"ORGINIAL POST: DO NOT USE THIS COMPANY!!! After spending over $2,000 on pumping, inspection and camera work, I had one simple request- WAIT 30 DAYS BEFORE SUBMITTING FINDINGS TO THE COUNTY! We were trying to work the problem. I called TWICE about this and was told both times, no problem, we will wait. They submitted it this morning. Because they did not respect my wishes to wait, I now have to pay over $20,000 through the county when we had a plan in place to avoid that and get it fixed independently. Go with a company that follows instructions, not absolutely ruins your life. Thanks for the 10 year debt I will now have due to your negligence. My realtor and contractor will be referring all other agents and all clients elsewhere, and notifying them all of this unprofessional behavior. EDIT: Here's how I would have expected Serena, the office manager I spoke to today to enter the conversation: yes, you're absolutely right, we did breach agreement, how can we make it right? Here's what happened: per her: "there was a human error that was not our fault. The result would have been the same no matter what" (no it would not have and she has no way of knowing that). "I have you on record asking not to submit it at all" (I told her yes I did say that, then asked what's the extension period, and we're getting off track). "Here's the history of your septic system" again no, we're getting off track. You admitted three times in this conversation you breached our verbal contract. You say the results would have been the same no matter what, but that's absolute garbage- no way she'd know that. If you truly have nothing to hide, and know you messed up (which you admitted to) send me the phone recordings I requested not respond "we will be happy to do that upon getting subpoenaed.""

FAQs for septic tank service projects in Lilliwaup, WA

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.
