Walter came out to quote my windows - an old house with horrid windows. I had a few other quotes but conflicting answers from other companies so I was feeling uncertain. Walter was direct, helpful, answered my questions, and even gave me his address so I could check out his windows on his own house as I was considering the same kind. The process was simple and quick. Within 4-5 weeks I had new windows. The installation took a day and the installer was very nice, friendly, professional, and cleaned up nicely. I absolutely LOVE my new windows - my home is a thousand times warmer, and I am completely happy. I would recommend Brock Doors and Windows highly.
