Clean bed edges, weed barrier where it belongs, and mulch or rock that holds moisture and looks finished.
Drag the handle. Same walkway, six days apart.
A bare dirt entry in Villa Park became a flagstone path with turf joints, new low-voltage lighting and replanted color beds. Every project starts with the same free walkthrough.
The name LSL is my family
My name is Lionel Sierra, owner of Sierra Landscape LSL. I started this company with a passion for creating beautiful outdoor spaces and providing reliable, high-quality landscaping services throughout Orange County.
Yards and grounds across the region

What neighbors say after we leave
Lionel found the leak two other companies missed, fixed the valve and reset the whole system in an afternoon. Our water bill dropped the next cycle.
Tustin
They took our front yard from dirt to a finished walkway in under a week. The crew cleaned up every single day before leaving.
Villa Park
We have them on contract for two retail centers. Visits are consistent, reports come in, and the properties look sharp all year.

Answers before you call
Still unsure? Call and ask for Lionel you’ll get a straight answer, not a sales script.
Do you charge for estimates?
No. We walk the property, talk through what you want and send a written estimate at no cost.
Are you licensed and insured?
Yes. Sierra Landscape LSL carries liability coverage and workers’ compensation, and we’ll send certificates before work starts.
How often do maintenance visits happen?
Most residential properties are weekly or bi-weekly. Commercial and HOA sites run on a written schedule with documented visits.
Can you handle a full landscape renovation?
That’s most of our larger work: demo, grading, irrigation, lighting, hardscape and planting handled by one crew and one point of contact.
How soon can you start?
Maintenance can usually begin the next service week. Installations depend on material lead time, and we give you a date in writing.
Do you work outside Orange County?
Yes. We serve Los Angeles County and the Inland Empire as well check the service areas page or just call and ask.
