Clear River Environmental is Long Islands Premier septic, cesspool, and sewer cleaning company. From minor service to Compleate installations services, no job is to big or to small. Our family of companies has been serving Long Island with pride for 25 years. We take all major credit cars cash and checks. Mention this ad for special discounts.

"This was our second time working with Clear River Environmental. They installed our new septic tank and leaching pool over a year ago for $7200. I was hesitant to use them again due to their lack of communication with regards to follow-up documents which were required by the Health Department. They attributed their lack of sending me the "as-builts" and other required certifications to having switched over their computers to a new system. Nevertheless, the issue was eventually resolved after numerous calls to their office. Fast forward to 11/19/20....I called them to install a future expansion pool which was required by the Health Department. I figured that they were at least familiar with the property and I had no complaints with the actual install from last time. Long story short...they cut through a gas line to our pool which necessitated a call to National Grid. They also destroyed large branches from a tree, a large portion of recently installed sod, as well as pavers and the curb cutout. Granted all of this damage is listed on their disclaimer, however I was a bit dismayed when they refused to compensate me for any of the bill that was required to do repair work. I understand that the owner is responsible for informing the seller of "underground perils," however I would also expect the professionals to ask the right questions before beginning a job. I would also expect professionals to consider something more than just the "repeat customer" discount to alleviate the buyer from some of the expense and stress caused by the damage of the gas line. This second job cost $5,300. Total money paid to Clear River Environmental = $12,500 . The repair to gas line cost me $900 . The pavers and curb have yet to be repaired."

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