Installation crew of Dan Danner and Partner did a very good job and were very professional at all time. I did have to call and request service as 4 windows were of concern. Roland came this same day and made some adjustments and windows work very good now. I would suggest that the installation lead person take the homeowner and do a walk thru and demonstration of each window installed. It would be good business and reveal the items which needed attention. I would certainly refer Home Solutions.
