Recommended Customer Reviews

Really impressive! Got a list of many plumbers from George's Kitchen & Bath as we are new to the area. Half didn't return my call for a quote and while Keithley came in less than the others, it was the ease of getting the info and then scheduling that kicked things off on a good foot (props to Phyllis and Stephanie for excellent customer service).
Brian and his partner showed up promptly, were so personable, respectful and knowledgeable. Some of what we asked for was a little out of their scope yet they totally nailed it. The job was executed flawlessly and while we were thrilled with the end result, there's 1 little thing that made them stand out from anyone else- we made sure their work area was clean and tidy when they arrived and I swear it was cleaner when they left.
At this stage in the game I wouldn't even consider using another plumber- if my 1st experience is standard operating procedure for Keithley, I can get used to this!

We are two long-time teachers. Keithley took advantage of us during COVID, installed a hot-water heater that we did not order and that failed to pass city's building/safety code, so Keithley had to redo the work. He also repeatedly told us things that were false
We hired Keithley because our hot water heater went out suddenly and he was the only plumber who was free. Our big mistake was accepting his request no written contract. He also wanted no permit/inspection, but we insisted on a permit. We gave Keithley a list of 5 requirements for the new hot-water heater. Instead of telling us that Keithley did not have the water heater that we wanted, Keithley installed a cheap, 20-gallon too large, not-energy-efficient HWH that we did not order, and told us that the heater we wanted ""was not available,"" but he was installing something close to what we wanted. His claim is false. We also asked for a manual for the heater. He said there was no manual. This second claim is false We could not see exactly what he installed until after he left, because of COVID social distancing.
As soon as Keithley left, we saw that he had installed a cheaper, much larger, not energy efficient heater, not what we requested. We immediately called the manufacturer listed on the heater. We asked the manufacturer if he made the water heater that fit our 5 requests, given to Keithley. He said they did make exactly what we wanted, and that every installer has a manual to give us. We also checked Lowe's and home Depot. Both had, in stock, the exact heater that we requested from Keithley.
Next we called Keithley to ask why he installed a cheap, too large, not energy efficient heater that we had not ordered. He and the entire office repeated his false claim; ""what you wanted was not available."" When we told Keithley that we were teachers, that we had checked, that the heater (we ordered) was available from the manufacturer, at Lowe's, and at Home Depot---suddenly he changed his story. For the first time, he said what we wanted was not available from their distributor. If Keithley had told us this, up front, we would never have hired him. We then said Keithley had to install the correct heater, even if we had to pay more for it.
Keithley said that because there was no written contract, he did not have to install what we wanted. Having no choice except to take the cheap heater we never wanted, we agreed to pay Keithley the remaining 1/3 of the bill, but only (1) if his work passed city-permit inspection and (2) if he gave us a contract indicating all workers and distributors had been paid. Keithley then told us a third false statement,. Keithley said we had to pay them, whether or not they guaranteed payment of subs/lien release. State law says no such thing, and we told Keithley that. The inspector found a serious code violation that would have leaked water all over the floor; the inspector forced Keithley to correct his poor work.
When Keithley could see that we were not going to pay the remaining 1/3 for the heater (that we never ordered) unless we had a contract showing payment of subs/lien release, finally, after 5 months, Keithley gave us the contract showing payment of subs/lien release, and we paid him. The moral: (1) Get a written contract. (2) Don't trust anything Keithley tells you. (He also told us the heater did not need to be flushed, which is false.) (3) Get a permit and inspector; luckily we did this. (4) Warn your friends about Keithley. We have lost $1500 for a cheap, worthless heater that we never ordered----all because during early COVID days, we trusted what Keithley said. Don't make our mistake.

A friend referred us to Dan around 15 years ago, and Keithley Plumbing has been handling all of our plumbing needs ever since. We have always been very pleased with their services.

Knowing how busy you are, we booked our appointment online over the weekend. Phyllis emailed us and scheduled an appointment for Dan to come out a few days later. Thank you Dan for helping us out with our plumbing issues last week. As always Keithley Plumbing has always been our best go to for plumbing help.
You are always on the spot with finding and fixing the issue. And your price is beyond comparable, much appreciated. As local Pasadena residents, we are happy to support and trust a locally owned businesses like yours.
Thank you again,
Thuy and Josh

Keithley is the best! They've been my plumber for several years and they always get the job done right the first time, at a very reasonable price. No job has been too big or small for them. They show up when they say and don't try to upsell you a bunch of work you don't need like the big radio-ad places do. They are a family business and know who they are sending to your house. Always nice, professional, and honest. Support local business and give them a call. They'll get it done.

Excellent customer service with easy scheduling and professional communication. We own a large home in Arcadia and have used Keithley Plumbing on several occasions for jobs big and small. They are punctual, knowledgeable and always thorough. They get the job done to perfection in a timely manner, always cost efficient and mindful. This company has been a lifesaver for us and we will continue to use their services for as long as we own this home. Shoutout to Dan who with his vast experience shows up night and day when we need him, always professional, spot on with the problem and with a smile. Thank you Keithley Plumbing for providing such high level service to our area!

This has been our families plumber for as long as I can remember. They service all our family members homes. Dan & Brian are amazing. The ladies in the office are always great with scheduling and any bill related questions we may have. I have had my water heater replaced along with several other services. I am always so pleased by their work and their perfect price point. If you need reliable, professional & affordable plumbing you can't go wrong with this company

We have been calling Keithley Plumbing for 30+ years. We could not be happier with their service and their products. I would recommend Dan and his family to anyone and everyone.

I called on Keithley plumbing to do some minor, some major work. After reviewing my situation Dan, the plumber, made a careful observation and saved me from an expensive mistake. Not everyone is so helpful and I really appreciate Dan's help. Keithley will definitely be my go to Plumber!

I have an older townhome in which original plumbing was done with little care, and the owner before me constantly overestimated his DIY skills. Dan Keithley and his technicians have kept everything working. Most recently, I discovered a leak in the wall behind my sink. Dan and Phyllis sent two of the younger plumbers. They were conscientious, pleasant, and professional, and they did an excellent job with the unusual, annoying, poorly-assembled plumbing. The job required creative problem-solving skills, in addition to knowledge and patience, and I was grateful for the intelligence and care with which they handled it. They tracked down and repaired two distinct cracks in the pipe in my wall and replaced several defective sections, all while wearing masks.
