Replacing windows is definitely an investment. We're going with Renewal by Andersen. We're replacing about 25 windows; some will be the same size and some will be new sizes. We're also ordering some french doors.
They have a nice showroom on 1st Ave S- south of Safeco Field. We've compared different companies, some independent and some part of national companies. Renewal by Andersen is locally owned and part of the Andersen Window company.
I recommend to do your homework on warranties and services. Renewal manufactures what they install so they know all about their product. They have a special going on right now. Check out their company website www.renewmywindows.com.
