We had tile installed everywhere but the bedrooms when we built our house. The tile work was done by a company in Sumter Landing and we had a number of areas where lippage was a problem.
Our lippage problem was a nightmare or I should say dealing with the tile people was. Regardless of how much lippage there is, it is always a trip hazard, especially where older people are concerned,
because many older people do not lift their feet enough when they walk.

If you haven't paid for everything -- DON'T! No matter what you may work out, don't pay until you are completely satisfied, not matter what.
Good luck. You'll need it!
