My wife had been after me to have all 16 of the windows that were original to our 25 year old home as well as replacing one standard door with a new one and replacing French doors with sliding glass. Finally, I relented...and I couldn't be happier with the choice we made with Mark and Windows Depot. Mark was the only person who made the sales pitch for our business that I wasn't able to meet, so I was somewhat dubious when my wife said she really liked Mark and what he had to say about the Windows Depot product - and the cost was extremely competitive with the other 4 companies we'd gotten quotes from. But when I read the reviews I thought, okay, if things went South, well, like any self respecting male, I'd blame my wife. As I said, I couldn't be happier with Mark, the Windows Depot product or the installation crew of Marcus and Gabriel. Speaking of these two, not only are they great guys but they were on time, knowledgable, professional, courteous, respectful of us, our pets and our home. I was home for two days of the installation and it was refreshing to see how dedicated they were to providing quality service while installing a quality product. The installation was completed today and neighbors are already asking for Mark's number saying, "I want what you got!" I'm the Quality Manager for the company I work for. I feel confident in saying I know what it takes to meet or exceed customer expectations. Mark, Marcus and Gabriel not only met but easily exceeded my expectations. Thanks, guys!
