II was getting bids for radiant barrier, and found HPC in the adpages. There was a coupon offer, so I called for an additional bid. One of the owners, Jerry Christian, came to the house and meet with us. He was very profession, and discussed the benefits of the radiant barrier, and provided a quote which was very competitive. Based on the work, he also wanted an opportunity to quote on window installation which we were also getting quotes for. He came back in the evening so that he could talk to both my sister and I and gave a very good presentation/demonstration on the windows. Based on all the bids HPC was the most competitive, and their package gave me several "extras" at no charge. After some research, I decided to install windows, insulation, and the solar attic fan/vent. As I felt that would give me the most bang for me buck so to speak. David Christian, also an owner of the company, came back to do the final measurements for the windows before the order was placed. He was also very professional and knowledgeable about all their product lines. The day of installation David brought his crew, and arrived at the scheduled time. Work began with the window removable, and then the new windows were installed. Due to the time it took to install the windows, the solar fan, soffit vents and the heat, David asked to come back the following day to complete the outside window caulking, home envelope seal, and the insulation. They were there the next day, and spent approx. 3 hours completing the job. I am very pleased and excited about the windows and all the updates to make my home energy efficient. They went above and beyond in making my home not only attractive with new windows, but energy efficient. All the extras that they and their crew did was so unexpected and really appreciated!!! I can't wait to see my next electric bill!!! I am telling all my friends about these improvements and about HPC and the great job they did !!!! There were no surprises with HPC, they did exactly what they said they would do and more.
