"He actually pointed out to me that I needed more insulation over the whole home as over a period of time it packs down. So I let him do the whole home as well as garage that I had originally wanted a quote on."

"Travis saved us a ton of money by giving us a straight answer on repairing the existing garage foundation versus tearing down and starting over with our detached garage. He certainly could have stood to make more money by just going with our original plan to repair the existing slab garage foundation, but he instead told us what he would do if it were his home. We really appreciate his honesty and will certainly hire CNT Foundations when we start over on this old garage!"
