Question Answers

As a Duarte homeowner, how do you address common issues like overwatered lawns and mulch erosion?

We see these issues frequently in our area. For overwatering, our irrigation design services include installing smart, water-efficient systems with proper zoning and timers tailored to Duarte's microclimates. We also perform irrigation audits and repairs to fix leaks and adjust spray patterns. To combat mulch erosion, especially on slopes, we use erosion-control techniques and recommend durable materials or alternative ground covers that stay in place, ensuring your landscape investment is protected and sustainable.

What does your landscape design and construction process involve for a project like a new patio or retaining wall?

Our process starts with a free design consultation to understand your vision and site specifics. With my Cal Poly Pomona background in landscape architecture, I create a detailed plan that integrates hardscaping—like patios, walkways, or retaining walls—with the overall landscape. During construction, I'm on-site daily to supervise, ensuring quality installation with materials that carry strong warranties. We handle everything from permits to final grading, making the process seamless for you.

Do you handle tree removal and hillside work, and are you compliant with local regulations?

Yes, we offer complete tree services, including safe removal and artistic pruning. For hillside clearing and landscaping, we are well-versed in local fire regulations and always meet or exceed the Fire Marshal's requirements. We use specialized techniques and products for hillside retention and drainage to create stable, beautiful, and compliant landscapes. Our 32 years of experience in the San Gabriel Valley means we understand the specific challenges of working on Duarte properties.
