What we do not do

• Do not publish fake reviews or fabricated contractor profiles.
• Do not claim Oregon CCB licenses or contractor credentials we do not hold (we are a referral directory).
• Do not perform gutter cleaning or roof moss removal — work is by independent CCB-licensed contractors.
• Do not provide contractor-licensing legal interpretation. CCB requirements, insurance minimums, and bonding amounts vary by license class; always verify current rules at oregon.gov/CCB.
