Micro plumbing. We just had a problem with our sewer line. Another company gave us a very expensive quote and said we have to replace the whole line from the house to the street. Micro gave us a lower bid. When they dug up say told us the other company was ripping us off. That the whole line did not need to be replaced, that only one area needed to be replaced and since we put a down payment down half of it would be coming back to us from Micro. We have used them for years and they have always shown us that they are a honest company.
