I could have died from carbon monoxide poisoning. I hired Frank, he never told me his last name, to…read morerepair two bathroom drain pipes that shared one wall in early March 2026. I asked him if I would need a work permit pulled for these repairs and he said "no". I thought F.S. Plumbing was a licensed plumbing company. I later found out it is not a licensed plumbing company. I also found out from both St. Louis County and St. Charles County that a permit would have been required for these four repairs. When Frank came out to do the work, he tore out a part of the wall in my bathroom, he said the only way to repair both drain pipes was to cut a hole into the metal vent that was inside the wall. I asked him if it could be easily repaired and he said that it would be an easy fix and that I could fix it myself with a piece of metal and a few screws. He told me he thought it was a cold air return. When I told him my cold air return was in the hallway, he didn't respond. I then told him I thought that was the vent coming off my furnace and asked if he wanted to go to the basement to look. He had been in my basement earlier to look at my outdoor faucet pipes since he was going to repair them as well. He declined going to look in the basement to see what the vent was and he proceeded cutting into the vent. He cut a large hole in the vent and the way that it was cut I saw no way to repair it since the one drain pipe was running right through it. I decided to Google "can you cut a hole in a furnace vent?" I got the quick response of "absolutely not". I called my local fire marshal and he agreed that it should have never been cut due to it being the furnace and water heater flue vent for carbon monoxide release. I called a retired HVAC friend and he said Frank, a plumber, should have known that you can't cut open a furnace flue vent. He told me not to pay Frank until I found out how much it would cost to replace the flue section. After I researched and found out this information, Frank asked to be paid. I told him I couldn't pay him that day until I found out exactly what it was going to cost to replace the flue vent. He said he wouldn't leave my house until I paid in full. I felt threatened and intimidated so I wrote him a check for the full amount of $1495. Frank left the house and, I found out later, he immediately drove to my personal bank (of the check) and cashed the check that same day. Also, when Frank left my house, he didn't tell me to not use my heat or hot water, or to turn them off in the basement. I could have died of carbon monoxide poisoning if I hadn't called my friend, later, who told me this fact. My friend told me how to shut off the gas furnace and water heater valves after Frank left to cash my check. I didn't have heat or hot water for over two weeks until the flue vent was ordered, delivered, and replaced. (The vent was a special order and came from out of State since it was a vent from the 1960's and no other manufactured flue vents would fit properly or safely). Frank refused to pay for the repair which turned out to be a replacement of the section of flue vent between the two bathrooms. I got 4 bids for him so he would see I was trying to get him the lowest price for the flue replacement. The HVAC bids ranged from $1500 - $2500. Frank came over to my house a few days after his initial work and said he was going to "fix" my flue vent. He was holding a tube of caulk and a piece of metal. I told him again that the flue section had to be completely replaced. He didn't believe that the flue had to be replaced even though a fire marshal and six HVAC guys said the situation was very dangerous and the vent section had to be replaced. I spoke to Frank, off and on, for three weeks giving him ample time to do the right thing and pay for the flue replacement. He refused, and the last time I texted him he texted me "God is watching". I had the flue vent replaced and I paid for it. I, also, had to have another plumber redo the drain pipe repairs that Frank charged me $895, I had to pay an additional $1000 for the drain pipes to be moved to the correct position, away from the vent. I had to have the wall repaired with new dry wall and tape since the HVAC man had to tear the wall out to get to the entire flue vent. I contacted YELP in late March since Frank has the red YELP GUARANTEE but they have not responded to my filed claim. I have contacted the Missouri Attorney General Consumer Complaint department and they have opened complaints against YELP and F.S. Plumbing and are currently investigating the claims.

May 2025 plumber came out after line they fixed broke for the 3rd time on outside faucet…read more Incompetent for the start since house is only 20 years old at time this started so I don't buy into outside wall was issue now. Only a few feet are on outside wall. He suggested to have line in poly tube over cooper and we agreed. The company was to have someone come out to do so. After months of no call I called beginning of March 2026 asking what happened, we need it fixed and wanted someone to do so. Schedule only allowed for two weeks out approximately. Scheduled and blocked day off. Now today plumber comes out and it's the original man who can't do any work due to injury. so he calls office and now they want to schedule it out again. Incompetence of this company is ridiculous. We had 3 other jobs we needed done too and they will not get the work. Time to find a reliable plumber.
