Georgia Structural Repairs not done right!

[Justine Veal]

Hi all, 

My Fiancé and I just closed on first property (8/12). It's a single family. Per our contract the seller was supposed to fix plumbing, electrical and structural issues that we found in the inspection. There was even a detailed letter of what to do drawn up by a engineer. Now that we are settling into the property we are finding that I lot of the work was not done to code. In addition to even more structural damage that was not disclosed to us. I had a building inspector come in and it looks like a lot of the damages and issues that were just covered up. My question to you all is one: Can anyone refer me a lawyer who specializes in real estate in GA. I'm in at Atlanta. Also I'm not sure if any one can answer this question without being a lawyer but is it too late for me to take legal action against the seller?

Thanks in advance
