I've experienced many of the same problems with my Pella Architect Series Windows and Doors, including cladding problems, seal failure, spotting on the glass, rotting wood among other issues. These Pella windows and doors were installed throughout my house in 1995. Problems with the windows began less than 10 years after installation. Pella refuses to acknowledge these claims. On my website, onlinelitigationdiscovery.com, you can see photos detailing the defects with my Pella windows and doors.
I've very interested in hearing other people's similar experiences with Pella. If you have had these problems with Pella, please go to my website, onlinelitigationdiscovery.com and tell me your similar experience so that we may educate consumers. Thanks for your time! -A. Bailey
