A few days ago, another installer said he would float the 3.25" and felt that the heavy file cabinets would not be a problem since I have file cabinets in the middle of the room and furniture on the other side of the wall also to balance everything.
I'm missing something here Lynn.

What makes the one installer think the floor has no moisture issues ? Did he do any tests ?

Personally i would glue the 3 1/4"

Phila_2009, thank you for replying. I guess everyone pulls up my rug and padding and feels it and tells me they are impressed at how dry it is without doing any tests.

I had a new installer in today that was in out and out so quick which made me happy since others keep hanging around for hours and I can't get my work done.

He measured and pulled up the rug and put plastic taped down in several sections that he told me to leave on for at least 24 hours and then also looked inside the air conditioner vents and said it looked like the slab had plastic moisture barriers between slabs and that the water way deep in back of my fence is because they sloped it downwards to have water stay away from my house with a good drainage system. When we had Hurricane Floyd here about 9.75 years ago, roads around me flooded but my townhouse complex stayed dry including the roads and the road in front of my complex despite the townhouse complex being built on the preserved wetlands.

Another friend is coming by at 7 PM tonight with a moisture meter to test the moisture in the floor.

I was impressed with this installer who told me I only had to remove three of the 5-drawer 42" file cabinets from the room and make sure the other cabinets had the drawers removed and the two supply cabinets had the supplies out. He also wanted all computers and desk supplies out. He said his men could move everything as they worked and I would not have to empty out the three rooms as others have told me I would have to.

He also brought over samples of 5" wide GV Brazilian Cherry Engineered wood and GV Santos Mahogany and told me he would give me an installed price for these two woods and just in install price with the quarter round and supplies for the BR-111 3.25" Brazilian Cherry Triangulo Floors since he felt if I wished to go with that, he felt I should order it online for the inexpensive price I got and have the wood sit here for several days and he would install that.

Does anyone know if GV Floors is a good product? Is this a sawn cut like I was told it is? It is 9/16th thick and looks like a 2 MM real wood on top while the BR-111 has 3 MM on top but maybe 2 MM is all I need?

So if the floor is tested dry, you would glue the floor. Thank you for letting me know.

I appreciate your help. I am so excited that soon my flooring project may be done with. This 19.5 year old carpet is shot and I can't wait for it to be gone!

Tomorrow I will get his estimates and then make my decision on which installer to use and get this set up already so I can get back to concentrating on my work.

I will let everyone know what the moisture tests say since I was ready to either seal the floor first or float it and not just glue it down but now it really looks like my slab is dry.

I am happy to hear that you are moving forward with your floors. Be sure to post pictures when they're done.

XTek Moisture Detector Results today when my room is right now 43% humidity and 75 degrees in here since I turned off the air conditioner for 1 hour to see the results. I usually keep my room at 70 degrees to 74 degrees and the humidity levels from 35% to 50%.

The driest area near the windows in my family room that faces the woods in the backyard that is separated by a cement floor with stones and a fenced in backyard was 0.48%. In back of my desk was 0.48% in the living room area. In front of my desk by the windows near the outdoors was 0.64%. Two other places on the other side of my family room with the big windows (but the woods shade my back of my home and it never gets too hot and I usually have the sheer horizontal blinds shut to allow light in and give me privacy) were 0.60% humidity and 0.63% humidity.

Someone last year I hired to do the floors was all set to do them and changed his mind and told me I had to seal the floor due to where I live and never tested them. It really looks like my floor is dry.

Any professional opinions? It looks like the builder built a moisture plastic protector between the thick layers of cement that is several inches above the ground.

Kge9, Thank you so much for caring and remembering me. I am so excited that I finally found out that I have a very dry concrete foundation and I can't wait until I have chosen an installer so I can get this job started. The rug really now has to be removed since it is cut up in many places and pulled up to do the moisture testing.

Have you started your 5" wide Amendoim Floors for your den yet? I am sure they will be beautiful. I can't wait to see pics.

I will be sure to post pictures of my floor in all three rooms.

Phila_2009, if I decide to go with 5" (learning towards this tonight due to less seams with much longer boards), would you float the 1/2" thick, 5" wide engineered BR-111 Triangulo Brazilian Cherry Floors or glue them down without sealing the floor after seeing the moisture tests and knowing I keep my rooms always between 35% to 49% humidity and 70 degrees to 75 degrees temperature all year long?
