Top 10 Landscaper in Addison, IL

Demand proof of a current Illinois Department of Agriculture pesticide license; general liability insurance alone is legally insufficient for chemical lawn care.

Verify that any hardscape proposal includes a minimum 12-inch crushed aggregate sub-base to withstand the severe DuPage County winter freeze-thaw cycles.

Ensure the contractor provides a written grading plan that explicitly respects the Salt Creek watershed drainage easements and local municipal setbacks.

Ask for a detailed list of native Illinois cultivars they intend to use, which drastically reduces long-term irrigation costs.
