"I contacted Andy from Area Septic Installation Inc. because I was selling my house and the septic system did not pass the inspection. I normally contact 3 providers to get the best price. Andy was the only one to call me back and to come out to the house. Andy was very friendly, and provided me with great information and no hassle/pressure bid. Because I was selling the house there was a tight deadline on getting the work done. The time of year that I needed the work done is extremely busy and the weather did not cooperate. Andy also took time to explain to me some of the deceptive practices in this line of work and cautioned me not to become victimized. I thought that in and of itself was remarkable that he gave me this information so I would not become victimized. Andy showed up on the day he said he would be there, and got to work immediately. Andy knew that I was on a tight deadline to close and he worked long and extra hours to get the job done. His price was very reasonable for the work that needed to be done. Andy did everything to make this as easy as possible, and did a great job. When the work was completed Andy wanted me to come check the work to make sure it was up to my satisfaction before he left. Andy had the yard looking great back to its natural look. If you are in need of septic work I would strongly suggest calling Area Septic Installation Inc. for the work. Hard workers, Honest contractor, and fair pricing what more could you want. Jim Z."

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks questions, answered by experts

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.

With regular servicing and general upkeep, both a well pump and pressure tank can last for years. The average lifespan of a well pump is around eight to 15 years. A well pressure tank can last from seven to 10 years. How long a well pump and pressure tank lasts also depends on a variety of factors such as type, size, material, and brand.

Normally, when your well pump turns on or off, you’ll hear a small click. This isn’t anything to worry about, but it can be a problem if it’s clicking continuously. This can indicate that the well pump is short cycling—the pump continuously turns on and off.

This can wear out the motor and provide uneven water flow. If this happens, you may need to get it looked at by a well pump professional to see if you need to repair the switch or pump.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.
