Hey Y'all, looking for some advice. I had an electrical company come out just to install some receptacles in a few areas of the house. They took a look at my panel and immediately started talking about water damage and damage to the bus bar. Then they quoted me almost $12k to replace it (and upgrade from 150 to 200A). Obviously I'm not going with them because that's a ridiculous price.

I had 2 other electricians come out to take a look. One I only told them I was interested in upgrading the panel to 200A. He looked at it and then left to write up the quote, didn't say anything about water damage. The other electrician knew about the first company. He opened it up, said he saw no signs of water damage or damage to the bus bar. His recommendation was just a rejuvenation of the panel with new breakers (which is something I was aware was needed when I moved in). He also said that in the future, if I wanted to add more circuits, he'd just add a panel next to my existing one and tie it in - which would work the same and be way cheaper.

Ultimately, just looking for advice on what people think based on the photos. Do I need a new panel and is it a good idea to add a secondary panel in the future? 

Thank you in advance!!

Do I need a new panel?
