I purchased all new premium Pella windows from Lowes because they claimed to have a team of expert window installers. Little did I know that this Expert team traveled for 2 hours one way to install the windows in my home. Apparently, they could not get work any closer to where they lived! They caused so much damage to our freshly professionally painted interior of our home. And then just said, we don't paint or fix drywall. I stated, you caused it! They did not repair it! In fact, they only installed 80% of the windows i purchased and paid to have installed by their experts! My home is now draftier than it was prior to spending nearly $70K on new windows! And, they refused to instal the windows handles and special hidden screens! Lowes does have the absolute best customer service reps and the worst installers. They have big hammers with long handles and they really use them! The house shook! I have about 50 hours in cleaning up after them! I am of the opinion the expert installers are actually a demolition team taking a break. Based on their actual job site work time, I think they gross about $250 per hour.
