wood flooring installed without proper acclimation
We are building our first home and were shocked to find our builder installing our 3.25" red oak floors in 80 degree, 65% humidity weather without properly acclimating the wood. Our house is still open to the elements and without a working HVAC system. We spoke to the builder and he states that they measured the humidity of the flooring and the subfloor and since they only varied by 2%, they went ahead with the install. I expressed my strong concern regarding the boards expanding and contracting, but he told me my concerns were unfounded. He did suggest that we could have our lawyer draft a contract which states that he will replace the floors should any problems arise. We plan to do this and were hoping to get some advice as to what specifically should be include in this contract. My concern is that I will find the gaps in the wood unacceptable but that the builder will say that the gaps are within the normal range and not related to the install (when they in fact are). I'm very frustrated by all this and greatly appreciate any and all help.
Thanks in advance!
