We added a large covered patio across the back of our entire house that included stone floors, fire pit, fans, lighting, a stone walk and slab for a hot tub, and all electrical needs. We also had then install gutters around the entire home, and repair to our sprinkler system.
This company's professionalism and workmanship was excellent. The only negative was the total time it took them to do the job because they are so busy and they had to shuffle their work crews around. They also would sometimes commit to show up on at a certain time on a certain day and then not call and not show. Other times they would show up a day or two later than scheduled and sometimes they would show up unannounced. I would not hesitate to use these people again because their workmanship is excellent and they back their warranty 100%, but I would put a committed completion date in the contract including financial penalties if they did not make that committed date.
