  I used the get a free quote service on Yelp to find a plumber that can swap out a Moen cartridge in my shower and got a response from Oh No Plumbing. I let them know that I had a replacement cartridge already from Moen and that the set screw on the handle was stripped. They said they could have someone swap out the shower cartridge for $166 so I got scheduled. Day of the appointment they don't show up until after 3pm for a 10am to 2pm arrival window. The plumber Chris goes to work and is unable to take the shower handle off to get to the cartridge because of the stripped screw which he should have already known about. I agree to let him cutoff the handle and install a new handle and trim kit. My wife had to run to Home Depot and pick up a new kit while he was cutting off the handle so he could install it. This ended up being a bad decision causing us to not have water for the whole house until the next day! He has a hard time getting the cartridge out even with the removal tool that was sent by Moen with the replacement cartridge and breaks off the cartridge inside of the removal tool. He ends up having to drill out the cartridge and what should have been a quick simple swap out is now taking about 2 hours. With the handle and cartridge removed he is having a hard time getting the new cartridge in and questions whether it is the correct one or not. Says that Moen has 6 different cartridges and this might not be the right one. No, this is a Moen Posi-Temp shower so it would be the Moen 1222/1222B cartridge which is what Moen had sent out and was same as what was already in there. After trying multiple times unsuccessfully to insert the new cartridge he says that we will need to have the valve replaced and it will cost $1,240! Well we are kinda of screwed at this point because the main water is off and can't be turned back on until the cartridge has been replaced so agree. But because they were late and took so long to get to this point they can no longer get the parts necessary to complete the job until the next morning meaning no water for us for the rest of the night. He says they will cut a whole in the closet to access the valve and then cover with a panel. He says they will put plastic down when he comes back and cover up vent so that dust doesn't go everywhere and will be here first thing in the morning after getting parts from the store they work with. He comes back in the morning and goes to work, doesn't use any plastic tarps like he said. He needs to borrow a pair of scissors to cut out the template for the new kit cause he didn't come prepared with all the tools he needs so I give him the pair of scissors we had in the kitchen. After he leaves I remembered I gave him the scissors and he didn't hand them back before he left. I messaged him after he left if he had them and he said no, that he thought he put them on the shelf on the closet. Checked all over and they are gone. Messaged him again if he was sure, he said he would check and didn't have them. My guess is he took them by mistake when he packed up and didn't want to drive all the way back here to return them. Now my wife is out of her $150 Cutco kitchen shears. The access panel that was supposed to cover the hole in the closet is a joke. You can see from the picture how poor of a job this was. I would definitely not recommend this company. They clearly are inexperienced and do not do quality work.

  Oh No came as a referral from my neighborhood social media group. They were able to get me scheduled quickly for maintenance on my AC and tankless water heater and pricing has been fair so far. I was initially impressed by Andrea, who reached out to schedule my service and followed up when she said she would. Don came out for my plumbing and was great. He is very knowledgable and was able to clearly articulate everything he recommended and next steps.

  I was scheduled for Chris come out and repair a leaking hose bib in my backyard. First and foremost, the office staff was very friendly and helpful and made scheduling this very simple. I received updates to when Chris was going to arrive and when he finally arrived. I really liked how Chris was so informative and detailed in his work. He took the time to explain to me what he was doing, which I really appreciated because I don't usually get that level of service nowadays. Im naturally curious about plumbing but too afraid to try any of it myself, so Chris giving me the time he did without seeming rushed to finish the job was refreshing. The pricing was very fair for the level of service provided and the work done, and this was overall a very pleasant experience. Kudos to management for keeping this level of service alive.
