Several rooms at this client's house were badly in need of leveling. Largo Green Inc. (LG) used wood blocking, and even installed beams where needed. The 2 upstairs bedrooms were refitted with sturdy plywood flooring. The kitchen below also needed leveled. The laser level LG used showed some areas as much as 3-4" of depth. LG applied Level Quik, both upstairs and down, spread over several layers and days.
