I wanted a Bay Window and was debating whether I would go with a big place like Home Depot or Lowes. I got a card in the mail from Topline and they offer a free estimate, so I called them. They sent a rep within an hour. They sent Tom to my home and he sat down and spoke to myself and my husband. As he answered our questions I felt, wow, this is this guys business and he knows his stuff. He made us feel confident in his experience. To be fair I also spoke with someone from one of the large stores and the sales rep was not able to answer our questions nor could they give us a price unless we paid to have someone come to our home, which I did, and still was not quoted a price. We decided to go with Topline. We did not regret out decision. My father came to see the window(he's worked in home repair) and he said these guys did a great job! I love my new Bay Window and am waiting for them to install my custom made door next. I just might get my siding done with these guys next year. Great professional work.
