"We have worked with many plumbers in Los Angeles, and our experience with GMC Plumbing was by far the best. They are responsive, honest and trustworthy. They did a great job and helped us avoid paying the thousands of dollars other plumbers told us would be needed to fix the problem. We highly recommend them"

"Very honest, trustworthy and inexpensive plumbing company. I had three total estimates for the work and the other two companies just seem to want to charge as much as possible and do more work then was needed. I highly recommend Western Rooter and ask for Ryan, he’s the best!"

"I recently had a gas leak scare and called L.A. Plumbing pros. He was fantastic! The plumber who came out his name was Victor he was professional, communicative, and very efficient. He was able to quickly locate the source of the gas leak and explained everything clearly throughout the process. I felt confident in his expertise and appreciated his willingness to answer all my questions. The repair itself was done promptly and the work area was left clean afterwards. I highly recommend L.A. Plumbing pros for any plumbing needs, especially if you suspect a gas leak. Their fast response, clear communication, and quality service were all top-notch!"

"We scheduled an appointment with Johns Plumbing to get an estimate for a couple of non-emmergency issues including water heater replacement and faucet installation. Price was fair and we decided to go with them. Plumbers were working fast, and they completed all the work within one day. I would recommend Johns Plumbing to everyone."

"I have a Rinnai tankless water hater that was not supplying us with hot water, and 2 different plumbers had tried to improve it already. Sev came out and told me Leon Plumbing is backed by the Rinnai company. What a relief! He explained to me the issue and why the things the previous plumbers did made no difference. He was very clear and informative the whole time and even told me my Rinnai needs servicing annually and would reach out when that time comes so I don't forget. Our hot water is running again and I will gladly use Sev at Leon Plumbing again. Professional, friendly, and communicative."

Affordable Plumbers questions, answered by experts

Homeowners in CA frequently underestimate the time required for county permit approvals and final inspections. Opening walls for plumbing repairs often reveals outdated galvanized or lead pipes that demand full replacement. Tree roots easily invade older sewer laterals, creating immediate repair needs. Replacing a water heater also triggers mandatory code upgrades, including seismic strapping and expansion tank installations. Always account for underground utility locating delays before digging on hillside lots.

Helpful?

Sloped foothill terrain in Altadena adds significant complexity to plumbing work, especially for trenching and gravity-fed drain lines. Older properties built between the 1920s and 1960s feature outdated galvanized steel or cast iron pipes that require extensive replacement. Determine if your property uses a private septic system or connects to the county sewer before starting. Finally, elevated mineral content in the local water supply causes scale buildup inside pipes and water heaters.

Helpful?

For plumbing in CA, choose scale-resistant materials that withstand the area's hard water. State law requires low-flow toilets, showerheads, and faucets for all permitted upgrades. You must use flexible connectors for gas appliances and install approved seismic strapping on water heaters to meet strict earthquake safety codes. Additionally, select underground piping designed to handle ground movement caused by the region's expansive foothill soils. All fixtures must meet strict state lead-free standards.

Helpful?

As the homeowner of record in Altadena, you must authorize all permit applications for plumbing work. You hold responsibility for the sewer lateral line connecting your house to the public main, making any repair or replacement decisions your choice. Select low-flow fixtures that fit your style and accessibility needs. You must also decide whether to upgrade to a heat pump or solar water heater to comply with strict energy codes.

Helpful?

Address active leaks immediately to prevent rapid mold growth in older Altadena homes. Missing flexible connectors on gas lines or water heaters pose severe life-safety hazards and require urgent attention. Slow drains or sewage odors signal failing sewer laterals that demand immediate camera inspections. Schedule non-urgent exterior plumbing during the dry season to avoid trenching complications. Replace water heaters older than eight years promptly before hard water sediment causes complete failure.
