"Our sewer main busted and Oak Plumbing’s master plumbers Matt & Mike did a great job at digging down over 7ft to replace the broken section and also upgraded my single sewer main clean out which was nearly rusted through to a dual solid ABS clean out. And also I would like to add that Nate also did a great job at identifying our problem! Thanks guys! You’re AWESOME!"

"The free estimate was conducted by phone with Matt.  He answered all of our questions fully, confirming that we did not need to install a larger unit and that all usual pipe and/or valves that needed to be replaced would be included in the quoted price.
The installer, Bobby, showed up within the stated time period, which was only two hours after the initial contact. He got right to work and was efficient, neat, and skilled.  He removed the old unit, took out some unnecessary pipes that were left from an old solar heating unit, and quickly installed the new unit.  He then demonstrated the thermostat operation, which is very different from the previous unit's, tested the operation, and cleaned up the area.
The price was reasonable. The unit has a good warranty (and looks nice ).  The Angie's List discount was applied with no problems.
My husband is a former plumber so he kept an eye on the whole install, and was pleased with the entire experience.

"You would be very glad you called them instead of these other major plumbing companies. They took so much worrying off me and my family mind. They did not try to take advantage of the situations due to its emergency status like some company does. They come highly recommended by us."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"The plumber showed us a trick for how to clear the food trap using the garbage disposal and water pressure, which I really appreciated! He also, with permission, came early so punctuality was great. Only downside is this business is pretty expensive, twice at least what I have paid out prior plumber."

FAQs for plumbing projects in Napa, CA

It depends on the severity of the leak. Minor leaks may not require immediate attention and can be scheduled during regular business hours. However, if the leak is causing significant water damage or you can't control the flow of water, it's best to call an emergency plumber right away. Addressing serious leaks promptly can prevent structural damage and mold growth, potentially saving you money on extensive repairs later.

A journeyperson plumber is a licensed professional with a state-issued permit who installs and repairs piping for water and heating systems under the supervision of a master plumber. They have completed extensive training and amassed significant experience leading teams, drafting blueprints, and designing comprehensive plumbing installations. Their proven expertise ensures that they can handle both routine repairs and complex projects with precision.
