"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."

"Don Morris is an amazing individual. I've been calling contractors for my septic system and for other work for weeks. He is the only one who consistently returns calls. Additionally, he is punctual and direct. He doesn't pull any punches. His pricing is amazing, and a very pleasant surprise. He and his crew showed up on the agreed upon date, and they went right to work. Within three days, they had everything finished, including delivery of a truckload of loam. I couldn't be happier with the work they did. I wouldn't hesitate to recommend DJ Morris to anyone.

"Bill and team were the first of several contractors to respond, the most detail-oriented and highly communicative, the most fairly priced (middle of the pack, not too high, not suspiciously cheap). Very easy to deal with. Showed up as promised, on-time, and did the job efficiently."

"David arrived within three hours after contacting him concerning a collapsed septic tank. He coordinated with town health department and completed job in timely manner, leaving the various areas he excavated in clean and tidy condition. The project was very difficult as he had to excavate right next to basement and foundations, and was a very confined space. David responded immediately to phone and text messages, and always kept me informed."

"At first it was suggested that the whole commode be replaced, but it was found out that the bowl was intact and that only the tank be replaced. This replacement was done and the new unit worked fine and nothing else was needed to be done. Great service, good workmanship and will recommend this company to others."

Septic Tanks FAQs, answered by experts

To determine the right size for your submersible well pump, find your well depth, water demand, and well casing diameter. The pump should match your well's specifications and meet or exceed your drawdown and pressure requirements. 

For precise sizing, make sure to research the different well pump sizes, consult the manufacturer's recommendations, or seek guidance from a professional well pump installer.

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.

Septic distribution boxes, also called D-boxes, tend to last over 30 years if taken care of extremely well. In most cases, however, they tend to last anywhere from 15 years to 40 years. Regular cleaning and maintenance, as well as living in an area that doesn’t flood the tank or the system regularly, will all have an impact on the lifespan of the box.

Your septic tank naturally contains the beneficial bacteria it needs to function, so you typically don't need to add more. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three overripe tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many experts consider them unnecessary and potentially harmful. The most effective way to maintain a healthy bacteria population is to avoid using chemical drain cleaners, which can kill the good bacteria in your system.

Yes. Amongst the four most common types of septic tanks—plastic, fiberglass, concrete, and steel—those made of concrete are the most expensive. This is the case for a few reasons, including the fact that they’re very heavy, so pros have to use specialized equipment to install them. However, they’re also incredibly durable, making the price worth it if it’s in your budget.
