"(TL/DR: We are happy with the work Cory did, and I would recommend him for your landscaping needs.) The theme here is "all's well that ends well." Cory is one of the nicest guys you will ever meet, and he's very agreeable to work with. He and his crew work remarkably quickly, too, and the quality of work is very good. The job was not without its hiccups, though. Cory is not a proactive communicator, and that caused us some grief along the way. Without boring you with every detail, Cory and his crew got to work on Day 1, and by the end of Day 2, they had built an entire retaining wall on a line different from the one we'd talked about. He told me he had lain the foundation on Day 1 and, when he didn't hear from me, assumed it was correct and moved on to building the wall on Day 2. Problem is, he didn't inform me that I needed to review his Day 1 work (I never imagined that he would do the work differently than what we talked about when he met me for the initial estimate), or that he would interpret no word from me as acceptance of his work. The result was that he had to deconstruct the wall and then rebuild it along the correct line, which I'm sure was a lot of work, but he did it and did so cheerfully. This kerfuffle was unfortunately repeated, in essence, with the landscape stairs--building, followed by no word from him, followed by silence from me, followed by a discrepancy between what he built and what I wanted. This was especially frustrating, because, after the wall incident, he said he would take photos of the unfinished stairs and send them to me for approval before completing them. But, all's well that ends well: he and I met to discuss the issue, and then he and his crew redid the stairs to my satisfaction. To sum up, my experience with Cory is that he will make judgment calls, build, and hope it works out right rather than consulting you to see what you want and doing it that way (or telling you it can't be done that way for a particular reason). If you have a drawn plan that Cory can refer to, you may not have these issues, and perhaps I should have insisted on drawing him a plan when he didn't insist on having one before beginning work. Or, if you don't work during the day, you could oversee the work and give feedback as it's happening to prevent any issues from arising. But don't expect Cory to be proactive about communication. So, after all that, do I regret getting Cory to do the work? Absolutely not. He got it done quickly, did it well, did it for an excellent price, and went the extra mile to make sure we were happy. And we are. We are very excited about the way things turned out, and we can't wait to use the back yard space that Cory helped us create. I would absolutely recommend him."

FAQs for septic system installation and replacement projects in Chattanooga, TN

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
