Our basement came out great! The process was fast and stress free. If we had any questions or concerns they were addressed immediately. Our basement was ready in 3 weeks.
I’m very pleased with my new basement from Owens Corning. I was assigned a project manager who was very professional and easy to communicate with. The crews who came through kept me informed on what was being done and the timeline for the job they were doing. I love my new basement.
I don't regret a thing with this company. Amazing team that worked quickly and were very helpful throughout the process. I can't recommend this company enough.
Owens Corning was so great to work with! They were very transparent on the process and steps along the way, so I knew what was going to be going on and who was going to be here. The people that were working on the basement were curtious and asked for our opinions along the way to ensure we were happy with where things went. We love the look of our basement and are excited to enjoy the space!
Really impressed with their work ethic. Showed up on time when they said they would. Project finished ahead of schedule.
