Isaac came and fixed the problem quickly and at a good price. Great guy and very knowledgeable.

Five stars! Met Isaac Sr. today when looking for a local alternative to our usual plumbing company who couldn't get to us till tomorrow. Isaac gave me a 2 hour window but was polite to text 45 mins. into that time frame to apologize that a job was slowing down the time estimate so I would be forewarned. Very considerate. When he arrived (not too far off the original time frame) he was personable, friendly and professional. It turned out we need to buy a new kitchen faucet fixture but rather than just disappear and charge us the minimum, he got everything ready so my husband could purchase and install a new faucet simply. Then he charged less than half of the minimum he had quoted! I now have Isaac & Sons as my #1 Plumbing resource in my home maintenance index!!

After another company came out and said they wouldn't work on my water heater, I called Isaac & sons, should have been my first call!
He was super professional, on time, and I didn't pay a penny over the quote, which he gave me over the phone.
I would use this company again anytime.

Had an emergency water leak, called Isaac on a Sunday afternoon and he was able to come and fix my issue promptly. Highly recommend you call them for plumbing needs.

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.
