No. NailIt calculates materials only. You're doing the work yourself, so our estimates cover only the supplies and products you purchase—not any contractor or professional installation fees.
Island size, countertop material (laminate vs. quartz), and whether you add a sink or electrical outlets. Larger islands and premium finishes push costs toward the high end.
If your island includes a sink or outlets, most building codes require a licensed electrician or plumber for final connections. Budget materials for rough-in work you can do, and plan for a licensed pro to make final hookups—those service calls aren't included in NailIt's materials estimate.
