Professional soil testing costs $652 to $2,112 for most homeowners, with Angi publishing a $1,382 national average.1 HomeAdvisor publishes the same average and normal range.2 Fixr separately publishes a $1,200 national average for testing pH levels plus pesticide residue, heavy metals, and industrial chemicals, within a $700 to $1,800 average range.3 Prices below are national averages*.
*National averages, not local quotes. Angi figures are from a 2026 guide updated October 2026, HomeAdvisor figures are from a 2025-data guide updated June 2026, and Fixr figures are from a guide updated January 2025. Your price depends on the type of test, lab fees, and whether on-site technicians are needed.

The HomeAdvisor technician and Fixr landscaper hourly figures are identical but labeled for different professionals – distinctly labeled items, not necessarily the same priced service. Fixr notes university lab results typically take about 2 weeks, private labs 2 to 5 business days, and standard reports 5 to 10 business days.
National lab pricing (reported by Fixr, 2025)

| Logan Labs | $20 – $30 | $50 – $60 |
| Midwest Labs | $25 – $35 | $35 – $45 |
These are Fixr’s reported figures for the named labs, not verified current quotes from the labs themselves or confirmation of their current pricing.
