Perma Jack / Valentine Corporation 

History of Valentine Corporation - General Engineering Contractors - Construction Excellence Since 1964

With Valentine Corporation's expertise in "Unusual and Difficult" projects, it was only fitting that they became a franchise company of the Perma Jack System and added an additional division to the company in 1978. The Perma Jack Division specializes in foundation repair, underpinning, leveling and stabilizing on both residential and commercial buildings.  We have used the Perma Jack method for foundation stabilization and house leveling since 1978 and are the only foundation contractor in the S.F. Bay area to do so.  To learn more about the Perma Jack method to correct foundation settling and house leveling issues with very little disturbance to the tenant and at a very competitive cost, click here
