Olshan installed 36 cylinders in 2001. 2003 house shifts and caused pipe break 10 feet under home (rear bathroom). 2006 house shift again cause pipe break and pipes re-routed. 2010 called representative out and he lied on observation of movement ( lot of cracks re-open and new). 2011 called representative out again and he gladly identified there was movement because there was much damage and major plumbing damage in both bathrooms. The plumbing repair in 2003 has broke again. After much research the major house shifts due to faulty cylinders which Olshan is aware they have has caused much damage to my house inside and out. Olshan will not comply to the liability of the cylinders shifting and not holding up. Due to the lack of response to correct the problem, the damage is great and all because Olshan has handled this very unprofessional and without proper etiquette. Olshan wants to re-lift my home without fixing the plumbing problem that their cylinders has caused damage. Olshan said the cast iron pipes broke and caused the house to shift. 2003 the rear bathroom pipe was replaced 10 feet under my home which included the bathroom by 5 feet. It is evident that Olshan is liable and refuse to act on their responsibility. I have posted a video on You Tube stating..(Olshan has screwed up my home do not let this happen to you). You can see the visible damage for yourself. Thanks!
