    Kathy's employees were supposed to move the old pipe, which they apparently did not.

    They had done a plumbing job on one of my properties. They were supposed to remove the old copper pipe and install new PEC. I went up to look at the work because I had to run something up above the ceiling. Very sad to see if they did not remove the copper pipe like they were supposed to. They charged me to remove all of the old plumbing pipes and install PEX pipe. When I look up there, they left the old pipe without removing it. They also charged me to install new toilet flappers, which they did not do in any of the toilets. I believe the son was doing the job with a worker. Disappointment, considering this is the son of the owner.

    Pink slip from city for toxic gas venting too close to bedroom window! Killed the plant it was directed at!

    Do not hire Keithley Plumbing! Not any more. We had multiple failures in inspections--see that the city lists them as 18 because we couldn't pass for a number of reasons one after the other! Horrible cheap work! I also had 2 failures with the Gas Company. Once Keithley had left a gas line wide open and could have blown up the house! There were electrical workers there, no less! The gas man scrambled to turn it off, red tagged me and I had to start all over. That was the second Gas Company refusal to start service due to safety concerns. They are very dishonest with their billing and quality of work. PLEASE REVIEW YOUR CONTRACT CAREFULLY and make sure every single provision is delineated to the letter. They are quick to renigg on work that was verbally discussed in DETAIL, but then intentionally vague in the contract. They used plastic pex pipes instead of the copper we agreed upon. Pex copper means plastic pipes, by the way, and they use the excuse that Pasadena water additives cause pin hole leaks... and we are cooking and showering with this water? Give me a break! I have had copper at our old house for 18 years and no problems! They did NOT give us new drains, as stated in the contract but pieced in just enough to make things work. See the pictures marked by another plumber and ones taken by us. Those marked in yellow are old drains. We asked them to make it right, but they would not. We ended up having to go to court and they lied about the whole thing, saying that they define new drains as the least amount they can get away with... All are to the closest bend and tied into 70 year old drains in 2 out of the 3 instances. I was charged $550 per each new drain for 6"- 8" of pipe. One drain did go all the way to the main, also $550? Who would know, unless you or another plumber go into your crawl space. Also, RATS CAN AND DO CHEW THROUGH PEX. Just google it. I have asked two plumbers since and pex is crap that's only recently become legal because of the copper theft problem. They also pretty much say Keithley's work is only passible (after 16 tries.) The proof is in the pics of their work, multiple failures from the city and texts from my new plumber. To top it all off, they were supposed to move a 300 lb cast iron tub, demo a wall and move it to another bathroom. I scrapped that project but they refused to give me any credit. That may be legal, but it's not ethical. So disappointed in putting so much trust in an old reputation.

    I have nothing but great things to say about QP Plumbing! Oscar is very responsive, professional,…read moreeasy to work with, and an overall stand up guy with a high level of integrity. Last year we had a water heater installed by QP Plumbing. There was one part of the installation that was overlooked and caused us some issues. When I told Oscar, he took complete accountability and offered to give us monetary compensation. I told him if he could just provide us with a credit on future service that would be great. Fast forward to present day, we had leak with one of our pipes. Oscar was able to come immediately to diagnose the issue and got his crew here the next day to get the issue resolved. Oscar did in fact give me the credit we had discussed over a year ago which I appreciated. I certainly plan to use QP Plumbing for any of my plumbing needs moving forward and I would highly recommend them.

    Your home's plumbing is an "out of sight, out of mind" thing. If you don't have to think about it,…read morethen it's doing its job correctly. My parents-in-law had a toilet that wasn't draining properly, a semi-emergency since it's the only toilet in their small condo. It was already late in the day, but I found QP Plumbing and messaged them and they were able to have a plumber out early the next morning. Leo was the plumber who visited and he did a lot of troubleshooting: first with a plunger, then an auger, then removing the toilet to inspect the trap and the drain pipe. In the end, we determined that the toilet should be replaced because of its age, and Leo took care of buying a new toilet, installing it, and hauling the old one away. He recommended a toilet that's elongated and slightly higher, which was a great option for our elderly parents with reduced mobility. Leo also replaced the wax ring and flange bolts and caulked the new toilet well. He took the time to do the job right, and the price was quite reasonable. And the new toilet is a huge improvement over the old one. Thanks QP for the quality work and for giving our parents one less thing to have to worry about!
