"As shown in the photos, my kitchen drain line was a mess and needed to be replaced. Cornelius did an excellent job managing all aspects of the job. He showed us pictures documenting the problem and provided us with a detailed estimate. Then, he and his team completed the work on time and budget -- all while working around our time constraints. Throughout the job, he did an excellent job communicating progress and giving us "heads up" about potential challenges. He is friendly, courteous, knowledgeable, respectful, and professional. Without reservation, we will call him again for our next plumbing problem!"

"Jesus did a great job: the house builders installed irrigation that tapped into the water main before the valve into the house, so that a leak in the irrigation system (plastic pipes) meant that we had to shut off water to the house at the water meter at the curb. We had a leak in a buried plastic irrigation pipe, and so we had to do without water until it could be fixed. Jess installed a copper pipe to split off from the main pipe and added a valve, and mated copper pipe to the irrigation plastic pipes, so that if there were a future leak in the irrigation system, it's easy to shut that off w/o having to shut off the whole house. Jesus was on time, did a great job, fixed things quickly, and I'd definitely hire him again."

"I had an old leaky shower that was driving my wife crazy. I changed out the valve washers myself to see if that addressed the problem. Unfortunately that didn't help; and I needed to go to the professionals. Lawrence did a great job at assessing the situation and providing his diagnosis. Throughout the entire process, he was very professional and clear describing the work he was performing and the possible outcomes, given that that my home was built in the 1950s. In the end, it all worked out. Lawrence was a pleasure to chat with."

"Chandlers did a great job. They quoted the repair and got to work. We also added the replacement of the sewer line as the main water line was being replaced. Chandlers added two sewer cleanouts in the front for future access to the sewer and provide a convenient place to empty my RV black tank. I was very pleased with the rapid repair and accommodating the additional work. They made what could have been an ordeal but got it done in 4 days total. I would definitely recommend Chandlers again if the need arises for any other plumbing concerns"

"**Highly recommend FDL Plumbing!** Francisco from FDL Plumbing was prompt, professional, and efficient. He arrived at 10am to diagnose my water heater issue and clearly explained my options. After discussing pricing, we agreed to proceed, and Francisco had a new unit installed by 11:45am, exceeding his initial timeframe. Francisco was a pleasure to work with â he completed the job expertly while maintaining a friendly demeanor. His work ethic and competitive pricing (especially for San Francisco) were refreshing. Thank you, Francisco, for the outstanding service!"

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."
