This is JanDevries's TrustRating, which is based on both the number of reviews JanDevries 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 JanDevries has been to the Kudzu community.
Very happy with the service. Had two other estimates and Dykstra offered the best price. They arrived on time , completed the work in a timely manner, cleaned up when the job was complete. Windows look great.
