Isaac & Sons Plumbing Glendora

Issac is a true professional. Excellent customer service and the product is top notch. He's a licensed plumber, which makes a difference in the knowledge he has when doing a job.

Mark came out this morning to check out the gas I smelled in the laundry room. I appreciate that he was wearing a mask and had a very nice demeanor from the start. And even though he couldn't smell it, he looked carefully for the leak (my nose is extra sensitive). He found the problem in the line to hook up the dryer to the gas, fixed it, and was on his way, after also tightening the hoses to the washer. I really appreciated the professionalism and manners. I would definitely call again with a plumbing problem. (I also liked that he called when he was on his way so I had time to put away the .)

Once again Isaac and his son have rescued us. In the past he had put a new shower in our downstairs bathroom. It is all working perfectly and is beautiful. Last week we found out from another plumber that we had 3 cracks in our main pipe going to the street. He suggested liner in pipe but his quote was off the charts! I hadn't called Isaac because we live in Huntington Beach and I knew it was so far for him. After that first quote, I called Isaac. He came down the next day and quoted $3,000 LESS than first plumber. His crew did the whole job of putting that fiberglass liner in the sewer pipe the day after he assessed. All was done 2 days after our initial problem. Thanks Isaac!! You and your son are the best!

As a small business owner myself I appreciated the personal service from Isaac. I used Isaac once before on a smaller job in my master bath which was resolved, so with that when my 75 gallon water heater sprang a leak on a Sunday I text Isaac to give me a call the following day on Monday not wanting to bother him on a weekend, well he immediately called me to assess the problem. He showed up first thing in the morning with his son and replaced the water heater at a very reasonable price. As I mentioned Isaac had his son with him who is learning the trade, this young man has a very bright future, very respectful to his father,asking questions and the drive to learn soon he will be a success. Every homeowner wants that go to tradesmen, Isaac and sons is my plumber.

This post is long overdue for sure. My grandmothers house in Ontario was having major plumbing issues. The main line was clogged and the pipe was broken in a few spots and needed to be dug out, repaired and patched and upgraded a bit.

I'm not a plumber and could not help my grandmother. What I was able to do is help her to not get ripped off and make sure she was taken care of. I reached out to a few friends and both gave me Isaacs number. He showed up within a day or so and was able to figure out what was going on. Not only did he show up earlier than the time he said he'd be there, but he had his shirt tucked in looked professional.

He didn't have the lowest price, but he also didn't try to upgrade us and sell us on things we did not need. He did exactly what he said he was gonna do, he had all the tools on him to get the job done. It was a 2 day project.

We were really impressed with his experience, integrity and his professionalism. Isaac is very likable and was friendly with grandma and took care of her. I didn't have to worry. Later on she hired him for a few smaller projects .


I would hire this company again and or refer them to anyone who is looking for someone who knows what they're doing.

Happy Customer Sousa Family

I scheduled w this company a week in advance. Got a quote over the phone. They arrived for their appt early which was great. The team was professional, fast and efficient. They did a great job and cleaned up their mess. They educated me on the problems I had and how it was fixed. If you need a plumber that alone sucks but these guys did a great job and I'm definitely satisfied! That's hard to get w tradesmen.

A bit late in writing this review but had to do it! Had a Main leak in my drive way and had to emergently look for a plumber, this happened a few months back during the crazy rain season. After getting a few estimates Isaac came by and patiently explained the problem and explained in detail how he could fix the leak by rerouting my main and not having to break all my cement in the process! Saved me a ton of money and put me at ease due to his patience and explanation of the process.. highly recommend, it's so difficult to find good people that are reliable and honest. Work was done well and completed on time! Will most definitely use again if I ever need plumbing services!

We have used Isaac twice now for plumbing leaks in our upstairs bathrooms. This time we told him it was time to totally remodel this 34 year old bathroom and fix the hokey plumbing the builder performed. Once the subfloor and drywall had been exposed, it was sad to see what shoddy work looked like. Isaac and his guys went to work and made it right. The subs he has work for him are excellent in every regard. The bottom line we have a beautiful new bathroom thanks to his attention to detail and demanding excellence from his subs. I can't say enough about Isaac and his work ethic. We highly recommend Isaac. Not only is he honest and trustworthy, he is quite personable and fun to have in our home.
