A device for leveling and aligning tiles and method for leveling and aligning tiles are disclosed. In one embodiment, the leveling device includes a body and two spaced and parallel strip members extending transversely from the body. Each of the spaced and parallel strip members extend to the front and rear of the body. Two opposing lateral open windows are formed in the body. A breakaway section is defined along the body. A wedge device is provided for penetrating one or more of the two opposing lateral open windows and exerting a force on the tiles for leveling them relative to each other.

A tile aligning and lippage tuning system that uses a single piece base and strap which is designed to break away from the base when sufficient pressure is applied and is also designed to stretch along a thin wall region before separation of the strap from the base occurs.
