I think it is rather rude and a bit dishonest for people to not divulge their total fees upfront, an of course we should know to ask. But the normal person wouldn't know the questions to ask until they are burnt once like this, and then there still could be costs for walking up stairs or charge another service call if they need to go somewhere to use the bathroom and come back. THAT ISN'T A QUESTION I WOULD THINK TO ASK.
“My kitchen sink was clogging up, so I made an appointment with Mike Counsil plumbing. Yobani and another technician came to put an auger/snake through the wall, replaced my sink pipes and also fixed a leaky shower in the master bathroom. Yobani and his team were all very professional, knowledgeable and CLEAN!! They all wore booties, brought in a carpet to lay on my kitchen floor so as not to get debris everywhere. They weren’t able to fix the kitchen sink because it was determined to be a main line issue down in the garage (not my personal condo unit) that was causing the back-flow. So they did not charge me for the snake/auger services as it did not resolve the problem. They are a bit pricier, but I could see where my extra dollars were going for their service.”
Sometimes a faucet leak can be stopped by replacing the rubber washer at the end of a faucet stem or cartridge. This is a more common repair on older fixtures when things were built to last and designed to be able to be maintained. Other times the whole stem or cartridge needs replacement or the bibb seat deeper back into the fixture needs replacement. That leads to matching up the right components and often times making a trip to the hardware store or plumbing supply house necessary due to the many varieties, makes and models of faucets. My advice is to make sure your Plumber has faucet repair kit on their truck before having them come out to assess the issue.
