"Ultimately happy with the end result and fair price for our 30ft sewer lateral replacement. Miguel was professional, friendly, and hardworking. However, communication was a bit spotty and we had follow up many times (I understand this is the busy season, though). Also, it was unclear if we were supposed to call 811; we assumed he would, but didn't, and this was an issue as the water line was hit during construction and the city had to come to shut it off on the whole street. It was handled quickly, but would have been avoidable. The project ended up taking much more time than expected, but it was completed in a day, as promised. I would recommend him, but you should be diligent and responsible yourself to make sure all the right steps are being taken."

"Aurelio repaired a very difficult underground leak in our water main in front of our house, and he did it within hours of being contacted, by using time between jobs for excellent communications in advance, and then working very efficiently, knowing precisely what needed to be done. He was also able to charge a very reasonable cost by pinpointing the precise repair needed, with no attempt to upcharge or sell us on unnecessary upgrades, completely unlike what I have seen other larger companies try to do when we asked for quotes or services. In short, his integrity is as impressive as his skill and knowledge, which are both very great. He then concluded the repair with an immediate and highly detailed invoice that he completed and emailed to me within less than 3 minutes. I was truly surprised at how easy and reliable he made everything work for us, and he was worth every penny."

FAQs for septic tank service projects in Windsor, CA

The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.

Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.

A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.

Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
