I am a frequent flyer with Premier Windows, and just recently, they installed new front doors for us. About two years ago, they installed some new windows as a subcontractor, which also went well.
This time however, I am having them redo and insulate my attic. The sales people, are as usual, on time, friendly, and are making this an easy project for me and my family.
Along with their contractors, the guys who actually do the work we pay for, their whole crew who comes out is very professional, on top of their game and has never done a job for me that isn't perfect. If you need new insulation, you should definitely call them and find out what your best option will be.
