Back in 2015 my mom had a retaining wall in front of her house replaced and it is beginning to crack. I checked the contract and it states there is a 5 year "workmanship warranty". My mom has been calling the contractor for about 6 months to a year telling him she sees cracks forming but he tells her to look into other issues like street vibration issues that has previously affected the past walls stability. He won't even come look at it I am fed up with how he is handling this and looking into the contract to see what he actually "owes" us and if he is supposed to fix it, I will step in and if he does not, I will look into legal actions. I am trying to find out my options
