"torn between 2 &4 stars but went with 2 only because I feel the cost exceeded in my opinion a reasonable cost to replace with a basic 40-gallon electric hot water heater based on the cost I paid two months ago to have a new eclectic 70-gallon high efficiency heat pump water heater and expansion tank installed. We had no time to shop around.... 4 stars for the prompt repair and 2 stars on the pricing."

Bob has been in business for 50 years. Started working on his own property and was disappointed in the quality of other people's work so he decided to go leave a career in electronics sales and into business himself.Became a career in building and developing.Built subdivisions.Built roads and all site work for new homes.

"Amazing work from start off consulting through the end of the project. Very well rounded crew and amazing customer service. They kept me informed of the project every step of the way including when they were finding some damaged pipes under ground that we were not aware of. It reminded me of the type of contractors from home where I grew up in the South that were not out for the money but instead were in the business because they like the work and they love helping people accomplish their dream landscapes."

"Worst homeowner experience of my life. Hired to replace a sewer line from my house to the street - three day job turned into three weeks - said they didn’t need to shut off our water, though we asked, then broke the water line and flooded the hole, which backed up into the broken sewer line and then back into my basement - city engineers were all over the job because of safety concerns, including a teenage boy working in a 12 foot hole with no cave in support. I doubt the city of Dover would even give him a permit again. - never worked a full day. Left early for reasons ranging from broken equipment, teaching karate lessons, or going to daughter’s events - hole was definitely not packed back in correctly as we ended up with a moat the following spring. A pizza delivery guy literally fell into the dent in my front yard. - cost of job went up 150% from original quote and he wouldn’t itemize the bill - and here we are a year and a week later and my sewer line is backed up again so the job was bunk. I’m not even kind of surprised. Dana is the worst. Stay away from this business. I will be filing complaints with anyone and everyone who monitors these types of business. Horrible."

Septic tank services FAQs

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 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.

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.
