Recommended Customer Reviews

Issac and Sons are extremely professional. Our business had a problem with our toilets. First Plumber I called said he might be able to come in a couple of hours. Issac and Sons came within 20 minutes. They were prompt, pleasant and professional. Issac and Sons are now my plumbers for my business and for home.

Isaac and Sons response to my phone call was literally impressive. He showed up on time to our appointment and was thorough when I showed him our problem. The quote he gave was fair and he was willing to start immediately! Very impressed with his service and his professionalism. I highly recommend his plumbing service!

I just had Isaac come over with Mathew and they were awesome. Not only did Isaac answer my call as I had a leak in my guest bath sink, he was able to come over same day and within a couple of hours of my call. I was really worried as I have pex and bead board on the walls. I thought he was going to have to open my wall, but after looking at the problem more closely, he told me all I need was a new faucet. That's it! What I thought was going to be a monumental problem turned out to be something very simple. Isaac was so professional and not only that he didn't even charge me for the visit! Thank you so much Isaac and Mathew. I really appreciate your professionalism!

This review is being written for my parents.
Over the last few months they have had a few plumbing issues and having had bad experiences in the past with plumbers, either not doing a good job or charging an arm and a leg, we have tried to remedy the problems on our own. I was able to fix a few of their issues, but after a certain point youtube videos can only take you so far. I finally convinced my dad to get a plumber and after looking on yelp decided on Isaac and Sons because of all of the 5 star reviews.
Let me tell you, it was, and continues to be a great experience. Issac has serviced my parents home on two separate occasions, has done an amazing job with reasonable prices, is always prompt (usually next day service), and will explain any questions that you have. Isaac has fixed our bathroom sink, installed a new garbage disposal, and replaced an old hot water valve.
To truly state how impressive Isaac has been, only look to my mother, who is very cautious to people that come to work on our home, and even she has taken a liking to him. My dad says he is never going to go to another plumber as long as Isaac is around.

Issac came to my home and evaluated my problem at no cost! I can't say enough positive things about his helpful attitude. He is now my forever plumber and I can honestly recommend him to all! Julianne in San Dimas

If you need a plumber look no further! Isaac repiped our house in pex/copper and replaced water heater. They did very clean work it only took him 2 days. His estimate was beyond fair and stuck to his price even thought materials were more than expected. He definitely went above and beyond for us. Above all he was honest and straight forward about everything didn't try to take advantage of us!

Plumbing repairs are one of those unexpected, stressful, issues that sometimes you don't know who to trust. and more often get taken advantage of. Our most recent experience has turned that perception around for us.
Isaac is a great, experienced, hard working guy! he is honest and trustworthy. and isn't interested in charging the most expensive option. but will work with you on your budget needs. He is very fair and is more interested in gaining your buisness forever than gouging you on one visit. it is comforting to know when I'm in need of a plumber I only have to call one guy and be confident in a fair , honest price and a solid quality of work!

I called Isaac a few weeks ago for some help with a leak in a water pipe. I was on a tight time line and I needed a plumber like NOW! Isaac rearranged his schedule on very short notice to meet me for a quote which was awesome! Isaac showed up right on time and his quote was by far better than any of these big box companies. You can tell Isaac is a good guy, and a straight shooter. Isaac got the job done right and I'm very appreciative! Thank you Isaac! I highly recommend Isaac & Son! A good plumber like Isaac is HARD to find!

Well, where do I start. Being a Firefighter we tend to do things on our own a lot because it's hard to find good quality work and work ethic. When confirmed by Mike Diamond I needed a sewer line access installed to clear out some roots they were charging me between $2300-$4600. Obviously I knew that was a bit to much. So of course I did what anyone else what do and I yelped around my area. When I came across Isaac and sons after reading the review I put him down as the 3rd quote for the job. After calling all 3 companies he was the most up front individual. Then when he quoted me $1000 to do not only what Mike Diamond was going to do but he was going to do it the next day. He got my buisness and future jobs also. He was professional and was a people person which now days a lot of companies lack. I recommend Isaac and sons not only to you all on Yelp but to ALL my fellow colleagues in my profession. Thanks Isaac and sons!!!

Isaac & Sons is a good company owned and operated by a decent and honest man. I am generally pretty wary of service taking advantage of me because I'm both a widow and not knowledgeable about these types of things. However,my experience with this company was very positive and completely different from what I have experienced in the past.
Isaac provided outstanding service on a big job that involved multiple runs of his camera to the sewer, hydrojetting roots, lots of broken pipe and ultimately installing a new liner from the front of my house to the main sewer line. He kept me informed about what was going on throughout every step of this job. I don't think he could have been more thorough. I really appreciated the time and effort that was put into this project. I highly recommend this professional and courteous company who put the customer first. I am so thankful for Isaac and the rest of his crew!!
