I had a home built 3-1/2 years ago on a concrete slab. To date, my hardwoods are discoloring and look as if they are 25 years old vs 3-1/2. The concrete slab area where I have carpet layed has mold spots and is very cold to the touch (temp outside is around 85-92 degrees fahrenheit) My dogs are becoming attracted to the mold/moisture problem and have begun urinating or marking the spots which is causing more problems. I have a 10 year structure warranty on my home. The builder is claiming that the problem is due to pet urination only and has never heard of pets marking areas of a concrete slab that present issues. I need new flooring due to the pet problem; however flooring contractors tell me I need to address the foundation issue prior to changing out th current flooring (carpet and hardwood that it pre finished. What questions should I ask the contractor about the pouring of the concrete slab (on a day which it was raining) and the fact that when I have pulled up the carpet and floor matting there appears to be no application of sub board of any type or any vapor barrier present. Just plain old concrete. Should I pay to have the calcium chloride test performed? Whom should I contact. Lost and getting the run around...I have more photos; however it will only allow me to upload one at a time
taping a 2' x 2' piece of plastic down to the floor & 'see' what moisture collects in 24hrs,,, we've successfully solved this problem by installing acid-stained floors,,, but that's a personal design issue,,, as a plus, they're 'pet'proof' :-)
We are going through the same thing with our house. Hardwood started turning brown. When floors were pulled up we discovered we had a huge mold prolem. We had the moisture test done on the slab and it was 30-60%. The normal is 12-16%. We have been fighting with our builder getting them to cover damages. We have a huge slab problem. It sounds like you have the same problem. We started with a moisure test, then mold testing. The builder did not want to do these test, but after we gave them results they are finally are doing something about our huge problem. We had to get an attorney to help us with the fight because the builder just wanted to cover up the prolem instead of correcting the moisture problem in the slab. We now are having an engineer to come out to reccomend solutions to correct the problem. Our house is only one year old. Do not let them jerk you around!
