"He replaced outdoor plumbing for spout and did some took off some siding of the house. He did an excellent job and provided a very reasonable price. He give free estimate and he come back 2 days later and got finished the job . H e was all work and no talk and had no delay. He was spectacular .and He knew how to access 35 year old pipe that was in the siding. It was great. He place everything in perfect edition and I'd even recommended him on the app next door. I even left his name for others to contact for general contracting needs. I plan to call him again."

We are a family business that has been around for almost 50 years. We install residential and commercial water wells, pump installation and repair, water filtration and geothermal boreholes and system installation.

"These ladies came out today (Saturday of Easter weekend) on an emergency call and determined we needed a new relay. They didn’t try to sell us a new pump but given the fact that the pump was most likely the same vintage (37 years old) we asked them to install a new one. They were professional, knowledgeable and fast! We would highly recommend them to anyone needing well work. The price was reasonable too! Thank you ladies!!"

FAQs for septic system installation and replacement projects in Nassau, NY

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.
