    The sale and installation personnel were well versed about the products that we purchased. There was also follow up by phone and email to make sure that we knew the date and arrival time for installation and also what to expect on that day.

    The sales representative was very nice and professional. He was knowledgeable and able to explain the entire process from sales pitch to installation to financing. During the financing 'paperwork' process, he had selected the wrong plan twice. Not only did he contact the financing company to correct it but he requested approval by his manager to give us an additional discount because of all the issues. The 2nd guy that came out to confirm the window size arrived on time & was professional. The installation team was great. They explained what their plan was. They wore booties over their shoes whenever they came into the house since they had to walk in the gardens next to the house. They cleaned up after themselves, using a vacuum!! When they were taking out the living room window it slipped and fell into the adjacent sunroom window (not being replaced) and gouged the screen. He brought it to my attention before I could mention it. They made sure to repair the screen before continuing with the remaining windows. Now that's being professional!! Definitely would recommend Replacement by Anderson windows for their quality but also the project team's professionalism & high standards to please the customer before I brought up issues.
