"We needed a completely re-engineered septic system at our house in Wales, and Ron helped us with every aspect of the project. From his initial recommendation of an engineer who custom designed our system, to the installation of our holding tank, pump tank, and leaching field, Ron exceeded our expectations every step of the way. Ronâ s crew was courteous and professional, his pricing was fair, and I am confident recommending him to my friends and neighbors!"

"By Andrew v. Engineer Dave Schofield of Capstone displayed professionalism by turning a flawed design for our Sudbury septic system into one highly adaptive and functional. He was purposeful about doing the right thing even when not winning installation contract, execution of which he in in fact supervised. In a business which includes its share of uneven performers, Schofield’s competence is a stand-out."

"Hayden first came because my septic overflowed a little--he found the blockage, fixed it, took a video of it so I could see it, and charged me very reasonably--on the weekend! Then he came back, did my Title V inspection and pumped me out. Again very prompt, thorough, meticulous. I highly recommend him. Easy to work with, reliable, *very* responsive."

"Sorry, looks like this review got stuck in draft mode for quite a while. But the good thing about that is everyone gets to read a review with an update 1.5 years later on the quality of the work completed! In late 2020 I had recently moved into my new home and the gas water heater wasn't working properly. It was leaky and at least needed the pressure relief valve replaced, but the tank was well past it's expected lifetime. The techs were very helpful, kind and knowledgeable. The valve replacement wasn't going to work because repairing the tank could damage it further, so the tank was replaced instead. The price was very reasonable and installation was done really well. They did a great job with cleanup too! One and a half years later and the tank has had zero issues! I would definitely recommend them for heavy jobs like this or more simple ones around the house. Thank you very much!"

Septic Tanks FAQs, answered by experts

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

If your septic tank is still within its expected lifespan and you need to relocate it on your property, it's possible to do so. However, because the task is so labor-intensive and costly, most homeowners simply choose to abandon the old tank if possible and install a new system in the new location. In either case, hiring a professional installation company will be necessary for the job. 

A well does not run out of water because the groundwater continues to refill with rainwater that seeps through the ground. If the well is too shallow or there is a drought, a well can run dry or be short in supply. It’s important to have a well deep enough to source enough water for your home’s use. Deeper wells tap into more groundwater reserves. If your well is not producing enough water, you may need to redig your well.

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.

Baking soda does very little to nothing for a septic tank, but it can help unclog a drain or clean out a garbage disposal. Rotten tomatoes and yeast are the best ways to increase the bacteria in your septic tank naturally. You can add these to your system once every three months.
