I've got a little stack of business cards that I'll be handing out. The whole neighborhood is in the same vintage of house that we are and we're one of the early adopters for replacing our windows. I think more will do so. Plus, Patrick who is a project manager himself and came to collect the check, gave me a list of all the things they can do and we'll be calling Aluminum back because of him. He marketed the other items/repairs outside of windows that we had no idea they did -- Patrick was on top of things.
I think the timeliness (they finished exactly on time) and also the follow-up when we did have a problem. That was really good!
