"David did a great job with our septic replacement and installation. He came in with the best quote. He was easy to communicate with and everything went smoothly. He did a wonderful job with the landscaping after the installation was completed. The grass grew back quickly. We wish we had done this sooner. Would definitely recommend his services. "

"My house is on a little bit of a hill. Over the years, the retaining wall and brick columns lean out. I had just asked Franky to push it all back and repair the brick columns. This was incredibly difficult because of a concrete slab in one section and a large chunk of concrete attached to the bottom of the wall in another section. He had to repeatedly pushed and pushed on this wall until it was in the original position. After that, he drilled holes in the walls, the brick columns and the slabs, then inserted rebar and poured concrete to tie it all together. This was not part of what I asked him to do, but now, thanks to his hard work, this wall is probably 10 times stronger than it's ever been. In addition to that, in our sweeping up the area each day, I had pointed out a section of the sidewalk where one section was sticking up about an inch higher than the other, creating a big trip hazard. This was the city's responsibility, yet he took the time to do a very professional repair that I'm sure the city would be very impressed by. As I mentioned, this is one of the hardest working guys I've seen. You won't be disappointed by his work."

Septic Tanks questions, answered by experts

Septic tanks aren’t bad for the environment as long as they receive proper maintenance and attention. This means staying up-to-date with professional septic system inspections and septic tank pumping. Without regular maintenance, parts of the septic system could break or stop working, potentially letting harmful waste into the soil and groundwater.

Yes, shower water does go into the septic tank. In fact, all the water you use in your home goes into the septic tank. This includes water from sinks, the dishwasher, the washing machine, and toilets. This water is called greywater. It’s important never to put oil or harsh chemicals down any drain because they could cause a clog in your septic system or even disrupt the natural bacteria needed for wastewater management. 

Yes, you can pump a septic tank too much. The ideal pumping schedule varies based on capacity, water usage, and household size. If you pump the septic tank more frequently than your recommended pumping schedule, the beneficial bacteria can leach into the drain field, causing an imbalance and solid waste build-up.

Septic tank lids may or may not be buried in a yard. Most lids are buried at least 4 inches deep unless you have an aerobic septic system. Aerobic septic systems need frequent cleanings, about every four months, so it’s best to leave these lids aboveground for easier access. For buried lids, homeowners can use risers that make it easier to locate and access a buried septic tank lid.

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more.
