I had a horrible experience with this company.
I contacted them via email on Tuesday morning. They responded shortly after opening time, which was good. It turns out the only good thing. I explained my situation, and they said that they were busy on Tuesday but would call me on Wednesday to schedule some time. Overall friendly.
They explained how they work with an outside firm that identifies leaks using some sort of infrared system, and that if they had to break into a wall that the damage is minimal because they know how to find the leak.
They mentioned that a visit would cost over $120, and I told them that was absolutely fine (I rent the unit so I have to get it fixed).
No word from them on Wednesday. I call them on Thursday and they had no idea who I was. I managed to jog someone's memory, and then she said that she remembered me and my situation. She didn't know what was going on and had to call me back. By this point I knew I was not going to use their service.
She then calls me back and said that they were going to have to dig into the wall and that they only do certain work and not other types of work and that I'd need someone of fix the walls. She offered a lame excuse to cover why they never called me back. I asked why she didn't mention this infrared company again. Then she just started babbling and I ended the call because they had already wasted two full days of my time.
I found a new plumber and they were there in two hours. They also didn't charge for the visit.
