Great

When I called Klaus and Sons, Heather answered and was so friendly, courteous and helpful! She listened to my tale of woe about the leak and she scheduled an appointment the next morning. She later checked with me about a minor schedule adjustment with Wes, who did a fantastic job fixing the leak!! I hope I don't have future plumbing issues but when I do, I will call Klaus and hope to speak to Heather!
