"We had a collapsed septic tank according to our home inspection. Bill Farley saw the urgency and had the tank replaced as soon as possible (a couple of weeks). He not only replaced the tank .. he repiped the inlets/outlets where the previous local company who serviced the tank had done it wrong. Bill was easy to deal with, fair and gets the job done the first time. Process was not stressful .. they takes care of everything and leave things better than before."

"I hired Art to help level out my backyard, and unfortunately, I had a really disappointing experience. He started the job but left it incomplete and in worse shape than when he began. The yard was left uneven and messy, with piles of dirt scattered around and no clear plan for finishing. Communication was poor throughout, and despite several follow-ups, he never returned to complete the work. I regret hiring him and wouldn?t recommend his services to anyone looking for a reliable or thorough job. "

FAQs for septic system installation and replacement projects in Denville, NJ

Depending on maintenance and environmental conditions, septic distribution boxes last between 15 and 40 years. With excellent care and regular system maintenance, these components can function properly for over 30 years. Factors affecting longevity include soil conditions, proper installation, regular septic tank pumping, and avoiding excessive water usage that might overwhelm the system.

Warning signs of distribution box problems include unusually lush or soggy grass patches over your drain field, slow-draining fixtures throughout your home, and unpleasant odors in your yard. You might also experience plumbing backups, gurgling sounds in pipes, or multiple drain clogs occurring simultaneously. These symptoms indicate that wastewater isn't being evenly distributed across your leach field lines.

Most standard homeowners' insurance policies don't cover septic distribution box replacement when damage results from normal wear, age-related deterioration, or poor maintenance. Coverage might apply if damage occurs from sudden, covered events like falling trees or vehicle impacts. Some insurers offer optional septic system endorsements for additional protection. Review your specific policy details to understand your coverage options.

Septic professionals recommend having your distribution box and overall septic system inspected every two to five years. Some homeowners opt for more frequent checks, especially if they've experienced previous issues or have an older system. Regular inspections help identify minor problems before they develop into major failures requiring complete replacement. These preventative evaluations cost between $100 and $200.
