US construction has specific pain points — from lien laws to verbal agreements that don't hold up in court.
Every US state has different mechanic's lien rules. Without written change orders, your lien rights may be weakened or void.
"The homeowner said it was fine" doesn't work in American courts. You need a paper trail — on every extra, every time.
AIA G701 change orders have strict requirements. Verbal approvals on AIA projects can disqualify your entire claim.
The average US renovation project has 4–7 undocumented scope changes. At $1,500 each, that's $6K–$10K walked out the door.

We were eating $3,000–$5,000 on every bathroom remodel. Homeowners would say 'sure, add the heated floors' then argue about the price at invoice time. JobHammers ended that completely.
