Our services include everything from digging out your old tank to locating your new one, even ensuring your outdoor space is returned to its former glory. Ancient, leaking oil tanks pose a problem for homeowners, often when they come to sell. You might be concerned about the cost of oil tank removal and replacement because many contractors won't give you the final fee until the project is complete. That's where ERC Environmental is different. We quote you up front for the job, so you know exactly how much you'll have to shell out. It won't cost a single cent more. Contrary to popular belief it takes a matter of hours to remove and replace an oil tank – not days or weeks – and you won't be without heat or water during the process. ERC Environmental is a state certified, licensed, reputable and professional oil tank removal and cleanup company. Talk to us about your tank today.

"I had a good experience with the oil tank removal. However, they weren’t clear about charges. I agreed to hire them because in shopping for estimates they were the middle man. However, look at the estimate carefully. If any permits need to be pulled they put “permit”-TBD and charge $150 to obtain the permit. So when I received there estimate I thought that was the complete estimate and there would be no other charges. This was not true. I paid half up front and the other half was due when the job was complete. When the job was complete I had an addition charge of $400 for obtaining the permit and the permit itself. When I explained my situation and asked that they give some type of credit with the $150 they threatened to sue me and put a lien on my house. Do I think it would go that far “NO”. Attorneys are very expensive. However, I will not be referring them to anyone because of the sneaky manner in which they charge and also the threatening manner in which they ended the job. It’s not worth the headache though. If $400 is going to make such a difference I will pay it. Stay away charged are not clear. When they found out how much the permit would cost I believe they should have informed me as well as informed me that it would cost $150 to obtain the permit."

FAQs for septic tank service projects in Syosset, NY

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.
