Free Septic System Installer
Service Agreement
One hit utility line or an unexpected ledge can turn a profitable dig into a six-figure lawsuit that bankrupts your crew. If you're working on a handshake, you're just one bad soil test away from eating the cost of a failed system and losing your equipment to a lien.
Pro Contractor Tip
Insert a 'Hidden Conditions Clause' so the homeowner—not your bank account—pays the bill when you strike solid rock or high groundwater that wasn't on the plans.
Why use a written agreement?
Handshake deals are risky. As a Septic System Installer, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions
What happens if the customer starts adding 'extra' drainage work while I've got the backhoe on site?
You stop the engine and don't restart it until a Change Order is signed. Use your written agreement to define exactly what 'in-scope' means so they know any extra digging costs extra cash upfront.
How do I avoid getting stiffed on the final payment after I've already buried the pipes?
Break the project into milestones where the bulk of the money is in your pocket before the final backfill. A contract with a clear payment schedule ensures you aren't chasing a check once the evidence of your hard work is covered in dirt.
The site plan was wrong and now I'm hitting utilities that weren't marked. Who pays for the delay?
If your contract states the owner is responsible for identifying private lines, you bill for the downtime. Having this boundary in writing prevents you from burning diesel and wages while waiting for a utility crew to show up and fix someone else's mistake.
