Terrible! After reading the last review and just getting off the phone with VerHalen, let me say, this is the worst customer service in the business! I, like the previous review, have black mold growing on my new windows again, and they said the same thing..a year ago. Humidity and windows were fine! It is amazing to me that my bathroom is right next door, same window and same exposure, blind is always down and my kids take 20 min. showers and have NO mold in that room, but in a bedroom where no one has been for 1 year AND the window treatments were removed, guess what's back! MOLD! Called the installer and they want Pella to come out. Pella wants a guarantee of $82 trip fee-Uhh, what #+#**? So after going back and forth, the installer is gonna pony up for that but now they say they have no one until 3 weeks to come look at the window. REALLY??? you gotta be kidding me? I have a son coming home from college to occupy that room, and he has asthma. Do they care? No! Can they please send
