Recommended Customer Reviews

My water heater broke at my non-English speaking parents house in Pomona. After a few estimates, Don gave us the best price and best work. He came out the next day and had it done instantly. He was professional, knowledgeable. My parents loved his excellent work!

Once again, Don came to our rescue. A few years ago, he serviced our tankless water heater and provided advice to help keep it going until we saved up funds to replace it. We finally decided it was time to replace our tankless water heater. The online estimating and scheduling processes were super easy to navigate, and the installation was flawless.

This company is very professional and reliable. They work perfectly and we highly recommend this company Stanley Plumbing

Don is very knowledgeable and is a pleasure to work with. He replaced my tankless heater and I am happy with the results to date. If you are in the market for a new or replacement tankless water heater, I would recommend reaching out to Stanley Plumbing for an assessment and quote.

Don installed a tankless water heater for me, Did a super clean job, the endless hot water is awesome. I checked pricing with a few other plumbers and Stanley Plumbing was right in line, however I believe I was getting more bang for my buck. I also had Don install a water softener that continues to work great.

If you do not mind chasing your contractor for weeks, then Don is suggested. He is very knowledgeable and has resolved issues. Good luck !

Don and team installed a tankless water heater for me over a year ago. They did a great job! The installation was quick , clean and as they said it would be. I would definitely use them again.

Have yet to get a return call after leaving three messages during the past week.
Might change the rating if they every do call back.
Honestly, they're a zero for me right now and I'm looking for someone else.
p.s. I rarely do reviews but these folks were recommended by the manufacturer.

Don installed a Noritz tankless water heater and Falsken Water softner over a month ago and I am very pleased with his professionalism and workmanship, simply top notch.
He removed our old unit that was installed improperly years ago, made the necessary corrections to the lines and completed his work within the time he estimated.
I would highly recommend Stanley Plumbing for all plumbing repairs or upgrades.

I recently had my Noritz tankless water heater repaired & updated. I also at the same time had a new gas line installed by Don with Stanley Plumbing. Don did an outstanding job on both projects! His work was extremely clean & he finished in the amount of time he said it would take him. Very professional as well as knowledgeable. I would highly recommend Stanley Plumbing if you are in need of any type of plumbing needs.
Very impressed!!
Thank You Don for a job well done!
