Recommended Customer Reviews

We called quarter moon for a backed up toilet and shower for the home we purchased. The plumber said they pushed the blockage out to the main sewer but two weeks later: same issue. Used the toilet maybe half a dozen times. I called and the customer service manager said it wasn't covered in by their 90 day warranty because we elected not to pay another $300 up sell at the time of service for a camera run down the pipes. Also they came in at twice their estimated cost for the service in the first place. They won't be getting my business or my recommendation.

I get that late night call from son that he has no water. We find a broken pvc line going into house but we can't get the water off. While trying to fix we end up breaking the line that is threaded into the copper pipe going in the house. It is now 11pm and all the stores closed. We call quarter moon. They arrive within an hour and we get to meet a true professional. Adam looks at our mess and says the four kids can take a shower in 45 minutes and went to work. This guy has all the newest tools/gadgets/supplies on his truck. He was able to work around a stuck open City water line. Can't thank Adam and Quarter Moon enough. Also for a midnight plumbing job they were very fair. I will highly recommend their service. Still have not been meet Nigel yet but he sales a great service.

Quarter Moon Plumbing is who you need to choose for your next plumbing project or issue. After sending an online request for service early evening, within the hour, I received a call from Adam. He listened to my issue and provided honest feedback. Communication was excellent as he text me when he was arriving and the repair was done quickly AND at a cost that was within our budget!!! If possible, ask for Adam. He's a great man who is a professional with integrity and honesty. Don't bother price shopping....Quarter Moon Plumbing is a company that can be trusted .

I have used Quarter Moon at my home and my rental. I found their prices to be competitive and they show up when you need them. With a plumbing problem; that's important.

Had major root issues under my foundation. In the end of the job they charge me $550. Less than quoted price. Some patch work was not necessary. Thank God for honesty in these hard times . The report 18 pages long of what they did and warranty on the work . Employees very polite and professional!

3 hours of $125/hr labor before they ever turned a wrench!! Water heater went out so i called the folks i heard advertising on KTSA; Quarter Moon Plumbing. They came out and wrote it up as a "Tank Failure". Not a huge deal right?? After all, it's under warranty. You would think a plumbing company, who probably does this a lot more than me, would have a process for this... You would be wrong. Quarter Moon made me do all the leg work of calling the Water Heater folks and getting a replacement shipped to a local Ferguson's. After securing my own replacement, I gave this info to Quarter Moon so they could grab and install it. They still couldn't find it. After them failing to track down where the replacement heater was, I had to call Ferguson's to find out which location had my water heater and then let my tech know. On top of all that... They didn't have the water heater tag so they couldn't pick it up. So, they billed me for going to Ferguson's without the water heater tag, billed me for driving to my house and grabbing the tag, and then billed me for driving BACK to the Rim. Quarter Moon charged me for the 3 hours of them figuring out how to pick up a water heater!! I would think a plumbing company would have this process all figured out, but no. 3 hours of $125/hour labor before they ever turned a wrench. Once they switched it out... they left water in my drain pan and the floor around the water heater soaked. I will never use these folks again.

Update: The first couple of times I called Quarter Moon the service and experience was great. Fast forward to 2019 and my 5-Star review and a hearty recommendation is now practically 0 and a no-go to my family, friends, and associates. The past couple of services have been poor to infuriating. In my experience with this company, you get whoever they have available even if you requested and set up and appointment with a specific individual. The last plumber they sent out did an okay job but charged me for an hour of time before they arrived. I protested to them and the dispatcher but was told they could bill me for the drive (or time it takes) to get from the last job to my location. What!? I can't believe they are a USAA preferred vendor. What a rip! QMP = done!

Had Quarter Moon install 2 faucets in the bathroom and do the spring/ summer check on A/C- excellent job. Did a good job, cleaned up and we got service on the day we called! Kudos! Will. Use again!

I had a leak in our newly purchased home. Not one out of 3 techs sent by my home warranty could determine the location. Plumber said AC problem, AC tech said plumbing problem. I called Quarter Moon Plumber to bypass home warranty(worthless). James came to my home, with Ernest. They located and cleared out the AC condensation pipe. Explained everything to me. I was treated with respect and kindness. Being the lady of the house sometimes techs can be condescending and rude. These gentlemen were the utmost professionals. Will use them again.

Poor communication. We were booked for an estimate, left waiting all afternoon. When we called we were told we "fell through the cracks" and got rebooked for 2nd appointment the next day. That got rescheduled. When the guy finally came out he was not willing to provide a quote. We contacted Quarter Moon to let them know what happened and were passed off to a supervisor because they "didn't want the relationship to end this way." When that supervisor called back he provided an idea of repair costs. He then said that to get a written quote he would charge $105.00- something that had not been mentioned before. He actually said, "I can't send out employees to provide quotes- that's lost time and gas."
Yeah pretty safe to say these guys won't be chosen for our job. We will go with a company that shows up on time and delivers what they say they will- a free estimate on service cost.
