We heard about House Smart from our neighbours, so we had their sales guy over. He went through his pitch and it was more expensive than we thought, so we had to think about it. When we called him back to go with half the project, it was like a brand new conversation- he forgot what we talked about previously. He did end up honouring everything we discussed previously. Then we had another guy come to take proper measurements, and eventually the installation crew. It took a while because we had a window custom-made for our kitchen. When the crew did the installation my husband was around and inspected their work. First, they forgot our custom window (which is the whole reason we had to wait so long in the first place). The boss ended up driving it out separately that same day so it could be installed. They also also forgot locks to the screen door and some other little things with the other window, which was apparently due to a junior worker on their team. Overall, I like our sliding glass door, but not a fan of their windows in general because of a weak safety on them. The custom window, however, is fantastic! It was much more expensive, but worth it. That's the way to go, if you have the money for it. I think we'll seriously save up in order to get all of our other ones custom too.
