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.

"Addendum to my last review: When the septic pump failed, we discovered how many corners were cut. Instead of a septic pump, a sump pump (for rainwater) was installed with the 1½ inch pipe joined to a 2 inch pipe to make it look like it was supposed to. There was no coupler on the pipe leading to the distribution box, necessitating cutting the pipe to get the sump pump out. No check valve. Do NOT use this guy."

Septic Tank Repair questions, answered by experts

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

The price you’ll pay for service from a septic tank company will depend on the specific service you need. Here are some common services, along with average pricing:

  • Anaerobic septic system installation: $3,000–$8,000

  • Aerobic septic system installation: $10,000–$20,000

  • Septic tank pumping: $250–$550

  • Percolation test: $700–$2,000

  • Leach field installation: $2,000–$10,000

These numbers vary based on your septic system size, property layout, and more, so the best way to get an accurate estimate is to contact a septic tank professional for a custom quote.

Depending on the size and location of your septic tank repair job, you may want to let the septic pros finish before tackling other backyard work. However, in some cases, it’s not a bad idea to coordinate between your providers if the timing’s right and your septic repair pro says it’s safe to do so. For instance, if the septic repair work is happening in the fall, you might want to take advantage of the opportunity to prepare your backyard landscaping for winter , or in spring, start mulching the garden beds.

You may be able to neutralize septic tank odors by flushing about 1 cup of baking soda down the toilet weekly, although the best option to banish odors is to have the septic tank pumped regularly, about once every three to five years. 

To minimize odors, only flush human waste and toilet paper in the toilet, and avoid pouring coffee grounds, fats, oils, or grease down the drains, as this could cause clogs. Rather than trying to neutralize a septic tank odor, you should hire a pro to determine the source of the smell, since sewage gas can be toxic.

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.
