I have used this company 2 previous times and why change when something is done right so I hired them to replace my front door and 1 large window ( double hung) and a fixed side window. The saleman is your typical sales fellow but he does explain the quality, the process of having everything installed and the breakdown of costs pretty good.
The product is higher end on the cost scale but you get what you paid for. Excellent lifetime warranty, even with the sale of your house, it gets passed along to the new owners. The quality of the windows and doors surpassed what I was expecting and the service goes above and beyond what is offered in todays life.
The installers on all of my installation occasions are courteous, respectful, answers all questions ( as silly as it may seem) do a fantastic clean up job and also gave me a hand in hanging up curtains and moving furniture since due to a knee operation I was limited in what I could do around the house ( they even asked if there was anything else that needed to be carried or moved before they left)
I highly recommend this company and if I had anymore windows or doors to replace I would use them again.
