I had a leaking sewer pipe hidden under concrete slab. The water was coming out off the floor when draining water. I removed everything including the dish washer and opened up the drywall. They came over and took their time to evaluate, including flushing sink water repetitively, to see the water came out repetitively, dug outside foundation for 3 minutes, visually inspect everything again and again, call his boss, wait outside for his boss for at least 20 minutes, call the HOA manager (because it's their friend), and wait outside for the HOA manager for at least 20 minutes. In the end I was charged around $190 for the so called evaluation (because they spent 1.5 hours for...I don't know what they did) and then given an estimate of $650 to really find out the problem was. Note that $650 did not include the fix or any other potential damage. What's worse was that, after $190/1.5 hours of the so called professional evaluation, they told me it's a cast iron pipe running perpendicular to the wall, while in fact it's a ABS pipe running in parallel to the wall. If you are in a state of emergency, have a lot of money to throw away, and know exactly what to be done to fix your problem, you may call them. Oh wait, you can't call them because they will let you wait in order to charge you more thus can't solve your emergency problem. Okay, maybe if you have a lot of money to throw away, and know exactly what to be done to fix your problem, you may call them. For example, if you want to rip out our golden toilet and throw it away, I think VDH is the company you're looking for! Otherwise, please don't rely on them doing the trouble shooting for you. Because they are going to waste your time, deliberately, and money, also deliberately, and still give you the totally wrong diagnosis.
