How much does retaining wall cost?
$15–$35 / sq ft for block wall — the range we verified in November 2026. $25–$60 / sq ft for poured concrete.
What does the cheapest option include?
Usually less prep, a thinner material and no permit. Compare the five quote lines rather than the total.
Do I need an inspection first?
For anything structural or above about $5,000, yes. An independent report is cheaper than a wrong scope.
How long does the work last?
Exposure decides more than brand. The methods hub explains the failure mode of each option.
