Corona Hardwood was very easy to work with. They didn't do the installation, but I bought the materials there.
I've used them for two different projects, one a few years back, and one more recently. The first time I went into the showroom, and they were very friendly and helpful. The second time, I was able to send my installer in to get the materials. This worked out great because I was out of state at the time and was able to do a lot of stuff through email. I highly recommend Corona Hardwood. Five stars.
