I want to thank A-1 Concrete for solving my problem with a front porch slab that held water and caused major damage. This water seepage caused a mold problem to my finished basement. A-1 slanted my porch and sealed the separation caused by the standing rain water. A-1 Concrete was very professional and finished the job as discussed. They also came back later, after I noticed a portion of the porch had a small area that was missed and was not sealed. After calling the company, they came back and finished the job to my satisfaction. Great job and I will definitely used this company again.
