On July 9 2009, I purchased Schon Quic Clic Carbonized Strand Bamboo flooring from Lumber Liquidators (LLI) for $5000. Installation was $2000. After months of comparative shopping, the sales rep had convinced me that this was the best product for high rise living. It was 10X stronger than the teak wood I had previously decided upon, it installed well over concrete floors and it had a 30 year warranty. I asked if there was any problem installing it during the summer, due to the extreme weather and was told that I only needed to have the wood delivered 3 days before installation so that it could acclimate. When I inquired whether I needed to have the air conditioning on or off, I was specifically informed that the product worked well in a wide range of temperatures. Within 18 months, the surface of the bamboo flooring began to raise and crack on 40% of the installation. I called LLI and there acted very concerned. I mailed then a disclosure statement and photos on January 5, 2011. They sent an independent inspector from All Flooring Inspections, who noted the cracking throughout my home, including on the extra wood, still in the original packaging, which had not been installed. LLI sent me a letter on March 2, which states, "Cracking is indicative of the wood reacting to its environment. Future cracking can be managed by maintaining correct environmental controls. Temperature should be maintained at 60º to 80º and humidity 35% to 55% during installation and throughout the life of the floor." This is what is stated on the Schon warranty, which LLI sent with their letter. LLI also states that they "will take no additional action regarding this matter as this is not a warrantable claim." When this product was recommended to me for my condo, I was specifically told how well it would work in a high rise. Even if I were never to open my windows or the door to my balcony, it is impossible to control the temperature in a high rise, much less the humidity, because there are vents in the kitchen and bathrooms that circulate the air throughout the building. During the winter when the heat is on, the humidity is much less than 35%. In the summer, the average relative humidity in Chicago is more than 70%. If the conditions of the warranty can never be met in Chicago, should the sales rep suggest this product and tell you that it is a better choice than wood? Hoping to spread the word to prevent others from making the same mistake.
