    Brandon Sellers 55L

    We cannot say enough good things about 55L Brandon Sellers with Mullin Plumbing and his assistant, Preston, that have been working with us through a 'perfect storm' of a disaster in our home that started with a slab leak just before Christmas and continued with finding multiple septic leaks in the slab that required extensive repair. Brandon has been knowledgeable, courteous, and very meticulous about daily keeping the workspace clean. He patiently took extra time to explain exactly what went wrong and how they were fixing it, which gave me total peace of mind. The respect, kindness and genuine empathy he has shown us during these last six weeks of repairs has made the 'nightmare' much more bearable as well as all the ways he worked with us to make it as cost effective as possible. We are so thankful for Mullin Plumbing, and although we hope to never have to call them again, we will trust them with any future HVAC and septic needs.

    Supposedly what they fixed for $8,500. Only photo they have shown

    Please don't use mullin plumbing. They may take advantage of the elderly. Go ahead and read all the terrible recent reviews of their horrible services Edit 11/7/23. Typical mullin response. You know exactly who I am. The one you called an idiot yesterday 11/6/23 and hung up on. Sounds like the same incompetence that spews from every leaky faucet they've touched. This company bullies it's customers and calls them names. Charged an elderly woman $8,500 and left an open loop system running for weeks. Attached is the only photo they've provided for their $8,500 bill. Who knows what that is or when/where it's from.

    Pressure relief valve

    We called our rural water district out several times due to low water pressure. We called Mullins to review water flow on rural side which was operating normally and they discovered it was a water pressure relief valve. The work began because it was not found in the water service meter. Hunter and Dalton began the task to find it. They kept us informed along the way and talked with us about every step of discovery. We would highly recommend Hunter, Dalton, and Mullin Plumbing for your plumbing needs. They found it and we now have great water pressure! Thank you again Hinter and Dalton! Ron and Theresa Scott wagoner, OK

    Quote over $14,000 to trade out to faucets and replace 2 water heaters, with us providing all 4 items.

    They were able to get to me right away and I wasn't inconvenienced for long. The price was fair and the was outstanding.

    I had to call out Mullin Plumbing several days ago because the toilet in one of the bathrooms wasn't working properly anymore.

The technician was professional and courteous. The issue was not the work itself, but the lack of transparency and the lack of response afterward. I asked for a breakdown of parts and labor and whether there were any alternative options or pricing tiers. None were available, and no one could explain the pricing beyond "that's just what it is." The $3,100 charge for a water heater felt high, especially given that I was told there was only one option and no flexibility. I later received a call from the plumbing manager explaining that the higher cost was due to an extended warranty and the use of brass parts, which I appreciated. However, I still never received a clear breakdown or the ability to compare options. I followed up multiple times with management and ownership to share feedback and ask for clarification and never received a response. That lack of engagement is what ultimately led me to post this review. I'm sharing this so others know what to expect: the work itself may be fine, but if you have questions about cost, want to understand what you're paying for, or hope for engagement when concerns are raised, you may not get it. I'll be going elsewhere for plumbing work in the future. The photo attached is of a part that was left in my driveway -- not a major issue by itself, but it added to the overall impression of a rushed and impersonal experience.

Didn't have to, he wasn't late. They said he'd be there 8-10a. Said "GPS says I'll be there for 8:17a". Good start in my book. Tom toured the 2 floor home. It has brand new oil furnace, forced air in an "octopus" vent system, so we expected to be paying their high range of $500ish. That's half what others have quoted us though. We opted for sanitizer as well (with Moms allergies we decided to since it was being done). That was $200-250. Has a nice lemony scent for a little while, minor. Lasts less than an hour. Tom finished his work 1-2p and while he did turn on furnace to see if debris came out anywhere, nothing of note did at that time. It happened later on that soot and debris came out of all the vents. We contacted Tommy and here's why he gets the five stars he deserves. He immediately apologized profusely. He said while he's not sure why it was doing that now and didn't before, he will come right back out as soon as possible. He couldn't return until Saturday, he was on jobs when we told him (the day after, so one day was in between). And return he did. He texted his arrival time and apologized again when he showed up. He's genuine in demeanor, I don't get that vibe that he knew something was off. He was sincerely sorry and felt bad the job wasn't satisfied, worse felt bad my Mom's allergies were triggered. He spent several more hours this morning cleaning up anything he saw, and of course troubleshot where he thought the catches of debris may have happened. Very "extra" thorough, as best he could. Tommy stood by his work. His very words were he warranties his work, an actual warranty or moral one I don't think that mattered to him. He and I agree, the home's octopus vents and setup possibly made this job more difficult than a usual one. To me, it's how you handle those ones that go haywire that highlight what kind of a person and company you are. These guys passed with flying colors.
