Tri-Star did a great job salvaging our back deck from some bad stain we bought last year. Then Don cleaned our front deck also to get ready for new stain. He cleaned the greenhouse glass and foundation. Also cleaned the roof, it has not looked this good since we built the house, Don is super easy to work with, he did high-quality work, we will have him back in the spring to finish the decks. Excellent work/fair price, The highest recommendation!
