"The Deliberate Destruction of a Grandfathered Septic Dry well at a cost of $15,000.00 to Replace! In October 2024 I hired Benjamin Franklin Plumbing of Andover to clear a blocked drain pipe and dig up and uncover my Septic Tank and Septic Drywell and pump the tank. Both are as old as the house and grandfathered. Inadequate compared to todays systems however legal under grandfather clause with no permit needed. Under the guise of Safety They destroyed the dry well without my permission . I am seeking a refund of $12,000.00 to replace it . - My plan was to dig it up and clean it up but it was a lost cause- this puts me in a position of having to install a modern leach field at a cost of 9 to 15 thousand dollars vs. a few hundred dollars to to tie the new septic tank with the old dry well with PVC pipe. Thats why they did it- They were setting me up for the next big payment $$ Now they are claiming it was a safety issue that required them to destroy it ! I am demanding a $12,000.00 "

We are a full service Excavation and Trucking Company with 30+ years of experience. Specializing in Complete Septic System Installation and Repair. New or Failing System we perform perk and have Design Engineers we work with your particular project. Demolition of any Building and removal of debris. We do not perform septic pump outs.

"Septic tanks were left exposed, site was a mess, and vent pipe was not at the required height. We talked with him a month before we anticipated water connection, so he knew our timelines. We attempted to contact him every day for a week to schedule final inspection after water was connected, but got no response. It took two emails from the city for him to sign the certificate of compliance."

Septic tank services FAQs

Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank professional could lead to poor quality work, added future expenses, and potential code violations. A licensed septic tank installer tackling your projects only protects you as a homeowner. 

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified 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

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.
