We bought this house two years ago but windows began fogging up in between the glass panes. I was very skeptical choosing replacements and asked for recommendations. Like my neighbor said, Window guard was a bit pricier than others but it paid off. Installation was on time, top notch and they cleaned everything up. Windows have a very solid feel - like doors in a Mercedes. It’s been only a few months so we hope they will last, have no problems so far.
