Several years ago I bought an older house. Among several improvements that I had to do was to eventually replace the old aluminum windows. I chose Simonton due to several factors. One was the quality in the design and construction. The other was the lifetime warranty, including glass breakage and owner transfership. The surprise came after the windows were installed. Outside noise I normally heard were suddenly gone. And inside comfort was better. No more cold drafts from my windows. I am looking forward to my power bill savings. Plus my Bay Window makes my living room look a little bigger. I wish I had the windows installed when I first moved in.
