"Benjamin Franklin was great to work with. They were quick to respond to my Angi request. They came the next day to provide a quote for installing our water filter and conditioner. When that was accepted They started the job immediately. The whole project was done within 24 hours of my Angi post. Jaime C. Was our technician. His work was impeccable. The end result was better than I had hoped for. I highly recommend Benjamin Franklin Plumbing."

"Drainworks of Columbia CT solved a serious septic system blockage at our home in Hebron when no one else would. After a quick call to set up an appointment Justinâ s team were at our home first thing the next morning. They diagnosed the blockage problem using cameras and newer technology that permits them to work faster and more efficiently than others. Then they brought in a crew and the equipment to fully clean out the blockages and repair our septic system. They worked tirelessly and cheerfully all day in a cold rain until they completed the repairs same day. Wow! Consider me a DrainWorks customer for life."

"When in need of a new septic system to replace an aging cesspool I contacted several advertised septic companies. Site estimates were from $15,000 to $20,000 for a simple installation to $25,000 - $30,000 with difficulties. So, with the information found on Home Advisor we chose Dan Mackin Jr. Construction from Jewett City, CT (860-376-6591 or 860639-7933) whose estimate after examination of the site was $13,200. It turned out the only acceptable area required extensive ledge removal! Mackin Construction removed the ledge at no extra cost. After installation was complete, the area was totally restored to our satisfaction. At no time was there a lack of communication (verbal or digital) between the customer and the contractor. Payoff was $13, 050 because we were credited $150 for parts not needed. BOTTOM LINE: This is one of the last family owned businesses of this kind that deliver a quality product at a fair price!"

FAQs for septic system repair projects in Lebanon, CT

Leach field failure can often occur due to a lack of proper maintenance, hydraulic overload, or environmental factors. When too much water enters the septic system—like running multiple large laundry loads back-to-back—it can overwhelm the leach field. Regular professional inspections, ongoing maintenance, and spacing out high-water-use activities help prevent failure.

A septic tank shows repair needs when noticeable symptoms arise around your home. Noticeable signs include strong sewage odors at fixtures, recurring pipe blockages, pooling water or damp patches near the leach field, and areas of unusually bright green or spongy grass. These indicators confirm that deteriorating components or clogs exist. Monitoring such signs and scheduling timely professional inspections prevents further costly damage.

Adhering to a strict, scheduled maintenance plan prevents septic system repairs. An annual inspection and a pump-out every three to five years safeguard your system’s performance. Additionally, only flushing waste and toilet paper, installing drain filters, keeping nonapproved items out of the system, and avoiding excessive water use help maintain your septic system’s health and efficiency.
