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.

Marisol A.

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.

Dave R.

Villa Park

We have them on contract for two retail centers. Visits are consistent, reports come in, and the properties look sharp all year.

Common questions

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.

Yes. Sierra Landscape LSL carries liability coverage and workers’ compensation, and we’ll send certificates before work starts.

Most residential properties are weekly or bi-weekly. Commercial and HOA sites run on a written schedule with documented visits.

That’s most of our larger work: demo, grading, irrigation, lighting, hardscape and planting handled by one crew and one point of contact.

Maintenance can usually begin the next service week. Installations depend on material lead time, and we give you a date in writing.

Yes. We serve Los Angeles County and the Inland Empire as well check the service areas page or just call and ask.

Free estimate, no pressure, usually within 48 hours.
