    A couple of places the caulking has settled in just a little, not much but I would like them done. I spoke with the Manager and he advised me that someone would come by and fill them in, so far it has been about three weeks and no one has come by. Yes, I could do it myself but I don't know the type of caulking they used plus the warranty if I do this? Otherwise we are extremely happy with the windows, we noticed the difference immediately, we are really please with the windows and the installers.

    Great experience -- no pressure consultation, great installation. I could tell the installation team cared about their work and the service they provided. Will be a repeat customer.

    We had the same crew from Colorado Springs install our two sliding doors and then 8 weeks later install our windows and they were a truly outstanding crew and individually. They worked hard and efficiently and neatly and the installed windows and doors are perfect. Vince Capucci was excellent in the sales cycle. The product and the entire process were excellent. We could not be more pleased.
