I dealt with Matt Ruskin for the proposal and scheduling and then Kyle and his colleague for the actual on site concrete levelling work. I could not be happier with the entire project from the initial proposal to completion and clean up. Kyle moved a number of slabs that had gone askew after many years and made them look brand new. I found the NexusPro® joint sealant also finished the slabs and made me feel comfortable that the would not allow surface water runoff to create the same problem in a few years. I would recommend working with them if you need concrete levelling services.
