I had three windows replaced. The initial contact and measuring was quickly after I made the purchase. I was told it would take maybe six weeks to have the windows made. It actually took less than three and we quickly decided on an installation date. Due to another project the installer was a couple hours later than expected however he called twice with updates. In the end the project may have taken longer than expected but he not only finished it on a Friday evening going into Labor Day weekend but was joined by a second person to help speed it up. I appreciated the professionalism, willingness to finish the job right and not fast and and pleased with the product.
