Had my home insulated ( with cellulose ) by pipe works top to bottom along with attics. Prior to doing this my home never felt warm in the winter and had huge drafts on the first floor. Heating bills with an all electric house was out of control. Thanks to pipe works and their hard working crue I can honestly say my house feels much warmer. I am shocked since this problem has been going on for almost 20 years. These guys worked hard and believed in what they were doing. Showed up on time and did a clean and tighty job. No complaints. I plan on converting to gas in a year or so and will go through pipe works again. You get what you pay for...highly recommend.
