What does perc test and soil evaluation cost?
A percolation test typically costs $250 to $1,000, and a full soil profile evaluation for a new system runs $500 to $1,500. The number of test pits and travel to the site drive most of the difference. On raw land this is the test that decides whether the lot is buildable, so it comes before anything else.
What is a perc test and when do I need one?
A percolation test measures how quickly water drains through your soil, which determines whether a site can support a septic system and what type it has to be. You need one before building on an unsewered lot, before a new or replacement system is designed, and often before a lender will close on vacant land.
