"I have had over 45K of work or product from this company. I am writing this review as I tried to solve problem with the company with no luck. I went through BBB complaint and they took too long to resolve it and then told me that I was over the time frame. I had hardy siding, a 12x48 deck, 16 x 48 deck, 10 x 20 shed and they also installed my AC unit. The hardy install was subpar and had rework needed to be done at a later date. I had no issues with the AC install other than there was no asking where I wanted it, they just came and put it wherever they wanted it. I did have a housing inspector come out and inspect the front and back decks to document the deficiencies. The Back deck which is the 12x48 with covered roof I haven't had too many issues with even though the deck is not built to code. The back deck is also not level anymore due to the post not being concreted into the ground as per code. The majority of my issues have come from my front deck alone. This deck is 16 x 48 covered deck. There is no wood larger than 2 x 6 used. To start off with the deck sits approximately 5 ft off the ground at the furthest point from the house. There are approximately 40 4 x 4 post used on the front deck which are not sufficient but of the 40 only 6 are concreted in the ground. The deck spans 16 feet and they used a 2 x 6 x 16 beam to support the deck with a 4 x4 supported laterally not vertically at the 8-foot mark. If using on a 2 x 6 code calls for post more often so there are many 4 x 4 posts missing under the deck. All my post are on pavers. Some have come off the pavers. My deck has sunk over an inch on the North side. The joist span is not correct for using a 2 x 6. The joist are running 12 foot and shouldn't run that far. The only metal hardware that was used in the deck was the hardware to set the 6 outside 4 x 4 post in concrete. I would never use the business after finding out the amount of code violations in my deck and wouldn't recommend them."
