We had a tricky and unusual situation, and Carl figured it out. He did a thorough analysis and did the repair efficiently. He communicated the problem and solution to us in understandable terms. Our problem has not recurred. Nice job, Carl, and thanks.
Contacted Haller due to flooding in our basement. Was able to get appointment the same day. Eliezer was very professional and quick to figure out the source of the flooding. Quoted us the cost and what is needed to be done. He quickly went to work and unclogged our pipe that was causing the problem. Would recommend Haller for their 24 hour on call service and Eliezer for doing a great job.
