Isbir Construction took down and rebuilt our existing Versalok block wall that was constructed previously by another contractor not long ago prior to us purchasing our home. The wall is fairly large, has a bend and also contains lights along the driveway portion. The previous wall was leaning, had no drainage system, had gaps between blocks, was not level and was not built to Versalok specs. The wall became unsightly and a potential safety hazard as well. Mike Isbir gave us a great estimate and answered all of our questions and concerns immediately and honestly. The wall looks incredible NOW, is structurally sound and is built exactly as specified. Mike Isbir and his professional crew worked diligently, took their time and made sure not one bit of detail was left out during the build process. People we don't know stop all of the time and tell us how great the wall looks. Bottom-line: I would recommend Isbir Construction to everyone who is looking for the best work! Period!
