Navo & Sons, your specialists in septic systems. Navo & Sons - a truly humble beginning.
George Navo established Navo & Sons in 1958, originally using the phone number NC44. Business was initially run from George's residence on Mc Courtney Rd. in Grass Valley for several years. Through hard work, honesty, and reliability, Navo & Sons flourished over the decades.
In 1973, the business moved to its present location at 815 Idaho-Maryland Rd. as part of a plan for a ""main street"" presence.
At this time, George's son Randy joined the business, focusing 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.
In 1982, Jaye Deen Navo became part of the Navo & Sons team. To diversify, 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 employees have provided service to Nevada and Placer Counties. With four generations of expertise in septic pumping and repair, we have unmatched knowledge of septic systems in this region.

Recommended Customer Reviews

OMG - Thank you! While out cleaning my deck, my hose bib decided to shear away from the house and had water gushing everywhere! (I won't go into the details about how that happened...) I called Navo & Sons, as they already service my septic tank, and the woman who answered the telephone must have heard my panic and told me that she would put my name on the ""next"" list for the technicians out in the field. It was about 45 minutes, max, and they were there - yay!
It was only a matter of moments before they had apprised the situation, were able to replace the bib, have the water turned back AND do it at a reasonable cost.
For these reasons, I give them a 5-star rating and they get my ""Heroes Of The Day"" award!

I am not happy with how this whole job went at my property. I only settled because I want the map tracing, since I have already had to wait a week for a manager to even respond to me.
The person working here, hit a pipe and LIED to me and said it was broken before. When I called and talked to the manager, it was in the notes that he hit the pipe. So why didn't the guy tell me he hit the pipe? Then when I'm talking to the manager, he offers to fix the pipe. It happened a week ago! Keep in mind, it took 4 days for the manager to respond back to me. So I was supposed to wait around for a week without water while he took his time messaging me back? Why didn't he just fix the pipe when he knew he hit it in the first place!
He originally offered $100 off which is honestly an insult to me. I eventually settled for $250 because I'm over dealing with this company. I am definitely not gonna recommend this to friends and already told the person who recommended me about the situation. This whole thing could have been avoided if the person working here would have just been honest with us instead of covering his butt.
Ps: it was even more of an insult the manager offering to fix it a week later after they knew it was broken and I already PAID to get it fixed.

Very professional, upfront, and helpful. They knew what they were doing, and never heard a single four-letter word inspite of the complicated job. They were hardworking and courteous and will call on them again!

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.
