Horrible Company to work with. They never came back to fix the problems that they had created and they will keep pushing you off by saying “they will come by next week”.
Brand new cabinets falling on our feet for bad sliders. Stove caught fire from not being converted to propane gas. Tiles have cracks everywhere. Possible Electrical wires touching as fan switch turns on lights and light switch turns off fans. I have contacted them multiple times and no response. Water is building up in my garage from bad concrete slope. Horrible company!
