"Based purely on these reviews, GMC was the first and only company I called to install a recirculating tankless water heater. I found Geremi to be extremely reliable, and an excellent communicator via text or whatever. He told me in advance when he would arrive, which he confirmed often, he DID show up on time, the job site was clean and the installation was well done. I asked Geremi to come back to our house a few days later to make some minor adjustments to the system. He did so without hesitation and without any additional charges. I have nothing but positive comments for GMC plumbing."

"My family recently moved Fresno. When we lived in LA we hired Johns Plumbing to install a new water heater. It was 40 gallon Bradford White water heater. John gave a free estimate first. Then his team installed water heater. Victor and his helper worked fast and accurate. We highly recomend Johns plumbing"

"I contacted California Drains because my parent's home was completely backed up to the point where dirty water was coming out from the drains inside and outside their home. They promptly answered and booked me in the same day. They were able to contain the water from continuing to come out of the drains overnight and returned the next day first thing in the morning to get the problem fixed. Price was very reasonable, and the workers were very professional. Left everything clean and drains were completely cleared. It has been months since they came and there has not been an issue since. 10/10 will highly recommend to family and friends."

"Esteban did a great job. He made some recommendations based on our needs. He took out most of the old cast iron pipe that was corroded and replaced with ABS black plastic. He also installed a valve, so we could use the wash machine water to water the backyard trees and plants. A goal was to minimize damage to the exterior stucco, and he used drills instead of hammers to go through. He listened to our questions and made some recommendations to avoid leaks. I hired him to do some additional work the last plumber did wrong, and he did it at a very reasonable price. I would highly recommend Esteban Plumbing."
