"August 2, 2017 I felt that you should know that your whole process from sale to installation went very smooth with no problems. Mike Pelone was right up front with everything, honest, pleasant, helpful, professional, made recommendations, and was concerned to make sure that your company could offer what we wanted and needed for the house's front awning. Kevan in your manufacture/installation department was very helpful , professional, and reassuring for some of my questions i had after a few days (my after thoughts regarding the awning and its structural strength). Mike & Dave (your installers) were very honest, pleasant, professional, and concerned to make sure that the installation was correct and to my satisfaction. I was happily surprised how Mike made sure that at important steps in the installation that he used large level and plum-bob to make sure that everything was put on correctly and was level (both vertical & horizontal). Mike & Dave also made sure that the additional panel of siding and the small pieces covered the areas that i discussed with Mike Pelone & with Mike when he had confirmed Mike Pelone's measurement, etc. There is no question that Mike & Dave (installers) paid attention to all of those little details that makes a Big Difference in finished product and very satisfied customer." - John K. Easton, PA

"07-25-05 RE: Steve's Crew Dear Jeff, My wife & I would like to take the opportunity to compliment Steve & his crew of Richard, Andy, and Shane. We were extremely impressed with their workmanship, customer skills, and attention to detail. We have been in the process of re-modeling our 25 year old log home since April, and have had a number of contractors come & go. They could not compare in terms of the professionalism & journeyman skills of Steve and his crew. You could tell these men take personal pride in their trade, which our home now reflects. They are in effect your best marketing tool when it comes to customer friendliness & quality workmanship. I hope they are well compensated as I intend to recommend your company by word-of-mouth in the future. Hope you & your staff have a profitable 'o5." - William C. Danielsville, PA
