"Alex is incredibly honest, pragmatic and helpful. He assessed our community’s potential need and proceeded to discuss any potential restrictions on drainage with the county. We are restricted due to the infrastructure in the proposed drainage area - his thoroughness lost him work but gained our respect. We will look to him for any and all similar projects in the future."

Family owned and operated, Dano's Septic also provides services for portable toilets and rentals, single units, ADA handicap approved portable units and stand alone wash stations. Our technicians are friendly, professional, certified and are ready to provide you with the best septic service to keep your septic out of site and out of mind.

"ORGINIAL POST: DO NOT USE THIS COMPANY!!! After spending over $2,000 on pumping, inspection and camera work, I had one simple request- WAIT 30 DAYS BEFORE SUBMITTING FINDINGS TO THE COUNTY! We were trying to work the problem. I called TWICE about this and was told both times, no problem, we will wait. They submitted it this morning. Because they did not respect my wishes to wait, I now have to pay over $20,000 through the county when we had a plan in place to avoid that and get it fixed independently. Go with a company that follows instructions, not absolutely ruins your life. Thanks for the 10 year debt I will now have due to your negligence. My realtor and contractor will be referring all other agents and all clients elsewhere, and notifying them all of this unprofessional behavior. EDIT: Here's how I would have expected Serena, the office manager I spoke to today to enter the conversation: yes, you're absolutely right, we did breach agreement, how can we make it right? Here's what happened: per her: "there was a human error that was not our fault. The result would have been the same no matter what" (no it would not have and she has no way of knowing that). "I have you on record asking not to submit it at all" (I told her yes I did say that, then asked what's the extension period, and we're getting off track). "Here's the history of your septic system" again no, we're getting off track. You admitted three times in this conversation you breached our verbal contract. You say the results would have been the same no matter what, but that's absolute garbage- no way she'd know that. If you truly have nothing to hide, and know you messed up (which you admitted to) send me the phone recordings I requested not respond "we will be happy to do that upon getting subpoenaed.""

Excavation services FAQs

Unfortunately, some plumbing scenarios, like a broken sewer pipe repair, will require excavation to complete the job. Plumbing excavation costs range from $30 to $70 per cubic foot. However, if you need additional trenching, expect to pay an extra $4 to $12 per linear foot. Keep in mind that these costs are on top of the plumbing repair costs, and they don’t account for labor costs. Consult your excavation specialist to determine an accurate estimate for your job.

The average cost for pool excavation is $2,500. This cost can range from $450 to $4,500, depending on the pool shape and size, time of year, and any need to move buried utilities. 

When excavating for your pool, you might have to move existing utilities. You can expect to pay an additional $15 to $25 per linear foot to move gas lines. To move a septic system, it’ll cost an additional $2,000 to $20,000. A pool that is 10 feet by 12 feet averages $450 to excavate, and a 20-foot-by-40-foot pool averages $3,020.

The cost for residential excavation is $3,200 on average, ranging between $50 and $200 per cubic yard. Total costs could range from $500 to $15,000, depending on the project type, yard size, and soil type. 

When a project needs an excavator, the contractor will subcontract one as part of the larger project. If you hire an excavation specialist, you can expect to pay between $40 and $180 per hour. When excavating, if you have soil with excessive rocks or clay deposits, expect an additional cost of $200 to $1,200.

Warm weather seasons like spring and summer are ideal times to excavate due to the ground being softer and easier to dig through. However, it is important to note that bad weather, like heavy blizzard conditions or torrential rainfall, can prolong the project length, increasing costs. That’s why it’s best to avoid excavating during winter or hurricane season, depending on your home’s location.

While completing an excavation project yourself is possible, we don’t recommend it. You’ll likely need to buy or rent the equipment necessary for the job. This equipment costs as $100 per hour or $2,200 weekly, increasing by as much as 50% for larger jobs. 

In addition, completing an excavating job yourself poses a safety risk. If proper marking hasn't occurred, you risk hitting buried cables and other critical piping, like gas and water lines. Additionally, if working with excavation equipment, you’ll need to steer clear of any overhead wires. Leaving this project to an excavating professional is best.
