Should landscapers be certified or licensed?

<div>When it comes to landscapers, licensing laws vary. Landscaping architects are required to be licensed in all 50 states, whereas traditional landscaping contractors are not typically required to hold a certification. You’ll likely be working with a landscaping contractor for most residential projects. If you are redesigning your whole yard or adding in hardscape features, you will work with a landscaping architect at some point during the project. Be sure to <a href="https://www.angi.com/angi-license-check.htm">check our state licensing tool</a> to review the local landscaper guidelines.As you browse our pro listings, take note of the “Angi Approved” badge.

This is probably the best thing we've ever had done in our small complex. The company rep was very helpful in explaining the benefits of french drains vs. other types of drainage systems, and we can't be happier! Very prompt, work was done quickly and everyone was easy to deal with.
