Lise Wenzel (owner) of Alternative Floor Designs came to our home as we were shopping for travertine flooring. She sold us on her service and pricing. We purchase all flooring through Lisa and spent approximately $40,000. During the 1st year the travertine began cracking in a straight line along the seams of the subfloor they installed. About 30 tiles had cracked. She came to look and did not want to take responsibility but tried to put it on the tile manufacturer. The tile manufacturer sent an independent expert out to examine. The results were a improperly installed floor due to the thickness of the subfloor. Lisa had one of her employess fix our tile. It all cracked again within the next year and stated that she would repair it. She came to repair and stated that her employee did not do what she told him and that is why it cracked again. The work she performed has not cracked and we are satisfied. Another seam that was not repaired has cracked with about 12 tiles and I have called for Lisa approximately 8 times over the past 2 months to try to get her to fix or at least talk about. She will not return any phone calls but had her employee inform me she would fix but I have to pay for it. She admitted to faulty installation, she promised to fix issues but refuses to floow through. My next step will be legal action should she not be willing to honor her obligation.
