""Multiple projects involving deck, siding, outside trim, soffits, chimney, light fixture, and carpentry. The pricing was very reasonable, there wasn't any waste (as some materials were able to be re-purposed) and they did an excellent job. They showed up on time, were very efficient, did great work, and thoroughly cleaned up upon completion. Gary is very accommodating and responsive. I recommend him highly!!!!!"
