"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."

"Mr. Stillman was so very easy to work with. He studied the scope of the work which involved replacing about 165 ft of leaking gas lines. PG&E discovered the leak And shut off the gas to both homes on our property. We contacted Discount Plumbing in Manteca but they couldn' t be bothered to provide an estimate. We also had Knight Plumbing out from Stockton. They quoted us over $12,000 and actually told us to consider changing over to propane. The 15 ft job done by Discount Plumbing to get gas to the first house cost $1,450 and the union wasn' t even on the side it belonged. Mr. Stillman explained the entire job and completed it in less time than it took the other companies to prepare their quotes. The entire bill was under $6,800 total. He worked all day, every day and understood that by the time we found him we had been without gas for four weeks! We will always call Mr. Stillman if we have additional plumbing needs and strongly recommend him to anyone who is wanting an excellent job done for an excellent, faiir price.."

"Very well, he came out last Friday, they were on time. Armin Rios was very thorough, very confident and very clean and he replaced the pipe. We hadn't asked for him to replace the pipe, but he said this pipe needs to be replaced he was very efficient. He installed a garbage disposal and a faucet."

"They were able to come out on one day's notice and install a gas line for a gas stove. The gas line works and they seemed to know what they were doing. I didn't really compare rates as we needed to get the work done quickly, so I can't speak to that aspect. Friendly, communicative ... and no problems."

"Original estimate and proposal was handled in professional manner. Everything was fully explained and there was no pressure or "snow job". Everything was itemized and put in writing. The "free" hot water heater was not needed so received a credit of $1300.
The five man crew arrived on schedule and got to work immediately.  Met with supervisor Mark and foreman Jose and reviewed job.
The crew laid down tarps for dirt control (looked good at first, but wasn't that effective. Attic insulation was still tracked in house  They did attempt to vacuum everything up.)
Crew didn't have a ladder so they used mine. No big deal.
They all worked really hard and there was no loafing around. Had the walls opened and new pipe laid out and ready to go the first day.They didn't hesitate in working late. Made the ordeal of having to have a re-pipe bearable. It was great to still have water all day and that night.
The crew were very polite and friendly and we enjoyed their presence.
They really appreciated the free lunch we gave them and helped cement our relationship. They all deserved a "Gold Star" for their outstanding work.
The next day layout was completed, old pipe removed and new tied in. New piping was flushed and  pressure tested. No leaks.
As a former building inspector, I was very impressed by their professionalism, work ethics and attitude. It's very rare to have someone "do it right the first time".The following day the drywall came and repaired all the walls that had been demo'd. Outstanding job.
 Only a few negatives:
Cleanup. 
Attic insulation that had been pushed aside was not put back.(still not done)
They also missed some shock absorbers which the building inspector caught. Jose came back the next day and took care of the them.  Bathroom exhaust fan had been stepped on and pushed down below the ceiling. Drywall man attempted repairs. OK..
Piping could have been flushed a little longer to get all debris out. Minor.
Overall I am very pleased with the work. Price was a big OUCH!
UPDATE!
It has been several months now and I find the installation was not as great as I thought.  Rather than moving the ceiling insulation, they installed the pipes on the roof rafters. Pipe insulation inadequate; water too cold in winter and scalding hot in summer. Don't let them take short cut!

FAQs for gas piping projects in Discovery Bay, CA

Plumbers with proper licensing and credentials install and relocate gas lines. When hiring a professional, verify they have experience with gas systems and all required certifications. Some homeowners choose to work with plumbers specializing in natural gas installations, as they have extensive experience with similar projects and understand the safety requirements.

The timeline for gas line relocation varies based on project complexity, permit processing, and inspection scheduling. The physical labor takes a few hours to one day, depending on the line length. However, the actual installation work represents only part of the overall project timeline. Your contractor should provide a specific timeframe based on your circumstances and local permitting requirements.

Your gas supply must be shut off during the relocation process. This safety measure prevents gas leaks while connections are being modified. Plan for this temporary service interruption by making alternative arrangements for cooking, heating, or other gas-dependent systems in your home. The shut-off generally only lasts for a portion of the work, often a few hours.

Relocating gas lines to connect new appliances is a common reason for this type of project. Whether you're installing a gas stove, fireplace, dryer, or outdoor grill, a professional can determine the best route for extending your existing gas system. The cost will depend on the distance between your current gas line and the new appliance location.

Gas line work is not suitable for DIY projects. Natural gas is highly flammable and potentially lethal if not handled correctly. Gas leaks can be difficult to detect without specialized equipment. Professional plumbers have the proper training, tools, and experience to safely relocate gas lines while ensuring compliance with local building codes and safety standards.
