This is rbt778's TrustRating, which is based on both the number of reviews rbt778 has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful rbt778 has been to the Kudzu community.
This place has been there for a long time. They offered free estimates and the installers were friendly and efficient. Prices were 25% below big box guys and the products were the same. Highly recommend.
