About Sierra Landscape LSL
A family-owned landscaping company built on honesty, quality workmanship and treating every property as if it were our own.
From the owner
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.
The name LSL is more than just a logo it represents my family and the people who inspire me every day.
As a family-owned business, we believe in honesty, quality workmanship, and treating every property as if it were our own. Whether it’s landscape maintenance, irrigation, planting, or a complete landscape renovation, we’re committed to delivering dependable service and results our customers can be proud of.
How we work
Walk the Property
We meet you on site, look at the existing landscape, irrigation, drainage, and overall conditions, and listen to what you want to accomplish.
Plan & Estimate
We discuss the best options for your property, determine the scope of work, and provide a clear estimate for the project.
Complete the Work
Our crew arrives prepared and completes the work with attention to quality, safety, and respect for your property.
Final Walkthrough
We review the completed work with you, make sure everything is cleaned up, and confirm you’re satisfied with the finished project.
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.
