We called A-1 with an immediate unknown problem with our septic system. They were able to rearrange the schedule of one of their technicians and he came out that day. He was able to diagnose the problem, find our hidden septic tank and pump it out that day. He also pointed out a situation with the tank that would have quickly become a problem had we not decided to fix it. They were prompt, courteous and professional. I will use them again.
