"John Bensavage is AMAZING! He's experienced and cares about doing the best job possible. Additionally, he leaves the job site in better condition than when he started the job. If I could give John a higher rating than 5 stars, I would. If you're looking for the right company to install or repair your septic system, hire John Bensavage, I can't imagine any other septic system installer doing a better job. Elizabeth Martin"

"I do not hand out 5 star reviews just because. Steve and his team exceeded expectations. He replaced a septic tank and installed a dry well system just before the sale of my home to satisfy conditions to buy and he completed the work impeccably with minimal impact to the yard. He was exceptionally strategic, clean and neat while doing the work where others were making no promises or guarantees. I canâ t say enough good things about Fenn Construction."

"The two men arrived on time, were courteous and expedient. They replaced my faucet and showed/explained what they had done before leaving. Shortly thereafter, I am experiencing a leak in my basement which may/may not be related to the project. If it continues, I will call them out to investigate the issue."

"Jason was prompt and helpful and was very flexible in changing or modifying the nature of some of the work before starting. He did virtually all the grading himself and knew exactly what to do. The work was done on time and as specified. I will surely contact him if I need drainage work for another project."

"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."

"Drainworks of Columbia CT solved a serious septic system blockage at our home in Hebron when no one else would. After a quick call to set up an appointment Justinâ s team were at our home first thing the next morning. They diagnosed the blockage problem using cameras and newer technology that permits them to work faster and more efficiently than others. Then they brought in a crew and the equipment to fully clean out the blockages and repair our septic system. They worked tirelessly and cheerfully all day in a cold rain until they completed the repairs same day. Wow! Consider me a DrainWorks customer for life."

"I purchased an deal for $99 for 2 hours of labor.  Originally I intended to apply the time toward replacement of a shower faucet, but the same week, three gate valves in my basement began to fail.  Lew was very responsive and able to accommodate my schedule, and replaced all three valves with ball valves as well as the piping in the area.  I purchased an additional $150 worth of parts from Lew which are warrantied for a year.
What I appreciated most was Lew's evaluation of the shower faucet, which he looked at while he was at my house.  He pointed out that the faucet that I had purchased would not meet my long-term needs and made recommendations so that I could purchase (on my own) a model that would be better for me.  He also gave a very rough quote for the labor that would be required.  Lew could have just installed the faucet I purchased and waited until it failed in another year and installed another one and made twice as much money, but he didn't.  I'll certainly have him back again.

FAQs for septic system installation and replacement projects in New Britain, CT

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
