This review is long overdue. We had an issue with water pressure and drains in my aunts home in the Sunset district. Also, every time the rains came, the light well areas would back-up and required buckets to remove the standing water. I contacted Robert/Friendly Plumber in the end of July, 2010 based on the great reviews I'd read on YELP (I help my aunt with her home and actually don't live in SFO, so I was at a disadvantage on who to call). Robert was very articulate in providing his expertise and provided us with a couple of options. Further, he recommended that we call the water company for the water pressure issue and we found that the main line to the home was cracked, thus no pressure. At the onset, the water company was not convinced but sure enough, it was exactly as Robert had said (frankly, the city water inspector was quite surprised, he said most of the time the plumber is wrong). So, right after speaking with the water inspector, we hired Robert to replace all the old drain pipes and opted for the permanent fix or option 2 for the light wells. Robert also coordinated a roofer to repair/patch the roof in the areas that they installed allowing for proper drainage through the roof in the light wells. We opted for permits just in case, the city inspector stated that we definitely shouldn't have any issues in the future with leaking through the roof/light well areas, etc. and approved all the plumbing work. Robert's employees were also extremely respectful, dependable, knowledgeable, etc. Recently we had a small issue arise and called Robert, needless to say he attended to the issue the next morning at no charge. Oh, yes we do have awesome water pressure. I wouldn't hesitate to recommend or call on Robert again, his knowledge and professionalism definitely shows.
