Willy was very straightforward in all his communications, quotes, and timing to complete our very slanted, high-roof, 2-story-house complete gutter installation project. Despite unexpected setbacks (some rain, co-workers backing out so that he did the whole job himself), he completed everything in a very timely fashion, explained everything he did, offered to do extra work for relatively cheap, and made everything look very professional and beautiful. He is very friendly, extremely reasonable, skilled, and diligent. I'd hire him again in an instant if another job arises. 5+ stars!
