Our Project Manager said the stone for our fireplace was supposed to be delivered last week. He said he just received a call and said the stone we picked out will take an additional 2 months. Our closing date is this Friday but supposedly they just found out 1 week before closing the stone is 2 months delayed.

Thank you Wayne! I called to place a service call because I was feeling some draftiness around my fireplace. Wayne walked me through how to solve what ended up being a very simple and common problem - over the phone! Saved me the time and the money. I will look for ways to do business with this company in the future! Update - September 6, 2019 - I called in again today. We were having a difficult time taking out the glass in the fireplace to clean it.

We read the manual, searched YouTube videos, did everything but could not figure it out. So, of course, I called Wayne again. In five minutes, I had the glass out of the fireplace and a recommendation of what to use for cleaning it. Thank you again. I couldn't post a second review, but if I could they would both be 5 stars!

Stay away form this place! Ordered pavers, paid for them and had delivery set up. They called the day prior and told if we wanted them we would have to pay an additional $7,000. Avoid this place - plenty of other honest dealers out there.

I get unloaded here from time to time. The staff is always polite and try's to unload as fast as possible. Love hauling steel to this place!
