I am a customer in Charlotte NC. We had some work done by Olshan more than a year ago. 4 piers and some crawlspace work. When adjusting the 4 piers placed under the foundation itself, they raised it too high. It cracked my walls and almost broke the windows. When they hired someone to fix it, they wouldn't pay him to paint, only drywall the cracks that they created. I had requested when the last warranty work was done, that a concrete pier be mortared. Instead it was removed and a loosely fitting jack put in it's place. I mean, just feel free to do what they want and ignore me guys. When their man came out the last time, he pointed out some mistakes himself, that included the improper use of shims. He said he would fix it, but never did. When I called, no one ever called back. This time, I needed some adjustments and some more work done, so I gave them a call. Figure I might get some of the stuff they missed last time while they were there. Since I said I knew there would be a charge, someone called me back. Imagine. But they no longer work in Charlotte, I called another company that does. The 4 sunken piers seem to be fine, but the work that they did underneath the crawlspace has not held up well. They had to readjust it about 4 times themselves during the 1 year that they warranted it. After pointing out the problem areas to the person from the new company, he explained the errors that their installers had made. His observations made a lot of sense, and I started to realize even more so, what a shoddy job they did. i.e.: On some of the concrete piers under the house, there are as many as 8 to 10 metal shims stacked up where there should be treated wood, and a couple shims to cover that large of a gap. And, there are jacks used in areas that needed concrete piers, and some of the concrete piers they did install are dry stacked, no mortar at all. And 2 X 10s were not used where they should have been. Basically, this would never pass a housing inspection. Whether or not we'll file a suit, after having to pay another in the event they do not do the repairs, is yet to be determined.
