Pinnacle Energy was very informative and professional. Installation for almost a dozen windows only took a few hours and was done the same day. Ask for Eric as your sales rep, and tell him Farid sent you :)

We were very happy with the installation of all of our Windows. Everyone worked very hard that day.

Pinnacle Energy replaced our siding and gutters. The house looks great! The workers were very courteous and did a great job cleaning up. The work was done in a timely manner and completed as ordered.

We had our aging roof replaced through Pinnacle Energy recently, and are extremely pleased with the outcome thus far. The 50 year warranty on the material and labor adds great peace of mind, particularly with the manufacturer's backing (and the transferability to the next homeowner). The workers were professional and cleaned up fairly well after the job was done--barely a trace. While Pinnacle may not be the cheapest group in town, their value is well stated in the quality of workmanship and materials used for their jobs.
