"My septic tank was over flowing. The drain pipe was obstructed. I call my normal guy on Thursday no response. Friday came and went. Saturday, still no response. Went to Home Advisor and with in an hour Innovative called and gave me a time they would be there. They pumped the tank and cleared the drain pipe. I was expecting a major expense but they were just fifty dollars more than the regular guy - who still has not responded to voice messages left on his emergency number. I appreciated the quick response, the complete job, and a reasonable price. I will be using the company going forward. Exceptional customer service."

"Mr Washington personally examined my old concrete driveway, measured its size, calculated the price estimate based on the square foot area of the project, and provided a senior discount. He described the work in detail. He answered questions by email. He came with two workers on schedule to break up the old concrete driveway and haul away the pieces. The next day the same group graded the base of the driveway, placed a wood frame around the edge of the driveway, and directed the concrete pour from a sub-contractor's cement mixer truck, The first three workers spread the concrete while a fourth worker flattened the concrete to the top of the frame. The surface of the concrete became level near the garage and had a gentle slope to the bottom of the driveway. The next day, Washington Boyz cleaned up to lawn, removed the wood frame, and put down some topsoil and grass seeds next to the new concrete. Since the sub-contractor cement mixer operator dumped some excess cargo on the lawn after the cement was poured for the driveway, Washington Boyz had to break up the dried concrete from the lawn and clean up the pieces. Before they left, I was told not to use the new driveway for at least one more day to let the concrete cure and they put yellow tape over the bottom of the driveway to keep the driveway from being used. The final price was the same as the estimate and I was very pleased with the work that was done."

Septic Tanks FAQs, answered by experts

Options include submersible, jet, and centrifugal pumps. Choose based on water needs and well depth.

Consider site conditions, soil type, required capacity, and system designs compatible with environmental protection regulations.

The disadvantages of having a well include more maintenance, like annual testing and inspections, and high up-front costs to drill a well. Well water is also vulnerable to contamination, which is why keeping up with testing is important if you own a well. When it comes to well water versus city water, well water does offer more independence and is a reliable water source.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

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.
