergency services, free estimates and warranties. Whether it’s sprinkler repair, low‑voltage lighting, drainage solutions or complete landscape installation, we design and build tailored outdoor spaces for both residential and commercial properties


From concept to completion, our services cover landscape design, low‑voltage lighting, sprinkler installation and repair, drainage, synthetic and natural turf, tree planting, and hardscape construction.
We emphasize eco‑friendly practices, using water‑efficient irrigation, native and drought‑tolerant plants, and energy‑efficient LED lighting.
This approach not only conserves resources but also creates landscapes that are easy to maintain and resilient during Southern California’s dry seasons.
We pride ourselves on exceptional customer service. Our multilingual staff listens carefully to your goals and provides clear explanations during every phase of the project.
After the installation is complete, we walk you through operation of your irrigation and lighting systems and remain available for seasonal adjustments. Our high ratings on platforms like Yelp and MapQuest reflect the trust we’ve earned in the community.



Every great landscape begins with a thoughtful design. Our designers collaborate with you to develop plans that suit your property’s architecture and your lifestyle. We prepare scaled drawings and 3D renderings and help you select plant palettes and materials. Installation services include:
From Mediterranean and cottage gardens to modern xeriscapes using low‑water plants.
Selection and placement of trees, shrubs and seasonal flowers suited to Southern California’s climate.
Lush, water‑saving synthetic lawns or drought‑tolerant grass varieties.
Patios, pergolas, outdoor kitchens and fire pits for dining and entertaining.
Transform your yard with functional hardscapes. Our team builds patios, walkways, retaining walls, seat walls, and fire features using materials like natural stone, pavers and concrete. These elements add value and create spaces for relaxation and entertainment.







We design low‑voltage lighting systems that highlight architectural features, create ambience and improve security. Services include new installations, upgrades, and outdoor lighting repair. Our preferred fixtures from FX Luminaire and Light Crafters ensure reliability and energy efficiency.
Irrigation keeps your landscape healthy. We handle sprinkler system design, installation, and repair. Our technicians quickly fix leaks, adjust coverage and program smart controllers that adapt to weather conditions. We also install drip irrigation and micro‑spray systems for beds and slopes.

Proper grading and drainage protect your property from water damage. We design and install drainage systems that direct runoff to safe areas and incorporate rain gardens or water harvesting units certified by Aquascape. Water features such as ponds, fountains and waterfalls provide soothing ambience and attract wildlife.
