Please be careful if you are looking for pluming or home services. Home Service Doctors are the worst and charging four times as others do for the same service. We had a very bad experience with them and our issue still exist after paying them big amount of money for the service. I wish I made a research before hiring them. when we complained, they sent another tech, he said there were three parts to be replaced in our water heater in order to fix the issue, which the first tech failed to do. They had a one year warranty that the issue will be fixed first time that they came in. After charging us with a huge amount of money, they recommend another huge money to replace the water hear itself. So I call it scam to rip your money step by step. A professional can identify the issue from the beginning and fix it. Unprofessional on the other hand do the job by guessing and trying some stuff step by step, in their case charging large money in each step then say opps we thought it will fix the issue.
