"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

Buying a well drilling kit will save you money over hiring a professional. That said, digging a well is risky. If you make an error, you may have to get help fixing it. Also, the DIY costs are still pretty hefty when considering everything needed to complete the project successfully. You’ll need to account for the permit, pump, water tank, and more. If you don’t feel comfortable taking the necessary precautions to tackle this on your own, go with a pro.

Concrete septic tank risers are heavier and more durable than plastic or fiberglass ones, making them suitable for long-term use. Installing a concrete riser differs from installing plastic or fiberglass risers primarily in the materials and methods used. The process involves cutting the concrete risers to the required length and then stacking them, using concrete sealant or adhesive between sections for secure attachment. Due to their weight, extra care is necessary during leveling and the attachment of sections. Concrete sealant or adhesive may also require a curing before the riser is ready for use.

Over time, your septic tank can accumulate a buildup of sludge at the bottom of the tank. If left unpumped and uncleaned, the sludge will back up into your pipes and home, causing failure and extensive (and smelly) damage. Repairs to your septic system can be costly, which is why regular maintenance is required. It takes about 30 minutes to pump a septic tank that’s 1,250 gallons or less or 1 hour for larger varieties.

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.

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.
