"So far so good. Snaking of kitchen sink with very old pipes. Hopefully snake did not poke pipes. Only time will tell. Keeping fingers crossed. They did a good job explaining and triple checked for leaks before they left. Of course they tried to upsell and gave us a metal trap they did not quote us upfront for. We would have chosen it over plastic, but price difference would need to be cleared upfront. That's the only negative. Otherwise, thus far we are very happy with the result. Thank you for coming on such short notice and on time! Super appreciated. 4.5-5 stars."

"Very disappointed. This guy is a crook. I paid way too much for what he did and he did not do the work properly. He replaced pipes that were leaking from our upstairs shower. I had another leak a few weeks after he did the repair. 2nd leak was not related to the pipes he repaired, but the 2nd plumber who came out for the 2nd leak had to cut into the ceiling where HK&S Plumbing replaced the pipes and told me that the work was not done properly. He did not glue the pipes properly and he used a rubber coupling that is not allowed in California. The other plumbing company said they would fix his work for 65% less than what I paid HK&S. When I asked HK&S about all this, he gave excuses about the small space and how much more work it would have been to do the work the right way. When I asked him again for a refund, he is now saying his work will last "forever" (really?) and has nothing to say about what he did wrong. He is not giving me a refund. Not sure I will use anyone thru Angi again."

Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

Gas Leak Repair questions, answered by experts

Earthquake gas shut-off valves, or seismic gas shut-off valves, are safety devices that attach to your natural gas line. When an earthquake hits, the valve automatically turns off the flow of gas. Earthquake gas shut-off valves can prevent gas leaks, which are especially dangerous after a quake due to the risk of fire and explosion.

To ensure a steady propane supply, schedule regular deliveries with your provider, monitor usage, and consider keeping a backup supply for emergencies.

Having gas appliances in your home can be convenient—you benefit from faster water heating, more efficient clothes drying, and more affordable home heating. However, you need to be aware of the signs of a gas leak so that you and your family can take precautions to be safe around these versatile appliances. 

Signs of a gas leak include:

  • Hissing sounds

  • Rotten egg smell

  • Higher than usual gas usage

  • Physical symptoms, such as headaches, dizziness, and nausea

In some cases, the answer is yes. Being licensed to work on gas lines requires additional specialized training beyond being a licensed plumber. If the plumber is also licensed as a natural gas plumber, they will be able work on natural gas lines. If the plumber is only licensed to work on water and sewer lines, then you’ll have to find another professional to do gas line work.

Yes, it’s possible to convert an oil furnace to gas. However, you may have to replace the furnace completely instead of simply converting it. If the original oil furnace has had any type of damage or is older (typically considered over 15 years old), then you will likely need a full replacement versus a conversion.
