Thank you jerry_t for letting me know that tests need to be performed so I can ask the right questions to decide who I am hiring to perform the work. One installer who does not sell hardwood but only installs told my friend today, that if someone moves all the furniture and heavy file cabinets and makes the place ready for installing hardwood and if I had ordered the engineered wood already and acclimated it, he would install it for $2.50/sq ft as a floating floor. But then again, he has not done testing. I looked up some glues and some of the more expensive glues sound like they would have less moisture resistance problems. Another place about 1 hour from here would install the floor with glue for $2.40. Another place says $5.00 sq. ft including the best moisture resistance glue. Then there are all the other costs with the quarter-round and floor separating moldings for the three rooms that I am getting prices of $550 to $600. At this point I want someone who knows what they are doing. I do not want someone moving the furniture back in here and scratching my floor. This is getting to be overwhelming due to the office furniture. The family room will be easy to move the furniture back and forth. How should I clean the cement floor to get out any pee smells in case any pee has gone from the padding to the cement floor? The installers want $.50/sq ft to remove the carpet if I do not have it removed which does not include throwing it away for me. My brother told me last night that he would help me install the floor but he is more familiar with installing carpets and did not even know what engineered wood was. I want to make sure I do not have future problems and the job has to be done in about 3 days if possible for about 628 sq. feet so I can get back to work. I was told by one guy 6% waste to buy and another 10% waste to buy. I am pretty sure I am going with the BR-111 Triangulo Engineered Brazilian Cherry in the three rooms and doing tile in the foyer areas. I want to do tile in the kitchen since sometimes I get water in the cups in my dishwasher and it pours on my floor.

We have a cold crawl space under our flooring. Put engineered wood (hickory with no edge bevels) over a 1/4 inch cork underlay. Never noticeably cold and easy on the feet. My wife loves the floor. Warning: dropping knives or cast iron pans will damage engineered wood. We've done it! Also my wife knocked over a whole bottle of super glue on it and didn't wipe it up (she didn't notice it). That was/is a mess. Much scraping and still there are scars. I will have to sand and refinish the spots at least to make it look decent.

Its not the weight but the vibration of the machine that could loosen the joints, so the glue will keep it together.
