I contacted Premier Windows through Angie's List. I sent an email and was surprised that they called a few hours later. They set up a time for a consultation and arrived on that scheduled day.
The representative, Tony, was very professional, thorough, and knowledgeable. He went step-by-step explaining the process, the pros and cons of which product to use in our attic and didn't mind when our Corgi sat licking his leg for several minutes! They were great, and I will definitely use them again.
I cannot recommend them highly enough and encourage everyone to consult with them before choosing a home improvement contractor.
