What to ask before you hire

• Your county license number, so I can check it before I sign?
• A certificate of insurance sent to me by your insurer, not a photo?
• Will you camera the line and give me the video?
• Is the problem on my side of the property line or the sewer district's?
• Does the repair need a plumbing or road opening permit, and who files it?
• Is it a repair, a lining or a replacement, and why?
