Don't Risk Your Home's Equity

⚖️

Supplier Debt Lawsuits

Cheap contractors often rob Peter to pay Paul. When they default on lumber bills for your project, Affton law allows suppliers to sue you directly for the balance.

🛑

Stop Work Orders

City inspectors patrol Affton daily. Unpermitted work gets red-tagged immediately. You will pay **double permit fees** plus administrative fines to resolve it.

🏥

Bankruptcy Risk

A single injury on your property can exceed your homeowner's liability cap. Uninsured 'handymen' expose your personal savings to massive medical claims.
