"We had a very sluggish flush in our second bathroom, that was irritating my wife. We called in Joe upon the recommendation of my daughter and son-in-law. He recommended putting a collar on our septic tank to make it easier to get it next time, and pumped out our Cesspools. Highly recommended"

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 Smithtown, NY

A septic tank typically lasts 15 to 20 years, depending on the materials used, maintenance frequency, and soil conditions. Regular inspections, proper pumping, and careful water usage can extend its lifespan. Professional maintenance ensures your system remains efficient and helps prevent premature failure.

Your septic tank should be pumped every three to five years. In fact, the recommended interval for pumping is every three to five years, as this schedule effectively prevents the buildup of solids and maintains the system's performance. Factors such as household size, water usage, and the capacity of the tank can influence this interval. Adhering to a regular pumping schedule minimizes the risks of backups and system overload, ensuring efficient operation and longevity of your septic system.

Your septic system shows signs of failing when you detect noticeable odors and unusual moisture, or overly green patches in your yard. In essence, clear indications such as unpleasant smells, gurgling noises from the plumbing, and areas of excessive vegetation or saturation signal that the system may be compromised. Additional symptoms include slow drainage and standing water near the drain field. These warning signs require immediate professional evaluation to prevent severe damage or environmental hazards.
