"This company customer service skills and communication are horrid. I had no problem scheduling an appt for someone to sell me on their business but they day the work was to be done, I had to call them 5x for ETA checks on their techs. They were supposed to arrive between 9-9:30am and did not arrive until 1:15pm. Each time I called about the tech ETA, I was told by the receptionist that they would check and call me right back, they never did. The 5th time the receptionist said the supervisor of the techs said they were dispatched to my location early that morning, but he does not know where they are or why they did not show up. The receptionist called back later to say the techs should arrive by 12pm but they did not arrive until 1:15pm. When the techs arrived, I found that their supervisor told them to do a job prior to coming to my location. I was supposed to receive a lifetime warranty for the work done and after 4 calls I still have not received it. Poor customer service."

"I highly recommend Lux Renovations/Owens Corning Basements for refinishing basements. The initial consultant was highly professional and it never felt like he was a ‘salesman’ with high pressure tactics just trying to get his commission. I have never refinished a basement before and assumed it would be the same as any other room in the house but I felt extremely reassured about the materials and methods used to keep the basement in the best condition as possible. When it came to the instillation, I cannot speak highly enough of the people that made it happen. They were prompt, hardworking, considerate, and there was never a moment we were concerned about having people we didn’t know in our home. The results are wonderful. Our basement was feeling like a dingy place we just put stuff but now it is open, clean, and an enjoyable place to be."
