the company is terrible!! the project manager was horrible he would say something and then maybe 2 days later he would do it. They didn't pick up, didn't finish the job until I noticed the obvious in which i should have never should have had to tell them to finish covering the nail holes. They tried to get away with copper clamps with drywall screws on the outside of my house, which would have only meant they would have had to come back a year later due rust stains. I didn't pay over 10k for a package of 3 dollar copper clamps. DOn't use the company.
