"I sold my home and during the inspection we identified the system had failed. An engineered plan later and a quick call to JP Martin Building Co (AKA AJM Septic) and we had an installer. We were able to go to closing with a plan and quote in hand and do the work post closing. Work was done quickly and professionally. Both buyer and myself were happy with the work done including a slight plan revision mid build. Great customer service and very ethical. A really great team to work with. I would recommend them to anyone."

"Steve called me within an hour of my request and was at my house within hours. He guided me through the process, handled all of the permitting process from inception through inspection. He dropped the new tank within an 1/8” pitch. He’s an exceptional machine operator and completed the job during the hottest days of summer. BY FAR Fenn was the most reasonably priced contractor. My yard will be better than ever as soon as the grass grows back… Steve evened out the topsoil and removed all of the surface rocks. Can’t say enough good things about the job and its timeline. "

E. Garrity Water Solutions, LLC. is a family owned and operated business. We take pride in are work and use the highest quality products. We offer 24 hour service, 365 days a year. We provide 0% financing to qualified buyers.

"Three years later we're still dealing with the fallout from Garrity's shoddy work. We hired them to install a pump and sensor system to supply water from a new dug well. They consistently cut corners and over-charged us. We have had to hire another company to fix the issues they created (for instance, the pump controller shorted for the second time last week, and each replacement has cost > $1,500)."

FAQs for septic system installation and replacement projects in Norwalk, 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.
