Navo & Sons is your go-to for septic system expertise. Navo & Sons - a modest start indeed.
Founded in 1958 by George Navo, Navo & Sons started with the phone number NC44. Business was initially run from George's residence on Mc Courtney Rd. in Grass Valley for several years. Thanks to hard work, honesty, and reliability, Navo & Sons grew over the years.
In 1973, the business moved to its present location at 815 Idaho-Maryland Rd. as part of a plan for a ""main street"" presence.
During this period, George's son Randy became involved, concentrating on sales and service. Mark Navo started full-time at Navo & Sons in 1976, and alongside George, the Navo brothers broadened their septic pumping service territory.
Jaye Deen Navo joined the Navo & Sons family in 1982. Recognizing the need for diversification, Navo & Sons acquired the Grass Valley & Auburn Roto-Rooter Franchise in 1988 and 1993.
The Navo family achieved their Contractors State License in plumbing and sanitation systems in 1995. Since 1958, the Navo family and their team have been serving Nevada and Placer Counties. With four generations of experience in pumping and septic repair services, no one knows septics in this area better than us.

Were called out for a leak under the Kitchen sink on a 2 story home. The living space is above the garage is 2 beds and 2 bath rooms with a laundry room upstairs as well. One home owner was in the process of passing in the home, his wife, (88 years old) Signed the contract for the leak under the sink and actually ended up signing a contract to re-plumb the complete home. (Built in 1980 with copper plumbing). In 4 or 5 hours Navo and Sons (DBA Roto Rooter,Idaho Maryland Road) tore up the home, tore out the sheet rock through-out the house and overhead in the garage and RE-PLUMBED the whole house instead of fixing the leak under the sink at a estimated cost of $14,000. leaving her with a THRASHED out House as they ""Don't do sheetrock or paint"". One week later her husband died in the home, reducing her income to only Social Security. She now has no food, no propane, a devalued house and a massive lien on her home for a leak under her sink for the unpaid balance due for a complete replumb of the house to fix a leak under the kitchen sink. (She already gave them over $6,000. plus$$ that she doesn't have. Have pictures, wish I could post them here. LONG TIME LOCAL COMPANY WITH NOOO FAMILY VALUES!! Call ANYONE ELSE. Ask your local hardware or plumbing store for references.

Quick response. Friendly, knowledgeable and efficient. They took the time to show me the problems and explain how to avoid them in the future. Very reasonable. I have already recommended them to one friend and will continue to recommend this dependable company.

Always consistently good and honest service. I have been using them for several years on both big and small jobs. They are always very professional.

I called for a pump out for my area. Was originally told by the 1 800 operator that they weren't sure they'd come to my area. Got a call back about 15 minutes later saying yes, they would come and would give me a call back the next day to schedule.
The next day they do call back(deserving of one star instead of none i guess) telling me they will not come to my area. Despite my offer to pay them their hourly charge just to drive to and from my area. They said no. I asked what would it cost to get them here. They said they wouldn't, no matter what.
Pretty sad. Guess they have way to much money already and dont have a few hours to spend to make a few grand for a 200 gallon pump out.
Find someone else would be my advice.

Unfortunately no minus stars. These guys are the worst They certified a septic system for the seller and when it failed admitted that several years earlier it had failed! And I was stuck with the very expensive bill for a new system.

Be aware that Navo's charges $45 for estimates. They didn't tell me this when I called and scheduled an appointment, and I was really surprised when the technician wanted to charge me. I didn't pay, so I didn't get the estimate for a new water heater. I have never been charged for estimates for any of the other work I've had done on my house, including the other company who came out to give me an estimate on the water heater. You might want to just deal with companies that don't charge for estimates, since there are a number of plumbing companies in this area

I just had my first experience with Navos. The man my husband spoke with was very rude. After calling our realtor and several friends to ask which company we should contact (about inspecting an old septic and installing a new septic) they all confirmed that Navos has a reputation for being a real pain. We intended to use Navos but now we are reaching out to other companies and having a much more positive experience.

Fair ,Honest, Knowledgeable, and great service (Josh & Rod) What more can you ask for! Would DEFINITELY recommend this company!!!
THANKS GUYS!!!!

We called Navo & Sons on Saturday. Stan called us back and was here when promised on Sunday morning. Our tank had not been pumped since it was replaced when we remodeled 12 years ago, and we were expecting a mess. Stan was extremely pleasant and helpful, giving us great suggestions. The cost was also much better than expected. We would definitely recommend Stan and Navo & Sons to anyone!

We had them pump our septic tank today (8/30/13). They quoted me $800. And only charged me $695. Now that doesn't happen very often! Honest company. Thank you!
