Navo & Sons is your go-to for septic system expertise. Navo & Sons - a truly humble beginning.

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.

George's son Randy joined the team, dedicating his efforts to sales and service. In 1976, Mark Navo joined Navo & Sons full-time, and with George, the Navo brothers expanded their septic pumping services.

In 1982, Jaye Deen Navo became part of the Navo & Sons team. Seeing a need to diversify, Navo & Sons purchased 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. No one in this area has more experience and understanding of septic systems than our four generations of service in pumping and repair.

Great communication. Good prices considering other quotes I received. They are very kind and provided a report soon after the septic inspection. I would definitely use them again. Super easy billing as well.

Had to call Navo and Sons for a septic tank issue, from the people that answered the phone and scheduled me to Parker, the tech that arrived at the house, everyone was great to deal with.

Parker quickly got to work and was very knowledgeable and professional. I am extremely pleased with the service and the pricing was more than fair.

Highly recommend.

Jeremy Navo squeezed me in the same day I called. I had bought my current house about 5 years ago and my real estate agent, John Neeb, recommended I call Jeremy to check for roots etc. He pulled up the lid and said it was doing quite well and would not need a service or anything for a long spell I had to force him to take some money for his time. Nice guy!

We have learned TONS moving into the rurals. One is to mandate a septic and leech line map of the property. This does a lot, especially if you want to build something:
1 - nothing is allowed over any part of the septic system,
2- did they use the least expensive thinwall pipe and then plant trees near it, etc.

We bit the bullet and, after minimal searching, contacted Navo & Sons. We asked for pricing on pumping out the existing tank (only 19% sludge buildup - but we want to aerate it), and tracing the leech field. It was a bit expensive, but so is a pumper truck, mini excavator, trucks, manpower.
First crew was the pumper truck, in and out no problems. Not a lot of knowledge about septic systems overall, but the job was to pump out the tank.

Next crew (two days later), was comprised of Kalem and Ben (I cannot remember the first two). Kalem is training Ben, they made a good team. They traced all lines, uncovered two submerged septic distribution boxes (stinking clay pipe - pun intended), flagged the lateral lines and end of runs. Found they had also used CHEAPO thinwall ABS and planted a walnut tree right by it so the roots had broken the primary effluent line. They left the disbursement boxes open as they are 10-12"" below grade and I want to put extensions in.

They covered all end of runs, flagged everything, and will make a map for the county and send a copy to me.

If I had known the status of the system pre-buy, I would have asked for a discount, but the mandated inspection, paid for by the seller, does not require all of the detail.

All-in-all: pumper with two men followed by van with trailer and excavator and two men...we paid $550 plus $1050. We hated spending the money, but it I felt their costs were reasonable. GREAT COMPANY AND CREWS!!

These guys came to our house in 2017 to pump the septic. They came with a huge truck. We have two tanks. They pumped one and said the truck was full and that they would come back to pump the other tank in a day or two. The next day, two guys showed up to look at our septic alarm and fiddled around and kind of fixed it, but not quite. They asked to be paid for coming and for the septic pumping. I said they hadn't finished that they had another tank to pump. They replied no worries. They seemed nice, so I stupidly paid them $635 for coming out and the pumping which was not completed. After a couple of days, I called them about pumping the second tank, they never returned my calls, they never came. I called many times. Nothing. So I gave up. Today-October 2020, another crew arrived from a different septic pumping company. I showed them the tank Navo & Sons had pumped, they noted that the tank was not the one that needed to be pumped. It was the water holding tank and not the one with the solid matter that needed to be pumped. I then told them the above story. They shook their heads in amazement and said I should not have paid for anything, because pumping that tank was like doing nothing. These guys used a locator to find the second tank--a difficult process, and spend a couple of hours pumping it out, shaking their head that the other guys had charged so much and not done this. I would never recommend Navo & Sons. If I could I would give them a minus star, but I can only go down to 1 star.

I called this AM regarding a problem with our septic tank. While no one could come out to pump the tank for over 2 weeks, they sent someone out immediately to see if he could help Us in the interim. He couldn't but I'm grateful he came promptly and explained the problem. We had called 3 other companies and couldn't even get a call back on 2 of them. I really appreciate the effort made to try and help us out. Very courteous and helpful! Thank you.

Keeth was awesome. Called before arriving and arrived early! Wore a face covering as safety is a big issue. He was in and out quickly and very thorough. Explained to me and showed me how to avoid a stall in my garbage disposal should I run into the same issue. Overall, awesome job done and highly recommend!

They do yearly maintenance on our pressure dose septic system. Nice folks, easy to communicate with, happy to take their times and explain things.

They just went the extra mile for me today; our septic alarm went off a week or two after our last inspection. So I called and they were out same day. Flipping the power off and on fixed the problem (at least for now!). What's particularly nice is they volunteered no charge for the service, I assume a courtesy after the inspection. Very kind.
