Another Flooring Question

Pennyroyal's

Hi guys, I have a similar problem that was brought to my attn tonight. I am a general contractor in Louisville, Kentucky. Afriend has had an addition (2000sq ft) put on, 3 stories, hardwood floors, crawlspace (36") ventilated i assume. The hardwood was allowed to aclimate for two weeks mid feb., installed mid march, finished mid may. Buckeling is occuring on the first and second floor, mainly the first in the larger area spaces- not hallways etc. The ac was not turned on until after the problem started to try to change the humidity in the area.
Let's assume he has no moisture problem -but I have not inspected it. I am curious how his contractor dealt with the crawlspace and whether he put down plastic or some barrier over the dirt below to prevent excess moisture.
ok, what is the proper way to deal with this...on a new install is it reasonable to expect the floor to be repairable, or should it be re installed.
I will be calling MY flooring installer tomorrow but cannot reach him tonight, thought i would pose the problem here in the meantime.

First thing to do is get moisture reading where the floor is acting up and compare it to other parts of the house. Just because the wood sat in a house for 2 weeks doesn't mean it was ready to install. It did acclimate, but to whatever the humidity was in the unfinished house.

My guess would be either the subfloor did not have a proper moisture reading, or the hardwood in those areas were not fit to install.

If subfloor is to blame, rip it out, if it's the wood, it might settle down, or a resand could work if the wood is stable.
