    The windows they sell are good quality windows. The installers are not great. As I am doing new…read moresiding, I am finding the window installation not sealed. The sheathing under one of the windows was wet, and ants had gotten into the insulation. So in addition to siding, repairs and extermination is required. I have asked for service, replacement on the window wrap. That request was 6 weeks ago and the only communication was 'send a picture' which I did and they said they got it. Why can't they install a drip cap correctly and make requested repairs?

    I paid 5500.00 for a single window in the house and when problems were encountered I was left…read morewithout any communication while emails, phone calls and even a BBB complaint went unanswered. I'm not sure how they get an A + BBB rating when they get contacted with a complaint and even do not respond to the BBB. So now I have a window that has wood freezing and turning black when temperatures drop below zero. The blackness is the first step towards rotting away, and `it comes from an inadequately insulated window frame. I know it is not from moisture in the house as I have monitored it and the wood gets so cold it freezes. Since early Spring I have attempted to get someone out to repair it, and one time someone even promised to correct it after a house visit, but then communications were lost again. It's not just that the 5500.00 window will eventually need to be replaced again, it's the fact that the company simply doesn't care about customer service or honor any type of warranty work. The window is a Lindsey window and they only called one time as well then never heard back. Terrible backing of what they sell and install, and apparently terrible quality of the product. A window like this should last 20 or more years and this one is bad at five. I eventually gave up communications and wrote the BBB, and today I get an email that BBB letter to Minnesota Exteriors was never answered. Again, no response! I would not recomend them to anyone for any type of work just because they don't care after the sale is over.
