Customers say: True professional

"I tried calling several other companies but they didn't get back to me in a timely manner. Derrick called back within an hour and set up an appointment for the same day. Once he tested the system it was clear that the pump and tank needed to be replaced. He changed the pump that day (Monday) and said he would return at 9:30 on Wednesday to replace the tank. He arrived right on time, replaced the tank, gave me a complete explanation of what had been done and the warranties on the pump, tank, and labor. The only thing I might suggest is that he should discuss the estimated cost of the project prior to doing the work and give a more detailed breakdown on parts and labor. Overall I'm very happy with his work and have no hesitation in recommending him and his company."

"Brent and his guys were the best! I am exceedingly happy I selected them to replace my septic tank. This was a major project for me that had the potential to delay the sale of our home. Brent & company came in with the knowledge, equipment and skills that were required to complete the job professionally and efficiently. There was a couple of unforeseen issues but Brent was able to resolve them without batting an eye! He also absorbed the added costs on his own even though I offered to split the difference. I had contacted a number of other firms top do this job and Brent came back with the most professional and detailed quote. He then came out promptly for a site survey- something most of the others did not deem necessary. I have worked around construction contractors for decades and pesonally feel that Fox Excavating LLC is one of the best I have seen!"

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

"Mike has done every aspect of site work for me over the last 20 years. From digging basement foundations to installing sewer and water mains as well as driveway prep, final grading and septic. Mike is a “ can do” contractor with a very positive attitude who shows up early and stays until it’s done. I highly recommend him for any project big or small"

Septic Tanks FAQs, answered by experts

A septic tank lid is often 1 foot underground, but it could be just 4 inches from the surface or 4 feet deep. For septic tank lids that are closer to the surface, you’ll have an easier time locating them just by looking for signs in the yard or using a metal probe. But for septic tanks that are buried deeper underground, you’ll need to hire a pro with specialized equipment to track down the lid without risk of damaging utility lines.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

Choosing a reliable septic tank company starts by finding an experienced company in your area with positive customer reviews online. You can also use the following tips to help ensure you have a positive experience:

  • Choose a company that is licensed and fully insured

  • Ask the company for customer references

  • Ask if the company provides any guarantee for the repair

  • Determine the provider’s level of experience

The septic installation company must follow several steps to put in a new septic system and leach field. The installer will study your property and determine the best place for the tank and leach field. The site should be away from existing structures, be free of trees, and have proper drainage and grading. Preparing the site for the tank and leach field will require significant excavation work.

While not strictly necessary for your septic system to operate, septic tank risers are a highly beneficial and wise choice for homeowners. They provide easy access to your tank, which makes regular maintenance, inspections, and addressing issues significantly easier and less labor-intensive. By eliminating the need for repeated excavation to locate the tank, risers can save you money, labor, and energy in the long run. This easy access allows you to proactively manage your septic system, addressing potential problems before they become costly and ensuring the system's longevity. Additionally, some local regulations may require risers, and installing them can help you avoid potential fines or penalties.
