    Olshan Foundation Repair

    I used Olshan to level my house in 2022. Their salesman came and looked at all my concerns inside,…read moreand the proposal for repairs was made. Three stablizing jacks were proposed and I was told it had a transferable 25 year warranty. After thousands of dollars hiring them, they came and placed the jacks. To my surprise, the foreman was bringing out the other, much larger jacks when they were finished. Instead of adjusting the jacks I was never even told were already there, I was sold on these. I proceeded with the renovation of tens of thousands of dollars, I noticed cracks in the new tile above where they placed their "much better jacks." When I called, I was told I had a year warranty and it had expired. No solution was offered. Other companies wouldn't touch their "subpar" equipment. Fast forward a couple of years, their thousands of dollar proposal wasn't even the solution to the problem to begin with, only a small part, and now ineffective. Their jacks weren't stabilized and not even touching the beam. The small concrete pads they placed them on, which were merely placed on top of the ground, had sunk into the ground with the pressure and were doing nothing. They removed jacks that were only needing adjusting and put it a failing system. What the salesman (inspector) says when he's here and what this company actually does are two different things. Completely dishonest!!! Now, I've had three more companies look at it and every one of them found the actual solution without being told what the one before them proposed. I may add it was NOT what Olshan proposed for years ago. I wasted thousands on their overpriced solution and lost tens of thousands more because their system failed after the renovation. If you like starting over and throwing your money away, go for it. No integrity!!!! Beware!!

    They inspected my duplex and scared the buyers away. I had an engineer look at the property and…read moredeclare that there were no structural issues?
