Recommended Customer Reviews

Aaron Petrossian of Complete Plumbing oversaw my condo renovation. His company was initially recommended to me by a close friend. Aaron was simply outstanding. There are so many good things to say about him.
A second-generation licensed contractor, Aaron has lots of knowledge and experience under his belt. He always offered a professional and balanced perspective about things and gave great advice that made decision-making easier for me.
Aaron is an excellent communicator: enthusiastic, personal, gracious, and easy to work with. Very patient, he was always ready to explain things to someone who had many questions, who didn't always understand things when told, and who always needed to know ""why.""
A great time manager, Aaron's intuitive understanding of the flow of the construction industry kept me and my project on schedule despite the vicissitudes of the pandemic. His network of subcontractors is excellent and top-notch. All of them rigorously observed the stringent regulations of my HOA. They were on schedule, clean and tidy, and were flexible and gracious about the inevitable issues that would come up. They did great work and won the respect of our homeowners. Aaron took the greatest attention to detail in his specialty, the plumbing, and did the most beautiful work and layout.
I am so happy with my remodel. For years I had a dream of upgrading my condo but didn't know if it would ever be realized. Thanks to Aaron I am now living in my dream home.

Aaron at Complete Plumbing did an excellent job replacing our water heater. He came to our home, discussed with us the issues we were having with our water heater, and presented two options. When we decided to replace the old unit, he shopped for one that would meet our needs and fit in the limited space we had. He returned the same day with the new unit and promptly installed it. He even presented us with an option to save $350 which we accepted. It was all done in one day, and the unit is functioning very well. Thanks, Aaron for a great job.

I needed a hot water heater installed ASAP. I called Aaron and he was able to come over the next day. He was able to take the necessary measurements, determine which fittings were needed, obtaining and installing a new hot water heater, and testing all the water lines in a very efficient manner.
I highly recommend their company.

I called Complete Plumbing after talking to manager at Ace hardware about a leak on my hot water copper pipe under the house and he gave me the phone number of a good plumber that was reasonable on their price of service. I called at 9 am and Aaron was at my house by 1 pm and we crawled under the house where I showed him where it was leaking. It was fixed by 2:30 pm. He was very competent and very fit which is important when you have get under the house and fix . That is hard work. I highly recommend this company.

Aaron and his dad did a few projects for me: my entire kitchen renovation, plus a few items in our bathroom, including:
- hot and cold water lines for kitchen sink + drain
- hot and cold water lines for washer and dryer + drain
- cold water line for refrigerator
- dishwasher installation
- garbage disposal installation
- water filter installation
- kitchen faucet installation
- recirculating water pump installation under the bathroom sink for getting instant water for our tankless water heater
- replacing the bathroom faucet and drain installation
- troubleshooting the bathroom faucet which had low flow.
Overall I'm very satisfied. Aaron is very detailed oriented, excellent at explaining things over, very timely and reliable, and executed the work quickly.
I would absolutely recommend Aaron for these projects!

I called up and left a message with Complete Plumbing for a quote to replace my water heater. Aaron called me back within 1 hour, we discussed my situation and he gave me a rough estimate (quite reasonable), based on the information I provided. We scheduled a time for Aaron to come by and inspect my failing water heater. Aaron dropped by, inspected and honored his original quote to replace my water heater. That same day Aaron was able to fit me in and replace my water heater (about 3-4 hours total which included a trip to Home Depot for a heater and other parts to bring it up to code). Aaron did a great job and is a nice guy. Responsive, conscientious, friendly, clean, knowledgably (explained things) and did a great job on the install. I would absolutely recommend his company and would feel comfortable having him go do work at my elderly mother's house.

This company is the real deal. VERY NICE and professional.
Came into my business and we got talking and asked if they would install a faucet in my restroom. They Aaron said we can do it for you. When I asked when they could do it he said right away. 20 minutes later I have a faucet that works great.
That you so much for the great work and be so friendly.
There are a lot of plumbing companies out there but not as good as these guys. Family run business. I like supporting small business.
You won't be disappointed with this company.

Aaron and his dad Raffi were absolute pleasure to deal with. They are responsive, knowledgeable, prompt and their work is really clean!
They were punctual, which is really important to me and gotten back within the time they said they will. While we invited them to fix an ice maker line that we found out was not done up to the code previously, they found 2 more leaks in our house (that explained the water bill , ouch) and regardless the area being very hard to reach and under the house, they fixed all 3 things on the same day. We very much appreciated their help and honest work. Highly recommend them !

Professional & courteous. Installed a waterline to new fridge, changed valve for new dishwasher, repaired a toilet and fixed a sink drain. Even moved the old dishwasher for us. Highly recommend their services.

Aaron and his dad saved the day for us! We had a gas leak in our home line and they came out right on time and fixed it for thousands less than we were figuring we'd have to pay. They were super nice and professional. They were both very knowledgeable and knew exactly what the problem was. We will definitely use them for all of our future plumbing needs! Call them for your plumbing needs too!
