Kapnag for some reason was recommended by Sloan Flushmate so I used them and assumed they would do a good job. What I got instead was bad advice, a bill that was reasonable I guess, and a quote that seemed high. The problem with all this is that the plumber didn’t fix the problem but said that it could not be fixed and the whole unit had to be replaced. The second plumber(known and trusted professional that we should have just waited for in the first place) fixed the problem in a matter of minutes and said he thought the Kapnag guy, Calvin, was trying to rip us off because the problem wasn’t that difficult yet he was telling us it was impossible to fix and would be $ 800 to come back on top of the $ 240 for coming, snaking, and ultimately not making anything better. Now, they’re not all bad. They offered to give us a break and not charge their overtime fee for working after 4pm and fit us in last minute, which I appreciated but with bad service it ultimately was a bad decision. Calvin was also a nice guy but in the end, did that really matter? Not much. Brett the owner, I believe, whom I called to discuss the issue became a little hostile when I said I thought Calvin didn’t do a good job by recommending that we replace the toilet because it would be impossible to fix. They must not be all bad and their rates are better than some but as for my experience I have to give them 2 stars, this despite being rather angry with this whole situation — if on feeling alone about the whole thing I would give them 1 star.
