$40,000 dollar concrete job to include a egress window which is now installed and a 1,500 sf basement that I removed 2 layers of concrete and dug an additional 5" lower per customers likes. I require 1/2 of total job cost up front. He paid me only $8,000 up front and said he was going to pay the full $40,000 up front.. he paid me total of $10,000 then offered me $5,000 to pack up and walk away for no reason. No reason at all. I have more than $15,000 dollars into this job and only reason work could not continue in a timely manner is because the job was out of money. If the $20,000 or like he said he was going to do and pay total $40,000 up front the job would have been done. This total did not include the additional and labor intensive additional digging and cutting through 20" thick limestone for egress window. I'm literally out money from this job and lost 2 other projects for different customers totaling $62,000 just in loss of other jobs not including the losses on the project I speak of.
