NEVER use this company. I have never had an experience quite like this with anyone before. The lack of integrity is astounding. They started out quoting me a great price, but the work was terrible. Nothing was measured accurately, nothing was square, and they cut corners at every turn. In fact, they were pouring a foundation and my whole house would have collapsed if I had not switched companies and let them finish the project. My new company came in and had to spend two days fixing the terrible work that Concordia did. Concordia's workers then proceeded to steal materials from my new concrete company and then stole my money as well. I had given them a deposit for the whole project, and they won't call me back and made off with my money. I have heard of several bad stories of the pour quality work these guys do. DO NOT USE THEM. Low quality work that will cause problems and no integrity to admit or fix the problems they cause. They are crooks. Stay away.
