"Hot water issue. Technician gave estimate for hot water tank replacement of 8 year old lightly used tankless. In light of the phenomenol price tag, did some homework. Hit the reset button. Fixed. Hmmmm. Maybe it was the tankless that confused him. Really glad it was a free estimate (unlike Len's who charged me $315 and didn't fix it)."

"Tried to schedule a routine maintenance appointment available to customers who signed up for service plans, but Len could not follow through with their commitment three failed/rescheduled appointments in a row!! Each required four hour commitments from the customer. I tried to communicate with dispatch and customer service but unfortunately I don’t think these two departments have an open line of communication between them. I would not recommend for anyone to work with or engage with this company. Len did not follow through on their half of the commitment and disrespected my time as an in office working professional."

FAQs for septic tank service projects in Fort Washington, MD

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.
