I purchased a complete home new premium window install of Pella windows. The install crew managed to ruin the freshly painted interior walls of our home, only install 80% of the windows, leave gaps in the trim to window surface almost large enough for a mouse to climb through, ruin every custom made supplied sill and signed the job off as complete! I must stress this contract was to replace All the opening windows in the house! I should have hired a bunch of 9th grade kids! They would have done a better job! After spending almost $70,000 on new Pella windows with installation, our home has more leakage around the windows than with the 50 year old windows! There is No pride in workmanship! Installers very frugal with insulating foam! I think they only used 1 can for 13 windows! Why insulate if the customer can't see it? I feel abused! My wife and I feel as if we were robbed. As far as the Lowes customer satisfaction warranty, they have Extremely good customer service representatives. However, the excellent service ends there. Not only does Lowes not honor their warranty, but I requested a different installer after the first day and was denied every request! I begged more than 4 times for a different installer! Lowes will not even respond to my phone calls! Promises are made by customer service reps and then never followed through. They got my money! I am nothing to Lowes except someone to ignore..
