Happy that Feldco stands by there warranty. Purchase a home with 3 broken windows and was able to get the glass replace in them under warranty really saved me a lot of time and money. Our technician Sil came out to measure the windows and few weeks later came back to replace the broke panes. Sil and the customer service did amazing job.
