"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."

"Couldn't have gone better. I didn't know Jake at all when I was interviewing contractors. He impressed me with his responsiveness to my emails and calls. He was here when he said he would be and called ahead as well. I had quotes from three contractors, not only was he the lowest but he was the only one bring in all new material, the others planned to reuse the loan and sand where they could. We took a chance and hired Jake, couldnt be more happy. Our field was failed so we were a family of 5 ( with three teenagers) on water rationing for three weeks during a stay at home pandemic. We needed the work done quickly. He was here in 3 days and finished it 2 days later. In the process we realized we needed to extend a stone wall as a result of the new size of the field. I didnt have a vehicle which could transport that many bricks. Jake had one of his guys pick it up for me with his truck and deliver it to the site, no charge. Really great service, I would highly recommend Farrell Contracting Servives."

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.
