Louise made herself available to provide the measurements and was good about being available to help us pick out the floor. The installers (Wilmer and team) were fantastic - on time, respectful and made sure the flooring was put in place 'the right way' .. (we had some leveling issues they called out and fixed before install). We had pre-finish in the entry and kitchen prior and never had any issues. My COMPLAINT is that we were not given more advise on the floor we selected and potential issues that can arise.. As an example, designer floor and interior folks should have told us the impact heavy items can have on the wood floor - for example -- we had no idea the floor would create 'indentions' due to the couch..-- assuming wood floors could support the couch weight w/out having to use something under them. We found out the hard way - and that stinks because there's nothing we can do about it. It makes me question if we got a great price because we got an inferior quality product. (on sale). We had the options of selecting 3/8"", 3/4"" or solid.. Per the advice from Louise, we chose 3/8"" .. kicking myself as I should have chosen a solid... Like the floor overall, but disappointing service since we were not give more guidance and advice prior to install..
