My husband and I were having some issues in the basement that we thought were going to be very expensive to fix. We were expecting a few thousand dollars at minimum! We emailed Kefficient so that we could get a quote from them. The whole process was very quick. Mark came out and went under the house with my husband. He went over the crawl space top to bottom with him, explaining everything he was looking at or looking for. Turns out we didn’t have a big problem. It was a very cheap and quick fix. We appreciate the very courteous treatment we got. We REALLY appreciated the honesty we got from Mark. Most companies these days just try to take as much from you as they can. It was just a great experience all together!
