Angi list is a scam
"William contacted me within 30 minutes of requesting service through Angi. He was at my house within the next hour, discovered the cause of my busted water line, and completed the job quickly. After 2 days without water and trying several plumbers for help without success, I remembered my Angi account. This was the 1st time I'd used Angi and am so glad I did. I will be calling on this company again in the future for other repairs. Highly recommended."

The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:

Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
