We bought a 1960's ranch and needed to have many of the original single pane windows and two sets of French doors replaced with sliding doors. We selected Imperial Home Improvement for the job based on John's professionalism, communication and pricing. I'm always impressed when email correspondence is well-written and timely - John's was both. In addition, he returned calls when I had questions and always worked hard to make sure I had the information I needed prior to making a decision. We selected the Simonton brand and couldn't be happier. They are solid windows - energy efficient and very nice looking too. During the installation John and his assistant worked hard to make sure we were satisfied with everything. I highly recommend Imperial Home Improvement, a competent, trustworthy and highly professional operation.
