I installed 29 Harvey Windows in my home and for a few years they were fine. Then moisture began appearing between the “sealed” panes. I contacted the company and was told i was out of warranty. OK, my question is why spend thousands of dollars on replacement windows that only last a few years? Shouldn’t high quality windows last at least 10 years? I had Anderson windows in a previous home and they were fine after the 15 years I lived there. If I had it to do over again I would have replace my windows with either Pella or Anderson. Don’t buy Harvey!
