"Mike and his team are extremely responsive and professional. From the first contact to final installation for a large, complex septic system, it only took 2 weeks including all the permit and inspection. We are really grateful for finding Septic Advisor through Angie's list and hired him for our project. We cannot be happier! Highly recommended! Will definitely hire Mike again for any future needs."

"This was the second time that we hired the Main Choice Inspection team. Bill Heath and his team, Kevin and Brian, were excellent. They were punctual and made accommodations to be at both inspections, in spite of a northeaster storm. The inspection(s) included: a general home inspection, sewer line and septic/leach field. The first inspection, post storm, was done in frigid temperatures. That inspection took a few hours and they worked well with the home inspector( from another company). At the end of each inspection; they handed us a manual on home maintenance, gave useful advice and recommendations. They inspect from top to bottom--no cutting corners! As for customer service; they cover their shoes upon entering the home, they respond quickly(phone or email) and will do whatever they can to assist you. We highly recommend Main Choice Inspection, especially for the first time homeowner, they are licensed and certified."

FAQs for septic system installation and replacement projects in Portland, ME

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.
