Recommended Customer Reviews

Keithley Plumbing is great! I have had two urgent plumbing situations and they have been able to get my issues fixed very quickly! they are honest and reasonable I highly recommend them!! family owned and operated

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.

Keithley gets a split rating. The 4-or 5 star part: I've always been happy with their work (repairs on old houses; never had them work on a remodel or new construction so I have no experience with them on that side). They were knowledgeable and able to fix vintage fixtures that others wouldn't touch. Their rates were no more / less than anyone else.
The 1 or 2 star part: I recently had terrible experiences with responsiveness. I called to schedule a service call, and the very pleasant person (no snark here; she was very nice) said she'd call back after checking with someone. No call back. 2 days later, I called again and confirmed an appointment. The scheduled time slot and the entire day day came and went, and...BUPKIS. No plumber, no call to reschedule, nothing.
I guess they have plenty of business and don't need mine. Sigh...I really liked these guys and their work. Time to go plumber shopping.

Did not do quality work whatsoever and I ended up having to hire someone else to fix their mistake. They would not come back to fix it and ended up hanging up on me.

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.

Keithley Plumbing is the absolute best. Had a leak in the walls. Brian & Jensen came out, looked things over, and got right down to work. Had the whole thing diagnosed, fixed, and back up and running in just hours. This was a rather complicated job with a lot of very intricate cuts and repairs in a craftsman home. Keithley nailed it. Polite, smart, diligent, clean, super positive attitude! Would give them a 10!

This company is an absolute nightmare, please avoid it like the plague, OVERCHARGED , LIED to
They're accustomed to overcharging unsuspecting homeowners , its their bread & butter.
Almost $300.00 for under one hour , flapper & fill valve , sink stopper . The wife /secretary estimated it to me by phone , it would be around $100 . The plumber should have told me the jobs estimate and I would have declined, instead an outrageous overcharge bill comes in the mail. I offered to pay $200 for the 45 minute service.
The wife is irate & rude and they sent bill to collections, now demanding $400.
I wish I had referred to YELP, as there's a long ugly history of overcharging, and bad service.

I just wanted to give the two Keithley plumbers, Brian and Jensen, a HUGE shout-out ""attaboy""!
These young men were fantastic. They were on time, friendly, listened, PROFESSIONAL, capable, fast, and flexible - when I asked them if they were vaccinated they answered (yes) with no attitude or defensiveness, and they went ahead and wore the additional face mask we asked them to wear in addition to the cloth neck masks they already had on. Seriously, these guys are representing Keithley in the best way.
I received the Keithley Plumbing name as a word-of-mouth reference from my neighbor, and I will now also refer anyone who asks me to them too.
Thanks again!

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.
